This species is considerably smaller than the type of the genus 

 C. modcsta, described by Mr. Saunders in the 2nd Volume, N. S., 

 of our Transactions, p 29, pi. 3, figs. I, 2, and exhibits in a much 

 less marked manner the sexual peculiarities of the genus as shown 

 in the type, the prothorax of the male being scarcely angulated at 

 the sides, and the fore legs, with the tibias and tarsi, shorter, the 

 former part being almost destitute of the inferior crenulation, but 

 the outer edge is more distinctly bidentate ; the joints of the tarsi 

 are also destitute of the produced point on the underside. (See 

 PL III. fig. Id.) 



The upper surface of the body is thickly covered with very 

 minute punctures, each emitting a small luteous seta. The head 

 has the anterior angles rounded, the front margin elevated in the 

 middle and acute, the middle of the elevated part slightly emar- 

 ginate, the disc concave. Between the eyes is a small central, 

 raised, and polished carina. The antennse and palpi are pitchy. 

 The protliorax is almost conical in form, with the anterior trunca- 

 tion narrow ; the sides very slightly rounded and slightly margined 

 behind ; the hinder angles rounded, the hind margin nearly straight. 

 The scutellum and suture black ; the former but sh'ghtly punctured 

 and setose, the latter with two longitudinal carinas, down the disc 

 of the elytra, glabrous and impunctate. The epimera strongly 

 setose. The shoulders of the elytra much wider than the hind 

 part of the pronotum. Legs of moderate length. The fore tibiae 

 in both sexes with the external margins tridentate. The body 

 beneath is clothed with longer luteous setcB, especially at the sides. 

 The mesosternal process (formed as in C. viodesta), as well as the 

 centre of the abdomen (which is but slightly channelled in tlie 

 male), nearly naked and impunctate.
