Head exserted, coarsely punctured on the vertex, which is 

 piccous; front smooth, nearly impunctate, impressed in the centre 

 with a short longitudinal groove ; epistome wedge-shaped, not 

 separated at the apex from the front, anterior border broadly 

 subangulate-emarginate ; encarpae separated from the front by a 

 deep piceous groove, which runs upwards along the upper border 

 of the eye ; jaw^s piceous, their apex black ; outer half of antennae 

 fulvous. Thorax one third as broad again as long, sides rounded, 

 scarcely converging in front, slightly sinuate just before the middle, 

 all the angles tuberculate ; transversely convex above, very re- 

 motely impressed with a few minute punctures on the disk; just 

 behind the anterior border is a transverse groove, extending 

 entirely across the thorax, its surface impressed with a single 

 row of punctures ; a short vitta on the central disk, the trans- 

 verse groove and the extreme base of the thorax, pale pice- 

 ous. Scutellum elongate-trigonate, its apex obtuse. Elytra 

 much broader than the thorax, parallel, excavated below the 

 basilar space, and slightly within the humeral callus, the latter 

 thickened, oblique ; basilar space slightly elevated ; surface very 

 finely striate-punctate, the punctures piceous, visible only under 

 a strong lens, with the exception of those placed on the subbasal 

 excavation, which are more strongly impressed. Thighs stained 

 near the apex with piceous.
