Key to Genera. 



Genae broad, their width as great as the length of first 

 segment of antennae, eyes therefore distant from base of 

 mandibles; eyes round or short oval in outline, inner 

 margin always convex Dolerus p. 69 



Genae narrow, their width distinctly less than the length 

 of first segment of antennae, eyes therefore adjacent to 

 base of mandibles; eyes elongate and emarginate on their 

 inner margin Loderus p. 76
