Leconte, Ann. Lyc. Nat. Hist of New York, 4, 179; tab. 18, fig. 6. 
On sandy places near the Forks of Platte River. More slender and more convex than 
C. generosa, and distinguished by the larger and more prominent labrum. 
17. C. generosa, crassiuscula, supra fusco-eenea, vel nigro-purpurea, opaca, capite granulato-rugoso, fronte 
striata albo-setosa, thorace latitudine breviore, granulato-rugoso postice subangustato, lateribus albo-setosis, elytris 
punctatis parce granulatis, ad apicem subtilissime serratis, lunula humerali oblique prolongata, fascia media perpendi- 
culariter refracta, lunulaque apicali antice inflexa latis, albis ad marginem cohzrentibus, limbo extimo epipleurisque 
zeneis; subtus viridi-zenea, longe albo-pilosa, pectoris abdominisque medio glabro, pleuris purpureo-variegatis; labro 
sexus utriusque albo medio prolongato, tridentato. Long. -6—-7. 
Mas thorace convexo, postice subangustato, palpis labialibus articulo penultimo pallido. 
Femina thorace minus conyexo postice vix angustato, palpis labialibus articulo penultimo piceo.

C. obliquatat Kirby, Fauna Bor. Am. 4, 10. 
Variat maculis albis latioribus, ita ut lunulz humeralis margo posticus marginem perpendiculariter ferit; lunula 
postica quoque lobata haud inflexa apparet. 
Middle and Western States, (Connecticut, Pennsylvania, Wisconsin, Minnesota.) The 
variety is rare: but at a locality on the Mississippi above the Falls of St. Anthony I 
found them quite abundant: in one specimen the markings are fully as dilated as in C. 
formosa, from which it differs only by the middle band being rectangularly bent. 
18. C. formosa, crassiuscula, supra cuprea, vel cupreo-purpurea, opaca, capite granulato-rugoso, fronte striata 
albo-setosa, thorace latitudine breviore granulato-rugoso, postice subangustato, lateribus albo-setosis, elytris punc- 
tatis parce granulatis ad apicem vix serrulatis, lunula humerali, fascia media obtuse sinuata lunulaque apicali dila- 
tatis albis ad marginem late cohzerentibus, limbo externo epipleurisque zneis; subtus viridi-zenea albo-pilosa, pec- 
toris abdominisque medio glabro; labro sexus utriusque albo, medio paulo prolongato tridentato. Long. -64—-7. 
Sexus differentia sicut in C. generosa. ,

Valley of the Nebraska River, near sand hills. The marks of the elytra are always 
very broad, and the humeral lunule, though obliquely prolonged, is so dilated that its 
posterior outline is perpendicular to the sides: the only satisfactory difference between it 
and C. generosa is found in the middle band being only obtusely bent, and much less 
deflexed than in the last named species. 
19. C. latesignata, supra fusco-nigra opaca, capite thoraceque granulatis rugosis zeneo-tinctis, fronte subtilius 
striata albo-setosa, thorace latitudine breviore, postice vix angustato, parum conyexo, lateribus albo-setosis, elytris
