Head flat ; eyes lengthened, each with a sinus on its inner margin 

 above the middle, below their margin not reaching the base of the

 ocelli close together ; antennae stout, filiform in the male, the apical 

 three joints suddenly attenuate and convolute ; clypeus wedge-

simple. VV mgs— fore wmg with the radial cell elongate, very nearly 

 attammg the apex of the wing; three cubital cells, the cubital 

 nervure only faintly continued to the apex of the wing ; the 1st 

 cubital cell long, much longer than the 2nd and 3rd united, the 

 2nd the smallest, receiving both recurrent nervures and stronHy
