102 LEPIDOPTERA HETEROCERA 
Only the single specimen is known. but it secms very probable that the venus is a rather 
specialized relative of Comibaena; the peculiar shape of the hindwing (strongly elongate to tornus) is 
distinctive, though there are other subordinate characters.

Characters. — lace smooth. Palpus with second joint usually rather long, more or less 
strongly rough-scaled above and beneath, third joint smooth, in c quite small to moderate, sometimes 
deflexed as in Comibaena, in Q long to very long (moderate in a few species only). Tongue present. 
Antenna moderate (rather long in some, at least, of the erixa- group), in cf bipectinate with short to 
moderate (in Section II longer) branches, apex nearlv simple; in Q nearly simple (in Section III shortly 
bipectinate). Pectus hairy. Femora glabrous 1). Hindtibia in cf nearly always dilated with hair-pencil, 
with rare exceptions also with well-developed terminal process. Abdomen not or scarcely. crested, but 
very often ornamented with discolorous spots, which (especially in Section II) are frequently somewhat 
embossed and occasionally somewhat erected posteriorlv as diminutive crests. Wing-scaling not very 
dense, but not translucent. Frenulum in cf not verv strongly developed, arising from before basal 
expansion, in Q consisting of a moderately strong tuft of hairs. Forewing with costa nearly straight or 
slightly arched, apex moderate to rather acute, termen straight or slightly curved, moderately oblique, 
tornus usually rather pronounced, cell less than one-half, DC curved, SC! from cell, free or anast- 
omosing with C, SC? normal (except in »/mo), scarcely ever anastomosing with SC!, R! short-stalked, 
connate or separate, M! connate or separate, rarely short-stalked; hindwing with costa not long, apex 
moderate, termen convex, either quite smooth or gently waved, frequently slightly prominent at R? 
(in this case sometimes nearly straight on either side of the prominence), but never with sharp angle or 
tail, tornus pronounced, cell more or less short, DC incurved, C approximated to cell for a short or 
quite moderate distance near base (in Section II usually anastomosing at a point or verv shortly). 
SC? stalked, M! stalked, connate or separate (Pl. 2, Fig. 13). 
Lanva. — Mostly unknown. That of sie/laria (which may be taken as representative of Section II) 
has the head rounded, slightly retracted, luteous with dense white granules; body green, with dense, 
secondary, pointed white granules ; angular subventral projections on abdominal segments 2 to 6, bearing 
tubercles IV and V; tubercle IV large. a long cone with manvw little spines to which various objects 
adhere; tubercles I to III small, V larger, VI and VII small ; the large tubercles are IV of abdominal 
segments 3 to 6, and III of segment 2, as is normal in the group. On flower-heads of Laníana camara
