This species evidently belongs to Dr. Horn's Group IV. (Tr. Am. Ent. Soc. xiii. 

 p. 84), and is most nearly allied to C. pusilla, Lap. & Gory. The prosternum has the 

 anterior margin slightly arcuately advanced ; in the male it is closely and rather strongly 

 punctured and pubescent, with a narrow smooth median line ; in the female the punc- 

 tures are less close, and the smooth part is much wider at the apex, the latter with only a 

 few punctures and scarcely any pubescence. The head in the male is densely punctured, 

 rather dull, with a smooth longitudinal line on the vertex ; in the female it is more 

 shining, much more coarsely but densely punctured; there are traces of two small 

 smooth spots, more conspicuous in the female than in the male; the clypeus has the 

 emargination rather wide and deep, slightly angular, with the lateral lobes straight in 

 front. The anterior tibiae are only slightly curved, enlarged at the apex for rather 

 more than one-third their length. The abdomen has the last ventral segment semi- 

 circularly emarginate at the apex in the male, somewhat triangularly notched in the 

 female. The elytra have the sutural costa almost parallel to the suture and not curved 

 away from it at the apex ; the second costa is somewhat irregular, commencing about 

 the middle of the elytra, and makes more or less of a curve near the apex ; the third 

 costa is only indicated by a slight irregular ridge at about the middle ; there is a 

 transverse shallow impression on the disc before the middle, a smaller round one at the 

 apex of the third costa, with some irregular smooth marks above and below it, and 

 between the sutural costa and the second costa are two vague smooth spots (one above 

 the other) not far from the apex.
