frontal carinae which terminate posteriorly in a short bifurcation. 
Frontal groove absent. Antennae stouter than in filiformis, the 
scapes reaching to about the posterior fifth of the head; first 
funicular joint not longer than broad; joints 2-10 decidedly

Thorax shaped much as in filiformis, long and narrow, without 
sutures, the dorsal outline even and straight, except anteriorly 
where it is feebly convex. Prosternal angles sharp; epinotal 
declivity perpendicular and concave, on the sides sharply mar-
