Characters. — Face smooth, or slightly roughened below. Palpus moderate to longish (rather 
short in convallata, both sexes), second joint moderately rough-scaled (usually with some projecting 
hair-scales above and beneath), third joint smooth, in cf more or less short, in Q shortish to moderate, 
very rarely long. Tongue present. Antenna moderate, in c bipectinate, typically with long, coarse, 
iong-ciliated pectinations, which diminish with great suddenness, apical one-third (less in znvidens and 
perhaps a few others) nearly simple; in Q nearly simple, lamellate. Pectus slightly to moderately 
hairy. Femora usually glabrous. Hindtibia in C! usually dilated with hair-pencil. in both sexes with 
all spurs. Abdomen not crested. Frenulum in cf slender, but of good length, arising from before 
rounded basal expansion; in Q wanting. Wings usually smoothly scaled, not infrequently somewhat 
iridescent. Forewing with costa usuallv arched, apex acute, termen oblique, straight or slightly curved, 
cell less than one-half, DC incurved, SC! from cell, or occasionallv connate or short-stalked, usually 
free, SC? normal, very rarely anastomosing at a point with SC!, R! connate or shortsstalked, R? from 
above middle of DC, M! approximated to R?; hindwing with termen entire or weakly subcrenulate, 
angled or tailed at R?, tornus pronounced, inner margin long, cell short, DC curved, becoming oblique, 
C approximated to cell for some distance (very rarely with slight anastomosis), then rapidly diverging, 
SC? stalked, R? characteristic, M! stalked (in cowami sometimes connate). C genitalia : uncus pointed, 
with rounded socii; gnathos pointed, very slightly scobinated ; harpe simple, with raised fold; vinculum 
with slight central projection at the base; penis pestillate; eighth sternite double lobed. Apparently 
related to Prasinocyma, Iodis, etc. 
Early stages apparently unknown. 
We have given, under the preceding genus, some notes on the differentiation of Ge/asma there- 
from. From Prasinocymá, to which it is still more closely related, it may generally be distinguished by 
the shape of the hindwing, that of Prasinocyma being very seldom at all definitely quadrate or elbowed, 
and oftenest perfectly rounded; the shorter third joint of the Q palpus (only at all elongate in a few
