 Griseus, more or less luteous on the front part of the 

 pronotum, robust, much more rounded than in 7'. bipunc- 

 tata H. Schf., and with a shorter, less acute head. Surface 

 of the head finely punctate with black, the base with four 

 almost impunctate, callous lines, tylus prominent, project- 

 ing a little beyond the lateral lobes, antennae slender, 

 the basal joint shortest, luteous, black at base and tip, the 

 second and third subequal, a little longer than the first, 

 dark, but blackish on the ends, third and fourth longer

 anterior margin, and with fine, black, distinct punctures 

 spread over most of the surface, the humeral angles blunt, 

 with the lateral margin blunth' diagonal, posterior margin
