J]lona;atus, sulicylindricus, metallico-purpureus, nitidus, inter- 

 dum viridi micans ; tliorace disperse sat fortiter punctato ; 

 elytris infra basin fortiter transversim excavatis, juxta marginem 

 lateralem longitudinalitcr sulcatis, subseriatim punctatis. Long. 

 4-5i lin. 



Mas. Antennis corporis dimidio multo longioribus, articulis 

 sex Tiltimis comj^ressis, paullo dilatatis. 



FiPin. Antennis brevioribus, articulis sex ultimis sat valde 

 dilatatis ; elytris intra sulcum laterale costatis. 

 Ilab. The Hills and Plains ; Dibru. 



Vertex strongly but not very closely punctured ; front 

 impressed with a longitudinal groove, which terminates just 

 above the apex of the clypeus in a large ill defined fovea; clypeus 

 rather broader than long, semi-ovate, separated from the front 

 on either side by a deep groove, its extreme apex transversely 

 depressed ; surface closely punctured, clothed with fulvous 

 hairs; antennae nearly three fourths the length of the body in 

 the $ , the six outer joints only slightly dilated, scarcely more 

 than half the length of the body in the 9 , the six terminal 

 joints in this sex more broadly dilated. Thorax rather more 

 than one half broader than long ; sides straight and slightly 

 converging from the base to the middle, thence rounded and 

 converging to the apex ; disc convex, subcylindrical, sparingly 

 punctured, impressed on either side, just behind the middle, 

 Avith an ill defined fovea. Elytra narrowly oblong, convex, 

 impressed below the basilar space Avith a deep transverse, slightly 

 curved sulcation ; just within the lateral margin in both gexes is 

 a broad ill defined longitudinal groove, within this in the ? is a 

 narrow elevated longitudinal costa, which extends from the 

 humeral callus nearly to the apex of the elytra, claws appendi- 

 cidated. 



In habit closely resembling C. aspJiodelus, Marsh., separated 

 from that insect by its broader thorax, by the longitudinal costa 

 on the elytra in the ^ > and by the six (not five) dilated outer
