shows no tendency to approach II, while the hind legs have only 2 spurs. 
I look upon this genus as a development from Lymantria parallel to 
Aclonophiebia, from which it differs in position of vein 5, 7, and 10 in 
fore wmg and of 3, 5, 7, and 8 of hind wing ; the third joint of the palpi 
and the process of fore legs ; moreover, this process is absent in the $ of 
Aclonophiebia.

Description made from rhodalipha, Feld. 
Proboscis absent ; palpi just projecting beyond frons ; third joint 
slightly drooping ; first joint cylindrical, a little longer than broad ; 
second joint over 2 times first joint, but of same thickness; third joint 
about \ the length of second joint, very thin ; first and second joints with 
long woolly hair, moderately dense ; third joint less hairy ; eyes large, of 
width of frons ; frons smooth, covered with woolly hair ; antennae short, 
about J of costa, much curved, bipectinate ; basal joint of shaft with a 
hair tuft ; branches in A 6 times shaft, longest at J ; branches ciliated ; 
in $ the branches are shorter, about 2 times shaft, less ciliated, and ending 
in some bristles ; thorax and abdomen covered with long hair ; abdomen 
less than hind wmg in length ; legs moderately clothed with hair on tibiae ; 
tarsae with short hair ; fore tibia with a pointed, thin process as long 
as the tibia ; mid and hind tibiae with 2 short conical terminal spurs.

margin slightly rounded at vein 2 to 6 ; apex and tornus well rounded ; 
16 simple at base ; 2 from beyond f- lower median ; 3 from § distance 
2 to 4 ; 4 from lower angle ; 5 from just above the angle ; discocellular
