 middle lobe prominent and nearly as wide as a lateral lobe.

Among the species of this Group with hind coxae of inter- 

 mediate length, the front face of the labrum nitid and finely 

 punctulate, and the pronotum and elytra closely punctulate, 

 this species is easily distinguishable by the antennal characters 

 indicated in the tabulation. The fourth joint of the antennae 

 longer than the third is an unusual character. The trilobed 

 outline of the head is feebly developed and not divided, the 

 middle lobe about two-thirds of a lateral lobe.
