Head deeply punctured, impressed in the middle with a longitu- 

 dinal groove, which runs downwards from the vertex nearly to 

 the lower margin of the front, where it terminates in a triangular 

 depression ; the front separated from the epistome by a deep 

 groove, its anterior border rounded, slightly produced in the 

 middle, subsinuate on either side ; epistome broader than long, 

 sides gradually converging backwards, anterior border sliglitly 

 but distinctly angulate-eraarginate, upper margin broadly con- 

 cave, surface rugose-punctate ; encarpae cupreo-aureous, nar- 

 rowly cuneiform, their extreme upper surface slightly thick- 

 ened ; antennae rather more than half the length of the body, 

 five outer joints black, moderately dilated, the seventh to 

 the ninth gradually increasing in width. Thorax transverse, 

 nearly a third broader than long ; sides rounded, slightly converg- 

 ing in front, hinder angles armed with a distinct tooth : above 

 transversely convex, sides strongly deflexed in front; surface 

 coarsely and rather closely punctured ; on either side is a broad 

 but ill-defined shallow excavated space. Elytra broadly oblong, 

 convex, coarsely punctured, the puncturing arranged in double 

 longitudinal rows, alternate interspaces on ihe outer disk, toge- 

 ther with the apical portions of those on the inner disk, costate ; 

 two or more of the costae below the humeral callus are interrupted 

 and irregular; humeral callus prominent, bounded within by a 

 longitudinal depression ; the middle of each elytron, below the 

 basilar space, broadly excavated.
