AP 8029. CP 10800, Cuba. E-mail: rayner@ecologia.cu ABSTRACT. Five new species of Paucivena Davis Sau a Tineoidea: Psychidae), P. ferruginea, P. pinarensis, P. fusca, P. cubana and P. orientalis are described from Cuba and compared with relatives. The females of P ferruginea and P. orientalis are described being the first fe- males known within genus; their characteristics confirm the intermediate position of the genus among the American psychids. Notes on natural history of new species (e.g. hosts, habitat) are given as available. Keys for identification of known stages of all Paucivena species are provided. Additional key words: Tineoidea, Psychidae, bagworm, natural history, West Indies. The Neotropical region has the richest Lepidoptera diversity but one of the least studied psychid fauna with only 61 known species (Heppner, 1998; Davis, 2000). This species number is extremely low compared with that of other faunal regions. The Paleartic, for example, has more than 300 decenbed species (Heppner, 1998). Members of this family were last reviewed by Davis (1975) who described two genera and five species from the West Indies. However, none of these taxa was known from Cuba. Recent collections from Cuba, chiefly on the three main mountain chains, have resulted in the discovery of new records including several new species. In this work, five new species belonging to Paucivena Davis, 1975 are described. Keys for identification of known stages of all species and information on natural history are also provided. MATERIALS AND METHODS Individuals of all species, except one whose representatives were taken flying at day, were collected as larvae and pupae in the field and reared in the laboratory. Lab-reared larvae were provided with field collected hosts until pupation. All type material is deposited at Instituto de Ecologia y Sisteméatica (CZACC). Diagnostic morphological characters employed follows Davis (1964, 197: 5) and Henderickx (1982). Setal maps of larvae follow Hinton (1946) and Stehr (1987). Measurements were taken with an ocular micrometer in a Carl Zeiss Stemi 2000 stereoscopic microscope. Interocular index of head was calculated as a ratio between the vertical diameter of the compound eye and interocular distance measured at a point across the frons midway between the base of antennal sockets and the anterior tentorial pits (Davis, 1975): Interocular index= vertical eye diameter/ interocular distance Characters of the two previously known species, Paucivena reticulata Davis, 1975 and Paucivena hispaniolae Davis, 1975, were taken from original descriptions and illustrations. Additionally, one P. reticulata specimen placed at CZACC, was examined. Abbreviations: x- mean, SD- standard deviation, CV- coefficient of variation. RESULTS Paucivena Davis, 1975 This genus is known only from the western part of the cic: Davis (1975) described P. hispaniolae from Dominican Republic, Hispaniola, and P. reticulata from Puerto Rico and Jamaica. In the same work, this author mentioned the possible presence of Paucivena on Cuba. This was confirmed recently by Nuifiez (2004) based on unknown species from Topes de Collantes, in the Cuban central mountains, which are described here. Characters that best define Paucivena males are labial palpi with a single segment not fused, origin of antennal rami at base of each antennal segment, two pairs of tibial spurs on mid and hindlegs, reduced wing venation and the abbreviated genitalia. Females may be recognized by the possession of compound eyes and functional legs, and the lack of antennae and wings. Larvae feed on several hosts including mosses and lichens growing on rocks and bark, and detritus. Paucivena ferruginea Niiiez, new species (Figs. 1, 6, 11, 16, 17, 22, 24, 26, 28-35, 41, 4546, 52) Diagnosis: Paucivena ferruginea male differs from all other Paucivena by its brown coloration with slight ferruginous iridescence. Other diagnostics characters are the acute and heavily sclerotized sacculus and the bifid saccus of its genitalia. Male (Figs. 1, 6, ‘1, 16, 17). Head: brown.

Top- prothoracic leg, middle- mesothoracic leg, bottom-metathoracic leg. Scale= 2 mm. Natural history observations. Larvae were found feeding on mosses, Orthostichidium guyanense (Mont.) V.F. Brotherus (Pterobryaceae) and another unidentified species, on bark of an unidentified bush. Two adults were reared from larvae: a male emerged from the pupa after a month; a female emerged and was observed hanging from distal end of the case. The species was found in two localities with very different vegetation and climatic conditions. Parque Codina is characterized by a secondary and very humid evergreen forest with the lower strata protected by a dense canopy. A dry scrub, included in the mogote vegetational complex, g grows on top of Pico Potrerillo, an enviroment very epaunenl to wind and solar radiation. Distribution (Fig. 52). Known only from two localities at Topes de Collantes region, Trinidad Mountains, central Cuba. Etymology. The species name is derived from the slight ferruginous iridiscence of male wings. Remarks. The female may be separated from that of P. orientalis, n. sp., by its greater size (length 7.5 versus 5 mm), its more elongated genitalia, the presence of JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY only two longitudinal spot bands on tegument (six in the other species) and its unswollen tibiae. Larvae may be recognized by the loss of AF2 on head and the isolation of LA3 on labrum. The larval case is also diagnostic for this species within the genus. Davis (1964, 1975) reported similar cases from Haiti and Trinidad. Davis noted the of these with constructed by species of Epichnopteryx Hiibner and Psyche Schrank, two Old World genera, considering them as a probable introduction from the Old W forld. Larval cases of P. ferruginea prove that this construction pattern is not exclusive to Old World species. similarity cases those Paucivena pinarensis Nunez, new species (Figs. 2, 7, 12, 18, 42, 47, 52) Diagnosis: Paucivena pinarensis males possess a color pattern similar to that of P. cubana, sp. n., P. orientalis, sp. n., and P. reticulata. However, the reticulated pattern is weaker in P. pinarensis due to its more obscure background color. Compared to other Paucivena within this group, P. pinarensis males exhibit several diagnostic characters: absence of saccus in its M1 M243 3A CuA1 1A Cup CuA2 + 11 2a 14 Fics. 11-15.

Natural history observations. The single larva was found on limestone rock near the Taco Taco River shore and its food source can not be accurately identified. In the lab, the larva was fed with several crustose lichens and mosses collected on its substrate. Other larval cases were found on rocks and tree trunks in an old abandoned Botanical Garden (Jardin de Aspiro). The unique adult emerged after a month; emergence took place between 0900 and 1130h. At the Taco Taco River shore secondary remnants of gallery forest are present whereas at Jardin de Aspiro several introduced and native trees grow forming groves separated by cleared areas occupied by camping installations. Distribution (Fig. 52). Known only from two close JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY localities at Sierra del Rosario, Pinar del Rio province. eee The species name is derived from the name of the Cuban province where the type locality, Pinar del Rio, is located. Remarks. The larval case is identical to that of P. cubana. The male pupa may be easily identified by the unique arrangement of a rows on the dorsum of abdominal segments (Table 1 Paucivena fusca Nunez, new species Paucivena sp. n. 1: Nunez, 2004: 155 Figs. 3, 8, 13, 19, 52 Diagnosis.

However, larvae probably use other hosts since cases were found on different substrates at other localities. At the Pico Potrerillo access cases were found attached to rocky walls covered by crustose lichens, at mogote Mi Retiro base they were located on banana plants whereas at Parque Codina they live on trunks of native trees. The single adult emerged after a month as pupa. Bruen cubana inhabits localities with very different vegetation and climatic conditions. At Parque Codina it was found in the lower strata of secondary evergreen forest, a very humid habitat, and at the mogote Mi Retiro base in cultivated land, banana and cotfee (Coffea arabica L., Rubiaceae), close to the mogote rocky wall. On the other hand, Caburni River shores are covered by gallery forest remnants, today dominated by an introduced tree (Syzigium jambos L.., Myrtaceae), whereas at the Pico Potrerillo access cases were attached to rocky walls surrounded by evergreen forest. Distribution (Fig. 52). Known from four localities at Topes de Collantes, Trinidad Mountains, central Cuba. Etymology. The species name is derived from the name of the Cuban island. Remarks. The larval color pattern is identical to that of P. ferruginea; however, differences in chaetotaxy and abdominal coloration are present. Male and female pupae are easily distinguished by the arrangement of abdominal dorsal spines (Tables 1, 2). Paucivena orientalis Ninez, new species Figs. 5, 10, 15, 21, 23, 25, 27, 44, 49, 52 Diagnosis. Adult males of P. orientalis possess a color pattern similar to that of P. pinarensis, P. cubana, and P. reticulata. P. orientalis may be separated from P. pinarensis by its smaller tibial spurs (0.15 versus 0.3 the length of basal tarsal segment), the presence of a saccus in its genitalia and its more distinct FW reticulated pattern. From P. reticulata, it may be distinguish by its smaller eyes (interocular index 0.7 versus 1.1) and tibial spurs (0.15 versus 0.5 the length of basal tarsal segment). From P. cubana it differs by its smaller size (8.29.1 versus 12 mm of wing expanse) and eye size (interocular index 0.7 versus 1.5). Male (Figs. 5, 10, 15, 21). Head: pale g ereyish brown. Anten- nae with 16 segments; lateral pectinations 22.5 times the length of segment. Eyes small, vertical diameter of eye 0.7 the interoc- ular distance. Thorax (Figs. 10, 15): dorsum dark brown; under- side pale greyish brown, inner surface of legs dark brown. Vesti- ture dense, scales hairlike. Tibial spurs approximately 0.15 the length of basal tarsal segments (Fig. 10). Wings thinly scaled. FW variously rounded; pale grayish brown streaked with dark brown scales to form a reticulated pattern; fringe with various tones of brown. Scales at discal cell mostly Sblanceolited and ovobated, with rounded, or rarely acute apices. Venation (Fig. 15) as in P. ferruginea. HW uniform pale greyish brown; fringe with various tones of brown; venation as in P. fusca. Wing ex- panse: 8.2-9.1 mm (x=8.8, SD=0.49 CV=6%, n=3). Abdomen: dorsum dark brown at both ends, remainder pale greyish brown. Vestiture dense, scales hairlike. Genitalia (Fig. 21): tegumen broad, with a pair of sparsely setose apical lobes! Valvae with pulvilli sparsely setose; apex of sacculus armed with three to four spines; cucullus with apex rounded and sparsely setose. Saccus reduced, approximately 0.1 the length of main body. Aedeagus simple, cylindrical, 0.6 times the length of valvae. Female (Figs. 23, 25, 27). Length 5.0 mm. Vermiform. Stramineous with six longitudinal bands of brown spots on dorsum and sides of body. Head (Fig. 23): stramineous, eyes black. Slightly sclerotized. Shape near ovoid (ventral view); eyes compound, well developed, subventral.

Natural history observations. Larvae were collected on substrates covered by several lichens and mosses and on external walls of edifications: thus, this species probably also feeds on detritus. The adult reared from a larva, a female, emerged after three weeks. One case was collected with an egg cluster and 53 larvae hatched 1 May 2004. At Nuevo Mundo larval cases were found on trunks of old isolated Mangifera indica L. (Anacardiaceae) trees, in an abandoned coffee plantation. At Gran Piedra all individuals were located on edification walls. Distribution. Known only from two separated localities at Sierra Maestra, southeastern Cuba (Fig. 52). Etymology. The species name is referred to its distribution range, restricted to the oriental Cuban region. Remarks. The larval case is diagnostic for this species. Although constructed with small dry vegetal fragments like those of P. pinarensis and P. cubana, material is always cut in slender pieces and arranged lengthwise but in a divergent way. Pupae of both sexes are easily distinguished by the arrangement of abdominal dorsal spines (Tables 1, 2). widely DISCUSSION All new species described here fit the genus Rio Taco Taco Jardin de Aspir Topes de , Collantes JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY description. However, interespecific variation in the interocular index was noted with values between 0.7 and 1.5. This is the only character that shows significant deviation. Measurement given by Davis (1975) was 1.1. Deviation in Cuban representatives may be due to differences in daily activity between species. Powell (1973) also used an “eye index” in his study on New World Ethmia Hiibner (Oecophoridae: Ethmiinae). Index values were between 0.9 and 1.2 in moths known or presumed to be nocturnal whereas diurnal species exhibited ratios from 0.7 to 0.8. All adult males of Paucivena species described here were lab-reared, except those of P. fusca that always were collected flying during the day. Data on daily activity of species described by Davis (1975) are unavailable so this matter will only be clarified with future work. The female, described here for the first time, shows characters that confirm Paucivena intermediate position among the American psychids proposed by Davis (1975) based on male characters. Female primitive features are the presence of well developed compound eyes, functional legs and the behaviour of leaving the larval case and climbing on it, as occurs in some primitive Old Word forms (Davis, 1964).

