bluish, the bilobate disk cupreous ; scutel blue ; elytra dull 

 olivaceous-green, with a slightly cupreous tint and blue margin, 

 four white dots and refracted band ; of the anterior marginal 

 dots, one is placed on the humerus, and the second equidistant 

 from the band, which is refracted at the centre of the elytron, 

 and terminated near the suture, in a transverse line with the 

 penultimate spot ; this last is large, submarginal, and orbicular ; 

 terminal spot transversely triangular, and with the first interrupt- 

 ing the margin j sutural angle not mucronate. Abdomen, 

 venter bluish-green, with a few hairs each side ; tail purple. 



The specimen from which this description was taken is a 

 female ; it resembles C. purpxirea in its differently colored elytral 

 margin, but is sufficiently distinct from that insect by its more 

 numerous spots, &c. [424] 



[The figure is so different from that given in American Ento- 

 mology, ante 1, 34, that it is impossible to believe that both have 

 been taken from the same specimen. The present figure evi- 

 dently belongs to one of the western varieties of C. punctulata, 

 but the description does not agree with that species. — Leg.] 



12. C. PUSILLA. — Body above blackish obscure, beneath 

 black-blue or greenish ; trochanters testaceous ; elytra with two 

 lunules, an intermediate band, which is divaricated on the 

 margin.

Inhabits with the preceding. 



Desc. Head dark green, obscure ; antennoe fuscous, bronzed- 

 testaceous or greenish at base ; labrum white sinuate, and 

 brown on the edge, with six or eight marginal punctures ; palpi 

 testaceous, bronzed at tip ; front naked. Trunk obscure ; thorax 

 with the impressed lines not differently colored ; elytra black, 

 each with two lunules and a recurved band, attenuated, anterior 

 lunule elongated, much narrowed, acute at tip, posterior one not 

 dilated at the suture, and incurved from the margin ; band 

 dilated near the margin into a triangle, recurved before the mid- 

 dle, and passing very obliquely and nearly in a right line, to its 

 termination near the suture, sometimes obsolete at tip ; feet testa-
