length from eye to vertex: flatly convex above, depressed in front, a little 
tumid beneath; vertical margin straight, temples rounded, eyes convex; 
antennez a little longer than the head, pedicel about twice as long as wide, 
following segments scarcely longer than wide, antennal fosse deep; clypeus 
reduced by erosion from the sides to a thin, carinate ridge, apically depressed 
and projecting slightly in front of the anterior margin of the head, declivous 
at the sides, the carina extending backward on the top of the head beyond 
the base of the antennze; mandibles slender, curved, truncate apically and
