convex, finely and remotely punctured. Elytra broadly oblong, 

 convex, obsoletely excavated below the basilar space and within 

 the humeral callus, the latter' moderately prominent; surface very 

 finely punctured, the punctures arranged in longitudinal rows, 

 minute, coarser near the lateral boarder, nearly obsolete on the 

 hinder disk ; intermediate tibiae slightly emarginate. 



Smaller and less robust than C. robustus {ante, p. 104), the 

 antennae longer and narrowly dilated, the elytra more finely 

 punctured.

Face deeply but somewhat distantly punctured, separated from 

 the epistome and encarpae by a deep sutural groove; anterior 

 border deeply notched on either side, trilobate, the medial lobe 

 narrow, compressed, strongly produced ; a triangular space (from 

 the apex of whicli a narrow groove runs upwards to the vertex), 

 its base extending between the two lateral lobes, together with 

 the surface of the central lobe, deeply depressed ; epistome rather 

 longer than broad, campanuliform, its apex emarginate, surface 

 rugose- punctate ; encarpae broadly cultriform, smooth, impunc- 

 tate, the upper half slightly thickened; antennae nearly two thirds 

 the length of the body in the S , five upper joints narrowly di- 

 lated, nearly equal in width. Thorax scarcely broader than 

 long ; sides nearly straight and parallel from the base to just be- 

 hind the middle, thence slightly rounded and obliquely converging 

 to the apex ; posterior angles armed with a short tooth ; above 

 transversely convex, subconic anteriorly, the sides in front being 

 strongly deflexed; surface deeply but remotely punctured. Elytra 

 oblong, convex, deeply impressed below the basilar space and
