202 LEPIDOPTERA HETEROCERA 
long, decreasing branches, in Q nearly simple. Hindtibia in both sexes with terminal spurs only. 
Abdomen not crested. Frenulum in & short, from before basal expansion, in Q wanting. Forewing 
rather broad, with costa slightly arched, apex moderate, termen gently curved, oblique, cell less than 
one-half, DC incurved, oblique posteriorly, SC! stalked, SC? normal, R! stalked to beyond SC!, M! separ- 
ate; hindwing with termen waved, somewhat convex, tornus rather pronounced, cell short, DC? very 
oblique posteriorly, C anastomosing with cell at a point near base, rapidly diverging, SC* stalked, 
M! separate. 
Ecc. — Elliptical. strongly flattened above and below, but rounded, one end depressed from 
side view ; shagreened, scarcely reticulate (Dvar, Psyche, Vol. 5, p. 118). 
Lanva. — Head strongly bilobed, the lobes increasing in sharpness in later stages, becoming 
conical horns, prothorax high, with two forward-directed prominences; body otherwise without special 
protuberances, slender, stiff, cylindrical, minutely frosted with white granules, legs short, anal plate 
pointed cordate. A remarkable mimic of a young twig of its foodplant, Condaiea ferrea (Dyar, loc. cit., 
who fully describes the five stages). 
PupaA. — Light brown with darker cases and broken dorsal line; in an imperfect net of threads 
among leaves (Dyar, loc. cit.). 
(The systematic position of this genus is somewhat uncertain. Except in shape and some minor 
points of venation, its characters seem to be nearly those of PamfAlebia, but it is scarcely likely that, 
with that genus, it is an offshoot of Microloxia. It is on the whole more likely that it springs from the 
Oospila-group, though with several specializations which remove it therefrom in our scheme.
