Many taken in the Expedition, and apparently abundant in N. America. I 

 received it many years since, but without a name, from my lamented friend Pro- 

 fessor Peck. 



DESCRIPTION. 



Body above greenish-copper, underneath golden-green clouded with blue. Labrum white, tri- 

 dendate slightly prominent in the middle ; mandibles white at the base, black at the tip ; palpi 

 black; labial with the intermediate joint rufous, darker at the tip. Elytra with a large white 

 humeral crescent, extended at the lower end obliquely beyond their middle ; mesal band bent down- 

 wards, recurved at the end, and connected by a marginal line with a crescent at the apex. 



In the male the intermediate joint of the labial palpi is white, and the mesal band is not connected 

 with the terminal crescent.

A common species in all N. America. 



DESCRIPTION. 



Very nearly related to C. obliquata and regarded by Count De Jean as synonymous with it. 

 They differ however in the following particulars. In C. vulgaris the upper surface of the body 

 is nearly black, without any tint of bronzed-green. The humeral crescent of the elytra is slenderer, 

 and its lower extremity does not approach so near the mesal band. In the females the intermediate 

 joint of the labial palpi is black. In the males the underside of the body, with the exception of 

 the anus, is of a fine blue instead of a golden-green.
