GENUS HIPPARCHIA. 185 



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 most, but 

 entire in H. Cassiope, Davus, 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.
