The head is larger than in any other species that I have seen, the meta-

This somewhat resembles rclivtiis, but is smaller (L. 0.68. Br. 0.72 in.), 

 the antennae are dark and the eyes slightly contracted below, the head 

 smaller, the metathoracic spiracles oval and the edges of the basin some- 

 what defined.

with the sides sharply defined. 

 The male resembles the female.
