C. unicolor Dej. Sp. Gen. 1, 52: 5, 210. 
Found in sandy places, in various parts of the Eastern, Middle and Southern States. 
The black race does not occur at the same localities with the green one, but on close 
comparison, nothing of specific character can be found to separate them. The form a is 
found in Georgia, Alabama and Florida, and is usually of a more obscure green than the 
type. 
9. C. seutellaris, viridi-cyanea, capite thoraceque haud nitidis, fronte fortiter striata, parce punctata et pilosa, 
thorace conyexo, confertim subtiliter rugoso, elytris flavescente-cupreis versus scutellum virescentibus, haud nitidis, 
brevibus convexis obsolete punctatis, versus suturam obsolete foveatis, puncto marginali ad medium lunulaque apicali

Valley of Platte River, on sand hills in June; not abundant. The colour of the head 
and thorax varies from full green to blue: the sides of the latter are less rounded in the 
male than in the female. The colour of the elytra also varies from coppery to brassy. 
10. C. nigrocerulea, nigro-purpurascens, sericeo-micans, fronte glabra subtiliter rugosa, utrinque striata, tho- 
race modice convexo, latitudine breviore, parce rugoso ad latera pilis parcis depressis albis, elytris minus convexis obso- 
lete punctatis, versus suturam seriatim foveis cyaneis impressis, lunula apicali obsoleta alba; subtus ad latera parce 
haud erecte albo-pilosa; labro sexus utriusque albo, maris obsolete, feminze distincte tridentato; palpis labialibus 
maris basi pallidis. Long. -6—-57. 
Leconte, Annals of the Lye. of Nat. Hist. of New York, 4, 181, tab. 14, fig. 9. 
One pair found near Bent’s Fort on the Arkansas River. The elytra of this species 
are more elongated than in the others of this group, and the sexual characters are differ- 
ent; yet by the indistinct punctures of the elytra, as well as by the absence of serrature 
and sutural spine, it seems to be here properly appended. It is a stouter species than C. 
punctulata, which it at first sight seems to resemble. 
GROUP Y. 
Labrum moderate, advanced in the middle, strongly tridentate. Head and thorax 
glabrous, finely rugose, the former finely striate between the eyes, the latter convex and 
strongly impressed. Palpi entirely black. Elytra strongly punctured, broadly rounded, 
and but very obsoletely serrate at tip, sutural spine distinct: spots small, the anterior 
ones in one species hardly ever visible. Body beneath very sparsely pilose. 
Differs from the next group by the bald front, and slightly serrate tips of the elytra.
