however, it is short and abrupt. The palpi are 
longer than the head, rather remote from each other, 
and not converging, the point curving downwards ; 
the radical joint short, the terminal one, in certain 
species, not half the length of the second, and ob- 
tuse, while in others it is more than one half longer 
than the second, and acute at the apex. The ante- 
rior wings are sometimes angular, at other times 
rounded, the hinder pair denticulated in moBt, but 
entire in II. Cassiope,Damis, Hero, and Pamphilus ; 
the basal areolet of the secondary wings closed. 
The fore-legs are very short in both sexes, the others 
with bifid claws. The chrysalis is double-beaked, 
and is suspended perpendicularly.
