Ovate, very convex, nitidous. Face fumisbed between the eyes 

 and just above the insertion of tbe antennae witb two transversely 

 placed, shining tubercles ; jaws, labrum, and antennse black, the latter 

 rather more than half the lengih of the body, several of the basal 

 joints fiilvous beneath. Thorax convex, smooth, and indistinctly pimc- 

 tm-ed on the disk, slightly and singularly excavated on the side just 

 within the lateral border, side margins angustate-rotuudate. Elytra 

 shining black, their basal fourth, together with the inflexed limb, 

 fulvous, each elytron impressed with eleven rows of very fine punc- 

 tui-es, the first row short ; these striae, however, are discovered with 

 difRcidty, owing to the nearly equally well-marked punctatiou of the 

 perfectly plane interspaces ; near the outer margin, just below the 

 humeral callus, is a shallow smooth fovea. Tibiae unarmed.