Distribution of Cuban Paucivena spp. Scale bar in kilometers. VOLUME 60, NUMBER 3 the reduced genitalia, the complete loss of antennae and wings and the slightly sclerotized body wall. In the larvae, the color pattern of the head and thorax apparently lack diagnostic value, at least in Cuban species. In P. ferruginea, P. cubana, P. pinarensis and P. orientalis (the last two not described but observed during rearing), the pattern is white to greyish white with dark fuscous longitudinal bands. However, the abdominal integument is differently colored in P. ferruginea (dare brown) and P. hispaniolae and P. cubana (dirty white). Differences in chaetotaxy may be also used for species recognition. Davis (1975) mentions that P. hispaniolae larvae feed on crustose lichens growing on the bark of an unidentified tree. Larvae of Cuban Paucivena feed on a wide variety of hosts including mosses, hepatics, lichens and detritus. All these food preferences have been observed before in the Psychidae (Davis, 1964; Hattenschwiler, 1985; Davis & Robinson, 1998) and perhaps explain in part genus diversification together with geographic isolation. Paucivena appears to be well expanded on Cuba compared to other Antillean islands such as Hispaniola, Jamaica or Puerto Rico. However, this may due to lack of sampling on these islands. In Cuba, more collect effort on Psychidae is also needed. The Nipe-Sagua- Baracoa Mountains, in the northeast part of the island, and other habitats like coastal forests, ultramafic scrub, and white sand savannahs are yet unexplored.

W. HALL Department of Entomology, National Museum of Natural History,Smithsonian Institution, Washington, DC 20560-0127, USA Email: hallja@si.edu ABSTRACT. A new riodinid species, Stalachtis halloweeni Hall n. sp. (Stalachtini), is described from Mount Ayanganna, a tepui in western Guyana. A preliminary hypothesis of phylogenetic inter-relationships within the small genus Stalachtis Hiibner is suggested, based on an informal study of external morphology and male genitalia. Three species groups are proposed, the phlegia, calliope and eute rpe groups, and S. halloweeni is hypothesized to be sister to the re maining me embers of the eute rpe group. Additional key words: endemism, montane forest, morphology, South America Situated in the Pakaraima Mountain the easternmost tepuis in the Guiana Shield. Like the other tepuis in western Guyana and eastern Venezuela, Mount Ayanganna consists of eroded sandstone remnants of the Roraima Formation (MacCulloch & Lathrop 2001), and its isolated high-elevation habitats harbor significant numbers of endemic plants and animals. During the last five years alone, several new endemic species of frogs, snakes and lizards have been described from Mount Ayanganna (MacCulloch & Lathrop 2001, 2002, 2004). During the last ten years, there have been numerous Lepidoptera expeditions to the upland regions of western and southern Guyana (Fratello 1996, 2001, 2003, 2005). In 1999, accompanied by several US and 2 Fics. 1-2. Stalachtis halloweeni adults (dorsal surface on left, rac surface on right). 1. Holotype male, Mount Ayan- ganna, Guyana ( (USNM). 2. Paratype female, Mount Ayan- ganna, Guyana (USNM). Range of western Guyana, Mount Ayanganna (2042m) is one of Guyanan colleagues, S. Fratello led the first Lepidoptera collecting expedition to the upper slopes of Mount Ayanganna. Among the many taxa of butterflies collected there were several new species of Riodinidae, including a new species of Stalachtis Hiibner, 1818 (Stalachtini), although most of these species were represented by only a small number of female specimens. Fortunately, a second expedition to Mount Ayanganna in 2002, by a different team that included one of the 1999 Guyanan expedition members (R. Williams), produced additional — Stalachtis specimens, including males. new This new Stalachtis species is remarkable in several respects. It is the first new species to be described in this small, essentially South American genus of aposematic species for over 150 years, since Westwood (1851) described S. magdalena; it is the first known Stalachtis species to apparently occur exclusively in montane habitats; and its wing pattern differs substantially from that of its congeners. I herein describe this new Stalachtis species and attempt to establish its phylogenetic position within the genus by informally constructing a preliminary hypothesis of phylogenetic relationships for Stalachtis and proposing a new species-group classification.

Williams) (National Museum of Natural History, Smithsonian Institution, Washington, DC, USA [USNM)]). Paratypes: 1d, 12, same data as holotype. 3°, GUYANA: Cuyuni- Mazaruni, Mount Ayanganna, 4500-5500 ft, 5°24.1'N 59°57.4'W, 13-18 Apr 1999 (S. Fratello et al.) (USNM). No additional specimens have been located in the major museums of Europe and North America (as listed in Hall 1999, 2005). Etymology: The name is derived from the middle English word halloween, in reference to the fact that the wing pattern is composed of the traditional orange and black colors of Halloween, and is reminiscent of a carved pumpkin. Systematic placement and diagnosis: Stalachtis (= Nerias Boisduval, 1836) is the sole genus currently treated in the tribe Stalachtini. The family-group name was proposed by Bates (1861), as a subfamily, for an undefined number of genera whose species possessed a “pupa not flattened beneath, secured rigidly by the tail in an inclined position, without girdle”, a set of characters quickly discovered by Bates (1868: 36S) himself not to be phylogenetically informative in the context of the ee classification of the Riodinidae. Stichel (1910-11) used the Stalachtini as a tribal name for the first time (as the Stalachtidi), and followed Bates (1868) in including only Stalachtis within it. Most recently, Harvey (1987) defined the monotypic Stalachtini by the presence of a tuft of long setae around 140 Fic. 4. Female genitalia of Stalachtis halloweeni paratype in dorsal view. Scale bar = 1 mm JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY the posterior margin of abdominal segment eight in males and, to a greater extent, females, and mentioned that its species are unusual in the Riodinidae in having hindwing veins Rs and M, stalked rather than arising separ ately from the discal cell end (Bates 1868: Stichel 1910-11). Additional unique characters that are universal within the Stalachtini include extremely long and weakly bent (i.e. ventrally directed) falces, a complex arrangement of inner valve processes, and a long straight comb of prominently curved, anteriorly directed spines on the aedeagal vesica in the male genitalia (Hall unpubl. data). The new Stalachtis species, S. halloween, all of the above characters. Traditionally, Stalachtis has been treated as eight species (e.g. Stichel 1910-11, 1930-31), although some authors have listed as many as ten species (D'Abrera 1994; Bridges 1994). However, the genus is now justifiably recognized to contain only six species (Callaghan & Lamas 2004). Hemming (1964, 1967) selected the type species of Hiibner's (1818) Stalachtis to be S. phaedusa (Hiibner, [1813]). It is worth mentioning that the name Stalachtis funereus albulus Lathy, 1958, which occasionally appears in the riodinid literature (e. g. Rebillard 1958; D'Abrera 1994; Bridges 1994), seeually refers to a pericopine moth possesses containing 5 (Arctiidae) (Hall unpubl. data). Stichel (1910-11, 1930-31) divided Stalachtis into two sections, the “Adiorati” for S. calliope (Linnaeus, 1758) and S. magdalena Westwood, 1851, in one ee and S. phlegia (Cramer, 1779) (+ S. suwsanna (Fabricius, 1787)) and S. euterpe (Linnaeus, 1758) in another subgroup, and the “Diaphanes” for S. phaedusa (+ S. zephyritis (Dalman, 1823)) and S. lineata (Guérin-Méneville, [1844]). Based on a study of wing pattern and male genitalia characters in all six Stalachtis species, an alternative species-group classification and preliminary hypothesis of phylogenetic relationships for the genus is proposed here. As S. calliope, 8. magdalena, S. euterpe, S. phaedusa and S. lineata all share a pair of large, rounded, inner valve processes, with an elongate, pointed transtilla extending posteriorly between them and across the top of the aedeagus, S. phlegia is hypothesized to be sister to the remaining species in the genus. Stalachtis phlegia has a much smaller pair of inner valve processes, without the intervening transtilla, and has the least derived wing pattern, with a full complement of white basal, postdiscal and submarginal spots. Stalachtis calliope and S. magdalena, like S. phlegia, but unlike any other Stalachtis species, have a complete row of submarginal white spots on the forewing, an orange patch at the base of the dorsal forewing and hindwing, VOLUME 60, NUMBER 3 and an entirely checkered black and white hindwing fringe. Their similar wing g patterns, with mottled orange markings at the base of the forewing and parallel orange bands on the hindwing, shared possession of an upper valve process that is broadest medially (instead of basally in S. phlegia and distally in the remaining three species), and parapatric geographic ranges strongly suggest that they are sister species. Stalachtis euterpe, S. phaedusa and S. lineata appear to form a monophyletic group, as all three species share similarly positioned white wing markings that are consistently formed into rays reread of spots, the absence of an orange patch at the base of the dorsal forewing and hindwing, the absence of a complete row of submarginal white spots on the forewing, largely black wing fringes, and an upper valve process that is broadest distally. As Stalachtis phaedusa and S. lineata both have elongate hyaline rays on both wings they are probably sister species. Stalachtis halloweeni appears to exhibit external pattern characters that are somewhat intermediate between those of members in the calliope and euterpe groups. It shares with the two calliope group species the presence of orange markings at the base of the dorsal forewing, and wath S. magdalena the absence of a lateral white line above as well as below the lateral orange band on the abdomen. It shares with the three euterpe group species a similar pattern of rays at the base of the forewing and particularly the hindwing, even if these are orange instead of white, the absence of a complete row of submarginal white spots on the forewing, and black wing fringes. Based on the above characters, and the fact that S. halloweeni has the full complement of inner valve processes and an upper valve process that is broadest distally, this new species is tentatively suggested to be the most basal member of the euterpe group. The male genitalia of Stalachtis species are rather homogeneous, with the most significant interspecific variation exhibited by the upper and, to a lesser extent, lower valve processes. Although S. halloweeni appears to be most closely related to S. euterpe, its male genital valvae are probably most similar to those of S. phaedusa, but its upper valve process does not have such a prominent ventral protrusion at the posterior tip, and the posterior margin extends at about a 45° angle instead of vertically. Elsewhere in the euterpe group, S. euterpe can be characterized by its dorsal as well as ventral swelling to the distal tip of the upper valve process and atypically small and straight terminal projection, and S. lineata can be characterized by its broadly triangular instead of narrower rod-shaped lower valve process. In conclusion, Stalachtis seems to be best divided 14] into three species groups, the phlegia group for S. phlegia, the calliope group for S. calliope and S. magdalena, and the euterpe group for S. halloweeni, S. euterpe, S. phaedusa and S. lineata. Thus, only two of Stichel's (1910-11, 1930-31) three proposed species groups for Stalachtis appear to be monophyletic. Biology: This new species appears to be restricted to lower montane forest habitats, where it is currently known from between about 1100 and 1700 m. Specifically, the type series was collected in wet, low (canopy approximately 10-15 m), evergreen high-tepui forest, a vegetation type that was described and illustrated by Maguire (1970), Huber et al. (1995) and MacCulloch & Lathrop (2001). Steve Fratello (pers. comm.) observed approximately ten individuals of S. halloweeni on Mount Ayanganna, most of which were probably females, judging by the fact that all individuals captured were of that sex. Within the forest, these individuals consistently flew at about 5 to 7 m above the ground, although two individuals were observed flying only 2 to 3 m above the ground over a patch of low tepui scrub at 1700 m. Individuals were seen flying over a wide area from mid-morning to mid- afternoon, with a rather slow, steady flight, and were not observed alighting or resting. No other Stalachtis species were seen flying in the same habitats as S. halloweeni, but S. phaedusa, S. calliope and S. euterpe have been commonly collected in neighboring lowland areas of Guyana (Fratello pers. comm.). Stalachtis is one of the most well known groups of aposematic riodinids (Seitz 1916-20; D'Abrera 1994). Given that the known caterpillars are gregarious and aposematic (Callaghan 1986), and members of at least some of the known foodplant families (e.g. Simaroubaceae) contain toxic phytochemicals (e.g. Moretti et al. 1982; Polonsky et al. 1984), it seems likely that some or all of the Stalachtis life stages are to some extent distasteful to predators, and pauls may thus be predominantly Mullerian rather than Batesian mimics. However, I am not aware of any sympatric butterflies or moths that specifically closely resemble S. halloweeni. Distribution: Stalachtis halloweeni is curr ently known only from the middle slopes of Mount Ayanganna, in the uplands of western Guyana. However, the geographic range of this species probably extends to neighboring highland areas in Guyana and extreme eastern Venezuela. There continues to be debate about whether most Guiana highland endemics are relicts of a widespread pantepui fauna or descendants of lowland ancestors (e.g. Myers & Donnelly 1996; MacCulloch & Lathrop 2001). Given that all six described Stalachtis species have entirely lowland distributions, the ancestor of S. halloweeni presumably colonized Mount Ayanganna from the surrounding lowlands.

