Oblong-ovate, form rather light; prothorax with anterior angles 

 porrect, posterior angles rounded, base lobate, marginal channel 

 wide, bipunctate; elytra oval, bipunctate on apical third; anterior 

 tibke tridentate, outer edge denticulate above three large teeth. 

 Black, shining, elytra faintly suffused with violet on lateral 

 declivities, lateral channels of elytra and prothorax cyaneous- 

 purple. 



Head transverse (3*5x5 mm.), smooth, strongly declivous on 

 sides, not longitudinally impressed on sides of occiput; front 

 rather depressed ; frontal sulci deep, elongate, lightly divergent 

 posteriorly; clypeus deeply emarginate-truncate in middle, inter-
