 area. The mandibles are distinctly longer than the head, and 

 the upper tooth is longer, and placed nearer the middle.

(J. Black and very shining, the antennae and tarsi dark I'ed, 

 Avith yellow hairs, the abdomen scantily clothed with short 

 setae. Cylindrical and convex, parallel-sided, with short legs 

 and very short antennae. The head is broad and convex, Avith 

 a deep, rather triangular depression in front, the front margin 

 rather sharj)ly pomted between the mandibles. The head is 

 finely and scantily punctured behind and the sides are very 

 deeply and coarsely rugose, forming seven or eight strong 

 oblique parallel ridges. The mandibles are as in C. atavus, 

 armed with a strong tooth just behind the middle, and directed 

 obliquely inward and upward. The pronotum is very short and 

 broad, rather more strongly punctured than that of C. atavus, 

 completely margined, .very deej^ly at the sides and base, the 

 sides very feebly angulate behind the middle, the front angles 

 produced, the hind angles sharp. The elytra are deeply 

 grooved, the intervals strongly convex and fairly strongly but 

 irregularly punctured. The sides are parallel, a little less 

 broadly margined tlian those of C. atavus, the extremities 

 .^emicircularly rounded. The mentum is very t^hort and broad, 

 very deeply hollowed. 



The female is unl^nown.

The figure accompanymg the original description of this 

 species gives a rather inaccurate representation of it. It is 

 a cylindrical insect, with a very short thorax and parallel-sided 

 elytra, and verj^ closely resembles C. atavus, the only obvious 

 difference being in the deeply grooved elytra, with A\'ell-pnnc- 

 tured convex intervals. The sides of the head behind the eyes