HYDROGRAMMA (MEYRICK) JOHN W. Brown Systematic Entomology Laboratory, P.S.I., ‘Agricultural Research Service, U.S. Department of Agriculture National Museum of Natural History, P.O. Box 37012, W fashington, DC 20013-7012 Email: jbrown@sel .bare.usda.gov ABSTRACT. Auratonota pharata, new species, is described and illustrated from Costa Rica, Panama, Venezuela, and French Guiana. The species is most similar to A. hydrogramma (Meyrick), with which it formerly was confused. It can be distinguished superficially from the latter by the absence of the narrow pale curved band beyond the distal end of the discal cell of the forewing. The male genitalia of the new species differ by a slightly expanded, dorsally convex, and ventrally flattened distal portion of the uncus. The female genitalia possess numerous short curved bands of 5-6 microtrichia around a larger single seta set in a shallow pit on the surface of the middle of the papillae anales compared with the more semicircular bands of microtrichia nearly surrounding the seta in A. hydrogramma. A survey of wing coupling in numerous gen- era of Chlidanotini and Hilarographini revealed that the female frenulum consists of two bristles usually separated throughout their length in all representatives examined in these two tribes; three bristles are present in females of most other Tortricidae. This character state represents an additional putative synapomorphy uniting those two tribes. RESUMEN. Auratonota pharata, especie nueva, es descrita e ilustrada de Costa Rica, Panama, Venezuela y Guyana Francesa. Este especie es mas similar a-A. hydrogramma (Meyrick), con la cual ha sido con tundida. Puede ser identificada de una manera ease de esta ultima por la ausencia de una banda curva fina clara detras de la portedistal de la celda discal de las alas anteriores. La genitalia del macho de la nueva especie puede ser distinguida por la presencia en la partediscal del uncus de una area ligeramente expandida, convexa dorsalmente y plana ven- tralmente. La genitalia de la hembra puede ser distinguida por la presencia de numerosas bandas curvas cortas de 5-6 espinas pequenas arriba de una sola seta en media superficie de los papillae anales en comparaci6n con bandas mas semicirculares de espinas pequenas casi rodeando la seta en A. hydrogramma. Additional key words: Systematics, genitalia, morphology, Costa Rica, Central America, Venezuela, French Guiana, inventory, Chlidan- otini, frenulum Auratonota Razowski is the largest and most diverse genus in Chlidanotini (Tortricidae: Chlidanotinae) with 30 described species (Razowski & Becker 2000, Brown 2005) and numerous undescribed species present in collections. The genus is restricted to the New World tropics, ranging from Mexico and the Caribbean (Cuba, Dominica) south through Brazil. A previously undescribed species of Awratonota has been concealed in entomological collections for many years under the name A. hydrogramma (Meyrick). The similarity of the new species to A. hydrogramma in size, forewing pattern, and genitalia, along with their geographic sympatry, have combined to inhibit their recognition. The two species can be separated by a subtle feature of the forewing pattern, but recently discovered features of the male and female genitalia provide convincing evidence that they are indeed distinct and diagnosable. The purpose of this paper is to name, describe, and illustrate the new species. This work was stimulated, in part, by the desire to associate scientific names with morpho-species collected during the NSF-funded ALAS (Arthropods of La Selva, Costa Rica) project in order to more easily discuss differences and similarities among the tortricid faunas of transect sites (at different elevations) sampled over the course of the project (1993-2005). Dissection methodology followed that presented in Brown and Powell (1991). Images of adults and genitalia were captured using a Microptics digital camera system and enhanced using Adobe Photoshop and Illustrator software. Terminology for genital structures follows Horak (1984). The following Hreuntionsl abbreviations are used for the denotes of specimens examined: AMNH = American Museum of Natural History, New York, New York, U.S.A.; BMNH = The Natural History Museum, London, United Kingdom; INBio = Instituto Nacional de Biodiversidad, Santo Domingo de Heredia, Costa Rica; UCB = Essig Museum of Entomology, University of California, Berkeley, USA; and USNM = National Museum of Natural History, Washington, DAG WESFA. Auratonota pera Brown, new species (Figs. 2, 4, 5) Diagnosis. Among Hered species of Auratonota, A. pharata is most similar to A. hydrogramma in forewing pattern, size, and genitalia. However, the latter is superficially distinguishable from all described congeners, including A. pharata, by the presence of a slender, pale, arched fascia in the subterminal region of the forewing that roughly parallels the apical half of the termen, intersecting the costa subapically (Fig. 1); the fascia is lacking in A. pharata (Fig. 2). The male genitalia of A. pharata can be diganeaished from those of A. hydrogramma by the shape of the distal one- fourth of the uncus: attenuate and apically pointed in A. 144 hydrogramma (Fig. 3); slightly broadened, convex dorsally, and flattened ventrally in A. pharata (Fig. 4). The female genitalia are extremely similar in both but can be distinguished by a subtle feature of the papillae anales. In A. pharata microtrichia on the internal, middle portion of the papillae anales are arranged in short, slightly curved bands of 5-6 immediately dorso- posterad of a small, pale-colored pit from which arises a single larger seta (Fig. 5). In A. hydrogramma microtrichia are arranged in circular or semicircular bands of 8-9 nearly surrounding a more rounded pit (Fig. 6). Awratonota pharata also is similar superficially to A. aporema (Dognin), described from Colombia, but has a considerably smaller forewing length (mean 11.9 mm for pharata vs. 15.9 for aporema) and lacks the yellow-gold scaling a the forewing pattern elements of A. aporema; the latter feature is more characteristic of members of Psewdocomotis Brown (Chlidanotini), with which A. aporema is more similar superficially.

Distribution and Biology. Awratonota pharata is recorded from Costa Rica, Panama, Venezuela, British Guiana, and French Guiana. Although it appears to be a species of the lowlands (i.e., below 500 m), it has been recorded on several occasions at Rancho Grande, Venezuela, at 1100 m and once in British Guiana from 660 m. During a multi-year survey in Costa Rica along an elevation transect, specimens were collected at 50-150 m (n = 4), 250-350 m (n = 1), and 450-550 m (n = 4), with none recorded from 1000, 1500, or 2000 m. Adults have been recorded in January through March, and June through November. A female collected by J. Powell in January 1998 at La Selva, Costa Rica was confined in a plastic vial where it laid several huge, bulky eggs, 3.3 x 2.8 mm, ca. 10 times the size of comparable-sized tortricine females (J. Powell, pers. comm.). First instars likewise were large, 2.83.0 mm in length. Various leaves, synthetic diet, and raw carrot were offered to the larva; the last has been used successfully with other “borers” such as Hepialidae. The only feeding was by one larva on the carrot, and it ceased to feed before reaching second instar. Etymology. The specific epithet is from the word “pharate,” meaning cloaked or hidden. Auratonota hydrogramma (Meyrick, 1912) VOLUME 60, NUMBER 3 (Figs. 1, 3, 6) Cnephasia hydrogramma Meyrick, 1912: 683. Eulia hydrogramma: Clarke, 1958: 128. Auratonota hydrogramma: Razowski, 1987: 62; Brown, 1990: 156: Powell et al. 1995: 151; Razowski & Becker, 2000: 1151; Brown, 2005: 144. Auratonota hydrogramma was described from a single specimen from Dutch Guiana (= Surinam) (BMNH). The adult and male genitalia of the holotype are figured by Clarke (1958); Razowski & Becker (2000) provided a color illustration of an adult and line drawings of the male and female genitalia. Based on material in several museum collections (AMNH, BMNH, INBio, USNM), it has been recorded from Costa Rica, Panama, Colombia, French Guiana, British Guiana, and Ecuador and at many of the same localities as A. pharata (e.g., Costa Rica, Estacion Biologica La Selva; Panama, Barro Colorado Island; French Guiana, St. Jean, Rio Maroni). Razowski & Becker (2000) reported it from Brazil. As is the case in A. pharata, A. hydrogramma appears to be a species of the lowlands, rarely collected above 600 m. During the multiple-year transect surveys of the ALAS project in Costa Rica (1993-2005), A. hydrogramma was collected only at the 50-150 m elevation site. Auratonota hydrogramma can be distinguished superficially from all other congeners by the presence of a narrow, curved, pale fascia in the apical region of the forewing. The male genitalia (Fig. 3, image of USNM slide 84889, Panama; n = 6) are slightly smaller and have a slightly broader base of the saccus than those of A. pharata; but the most conspicuous feature that distinguishes the two species is the pointed tip of the uncus of A. hydrogramma. The papillae anales (Fig. 6, image of JWB slide 745, Costa Rica; n = 2) of A. Iu jd Onno also have the tiny curved bands of microtrichia described above for A. pharata, but in A. hydrogramma the bands are more semicircular and nearly surround a rounded, pale-colored pit. Even though only two females of each species were examined, these differences appear to be consistent. Holotype ¢, Dutch Guiana [Surinam], Paramaribo, Aug 1892 (BMNH).

DISCUSSION In most tortricids, the setae of the papillae anales arise from variably sized, papillose protuberances. In A. hydrogramma and A. pharata these protuberances are present only around the perimeter of the papillae anales, with most of the papillae anales bearing short, thin setae from weakly depressed pits bordered by a straight or curved row of microtrichia. This unusual arrangement of setae also is present in A. petalocrossa and is suspected to occur in A. aporema—these four species are all similar in size, forewing markings, and structures of the male genitalia. These features are easily observed using a dissecting microscope because of the large size of the moths. In Auratonota dominica Brown there is a similar configuration of setae but at a much smaller scale, requiring observation using a compound scope. Similar arrangements of setae appear to be lacking in other Chlidanotini genera examined, leading to the possibility that it is a feature unique to Auratonota. The structure of the frenulum in the female of A. pharata, with two distinct bristles clearly separated at their base, is somewhat unusual in Tortricidae where the female frenulum typically consists of three bristles, usually coalesced basally. A two-bristled frenulum was hypothesized by Komai (1999) to represent a syanpomorphy for Shee ra Herrich-Schaffer and 146 JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY 2.0 mm Fics. 1-2.

However, to my knowledge it previously has not been reported in Chlidanotinae. A survey of various (but not all) genera within that subfamily revealed that all Hilarographini and Chlidanotini examined have a female frenulum that consists of two bristles, potentially representing an additional synapomorphy for that putative sister-group pair. Its distribution is less consistent within Polyorthini where females of Polyortha Dognin, Ardeutica Meyrick, Lopharcha Diakonoff, and Cnephasitis Razowski have two bristles and those of Isotrias Meyrick, Olindia Guenée, Chlorortha Razowski, Ebodina Diakonoff, and Lypothora Razowski have three; it is variable among females of Histura Razowski.

