The species ranges from Kansas to the desert regions of southern 

 CaHfornia. The following localities are represented in the material 

 at hand: Kansas (Wallace); Colorado (Boulder); New Mexico 

 (Cloudcroft, Santa Fe, Highrolls) ; Utah (Douglass, Stockton, Eu- 

 reka) ; Arizona (Chiricahua Mts., Bright Angel).

C. limbatus Lee. Smith. Miscel. Coll., 1S63-66, VI, p. 94. 



Head greenish black, pale yellow in front as far as the eyes, prothorax 

 immaculate, elytra dark blue or green with the suture and entire apical and 

 lateral margins pale. Antennae strongly serrate, entirely pale in the (^, the 

 outer joints more or less dusl-cy in the 5- Venter pale yellow with lateral black 

 spots in the 5. the latter feebler or absent in the (^ ; legs varying from entirely 

 pale except the hind femora to dark with the front and middle femora pale. The 

 basal joint of the (^ antenna is robust, triangular, somewhat longer than wide, 

 not excavate posteriorly ; second joint wider than long, appendage rather long. 



This is a pretty species, best known by the broad parallel elytral 

 vittse and widely serrate J' antenn?e. The type is from Nebraska. 

 Other localities known to me are Wallace, Kansas (Knaus) ; Browns- 

 ville, Texas (Schaeffer) ; Pecos, Dimmitt Lake, and Roswell, New 

 Mexico (Cockerell) ; Tucumcari, N. Mex. (Wickham) ; Clear Lake, 

 Utah (Wickham) ; Independence, California (Wickham). The 

 Brownsville and Independence specimens are not quite typical but 

 do not appear to be specifically distinct ; the latter has a small tho- 

 racic spot.

In the color of the head and the entirely pale under surface and legs, this 

 species is almost unique. Certain specimens of marginellus have the head in 

 part or entirely pale and the under body and legs also completely pale, but in 

 these the prothorax is polished and the elytral margins entirely yellow. The 

 antennal characters are almost precisely as in tricolor and sublimbatus.

 tion was drawn. 



C. flavicinctus Fall. Trans. Am. Ent. Soc, XXXVI, 1910, p. 140. 



This species is at once distinguished from all others described by the long 

 erect hairs being entirely pale. The head is pale yellowish testaceous in front 

 of a line joining the middle of the eyes; prothorax black, highly polished, with 

 very narrow pale side margins ; elytra blue-black narrowly margined throughout 

 with pale yellow, surface a little uneven and feebly shining. Antennae pale 

 yellow, outer angles of intermediate joints slightly infviscate. Tarsi and hind
