PSYCHE. 



[November, ig02 



Subfamily LIBYTHEINAE. 



Butterfly: Palpi of excessive length, 

 even exceeding that of the thorax (except 

 in some exotic forms), the fringe short. 

 Antennae clothed, gently arcuate, the 

 club gradual. Fore legs of $ atrophied, 

 of ? nearly normal but abbreviated. 

 None of the nervures of the fore wings 

 swollen at the base ; discal cell of hind 

 wings closed by a feeble vein. Generally 

 of a dark color with obliquely transverse 

 broad dashes or blotches of white or 

 orange. Egg'- Elliptic, much higher 

 than broad, more or less produced at 

 apex and truncate at base with high 

 vertical ribs, highest above. Caterpillar 

 at birth: Head much larger than the 

 segment following. Body cylindrical, mi- 

 nutely and briefly pilose. Maticre cater- 

 pillar : Head unarmed, no larger than 

 segments following. Body cylindrical, 

 slightly enlarged at the end of the tho- 

 racic segments, pilose, longitudinally 

 striped on the sides, the last segment 

 abruptly curved, not furcate. Feeds on 

 Urticaceae and so far as known only on 

 Celtis. Chrysalis : Ovate, compressed, 

 with no conspicuous prominences and 

 everywhere well rounded ; with no 

 transverse ridges ; abdomen mediodor- 

 sally carinate. Ventral surface nearly 

 straight. 



Contains but a single tribe, Libytheini. 



Subfamily LEMONIINAE. 



Butterfly: Labial palpi minute, only 

 the minute apical joint surpassing the 



face. Fore wings with a distinct inter- 

 nal nervure ; hind wings scarcely chan- 

 neled to receive the abdomen, furnished 

 with a precostal nervure, the costal 

 nervure running only to the middle of 

 the costal margin. Fore tarsi of male, 

 with rare exceptions, without spines or 

 claws. Generally (in our species always) 

 spotted or barred above. Egg : Foveolae 

 furnished with septae converging from 

 the walls toward the center. Caterpillar 

 at birth : Body with chitinous shields, 

 both dorsal and substigmatal, on every 

 segment, to which the piliferous papillae 

 are confined ; chitinous annuli only in 

 the subdorsal region. Mature catej-pillar: 

 Body scarcely onisciform though not 

 greatly elongated, the head relatively 

 large, being at least half as broad as the 

 middle of the body, and at most only 

 partially retractile within the succeeding 

 segment. Chrysalis : More or less elon- 

 gate and more or less angulate, the 

 abdomen more or less conical with pro- 

 tuberant cremaster, the body sparsely 

 clothed with long hairs. 



Only a single tribe, Lemoniini, occurs 

 within our district. 



Tribe Lemoniini. 



Butterfly : Hind wing provided with a 

 well developed basomarginal nervure. 

 Egg : Deeply reticulate and filamentous. 

 Caterpillar at birth : (Distinction from 

 other tribe unknown.) Mature caterpil- 

 lar : Clothed with longer or shorter hairs 

 or bristles of equal length in all parts of 

 the body and sometimes f asciated. Chry-
