194 LEPIDOPTERA HETEROCERA 
I49. GENUS CELIDOMPHAX, NOV. GEN., PROUT 
Celidomphax, nov. gen. Prout. 
Characters. — Face smooth. Palpus short (scarcely, if at all, longer than diameter of eye), 
second joint somewhat rough-scaled, third joint in both sexes small, smooth. Tongue present. Antenna 
somewhat over one-half, in c bipectinate with long branches. in Q nearly simple. Pectus hairy. Hind- 
tibia in both sexes with all spurs. Abdomen with a series of well-developed dorsal crests. Frenulum in gf 
from before basal expansion, in Q wanting. Wings ample, vermiculated. Forewing with costa arched 
distally, apex moderate, termen oblique, rather straight anteriorly, more curved posteriorly, cell not 
quite one-half, DC incurved, SC! from cell, free, SC? normal, R! very shortly stalked, M! approximated ; 
hindwing with termen rounded, tornus moderate, cell less than one-half, DC scarcely curved, only 
slightly oblique, C approximated to cell for some distance, then rather rapidly diverging, SC? stalked, 
M! stalked. 
Early stages unknown. 
Aspect rather of Cheroscelis or of Metacinela than of OmpAax; its actual affinities are somewhat 
doubtful. The two species are very closely related.

Pycnodontia. Warren, ibidem, Vol. 8, p. 206 (19or). 
Characters. — Face smooth. Palpus in both sexes minute (very rarely as long as diameter 
of eye), shortly rough-scaled (Pl. 5, Fig. 1 4). Tongue slender. Antenna rather short, in c either thick, 
nearly simple (lamellate) or bipectinate with short branches; in Q nearly simple, slightly lamellate. 
Pectus hairy. Femora slightly hairy. Hindtibia in c not dilated, in both sexes with all spurs developed. 
Abdomen typically with two or three very small crests, sometimes uncrested. Frenulum in cf present, 
from before some basal expansion, in Q wanting. Build rather robust, veins often thick (but see 
Section III). Forewing with costa arched (in éacofi straight), apex acute, in Q even minutely 
subfalcate, termen straight, usually becoming curved posteriorly, cell about one-half, DC* somewhat 
inbent, then very oblique outwards, SC! from cell, anastomosing strongly or slightly with C, 
or free, SC? normal, sometimes anastomosing shortly or strongly with SC! and very excep- 
tionally with SC?!, R! usually approximated, rarely stalked, R? from much above middle of DC, 
M! usually widely separate; hindwing with costa not short, apex moderate, termen gently rounded, 
never strongly convex, tornus moderate or pronounced, cell one-half or (usually) less, DC? inbent 
(usually strongly), then. very oblique outwards, C approximated to cell for a short or moderate
