 prothorax globose; elytra wide, convex, non-striate, sparsely 

 setose, a strong narrow transverse impression across disc at basal 

 fourth, inflexed margins glabrous; tarsi hairy above, fourth joint 

 entire. Piceous-black;* antennae, mandibles, condyle of head, 

 lateral channel and inflexed margins of elytra, and a narrow 

 transverse posthumeral macula testaceous-bro\vn, at bottom of 

 external part of transv^erse elytral depression, a small pale round 

 macula on apical declivity of each elytron opposite apical sinu- 

 osity; legs testaceous, with apical third of femora, base and apex 

 of tibiae and tarsi more or less infuscate. 



Head wide(l mm. across eyes), convex, glabrous; one supra-
