cj. Antennae with joint 1 curved, widened from near the base, 

 2 with a very long, curved appendage, 3-9 feebly serrate, 3 a little 

 longer than 4. 



Hab. Lower California; Mexico; Guatemala; Ni- 

 caragua; Venezuela. 



A large, variable form, with quadrimaculate elytra, 

 distinguishable amongst its allies by the concave, smoother, 

 subglabrous space on each side of the head anteriorly, thi^A 

 being especially conspicuous in the male. The testaceous 

 portion of the front of the head is equally developed in the 

 two sexes, and always angularly excised in the middle. 

 C. geminus has two evanescent black spots on the prothorax, 

 and the anterior femora in some examples ruf o-testaceous ; 

 C. decorus has an immaculate prothorax and the legs 

 sometimes in part testaceous ; C. validus has the prothorax 

 spotted or immaculate, and the legs wholly or in part, 

 and the abdomen, testaceous. The male-antenna (of 

 C. validus) has been figured by Horn. Gorham, for want 

 of material, left the determination of C. decorus as some- 

 what doubtful. The pale-legged form (C. validus), the 

 type of which was from Yaqui in Sonora, has been found 

 at Acapulco and Mazatlan by Hoge, and at Presidio and 

 Milpas in Durango by Forrer, all these locahties being in 

 N. Mexico. The elytra usually have the outer limb 

 testaceous from a httle below the shoulder, but in one 

 specimen the second spot reaches the outer margin.

 3-9 subequal, moderately serrate; anterior femora rufo-testaceous.
