metallic-blue, this blue area being extended somewhat further 

 forward in the middle, with its anterior margin rounded. Head 

 distinctly but rather sparsely punctured in front, without raised line 

 or carina. Antennae three-fourths the length of the body ; scape 

 equal in length to the third joint, slightly thickened towards the 

 apex, thickly punctured, asperate near the apex. Prothorax 

 sparsely punctured, except along the middle of the centro-notal 

 elevation, which is smooth. Elytra rather thickly punctured on the 

 basal testaceous area.

9 . Antennae, and the apical fifth of the elytra black ; all the rest 

 of the body pale yellowish-testaceous. Head almost impunctate ; 

 front with a very feeble median carina in its lower half. Antennae 

 nearly as long as the body ; first joint a little shorter than the third, 

 asperate over nearly the whole of its anterior face. Prothorax very 

 slightly protuberant at the middle of each side ; the centro-notal 

 elevation sparsely punctured, ill defined in front, distinctly limited 

 behind by the backwardly deflexed part of the posterior groove. 

 Elytra slightly widened out posteriorly, rather thickly punctured 

 except near the apex.

In the remaining species of the genus, the scape of the 

 antennae is shorter than the third joint, and the last joint 

 is entirely pubescent and not very sharply pointed : the 

 prothorax is more distinctly protuberant at the middle of 

 each side, its anterior groove is continued across the 

 pronotum, its posterior groove is less strongly bowed back 

 in the middle, and the central elevation, lying between 

 these grooves, is more strongly raised. 



These include C. albicomis, Pasc, G melanura, Pasc, 

 and G. tabida, Pasc, in addition to the following :

9 . Head and prothorax reddish-testaceous, the elytra of a paler, 

 yellowish- testaceous colour ; underside, legs, and antennae, testaceous. 

 Head sparingly punctured. Prothorax with a slight elevation on the
