 cles feeble. Clypeus with indistinct sutures. Antennae mode- 

 rately long, first joint almost as long as the second to fifth com- 

 bined, four terminal joints rather stouter than usual. Pro- 

 thorax rather strongly transverse, base largely but not suddenly 

 narrowed ; with a narrow and moderately distinct median line ; 

 with moderately dense and comparatively small punctures, the 

 interspaces densely and minutely punctate. 'Elytra distinctly 

 wider than and al)Out once and one-half the length of prothorax,