SIMMONS Dept. of Biology, University of North Dakota, P. O. Box 9019, Grand Forks, ND 58202, rebecca.simmons@und.nodak.edu ABSTRACT. Psoloptera Butler, a genus of three species within Euchromiini, was previously described based on wing venation and overall appearance, resulting in a polyphyletic assemblage. Here, species of Psoloptera are redescribed and illustrated. One species, P. aurifera (Her- rich-Schaffer) , is transferred to Calonotos Hiibner as a new combination. Comparisons of male and female genitalia of Psoloptera with other historically associated genera refute previous hypotheses on euchromiine relationships. Additional key words: Neotropical fauna, taxonomy, mimicry The tribe Euchromiini (Lepidoptera: Arctiidae: Arctiinae) consists of highly specialized mimics of Hymenoptera, Diptera, and Coleoptera. This specialized mimicry has confounded efforts to classify these animals; distantly related species may mimic the same model, resulting in a convergence in appearance. Historically, classifications were formed based on overall wing venation and similar coloration. This practice often results in polyphyletic genera. One such genus is Psoloptera Butler (Figs. 1-3). Butler (1876) erected Psoloptera, and originally placed two species in the genus, P. thoracia (Walker) and P. leucosticta (Hiibner). Later, Schaus (1894) described P. basifulva, citing that it was allied to P. thoracia (Walker), the type of Psoloptera. Hampson (1898) placed P aurifera (Herrich-Schiffer) in Psoloptera because of similar overall appearance and wing venation. Butler (1876) placed Psoloptera in the subfamily Euchromiinae (= Euchromiini of Jacobson & Weller 2002), and stated that it was closely allied to Calonotos Hiibner and Amycles Herrich-Schiffer (= Pompiliodes Hampson 1898; = Sphecosoma Simmons & Weller in press), but distinct because of its plumose antennae and different hindwing venation. Hampson (1898), in his phylogeny of the Syntominae, placed Psoloptera as ancestral to Metaloba Hampson, and sister to Calonotos, Chrysocale Walker, Micragyrta Butler, Mystrocneme Herrich-Schaffer, Orcynia Walker, Paramya Druce (= Methysia Butler; Simmons & Weller in press), Sawrita Herrich-Schaffer, and Scena Walker. Forbes (1939a) allied Psoloptera to Saurita based on wing venation, and noted that the genera differed in the beanehine of the radial veins. Though a consensus of these views indicates a close relationship with Calonotos, this assertion has never been examined using any characters other than external features. This paper redescribes Psoloptera and revises its composition by transferring one species to Calonotos. The individual species are diagnosed and figured. The genitalia of both sexes of all Psoloptera species are figured for the first time here as well. Relationships of Psoloptera and other euchromiines are discussed. 3 Fic. 1. Male P. basifulva Schaus, type specimen (USNM). Fic. 2. Adult P leucosticta (Hiibner), lectotype specimen (USNM). Fic. 3. Male P pei ia (Walker), type specimen (BMNB). MATERIALS AND METHODS Standard genitalic and whole-body dissections were performed (Winter 2000). Bodies were softened in warm 10% KOH for 5-15 minutes and then cleaned (scales and viscera removed) in several rinses of 30-40% 150 ethanol. Structures were stained with chlorazole black E (Sigma, St. Louis, MO) dissolved in distilled water (saturated). Specimens were viewed in 30-40% ethanol. Wings were bleached and then neutralized with dilute acetic acid. They were then rinsed in distilled water, and stained overnight with Eosin Y (1% in distilled water; Fisher Scientific, Pittsburgh, PA). mounts of wings, abdominal pelts, appendages, genitalia Permanent slide and thoraces were made with Euparol (Bioquip, Rancho Dominguez, CA). Male-female pairs of each species of Psoloptera (sensu Zerny 1912) were dissected to describe genitalia. These species included P. thoracia (Walker), P. awrifera (Herrich-Schiffer), P basifulvua Schaus, and P. leucosticta Hiibner. Camera lucida drawings were made from these preparations. Forewing measurements were made from specimens representing each species of Psoloptera. Type specimens for P. aurifera (BMNH), P. basifuloa (USNM), and P. thoracia (BMNH) were examined to verify species identifications. Genera previously associated with Psoloptera were examined to identify putative sister taxa. Male and female genitalia were examined for Calonotos phlegmon (Came: r), Chrysocale principalis (Walker), Metaloba argante (Druce), Methysia notabilis (Walker), Orcynia calcarata Walker, Saurita cassandra (L.), Scena styx (Walker), and Sphecosoma aliena (Walker) Terminology for abdominal and genital morphology follows Klots (1970) and Forbes (1939b). Collections consulted include BMNH, the Natural History Museum, London (M. Scoble), and NMNH, National Museum of Natural History, Smithsonian Institution, Washington, D.C. (D. Harvey). RESULTS AND DISCUSSION Psoloptera basifulva, P. and P. thoracia are medium-sized black moths with lateral white spots on the first abdominal Species leucosticta, composition. segment, which may mimic a wasp waist (Weller et al. 2000). Upon examination of Psoloptera species sensu Hampson, I found that P. basifulva, P. leucosticta, and P. thoracia can be distinguished from P. aurifera by both genitalic and nongenitalic characters. Psoloptera aurifera is colored metallic green and is larger than the other species of Psoloptera. Further, P. aurifera males have an enlarged juxta bearing large spines, bilobed valves, and a trilobed uncus (Fig. 4). These characters are not shared with the other members of Psoloptera (see following species descriptions), but are diagnostic for Calonotos males. Based on these observations, I propose the following change: P. aurifera (Herrich-Schiffer), 1854 = Calonotos aurifera (Herrich-Schiaffer), new combination JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY Phylogenetic placement. In Euchromiini, male genitalia are useful for assigning species to genera, grouping genera, and for verification of tribal affiliation. Psoloptera shares genital features with some other euchromiines: projections on the tegumen, slightly bilobed valves, and enlarged juxta. C alonotos phlegmon, Chrysocale principalis, and Metaloba argante share an enlarged juxta with spines, as in Fig. 4. This character is also present in Macrocneme Hiibner and certainly represents a synapomorphy for this group of genera (Deitz 1994). Methysia notabilis appears to have highly specialized genitalia with trilobed valves and a spirelike juxta (figured i in Simmons & Weller in press). Males of Saurita cassandra, Scena styx, and Sphecosoma aliena do not have genitalia similar to Psoloptera males (not figured). The valves of Orcynia are bilobed, while those of Psoloptera are unilobed; however, Orcynia calcarata has projections on the tegumen similar to those of Psoloptera and its juxta is slightly butterfly-shaped. Fic. 4. Calonotos aurifera (Herrich-Schiiffer), male genitalia. J = juxta, U = uncus, V = valve. As in other Lepidoptera, the female genitalia of Euchromiini tend to be more conserved than those of the males. Psoloptera females have genitalia with two signa placed opposite each other on the corpus bursae and an accessory bursa originating from the ductus bursae (Figs. 8, 11, 14). These traits are shared with other euchromiines examined here including Calonotos phlegmon, Chrysocale principalis, Metaloba argante, and Saurita cassandra. Based on these observations, Butler's (1876) placement of Psoloptera in Euchromiini VOLUME 60, NUMBER 3 is justified. Metaloba seems to be related to Calonotos, Chrysocale, and Macrocneme because of the presence of a knob-shaped projection on the antevagellar plate, which is not found in Psoloptera. The sister taxon of Psoloptera is probably not Saurita, as proposed by Forbes (1939a) or Calonotos (Butler 1876, Hampson 1898). Female Orcynia possess a ridged bursae, like that of P basifulva (Fig. 8), but the signa differ. Although the male and female genitalia are not identical to those of Psoloptera, Orcynia seems to be the most likely candidate for the sister taxon. This relationship remains open to further exploration with other data, such as molecular or larval characters. Taxonomy. Here, I redescribe Psoloptera and provide illustrations of the habitus, wing venation, and male and female genitalia of its three species. Psoloptera Butler, 1876 Psoloptera Butler, 1876: 369.

Species of Psoloptera are easily distinguished from each other by habitus and male and female genitalia. The larval host plants and stages are not known. Tymbal organs are present, indicating that ultrasound is utilized for either defense or intraspecific communication; they do not appear to be sexually dimorphic.

MILLER Department of Entomology, University of Minnesota, St. Paul, Minnesota 55108 email: milleOl4@umn.edu ABSTRACT. Mating and oviposition of the forest tent caterpillar, Malacosoma disstria (Hiibner) (Lasiocampidae), were studied in two sites ~2 ha each at levels 1-5 m above the ground, and adult congregation at lights was studied in brightly lit town districts. The observations were made near or at Ely, St. Louis Co., Minnesota, in the latter years of an outbreak peaking during 1999-2003. Descent of the nomadic larvae from the forest canopy to less defoliated vegetative strata for feeding and cocooning later e abled mating to be observed conveniently from the ground. Adult activity began or intensified at ~5:30 pm CDT, when males vigorously sought mates in foliage harboring cocoons. Mating pairs were captured and caged in jars containing a host branchlet for oviposition; mean duration of copulation was 202 min. Captive mated females always oviposited the morning after mating; mean duration of oviposition was 88 min. Dispersal behavior always preceded oviposition. Five new oviposition hosts were recorded. Naturally deposited egg rings were found most often on branchlets oriented nearer horizontal than vertical. Females congregating in brightly lit districts were usually gravid, but seldom oviposited. Additional key words: Malacosoma disstria, Lasiocampidae, defoliation. In northern Minnesota and elsewhere, the forest tent caterpillar, Malacosoma disstria (Hiibner) (Lasiocampidae), builds up periodically to outbreak densities (Witter 1979). During Minnesota outbreaks, quaking Populus tremuloides — Michx. (Salicaceae), and most other broad-leaved trees and shrubs except red maple, Acer rubrum L. (Aceraceae), are severely defoliated. Red maple contains an antifeedant (Nicol et al. 1997), but the nomadic larvae readily spin cocoons among its leaves. The forest tent caterpillar is univoltine, and the larvae hatch in spring at host bud-break (Batzer and Morris 1971). Many thousands of hectares of forest, primarily quaking aspen, were defoliated in the outbreak that peaked during 1999-2003 in northern Minnesota when this study was done (Minnesota Dept. of Nat. Res. For. Ins. Disease Newsletter 1999-2004). Although defoliation seldom kills trees, it reduces their wood- volume growth, and the larvae are considered a nuisance by landowners and outdoor recreationists (Duncan et al. 1956). The eastern tent caterpillar, Malacosoma americanum (Fabricius), also occurs in Minnesota (Stehr and Cook 1968), but mostly in the eastern part of the State, and it was not seen in the outbreak area. Fitzgerald (1995) provides an exhaustive compendium of information for all Malacosoma. At low, nonoutbreak densities, forest tent caterpillar adults mate high above the ground in the forest canopy; during outbreaks they mate on lower, understory vegetation. Mating nearer the ground occurs because larvae descend to less defoliated strata to find food and cocooning sites (Batzer et al. 1995), and males concentrate their search for mates where female cocoons occur. The larvae require angled surfaces for aspen, cocooning, and they commonly create cocoon structures by drawing and spinning leaves together (illustrated by Batzer and Morris 1971 and Fitzgerald 1995, p. 60). In this study, many cocoons were spun on herbaceous plants of the ground stratum as well as shrubs. The downward shifting later enabled mating to be conveniently observed from the ground. Previous reports touch on topics treated here. Bieman and Witter (1983) described field mating behavior at low and high levels of mate competition, reflecting low and high population densities. Stehr and Cook (1968) Bored that forest tent caterpillar oviposition proceeds helically and in a layer one egg deep. Shepherd (1979) reported daily rhythms of male and female activity. Hodson (1941) noted adult congregation at town lights. As elaborated in the discussion section, the present study supplies more or different details about these and related topics. MATERIALS AND METHODS This study was conducted near and in the town of Ely, St. Louis Co., Minnesota. Mating and oviposition were observed in two multilayered stands =40 yr old. Overstories in these stands were dominated by quaking aspen, but scattered examples of other tree species were present, in descending order of abundance, balsam poplar, Populus balsamifera L. (Salicaceae); red pine, Pinus resinosa Ait.; jack pine, P. banksiana Lamb.; eastern white pine, P. strobus L. (Pinaceae); white birch, Betula papyrifera Marsh. (Betulaceae); and balsam fir, Abies balsamea (L.) Mill. (Pinaceae). The understories were dominated by willow, Salix sp. (Salicaceae), but contained scattered examples of other species, in descending order of abundance, red-osier dogwood, VOLUME 60, NUMBER 3 Cornus stolonifera Michx. (Cornaceae); speckled alder, Alnus rugosa (Du Roi) Spreng (Betulaceae); pin cherry, Prunus pennsylvanica L. (Rosaceae); beaked hazel, Corylus cornuta (Marsh.) (Betulaceae); and American cranberrybush, Viburnum trilobum Marsh. (Caprifoliaceae). The vertical range of observation was 1-5 m above ground, and the sites were each =2 ha. Copulating pairs captured in late afternoon were caged in wide-mouthed, 1-liter glass jars with gauze- covered tops containing an aspen or willow branchlet 3-6 mm in diameter. Cages were moved in the evening to a darkened basement with temperatures constantly at 17-19°C, which approximated cool, outdoor evening temperatures. Cages were returned in the morning to shaded outdoor spaces where temperatures ranged 19-26°C. Observations of copulation and oviposition durations were made at <30-min intervals. Gender identification of adults was based on antennal rami, which are =2x longer in males than in females. Males also are noticeably smaller than females (sample measurements given later). Early in the study, active males were netted and released after their gender was confirmed (n> 20). Females were dissected for verification of their gravid or spent condition. Egg fertility was determined by the presence of embryos. Egg numbers/ring were estimated as described by Witter and Kulman (1969), and spumaline—the frothy substance that covers egg rings—was removed as these authors recommended by brushing with a discarded toothbrush. Forewings were removed for accurate length measurement. Angles of egg-bearing branchlets in the field were referenced to horizontal and were estimated with a large protractor. All clock hours refer to Central Daylight Time. Statistics were computed with SYSTAT ( 1992) software, except for G,,, which was computed according to Sokal and Rohlf “C1981). The abbreviation SD refers to standard deviation. Mean daily temperatures during the late larval stage were computed from daily maxima and minima recorded at the Winton meteorological station <5 km from Ely (Minnesota State Climatology Office 2005). RESULTS Mating. The first adults of the flight season were males, as the species is protandrous. Throughout daily adult activity, starting or intensifying ppieally= ~5:30 pm, males visible by the hundreds in any directional view flew vigorously and constantly in vegetative strata containing cocoons. They flew mainly in a zone within <0.5 m ae tree and shrub canopies, circling , Zigzagging, alighting and crawling along branchlets before taking flight again if they did not find an opportunity to copulate. The number of active, searching males around foliage that contained cocoons was ~4x that around foliage that contained no cocoons. On windy evenings, males confined their activity closer to canopies. During two cool, rainy, late afternoons with ambient temperatures <15° C, only a small fraction of the males known to be present were active. Many female pupae appeared to emit their calling pheromone (Struble 1970) before they completed eclosion, as up to 6 males often concentrated activ ity around a single cocoon until the aia eclosed. Males copulated with such females within 1-2 sec after the tip of the female abdomen cleared the cocoon. The wings of such females inflated during copulation. Most mating pairs were found within 10 cm of a cocoon structure presumed to be that of the female, and meconium was often seen on such structures. Some copulating females walked several cm as they were being observed before capture, and because of their larger size pulled the smaller males along. None of the females observed in this study attempted to fly during copulation. Females did not always begin calling before completing eclosion. The locations of two such females found resting quietly on cocoon structures were marked for continuing observation during the evening. At first, captured males released within centimeters of these females flew away. However, by onset of darkness both females were in copula, apparently having eventually emitted their calling pheromone. The sexes were always positioned end to end during copulation. A total of 69 pairs were seen in copula during this study, of which 48 were successfully caged for further observation. Some copulating pairs separated on capture, presumably because copulation had just begun or was nearly completed. Copulating pairs were seen in the field as soon as daily male activity commenced and pairs known to be newly copulating were captured as late as 9:30 pm. Neither active males nor mating pairs were seen during early dawn hours, presumably because of too cool temperatures. Caged pairs remained in copula following capture for 150-255 min, averaging 202 min (n = 10), but it should be noted that beginning and ending of copulation was not always precisely timed, and that some durations are subject to an error of +30 min. Copulating pairs occurred on all the trees and shrubs named earlier, including the conifers. None of the conifers had been fed on, but they provided cocooning sites under conditions of extensive foodplant defoliation. Based on forewing lengths—a proxy for body size—there was a statistically significant relation between gender body sizes of naturally mating pairs: forewing length av eraged 16.8 + SD 1.42 mm for and 12.4 + SD 1.05 mm for their 0.49, df = 23, P = 0.013). femaleck mates (Pearson's r = 158 Oviposition. As in other species of Malacosoma, the forest tent caterpillar deposits its eggs in one batch during one oviposition event unless disturbed during the process. Of the 48 captive mated pairs, 88% of the females began ovipositing the day after copulation, most starting in early morning. The earliest an oviposition was completed was 7:05 am. Other females began ovipositing later, the latest at noon. If not ovipositing the day after copulation, captive females failed to do so entirely. Duration of individual ov iposition in captiv ity monitored during daily hours of observation, which began at 7:00 am, need 65-134 min, averaging 88 min (n = 11). Shorter and longer oviposition durations were associated with smaller and larger egg rings, which imply smaller and larger females and cooler and warmer ambient temperatures. Just before beginning to oviposit, captive females always exhibited dispersal behavior. For 5-15 min they flew upward and around inside their cages. Further, naturally deposited egg rings were never observed near cocoon structures (n = 74). After attempting to disperse, females became quiet, positioning themselves more or less diagonally on the caged branchlet head up with wings partly spread, and extended abdomenal tips around the branchlet nearly 180° before starting to oviposit. As they oviposited, they gradually moved around and down the branchlet, coating eggs and the egg ring surface with spumaline. The second tur of the egg ring was aligned with the first so that the top margin aries seldom haa gaps (Fig. 1d). By the sila of had been deposited and the females were standing on the egg ring surface. branchlets during oviposition were clockwise in 12 cases (60%) and counterclockwise in 8 (40%), reversals during the process, oviposition, several turns of the egg ring Directions of female progression around Q with only 3 2 from clockwise to JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY counterclockwise, and 1 the opposite.

