 on the sides, gently narrow- 

 ing towards the base; pos- 

 terior angles rounded otl',

 the inner side of the lateral

 the base; posterior marginal 

 punctures in the lateral 

 border at the basal angles. Elytra oval, not convex, a little 

 narrower towards the base, rounded on the sides, broadest just 

 beyond the middle, sinuate behind, dehiscent at apex, sides and

 angles not marked. Abdominal segments normal. 



Ohs. — The third interstice of each elytron has a series of punc- 

 tures, but as the number is not uniform, there l^eing six on the 

 right elytron and four on the left, these impressions can scarcely 

 be accepted as speciflc characters.
