 longer and coarse, pale and more conspicuous on the elytra but 

 strongl}^ recurved. Head triangular, wider than long, the eyes 

 moderate in size and convexity, coarsely faceted and adjacent to 

 the prothorax ; antennal prominences large and pronounced ; pro- 

 duced front between the very widely separated antennae trans- 

 versely^ convex, evenl^^ rounded at apex, fused with the clypeus 

 and coarsely, densely punctate laterally ; mandibles stout. An-

 second joint shorter than the first but equally stout, cylindric, |- 

 longer than wide, shorter than the next two but \Qvy much 

 stouter ; three to six subequal and slightl}^ elongate ; seventh 

 much larger, full}^ ^ thicker, obconic, nearly ^ longer than wide ;

 long as the prothorax and not wider, the sides parallel and feebly
