NEW SPECIES OF INSECTS; 21 



outer margin of each elytron white, with two abbreviated 

 bands, and an intermediate refracted one ; trochanters 

 purple. 



Inhabits North America. 



Head coppery, varied with green and. blue. Lahrum 

 and base of the mandibles white. Thorax very hairy, 

 impressed lines blue. Elytra punctured irregularly with 

 green, a marginal lunule at base, the extremities of which 

 arc almost equally prominent; the band is divaricated on 

 the margin so as to join the anterior lunule, but is inter- 

 rupted before the terminal lunule, abruptly refracted at 

 the centre of the elytron and curved near its termination, 

 towards the suture. Body beneath green, very hairy. 

 Length rather more than half an inch. 



Common in Pennsylvania, very much resembles C 

 trifaciata, for which it is probable it has generally been 

 mistaken. 



5. C. pusilla. Above black, obscure; elytra with two 

 lunules and a recurved band, white. Body beneath black* 

 blue, or greenish. Trochanters testaceous. 



Inhabits with the first. 



Elytra with a marginal lunule at base and another 

 at the tip, both very narrow and white ; an intermediate 

 band, divaricate on the margin, recurved at the middle of 

 the elytron and terminating near the suture behind. La- 

 brum and base of the mandibles whitish; the four basal 

 joints of the antennae purple. 



Length not quite half of an inch. Found by Mr. 

 Nuttall. The band is often obsolete, or only detached 

 portions of it are visible, the enlarged marginal part is 

 permanent.