Depending on female size, number of eggs, and branchlet diameter, rings consisted of up to five turns (Fig. la, c). After spumaline removal, margins between turns were not evident. After two days of rainy, windy weather, an increase in irregularly deposited eggs was evident in field egg rings presumably because oviposition had been interrupted by such weather (Fig. le). Spumaline was more or less clear when dispensed, but darkened after =24 h. For egg rings deposited in captivity, number of eggs/ring av eraged 285 + SD 112 and for those deposited naturally, 246 + SD 66, and the difference was not significant (Student's t = 1.20, df = 13.8, Based on 5-39 eggs/ring separate variances, P = 0.25). B ggs dissected in late July contained fertile eggs, with an average of 94% of dissected eggs/ring fertile (n = 14). Corresponding values for eggs collected in the field were 100 and 98% 39). These differences between captive and field eggs were close and inferred to be nonsignificant statistically. Species on which naturally deposited egg rings were found included quaking aspen (76%), willow (12%), with the remainder (12%) on red osier dogwood, balsam poplar, beaked hazel, speckled alder, pin cherry, and American cranberrybush (n = 72). and early August, 94% of rings (n = Fic. 1. Delineated margins of the band or bands of eggs in egg rings of the forest tent caterpillar on aspen branchlets. Delineation is based on seams in corresponding spumaline deposition. In the absence of female disturbance, oviposition proceeds in a down- ward helical manner. VOLUME 60, NUMBER 3 Branchlets on which egg rings were found in the field ranged 2-6 mm in diam. Orientation of egg-bearing branchlets in the field tended to be nearer horizontal than vertical. All 5 samples of 28-74 branchlets containing naturally deposited egg rings in late July and early August were distributed similarly in each sample among three equally progressing angle classes. When pooled, 50% were on branchlets angled 0—30° relative to horizontal, 18% on those 30-60°, and 32% on those 60-90° (n = 291), with departure from a no- erence distribution highly significant (G,,, = 42.9, df = 2, P < 0.001). The ciecrinntion aes 0-90° ane was backward-J-shaped. Adult congregation at lights. Like many moths, forest tent caterpillar adults are photopositive. During flight periods, thousands of adults congregated near streetlights and on brightly lit exterior walls of buildings in towns in the outlines area. In Ely, a few c congregated males had frayed wings, indicating much flight history, but the females showed little or no wing wear. The source was almost certainly infested quaking aspen that were <l km distant. Once congregated, the adults remained notably inactive, and seemed to be present night and day until dying or becoming prey of birds and bats. Both genders seemed equally represented, but copulating pairs were seldom seen. Eggs were sometimes seen on building walls, but were scarce relative to the numbers of females present. Congregated females collected at various times of day for close examination came from the 400-600 and 900 blocks of Sheridan Street in downtown Ely. Their yearly forewing lengths during 2000-2003 averaged 20.0, 18.9, 19.1, and 18.9 mm, respectively, Sade appeared to indicate temporally decreasing body size (F = 13.5, df = 3, 166; P < 0.001). Corresponding percentages that were fully gravid were 96, 90, 97 and 58. DISCUSSION Mating and oviposition. The present study indicates strongly that the vegetative stratum in which most mating occurs is the one containing the most cocoons. The high frequency with which males were observed to copulate with females at the moment of female eclosion is more likely to occur at high than at low population densities, and was observed earlier in Minnesota (Hodson 1941, Bieman and Witter 1983). Female calling pheromone doubtless stimulated such intense male activity. Bieman and Witter (1983) also reported that some males lingered near empty or parasitized cocoons, as well as brown objects, which suggests they also use visual cues. Typically, fernales eclosed and copulated in late afternoon and evening, and oviposited early the next day. The absence of early morning flight activity in this study is not surprising for northern forest tent caterpillar populations. Shepherd (1979) also reported little or no male activity near dawn in Alberta and British Columbia, and found that males ceased flying at <11°C. Such temperatures were common near dawn in the present study. Daily patterns of male activity, female eclosion, and evening female calling closely match those reported by Shepherd. Shepherd (1979) and Bieman and Witter (1983) also reported attempted dispersal by newly mated captive females. Lack of proximity between naturally deposited egg rings and cocoon structures is further evidence of preoviposition dispersal. Positive and significant correlation between gender body sizes of mating pairs indicates that the sexes do not mate randomly with respect to size. Reasons for this are unknown, but one might speculate that larger males out-compete smaller ones to mate with larger females. The mean duration of copulation observed in captivity, 202 min, is near the mean duration of 197 min extracted from Table 1 in Bieman and Witter (1983) for their high population density. Highly variable numbers of eggs/ring averaging 285 in captivity did not seem to differ significantly from the similarly variable mean of 246 observed in the field, nor did the apparent fertility means of 94% in captivity differ significantly from the corresponding 100 and 98% Obeenednnithe Gelder higher and lower fertilities were recorded earlier in Minnesota (Witter and Kulman 1972). After close observation confirmed the helical pattern of oviposition reported by Stehr and Cook (1968) and revealed corresponding seams in spumaline deposition, it became possible to reconstruct the course of oviposition in detail (Fig. 1). Of naturally deposited egg rings found at study sites, 88% were on quaking aspen ena Rvillow. The remaining 12% were on 6 lesser utilized oviposition species, of which 5—red-osier dogwood, speckled alder, balsam poplar, beaked hazel, andi American cranberrybush— were absent from Fitzgerald's (1995) foodplant tabulation for the forest tent caterpillar and other Malacosoma. (Flowering dogwood, Cornus florida L.. an occasional foodplant of southern populations [Goyer et al. 1987], was presumably omitted accidentally from the tabulation.) The new oviposition host records reported here involved no more than 2 egg rings/host, and they are probably explainable by the presence of these plants in areas of high forest tent caterpillar population density. The backward-J- shaped distribution of angles of branchlets bearing naturally deposited egg rings 1-5 m above the gr ound is reported here for the first time. Its 160 significance, if any, is unclear. One possibility is that branchlets nearer horizontal than vertical—where most egg rings were deposited—may be more abundant in midcrowns especially of the overstory and thus provide larvae easier access to the larger foliage volumes at midcrown. Adult congregation at lights. Hodson (1941) earlier reported adult congregation at town lights where the nearest source infestations were several kilometers distant. In the present study, sources were sl km distant. Such short-range attraction to lights at high population densities does not seem surprising. Female movement to lit areas probably occurred during the evening after late-afternoon eclosion and mating. Most congregated females were gravid, and while their status with respect to mating is unknown, they seem likely to have already mated because of the generally assiduous male pursuit. Congregation results in little reproduction because females do not appear to return to foodplants. The paucity of eggs at lights may result from lack of suitable oviposition sites (branchlets). The decreasing yearly body sizes of congregated females during 2000-2003 may be explainable by either or both of two effects: decreasing diet quality with repeated foodplant defoliation, and the generally inverse relation between body size and direction of temperature difference during late larval development (Miller 2005). During late larval development, 10-19 June, in 2000, when female forewing length was greatest, daily mean temperature averaged a cool 12.4°C, whereas in 2001-2003, when female forewing length decreased, daily mean temperature was higher by an average of 4.4°C. Less common than adult congregation at lights is convective transport of adults in the turbulent air of cold fronts for hundreds of kilometers in a few hours as Brown (1965) reported in Alberta and elsewhere. The population dynamics significance of convective transport is unclear as the gravid and mated statuses of transported females have not been reported. LITERATURE CITED Batzer, H. O. AND R. C.

WRIGHT 3349 Morrison Ave., Cincinnati, Ohio 45220-1430, USA email: wrightdj@fuse.net ABSTRACT. Eucosma haydenae, new species, is described from Iowa and Illinois. This species, which seems to be a tall grass prairie obligate, is similar in appearance to E. rusticana (Kearfott) but is much smaller. A review of rusticana is included, and illustrations are provided for the adults and genitalia of both species. Additional key words: Eucosmini. The once pervasive tall grass prairie of the North American Midwest is now reduced to a scattered assortment of small disjunct patches, but those remnants still harbor insects that are rarely encountered elsewhere. This paper proposes a name for one such insect, a small brown moth described below as Eucosma haydenae, new species. It was discovered during faunal surveys in five prairie preserves, one in northeast Iowa, four in the vicinity of Chicago, Illinois. In general appearance it is most similar to Eucosma rusticana Kearfott, but the two species are separated easily by their marked difference in size. Eucosma rusticana is distributed widely in eastern North America but is rather poorly represented in collections. Kearfott (1905) described the species based on six specimens. Klots (1942) reported two syntypes in the American Museum of Natural History (AMNH), including one labeled LECTOTYPE, a designation he attributed to Heinrich (1923). I examined the lectotype. The second syntype in the AMNH, reported by Kearfott (1905) from Algonquin, Illinois, was not found. I also examined four syntypes at the United States National Museum (USNM). MATERIALS AND METHODS This study is based on an examination of 97 adult specimens and 10 genitalia preparations from the following collections: AMNH, Loran D. Gibson, Todd Gilligan (TG), Mississippi Entomological Museum (MEM), USNM, Ron Panzer, and Donald J. Wright (DJW). Forewing length (FWL), defined as distance from base to apex (including fringe), was measured to the nearest one tenth of a millimeter. A rough indication of forewing geometry is provided by the aspect ratio (AR), defined as FWL divided by medial forewing width, the later measurement taken perpendicular to the dorsal margin. Costal fold ratio (CFR) is defined as costal fold length divided by FWL. Reported values of AR and CFR are averages, rounded to two decimal places, of the corresponding values calculated for a small sample of specimens. The number of measurements or observations supporting a particular statement is indicated by n. Forewing pattern terminology follows Brown & Powell (1991) and Baixeras (2002).

