Very similar in form to the next species. Second joint of antennae 

 not twice as long as the first ; thorax rounded behind, naiTOwed 

 and sinuate in front ; elytra impressed with large, deep, round 

 punctures, arranged in striaj, but the punctures themselves more 

 distantly placed in the rows than in C. tarsata, striae confused 

 on the sides ; alternate interstices towards their apex subcostate ; 

 posterior angle armed with a short tooth ; apical margin obsoletely 

 dentate ; a patch on the scutellar region and two transverse spots 

 on the disc of each elytron, one before, the other behind the 

 middle, the anterior common. Idack. (Tab. IX. fig. 9.)

C. subenneiformis, subdepressa, supra pallide fulva ; antennis nigris ; 



subtus nigra ; thorace, femoribus tibiisque fulvis. 

 Long. 3 lin. 



C. somewhat wedge-shaped, subdepressed, pale fidvous above ; an- 

 tennae black ; eyes piceous ; beneath shining black ; head, thorax, 

 thighs and tibiae fidvous. Head smooth, indistinctly angled in 

 ft-ont, impressed on the vertex -with an oblong fovea ; antennce 

 eqiial in length to half the body, moderately robust, slightly in- 

 crassate, second joint twice as long as the fii'st, four terminal joints 

 short. Thorax transverse -quadrate ; sides narrowly margined, 

 rounded just behind the middle, slightly subsinuate at the base, 

 narrowed and sinuate in front, anterior angles produced into a 

 subacute tooth ; above subconvex, transversely impressed on the 

 hinder disc, coarsely and closely punctured ; a broad, shining, 

 longitudinal space down the middle of the disc, nearly free from 

 punctiu'cs. Scutellum smooth and shining. Elytra broader than 

 the thorax, rather wider towards their apex ; sides narrowly mar- 

 gined, subsinuate below the shoulders, posterior angles distinct, 

 armed -with a short flattened tooth ; apex (Tab. IX. fig. 10) regu- 

 larly rounded, apical border scarcely dilated, finely dentate ; above 

 flattened along the back, convex on the sides, shoidders prominent, 

 laterally produced, their apex subacute, scarcely extending beyond 

 the outei- border of the elytron ; the surfoce of each elytron im-
