Prorocorypha,^ n. gen. 



Allied to Paropomala Scudder, but differing chiefly in the 

 great development of the cephalic portion of the head, the 

 greatly elongate supra-anal plate of both sexes and the sub- 

 genital plate of the male. 



Body sub-bacilliform. Head greatly elongate; vertex and 

 pre-ocular region strongly produced into a rostrate process, 

 fastigium lanceolate, tectate, carinate; antennse, at least of 

 male, somewhat triquetrous, subensiform. Cephalic and 

 median limbs very small. Caudal limbs very slender. Pro-