Eucosma rusticana is identified by the following forewing characteristics: dorsal surface (Fig. 2) divided longitudinally into a blackish-brown anterior region and a brownish-tan dorsoterminal region, the line of separation running roughly along the cubital vein from base to ocellus ee fron, there obliquely outward to costa just short of apex: region between said line and dorsal margin crossed longitudinally by three or four brown streaks; ocellus with pale-tan central field, bordered basally and distally by indistinct, transverse, silvery-gray bars and crossed longitudinally by two, variably expressed, dark-brown dashes: ninth costal strigula white and conspicuous, other costal strigulae gray and obscure. In melanic specimens the anterior region of the forewing is nearly all black, with black suffusion extending to dorsum, but the streaked appearance of the dorsal region is still apparent. Forewing statistics: 6 FWL 9-12 mm (mean = 10.3, n = 25), AR = 2.57, CFR = 0.47,2 FWL 9.9-12.2 mm (mean = 11.2,n =5), AR = 2.43. Male genitalia (Fig. 4) (n = 2): Uncus convex and moderately developed, socii long and setose, dorsolateral shoulders of tegumen well developed, gnathos a narrow band; vesica with ca. 22 deciduous cornuti, valva with dorsal margin strongly concave, apex rounded, SOCIETY JOURNAL OF THE LEPIDOPTERISTS’ Fics 1-4: Adults and male genitalia. 1, haydenae, holotype. 2, rusticana, Rowan Co., Kentucky. 3, haydenae, Howard Co., Iowa, slide DJW 556. 4, rusticana, Wy. andot Co., Ohio, slide DJW 167.

Biology and distribution. I examined 52 specimens (46 ¢, 6°) from Arkansas, Illinois, Indiana, Kentucky, Missouri, Mississippi, North Carolina, Ohio, Tennessee, Texas and Wisconsin. The flight period extends from mid April to mid August, the earliest records coming from Mississippi. Midwest records are predominantly from June and July. No larval host has been reported, but other members of the genus are known to be stem and root borers of Asteraceae. Eucosma haydenae new species (Figs. 1, 3, 5, 6) Diagnosis. Size and forewing maculation distinguish haydenae from other eastern North American species of Eucosma. Mean FWL of superficially similar rusticana is ca. 3 mm longer than that of haydenae. Distinctive male genitalic characters include the scooped out invagination of the medioventral surface of the valval neck and the rounded anteroventral projections of the anellus. The sclerotized twist in the female ductus bursae is prominent but not unique to this species. Description. Head: Lower frons creamy white, upper frons creamy white to light brown, vertex brown, scales adjacent to eye lighter; labial palpus with basal segment white, second segment with medial surface and dorsal margin white, lateral surface gray brown with white medial mark, third segment brown, often with blackish- brown apex; antenna with dorsal surface brown, posterior surface white.

Etymology. Dr. Ada Hayden (1884-1950) was a botanist at Iowa State College (now Iowa State University) who devoted much of her professional life to the study of the native Iowa prairie (Isely, 1989). Her advocacy in the 1940's for conservation of prairie habitat was largely responsible for the preservation of the 240 acre tract in northeast Iowa that now bears her name and serves as the type locality for the moth described here. It's a pleasure to name this insect after Dr. Hayden. Distribution and biology.

NYMPHALIDAE) MIGRATION, NECTAR RESOURCES AND FIRE REGIMES IN THE OUACHITA MOUNTAINS OF ARKANSAS D. CratG RUDOLPH, CHARLES A. ELy, RICHARD R. SCHAEFER, J. HOWARD WILLIAMSON, AND RONALD E. THILL Wildlife Habitat and Silviculture Laboratory (maintained in cooperation with the Arthur Temple College of Forestry, Stephen F. Austin State University), Souther Research Station, USDA Forest Service, 506 Hayter Street, Nacogdoches, Texas 75965 USA Email: crudolph01@fs.fed.us ABSTRACT. Monarchs (Danaus plexippus) pass through the Ouachita Mountains in large numbers in September and October on their annual migration to overwintering sites in the Transv olcanic Belt of central Mexico. Monarchs are dependent on nectar resources to fuel their migratory movements. In the Ouachita Mountains of west-central Arkansas migrating monarchs obtain nectar from a variety of plant species. especially Bidens aristosa and other composites. Fire suppression has greatly alteredit the structure of forest communities with major implica- tions for ecological relationships. Sites that are undergoing restoration to a shortleaf pine-bluestem grass community following thinning and fre- quent prescribed fire, and thought to closely resemble. pre-European conditions, support ineroneed abundances of nectar resources and migrating monarchs compared to mintreated controls. These results suggest that widespread fire-suppression since the early 1900s has substan- tially reduced nectar production for migrating monarchs in the Ouachita Mountains Physiographic Region. Additional key words: Interior Highlands, surveys, restoration The eastern North American population of the monarch butterfly, Danaus plexippus L., undertakes one of the most remarkable migrations of any lepidopteran (Urquhart 1976, Brower & Malcolm 1991). During the fall most individuals of this population migrate to extremely restricted sites in the Transvolcanic Belt of central Mexico (Urquhart 1976, Calvert & Brower 1986). Concern has been expressed about the continued health of this population and the persistence of the massive migration phenomenon (Wells et al. 1983, Brower & Malcolm 1991). Changes in abundance and quality of larval hosts (Zalucki & Brower 1992), loss of critical overwintering sites due to logging and fire (Brower 1996, Brower et al. 2002), vehicle mortality (McKenna et al. 2001), pesticides (Oberhauser 2004), introduced species (Calvert 2004), and transgenic Bt modified crops (Losey et al. 1999, Jesse and Obrycki 2004) have been identified as actual or potential threats. Less attention has been directed to landscape-level changes in nectar availability which ultimately fuels the extended fall migration to central Mexico (Garcia & Equihau-Zamora 1997, Brower & Pyle 2004). Land use changes and management protocols in more natural habitats have dr: eeeally altered essentially all the land base that constitutes the breeding range and migration corridors of D. plexippus in eastern North America. The Ouachita Mountains Physiographic Region of west-central Arkansas and southeastern Oklahoma, encompassing 3,237,600 ha, remains primarily forested (Bukenhofer and Hedrick 1997). However, logging, fire suppression, and silvicultural management have altered vegetation structure and composition throughout the region (Foti and Glenn 1991, Masters et al. 1995). Fire-maintained shortleaf pine (Pinus echinata) forests were widespread in the Ouachita Mountains until the early 20th century (Foti & Glenn 1991). Since the original harvest of these pine forests, most forested sites have been altered using intensive short-rotation pine production or remain as more natural forests, but have been subjected to fire suppression for several decades (Bukenhofer and Hedrick 1997). In either case, the abundance and quality of nectar resources available to Lepidoptera has been drastically altered (Thill et al. 2004). The managers of the Ouachita National Forest have initiated a landscape scale restoration of the fire- maintained shortleaf pine-bluestem (Schizachrium spp.. Andropogon spp.) ecosystem on 48,706 ha (U. S. Forest Service 1996). Restoration involves thinning the overstory, reduction of midstory vegetation, and prescribed burning on a three-year return interval. This restoration was undertaken to restore habitat for the endangered red-cockaded woodpecker (Picoides borealis) and to restore what is thought to be the pre- European structure and composition of the vegetation (Foti and Glenn 1991, Bukenhofer and Hedrick 1997). A number of authors have examined the effect of these restoration efforts on a diversity of taxa (see Thill e¢ al. 2004). As part of ongoing studies of the effects of restoration of fire-maintained shortleaf pine-bluestem habitat on lepidopteran communities, butterfly and nectar resource surveys were conducted in restored and untreated control plots. This paper reports results for D. plexippus in relation to the fire regime and suggests implications for fall migration and over-winter survival. MATERIALS AND METHODS This study was conducted on the Poteau Ranger District (34°45'N, 34°15'W) of the Ouachita National 166 Forest in west-central Arkansas. Topography in this region consists of east-west trending ridges and valleys of 150-820 m. Mixed hardwood forests dominate north-facing slopes and pine and mixed pine-hardwood forests dominate south- with an elevational range facing slopes. Prior to the initiation of fire-suppression activities, much of the landscape, especially the more xeric pine communities on south- and west- facing slopes, burned on a regular basis (Foti and Glenn 1991, Masters et al. 1995). These were primarily low intensity ground fires ignited by lightning, Native Americans, and more recently by European colonists. The resulting forest structure was characterized by pine- -dominated overstories, sparse midstories, and diverse herbaceous understories (du Pratz 1975, Featherstonhaugh 1844, Nuttall 1980, Foti and Glenn 1991). The Ouachita Mountains are still predominately forested; however, logging and fire-suppression have dramatically altered vegetation structure (Bukenhofer and Hedrick 1997). conditions, existing forests are typically characterized by Comps ured to pre-European a younger and denser canopy, a dense woody midstory, anda very suppressed herbaceous understory (F enwood et al. 1984, Masters 1991, Sparks 1996). These changes have profoundly altered the original biodiversity of the Ouachita Mountains (Neal and Montague 1991, Smith and Neal 1991, Wilson et al. 1995, Sparks et al. 1998, Thill et al. 2004). Landscape scale restoration was initiated in 1979, formally incorporated into the Ouachita National Forest Plan in 1996, and currently projects the restoration of 48,706 ha (7.3% of the Forest) to a shortleaf pine- bluestem condition (U. S. Forest 1996, Bukenhofer and Hedrick 1997). Restoration consists of thinning of the Service overstory, removal of most midstory vegetation, and prescribed burning on approximately a 3-year rotation (U.S. Forest Service 1996). Ultimately, regeneration of canopy trees will be accomplished primarily through _ the implementation of irregular shelterwood and seed-tree harvests with a portion of the overstory retained indefinitely (U. S. Forest Service 1996). In addition, rotation age will be lengthened, primarily to provide sufficient older trees to support red-cockaded woodpecker recovery (Rudolph and Conner 1991). A the initiation of our studies, approximately 9,071 ha had been restored in a 42,148 ha landscape on the Poteau Ranger District (W. G. Montague pers. com.). We use “restored” in a relative sense and recognize that stands are on a trajectory toward an ecological state that resembles pre-European conditions. Je JURNAL OF THE LEPIDOPTERISTS’ SOCIETY MATERIALS AND METHODS We censused butterflies and nectar annually in resources and three from 10.5 to All treated sites had received a minimum of \ nine restored (treatment) sites un-restored (control) sites.

Adult butterflies (only D. plexippus data reported here) were censused using a time-constrained walking along 500-m triangular transects centrally located within each site (Pollard 1977, Pollard and Yates 1993). Individual transects were censused by slowly walking the length of transects for approximately 20 Time involved in counting butterfly aggregations, netting individuals for identification, or waiting for sun or wind conditions to conform to set variables was not included in the 20-min period.

Census counts were replicated three times each month, represented by three _ sites. census min. each replicate conducted by a different observer on different days during the survey week. Individual censuses were conducted between 0900 and 1330 hrs CST when temperatures were between 18—36° C and wind velocity beneath the canopy was not too high to suppress butterfly flight (Beaufort Scale <4). Censusing was further restr jcted to periods when sunlight was sufficient to cast discernable shadows.

Consequently, observer judgement further constrained varies censusing to those periods when butterfly activity appeared to be substantial. Additional details concerning treatment and control sites can be found in Thill et al. (2004). In addition to census counts of butterflies, we recorded all observations of nectaring and other feeding activities by butterflies observed during this and other studies in the Ouachita Mountains hemveen 1999 and 2004. Voucher specimens were deposited in the herbarium of Stephen F. Austin State University. Plant nomenclature uses the nomenclature found in Smith (1994). Nectar resources were quantified by counting flowers VOLUME 60, NUMBER 3 in three 1x100-m plots at each study site. Plots were located parallel to each side of the triangular 500-m butterfly census transect. Within these plots all potential nectar resources were counted each week that butterfly censuses were conducted. For most plant species, individual flowers or composite heads (capitula) were enumerated. Inflorescences, or portions thereof, were counted for a few species with small and/or dense aggregations of flowers (e.g. Ceanothus americanus, Allium spp., Solidago spp., Apiaceae). These enumeration decisions were based on estimating the structure that most closely approximated a separate landing site for a typical butterfly. TaBLE 1.

However, during the fall migration in September and October, D. plexippus were common to abundant. We obtained a total of 2701 D. plexippus nectaring observations from 1999 to 2004. All but 101 of these observations were made during September and October (Table 1). Danaus plexippus nectared most frequently on Bidens aristosa (1890, 70.0%), Solidago spp. (180, 7.0%), Eupatorium serotinum (164, 6.1%), Aster spp. (98, 167 3.6%), Vernonia baldwinii (93, 3.4%), Cunila origanoides (69, 2.6%), Liatris spp. (59, 2.2%), and occasionally on an additional 31 species. The 1890 nectaring observations on Bidens aristosa were during the fall migration, and were concentrated primarily on the verges of the extensive road system within the region. Due to low regional abundance we counted only 15 D. plexippus during April, June, and August censuses. During October, generally the peak of migration, a total of 1019 D. plexippus were detected during transect surveys. These observations occurred most often on restored treatments, especially during the first growing season post-fire, rather than on controls (Table 2). Significant differences were detected across treatments (x2 = 1637.6, df = 3, P < 0.001). Nectar resources were also more abundant on restored treatments than on controls (Table 3). Within restored treatments, nectar resources were more abundant on first year post-burn treatments and least abundant in third year post-burn treatments during the October surveys. Significant differences were frequently detected across these four treatments (Table 3). TABLE 2.

