Body oval, rounded ; thorax coarsely punctured ; scutellum black, which gives 

 the sutural vitta the appearance of extending to the prothorax ; elytra pale 

 yellow, with punctures on the suture and vittae which do not reach the apex or 

 base, outer margin of the vitta slightly and obtusely sinuous ; the vitta is some- 

 times partially divided by a yellow line, and may sometimes form two vittae ; in 

 another specimen the sutural and discoidal vittae are confluent ; antennae, legs 

 and under surface brownish black.

 dorsal vitta dark bronzed. Tab. 1. fig. 13.

This species differs from the preceding in the shape ; it is quite oval, whereas, 

 C. pulchra is round ; the emargination of the outer margin near the middle is 

 more angular and sudden. 



17. C. praecelsis. Oval, convex, ferruginous ; thorax with a yellow margin; 

 elytra pale yellow, with fine punctures ; legs, thorax and under surfixce ferrugi- 

 nous. Tab. 1, fig. 14. 



Length. -31. 



Locality. Kansas river. 



Thorax with the disc coarsely punctured, with a narrow yellow margin at the 

 side impunctured ; elytra with fine punctures on the suture and dorsal vittae, 

 with a broad sutural vitta suddenly narrowed at the base, and a broad bronze 

 brown dorsal vitta, narrowed at the apex and base. 



18. C. elegans. Oval, metallic black ; thorax yellow, with a black mark at 

 the base ; elytra pale yellow, with a black suture and dorsal vitta.

There is great variety in the marking of the thorax and elytra, the markings 

 in some specimens are very faint, and in others wanting. I have not been able 

 to make any comparison between this and the European species, and I give it 

 as identical on the authority of Kirby. 



20. C. arctica. Oblong, oval, elongate, ferruginous ; head black; thorax 

 with two basal black spots usually confluent, coarsely punctured ; scutellum 

 black ; elytra ferruginous, with ten black spots ; legs black, with the tibiae and 

 tarsi red. 



Length. -26.
