 tempora about one-third as long as the eyes, measured longitu- 

 dinally, and much less prominent ; antennjB stout, one-third as 

 long as the body, joints seven to ten strongly transverse. Pro- 

 thorax only slightly narrower than the head, transverse, convex, 

 very densely punctate, with two widely separated subbasal im- 

 pressions. Elytra fully three- fourths longer than wide, two-thirds 

 wider than the prothorax, parallel and ver}' feebly, evenly arcuate 

 at the sides ; humeri rounded to the prothorax and rather widely