DISCUSSION Restored sites in the Ouachita Mountains consisting of a fire-maintained shortleaf pine-bluestem community supported a higher abundance of D. plexippus during migration than un-restored, fire-suppressed controls. This pattern was most noticeable during the first October post-fire. Both aspects of this pattern were similar to the abundance of nectar sources. Numbers of D. plexippus detected varied considerably across years. This may have been due to timing of the migration relative to our survey times, or changes in D. plexippus numbers in the eastern North American 168 TABLE 3.

The very low numbers in 2002 followed of flowers located in disturbed sites, mainly the catastrophic winter storm mortality at the Mexican over- wintering sites the previous January (Brower et al. 2004). In the absence of frequent fire, nectar resources in the forested portions of the Ouachita Mountains Physiographic Region are generally low. Improved pastures and intensively managed pine plantations 2-3 years after planting, the only other significant land uses in the region, also typically support a low abundance of nectar resources. Limited areas of increased nectar abundance occur in disturbed sites, i.e. road verges, utility rights-of-way, fence rows, and areas of recent timber harvest. primarily forested area, nectar resources may be Thus, at the regional level, in this limiting for lepidopteran species that require them (Thill et al. 2004, Rudolph e¢ al. In prep.). Similar results were found for fire-maintained pine communities in eastern Texas (Rudolph and Ely 2000). Due to the very patchy distribution of nectar sources in relation to roads, rights-of-way, and forest management we were unable to assess the relative abundance of nectar landscape. The relative numbers of nectaring observations in Table 1 are probably biased toward those occurring along road_ verges. However, butterflies, including D. plexippus, were frequently observed nectaring along the transect surveys, especially in the restored treatments. Data presented here indicate that fire suppression has resulted in a landscape that is currently depauperate in nectar availability. We suggest that reduced nectar availability, compared to probable pre-European conditions, limits use of the widespread fire-suppressed habitats by monarchs and other lepidopteran species (Thill et al. 2004). The large numbers of monarchs passing through the Ouachita Mountains each fall obtain nectar resources primarily from concentrations sources across the entire abundant Bidens aristosa growing on road verges. How this current availability of nectar resources compares with the pattern of nectar resources dispersed across the forest landscape in the pre-European fire-maintained shortleaf pine forests is unknown, but this pattern suggests that fire suppression has greatly limited the availability of nectar resources across most of the forested landscape. Lipid-loading by D. plexippus during the fall migration, both to fuel the migration and sustain winter survival, is crucial (Brower 1985, Alonso- Mejia et al. 1997). Brower and Pyle (2004) suggest that lack of nectar resources might bea limiting eiaon for migrating D. plexippus. In addition, a significant proportion of the monarchs inhabiting the wintering sites in the Transvolcanic Belt lack sufficient lipids to survive until spring (Brower & Pyle 2004). A detailed understanding of the current quality and availability of nectar resources along the migration corridor, and effects of historical changes, mould allow an improved understanding of the remarkable migration of D. plexippus. Our results suggest that historical changes have been substantial, even in a landscape still dominated by “natural” plant communities. These changes may have potential consequences for migrating monarchs. Habitat and critical ecological processes, fire in this instance, may both be important in maintaining a major biological phenomenon on a continental scale. ACKNOWLEDGMENTS We thank R.

A highly migratory species, K. lyside often travels en masse within and between the islands of the Caribbean Fic 1. Kricogonia lyside on Vaca Key, Credit: H. L. Salvato). 23 July 2005 (Photo (Wolcott 1927, Williams 1930, Smith et al. 1994, Miyata 2000). The species also demonstrates similar mass movements in the southwestern United States with large influxes entering southern Texas from Mexico (Clench 1965, Gilbert 1985). Dispersal of K. lyside into and within southern Texas appears to be triggered by reductions in new hostplant growth (Gilbert 1985). However, whether or not similar ecological cues encourage K. lyside migrations, both within the Caribbean and to southern Florida, remains unknown. Luis R. Hernandez (pers. comm.) suggests tropical storm activity in the Caribbean may play a large role in the dispersal of K. lyside within the West Indies, and perhaps to southern Florida. Smith et. al. (1994) witnessed several K. lyside making landfall on Upper Matecumbe Key via strong, although not storm-related, easterly winds, indicating the species is capable of dispersal into the Keys during typical seasonal conditions. Young (1938), based on examination of fresh specimens collected near Biscayne Bay, suggested that the species reproduces within Souther Florida and the Keys. However, neither oviposition nor larval activity has ever been observed for K. lyside in the region. A known hostplant of this species, lignum vitae, Guaiacum sanctum L., (Zygophyllaceae) occurs commonly within hardwood hammocks throughout the Keys and is also widely used in the region as an or namental species in landscaping. Following an apparent decade-long absence in Florida K. lyside was observed locally from June through September 2002 on Plantation Key (Salvato and Salvato 2002) and Key West (MHS unpublished data) in the Florida Keys. After these initial observations of K. lyside re-occurrence in the Keys MHS and HLS continued to survey for this species as part of a larger ongoing long-term study to determine the status and distribution of butterflies throughout the Keys. Surveys were conducted on warm, clear days under conditions that were considered sufficient for butterflies to be flying. Each sampling date included approximately S-9 hours of field time (between 0800-1700 h) in which two surveyors (MHS and HLS) walked a standard route at survey sites within the study area to visually record K. lyside activity. On each sampling date a selected span of the Keys was monitored in either the Upper (Key Largo to Upper Matecumbe Key), Middle (Lower Matecumbe Key to Vaca Key) or Lower Keys (Bahia Honda Key to Key West). Survey sites on each island were visited monthly during May 2002 to December 2005, with the exception of Lignumvitae Key, which due to its inaccessibility, was only surveyed during June of each survey year. The amount of time spent surveying for K. lyside on each Key varied based on island size and number of survey sites. Overall, a total of 25 survey sites, of varying sizes, were monitored monthly during this study. These locations included State and County parks, National Wildlife Refuges and roadsides. Guaiacum sanctum was observed either directly within or adjacent to the majority of our study areas. Although there were unconfirmed reports of K. lyside during ¢ 2003, we did not observe the species again in the Keys until 13 June 2004, after which K. lyside was frequently encountered throughout the Florida Keys, as well as southern Miami- Dade County, marking the first known occurrences for the species on mainland Florida in several years. Kricogonia lyside was absent from the majority of the islands we surv eyed by mid-August 2004; however, local occurrences remained on Bahia Honda within the lower Keys into November of that year. In 2005, we began to re-encounter K. lyside during the early summer months with our first observations occurring on Lignumvitae Key on 11 June. Despite an abundance of G. sanctum on Lignumvitae Key, K. lyside had never been reported from this island (Minno and Emmel 1993, Smith et al. 1994). To our knowledge these observations of K. lyside on Lignumvitae Key represent the first reports from this island. From June through August of 2005 K. lyside was observed on every island we surveyed within the Keys (Fig. 2). Throughout this time frame the species was witnessed actively dispersing towards the east on both the northern and southern coastlines of the Keys, as well as on outer islands such as Lignumvitae Key, indicating a wider migratory swath than was noted earlier in either the 2002 or 2004 observations. As was observed in JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY 2004, K. lyside remained on Bahia Honda until later in the season (at least through 24 September 2005) than elsewhere in the Keys. Table 1 provides an overview of K. lyside observations made on various islands within the Florida Keys during this survey. As with Lignumvitae Key, several of the K. lyside observations listed in Table 1 appear to be the first documented occurrences of the species on select islands, particularly within the Lower Keys (Minno and Emmel 1993). We observed an estimated 10, 74 and 238 individuals of K. lyside during monthly surveys of the Keys in 2002, 2004 and 2005, respectiv ely. In all years the majority of individuals were found on Key West, Bahia Honda, Vaca Key and Plantation Key with varying numbers of individuals occurring on 15 other islands in the Keys. Although the sexes are similar, males from western Cuba and the Bahamas are distinctive from other known K. lyside populations in that these individuals generally lack a black bar near the apex of the upper hindwing (Riley 1975, Minno and Emmel 1993, Hemandez 2004, J. Y. Miller, pers. comm.).

During June to mid-August of 2004 and 2005 Kricogonia lyside was consistently observed in active fren! traveling in either an easterly or northeasterly direction between islands in search of, and in frequent interaction with, G. sanctum. Conversely, K. lyside observed later in the season during 2004 and 2005, specifically those remaining on Bahia Honda, occurred only locally and took nectar from any available sources, not just those in the immediate proximity of the hostplant. Despite extensive searches throughout the study period for signs that K. lyside had reproduced or underwent diapause in southern Florida it was not until 9 July 2006 that MHS, HLS and Dennis J. Olle observed the species mating and ovipositing on the fruit and fresh growth of G. sanctum on Stock Island and Key West. Additionally on Key West, K. lyside was observed actively ovipositing on the leaves of Maracaibo lignum vitae, Bulnesia arborea ( (Jacq.)Engl., (Zygophyllaceae) a 173 non-native species that occurs as an ornamental in the Keys and was not common in our study areas. To our knowledge these observations of oviposition provided the first accounts of K. lyside reproduction in southern Florida. However, K. lyside larval activity was not observed during these studies. Larvae of K. lt lyside feed nocturnally (Riley 1975, Hernandez 2004) and early instars are similar in coloration to that of the new G. sanctum growth on which they feed (Allen et al. 2005). The mature larvae are darker green with white and brown stripes (Minno et al. 2005). The cryptic coloration and nocturnal feeding habits of K. lyside larvae makes the species difficult to find on the hostplant (Luis R. Hernandez, pers. comm.) and may explain our inability to locate them. Additional studies are needed to better determine the occurrence and natural history of immature K. lyside in southern Florida. Furthermore, there were no signs of adult K lyside activity across the Keys by mid-fall of 2002, 2004 and 2005, suggesting the species may disappear from Florida and then sporadically re- -colonize, probably from Cuba. The tropical storm seasons in 2004 and, for the Keys particularly 2005, were extremely active. However, the influxes and northeastern movements of K. lyside across the Keys and into southeastern Florida preceded any significant storms occurring during these study years. Our observations indicate that K h yside periodically disperses to a greater array of islands in the Florida Keys than previously noted. We have documented that during some years large numbers of K. lyside adults occur in the Keys. Additionally, K. lyside appears to breed in southern Florida, but to what extent the species colonizes within the state requires further investigation. The authors thank Luis R. Hermandez for sharing his field ob- servations and insights on the biology of K. lyside in the West In- dies. Jacqueline Y.

