Elytra elongate oval, widest at middle and more attenuated pos- 

 teriorly ; hase truncate or feebly emarginate, slightly wider than the 

 contiguous prothoracic base; humeri obtuse and more or less rounded; 

 sides evenly arcuate and slightly sinuate at apex, the latter pro- 

 duced, forming a moderately long, horizontal, or slightly down- 

 wardly oblique cauda ; disc feebly convex on the dorsum, rather 

 strongly rounded laterally, and somewhat gradually, arcuately de- 

 clivous posteriorly ; surface more or less striato-punctate, very vaguely 

 sulcate, punctures near the suture scarcely muricate, more strongly 

 so laterally and on the apex, serial punctures of the strite moderate 

 in size and closely placed, the interstitial series similar and more dis- 

 tantly spaced, both series becoming irregular laterally and on the 

 apex; suture impressed on the cauda, the latter emarginate at tip; 

 each puncture with a long flying hair. 



Eplpleurcc moderate in width and gradually narrowing from base 

 to apex, where they dilate to form the inferior surface of the cauda ; 

 surface opaque and obsoletely punctulate. 



Sterna more or less punctate and rugose, sparsely clothed with 

 long brownish hairs. 



Parapleurce coarsely punctate and not noticeably pubescent. 



Abdomen horizontal and more or less ventricose in both sexes, quite 

 closely punctate, most densely so on the first and fifth segments. 



Legs moderate in length and thickness, densely sculptured and 

 clothed with long, flying, sparsely distributed hairs. Anterior 

 femora mutic in both sexes; anterior tibial spurs acute, subequal, 

 moderate in length, and more or less curved. Tarsi similar in the 

 sexes.

 to the prothoracic base. Elytra slightly narrowly oval. Abdomen 

 very feebly flattened on first two segments. 



Female. — Rather robust. Antennae scarcely attaining the pro- 

 thoracic base. Elytra quite broadly oval. Abdomen strongly 

 convex.

Apicale elongate, nearly as long as the basale, and triangular; 

 surface quite evenly and moderately convex, with a narrow median 

 and more or less obsolete groove in basal two-fifths; sides moderately 

 arcuate in basal half, thence more or less sinuate to apex, the latter 

 produced and acute, not deflexed; base broadly rounded at middle,