A PRECAUTIONARY TALE ABOUT RARITY: ON THE LARVA AND LIFE HISTORY OF LITHOPHANE JOANNIS (LEPIDOPTERA: NOCTUIDAE) Additional key words: shelter-forming, Aesculus flava, Lithophane innominata, Lithophane patefacta This note is about rarity, and how species that are regarded as scarce may be anything but, once aspects of their life history are better understood. Lithophane joannis Covell and Metzler was not described until 1992. Prior to the authors' distribution of paratypes there were no specimens of L. joannis in any major eastern institution, i.e., the Smithsonian, American Museum, and Carnegie Museum. Not William Forbes; nor Jack Franclemont, Doug Ferguson, Michael Pogue, Eric Quinter, or Tim McCabe has collected the moth. Dale Schweitzer wrote his dissertation on the tribe—he has yet to see the moth alive. Despite year-round surveys in Great Smoky Mountains National Park (GSMNP)—and especially over the last five years during which time the Park has been the focus of intensive surveys as part of its “All Taxon Biodiversity Inventory —the moth escaped detection. Yet Lithophane joannis is among the Park's most common lepidopterans in middle elevation cove forests. On 19 May 2001 I collected two Lithophane larvae crawling up the trunk of a small yellow buckeye tree (Aesculus flava Ait.) (Hippocastanaceae) while collecting moths at a sheet and mercury light (with Doug Ferguson), above the Chimneys Campground (1000m) in Great Smoky Mountains National Park, Sevier County, Tennessee. The caterpillars looked similar to those of the innominata group (e.g., L. hemina Grote, L. patefacta (Walker), L. petulca Grote and L. innominata (Small), and others), but different enough to raise doubt. Based on the host association and phenotype, Dale Schweitzer guessed that the larvae were those of Lithophane joannis. Return trips to the same pullout along Newfound Gap Road in 2002, 2003, and 2004, yielded additional examples of the Lithophane. Typically, only one or two caterpillars were collected each year. Unfortunately, I failed repeatedly to rear examples through to the adult stage- inappropriate foliage was offered or larvae were lost during the obligatory, four-month prepupal diapause common to Lithophane and other xylenines. In 2005, while light trapping at the same site above the Chimneys Picnic area, I thoroughly searched the same 4m yellow buckeye tree that had yielded caterpillars in every year previous. Nine Lithophane caterpillars were found in 20 minutes of searching (by flashlight). The larvae were feeding, perched on He underside of leaves, or observed walking along the trunk, with the exception of two larvae that were recovered from within leaf shelters. Both of these latter individuals were in the process of molting. Returning to the same area two days later (20 May, 2005), I happened upon a buckeye tree with numerous leaf shelters. Upon opening the first, I found a last instar Lithophane. Searching this same tree I counted more than 20 additional Lithophane joannis caterpillars in less than 10 minutes by opening other leaf shelters. Nearly every shelter had a caterpillar and some two (few if any of these were in the process of a molt). No additional VOLUME 60, NUMBER 3 caterpillars were obtained by beating limbs of the same tree over a large queen- sized bed sheet. In late September, a series of Lithophane joannis issued from this collection (Fig. 1). The larva of Lithophane joannis is strongly mottled (Fig. 2). There is often a straw to yellow tint where adlnoca segments overlap and/or a tan to straw flush to the middorsal and lateral stripes. The white dorsal pinacula (D1 and D2 setae) are edged with black; both dorsal pinacula are often embedded in a diffuse dark patch that is best developed over the eighth abdominal segment. The well-differentiated prothoracic shield is heavily blackened above the subdorsal stripe. Below the lateral stripe the subventer and venter are pale a largely unmarked. The head bears a dark coronal bar, a black spot within the frons (frontal triangle), and a black bar above each antenna. Fully mature last instars are about 4 cm in length. The middle and penultimate instars are lime green, translucent, with a strong, somewhat creamy spiracular stripe and a broken, w hite middorsal stripe; the body bears numerous minute white spots over the trunk (Fig. 3). In appearance the last instars those of L. hemina and L. innominata and may not be separable from them, although most individuals will be rec sognizable by their pale g arid color, especially those individuals that have a pale green, yellowish, or steely blue cast. In most instances, larvae of L. joannis will be identifiable by their host association (with buckeye). No other eastern Lithophane is known to consistently resemble take up residence in leaf shelters. Other members of the innominata complex typically rest in bark crevices by day (Wagner 2005) Trunks of Aesculus flava— particularly on the understory trees where one can expect to find larvae in numbers—are often smooth and without fissures in larvae could conceal It is not clear if L. joannis ever spins its own shelters or only uses those of other leps. In May which themselves. 2006 a collection of 13 additional larvae was made from the Chimneys area of the Park—all came from leaf shelters of microlepidopterans. Eight were collected from abandoned and pupal shelters made by Choristoneura fractivittana (Clemens) (Tortricidae) and the remainder from prepupal and pupal shelters spun by Yponomeuta multipunctella Clemens! (¥: ponomeutidae). Several Lithophane are known to be both predatory and cannibalistic, including the apparently closely- related L. patefacta (Schweitzer 1979; Wagner, 2005). While there would seem to be clear advantages to ‘While Yponomeuta multipunctella larvae normally feed on Euonymus, since 2004 I have increasingly noted larvae on other hosts in the Smokies.

And as noted above, I occasionally found shelters with two larvae. Similarly, 10 of 13 larvae collected in 2006 came from microlepidopteran — shelters above)—no evidence of predation was noted in these occupied (see (or any of the other shelters opened on the day of the initial collection in the Park). In the middle elevation cove forests of GSMNP caterpillars of Lithophane discovered, the insect is among the most abundant where joannis were noctuid caterpillars—on 20 May, 2005, L. joannis was arguably the most common noctuid caterpillar present in the C himneys area. At the type locality in Ohio, L. joannis outnumbered all other members of the genus Lithophane at bait (Covell and Metzler 1992). Interestingly, adults ignored the light traps that were run at the same location (Eric Metzler pers. comm.). L. joannis provides a noteworthy case of apparent rarity— 176 if one were to depend on standard light trapping methods one would conclude that the moth is among the rarest lepidopterans in eastern North America. However if one employs bait or searches for caterpillars one could conclude just the opposite, that L. joannis is among the most common noctuids in Appalachian forests where its foodplant, Aesculus flava, grows in abundance. Identification of the adults was confirmed by Eric Metzler. Vouchers of both larvae and adults have been deposited at the University of Connecticut; adults have also been deposited at the United States National Museum. James Adams, Dale Schweitzer, and Bo Sullivan offered suggestions on an earlier draft of the paper and Rene Twarkins assisted with the larval images.

The larger of the two populations occurs inside National Guard Training Center-Fort Indiantown Gap (NGTC-FIG), an approximately 6,925-ha military base located in south- central Pennsylvania. Comprehensive descriptions of the old-field successional habitats occupied by S. idalia at NGTC-FIG are presented in Barton (1996) and TNC (2001). Morphologic and genetic evidence indicates that eastern populations may deserve specific or subspecific status and designation as an evolutionary significant unit (Williams 2001a, 2001b, 2002). In light of the conservation status of S. idalia, research is warranted on its life history. Nocturnal foraging on Viola species has been reported or referenced for S. idalia larvae by Holland (1898), Ferris & Brown (1981), Opler & Krizek (1984), Schull (1987), Royer (1988), Iftner et al. (1992), Royer & Marrone (1992), and West (1998). However, Kopper et al. (2001) documented diurmal feeding on V. pedatifida G. Don (Violaceae) in three out of 12 S. idalia larvae observed in Kansas. At NGTC-FIG, Barton (1995) reported diurnal movements of S. idalia larvae and noted the predominance of V. sagittata Aiton relative to the presence of other Viola species but did not describe larval foraging behavior. Because S. idalia larvae have been challenging to locate in the field across the species' range (Scudder 1889 for New England, TNC 2001 for Pennsylvania, Kopper et al. 2001 for Kansas, Debinski pers. com. for Iowa), behavioral observations of larvae have been difficult to obtain (Kopper et al. 2001). A combination of factors such as low population density (Barton 1995), small body size, solitary distribution, cryptic coloration and behavior (Stamp & Wilkens 1993), high mortality rates (Mattoon et al. 1971, Wagner et al. 1997), and concealing vegetation may par tially explain the modest numbers of field-documented larvae. Previous surveys conducted at NGTC-FIG to detect larvae have resulted in very small sample sizes (n = 9; Barton 1995) or failure (n = 0; TNC 2000, 2001). On May 14, 2001, one S. idalia larva unintentionally discovered at the Pennsylvania site during a vegetation study. Shortly thereafter, a qualitative survey of selected er asslands, known to be inhabited by S. idalia adults alanine previous years, was performed in an attempt to detect more larvae. Typically conducted between 0900 and 1600 hrs, the survey followed a generalized protocol: searching for individuals and groups of V. sagittata (including arrow- and ovate-leaved varieties), inspecting violets for evidence of strip-feeding herbivory (typical of S. idalia), and visually scanning violets and the surrounding area for larvae. Images of S. idalia larvae in Allen (199 7) and Richard & Heitzman (1987) assisted with positive species identification. Was VOLUME 60, NUMBER 3 177 TABLE 1.

Digital photographs were taken of each larva encountered and of the habitat in the immediate vicinity of each sighting. Spatial coordinates of larvae were determined through Global Positioning System (GPS) technology (hardware: Pro XR Trimble receiver unit and TSC1 Asset Surveyor Trimble datalogger; software: Pathfinder Office version 2.80) and expres in Universal Transverse Mercator (UTM) meters. Larvae were not marked so as to avoid potential handling effects. Because newly and_ previously identified larvae were indistinguishable, duplication was possible but unlikely, due to the relatively long distances between sightings on preceding days [i.e., ~80 (minimum), ~7000 m (maximum)]|. The two larvae observed simultaneously on May 18 were separated by Fic. 1. Images of two S. idalia larvae diumally foraging on V. sagittata in the field (a) Pennsylvania, May 2001. approximately two meters. Diurnal foraging on V. sagittata was documented in five of the six larvae observed (Table 1 and Figure 1), a strong trend despite the extremely small sample size. Similar to those reported in Kopper et al. (2001), feeding bouts were short-lived. S. idalia larvae were Tied to consume only leaves of V. sagittata, either partially or completely. In addition to foliar herbiv ory, Beattie & Lyons (1975) and Kopper et al. (2001) reported floral consumption of Viola spp. by the larvae of Argynnis spp. and S. idalia, respectively. Such behaviors, as well as nocturnal foraging bouts, may have been exhibited by larvae at the NGTC-FIG site but were not observed. Nonetheless, given the observations presented here for Pennsylvania, in conjunction with those for Kansas by Kopper et al. (2001), diurmal foraging by S. idalia larvae may be more prevalent than atari and in controlled conditions (b) at NGTC-FIG, 178 previously described in the scientific literature. Drs. Brian Kopper and Barry Williams (University of Wis- consin), Dr. Roger Latham (Continental Conservation), and Joseph Hovis (Pennsylvania Department of Military and Veter- ans Affairs or DMVA) offered insightful comments on a preced- ing draft.

Book REVIEW Journal of the Lepidopterists’ Society 60(2), 2006, 179-180 THE GEOMETRID MOTHS OF EUROPE (A Hausmann, ed.), Volume 2. Sterrhinae. Axel Hausmann. 2004. Apollo Books, Stenstrup, Denmark. 600pp. Hardback ISBN 87-88757-37-4. Priced at 140 Euros on http:/Avww.pensoft.net/notes/12090.stm. This volume represents another _ significant contribution to a series on European Geometridae that will be seen in retrospect as perhaps the most significant milestone in our understanding of that fauna. Not only does it provide a comprehensive review of our knowledge to date, coupled to an immense amount of fresh research based on exhaustive examination of copious material, but it probably comes at a turning point in the way taxonomic information is presented, with the emphasis moving more towards the electronic media, away from print on paper. The editorial preface indicates the w ay the volume is embedded within the context of existing or imminent initiatives in electronic informatics for Geometridae. But, as someone who sometimes wonders whether the rush to embrace the electronic age may be more headlong than judicious, given our lack of experience of the security/vulnerability of the internet to all sorts of factors, I am reassured to know that there are hard-copy products such as this to fall back on under any worst case scenario. The Sterrhinae, after the Larentiinae, are probably the most successful subfamily of the Geometridae in their proportional representation at temperate latitudes, though the Ennominae may have higher numerical representation. They also contain, after Ewpithecia in the Larentiinae (covered in Vol 4 of this series), the two next most species-rich geometrid genera: Scopula and Idaea. All three genera pose emcee difficulties in identification of their species, so publication of these two volumes has removed this impediment for the European fauna. The preface notes the strong (particularly western) Mediterranean focus of the subfamily in a European context, relative to the more even distribution of the Larentiinae, but this aspect is not explored to any great extent in the main text, though all the data are there to enable interested readers to analyse it for themselves. For example, there is endemism at a generic level, albeit from genera that are monotypic such as Anthometra (eastern Mediterranean) and Emmiltis (central Mediterranean), or Oar, if regarded as distinct from Scopula, with just two species in the Mediterranean. The five species of Cleta are also essentially Mediterranean, and also the genus Glossostrophia. Brachyglossina includes major N. African and Levantine species groups, with one species in Spain considered to be an outlier of the latter group. Apart from these smaller genera, the Mediterranean focus is seen to an extreme in Idaea, where over two- thirds of the species are Mediterranean, 73% of these restricted to the western part. In Scopula, as in the larentiine Eupithecia, only one third are Mediterranean, and those are more evenly distributed across that region. The book reviews extensively the recent taxonomic advances made for the subfamily, but there is still not a full consensus on the generic classification, as indicated by Sihvonen (2005, Nota lepid., 28: 70-71) in his review. There is also discussion of relationships of the Sterrhinae within the family as a whole, where there is growing consensus that the Sterrhinae and Larentiinae are the most basal groups, though relationships between the two lineages of Sterrhinae and the Larentiinae still need further study. All species are copiously illustrated by color plates showing the range of variation, often accompanied by diagnostic half-tone figures in the body of the text. There are clear line-drawings of male and female genitalia, and some stereoscans of critical features of antennae and legs. As with other volumes, the description of the adult is headed as a diagnosis, and the true diagnosis is found as an account of differences of similar species. The text for each species includes extensive reviews of available biological and ecological information, drawing on the breadth of literature and current expertise on the fauna. Most species have larvae that are herbaceous feeders, those of Idaea tending to prefer dried or withered foliage. However, the larvae of the genus Cyclophora are ar boreal defoliators. The systematic checklist at the end of the book also lists, with asterisks, species from neighboring areas, a particularly useful addition given the Mediterranean nature of the group, enabling the reader to appreciate how the diversity extends to N. Africa, Turkey or the Levant. Species from Madeira and the Canaries are also listed. The distributions of all species are illustrated by maps with shaded areas indicating the general range within which are placed black circles or other sy mbols indicating more precise localities from which material 180 JOURNAL OF THE LEPIDOPTERISTS’ SOCIETY has been examined.
