LengtK one-fourth of an inch. 



Very much resembles C. /oenicu7n, hnt is much smaller, and 

 the elytra are very obviously punctured. We obtained speci- 

 mens on the Arkansa river; it is also an inhabitant of Pennsyl- 

 vania. The name hicolor is preoccupied by an insect of South 

 America. 



6. C. BREVILINEUM. — Black ; thorax bituberculate ; elytra vio- 

 laceous, with three abbreviated, white lines. 



Inhabits the United Sates. 



Body black, scabrous, with small, elevated points: head with 

 an impressed, longitudinal line : antennae nearly as long as the 

 body: palpi piccous: [414] thorax with dense, minute hairs; 

 two elevated, obtuse tubercles behind the middle and an inter- 

 mediate, elevated line, obsolete before : scutel hairy, rounded : 

 elj'tra violaceous, scabrous, with minute, subequal, numerous 

 tubercles ; base dusky, with minute hairs ; two or three longi- 

 tudinal, elevated, white lines on the middle, nearly parallel, and 

 placed in an obliquely transverse series; tip obtusely rounded : 

 thighs clavate. 



Length, male nine-twentieths ; female seven-tenths of an inch 

 nearly. 



I found a specimen in Pennsylvania some time since, and re- 

 cently an individual occurred on the Arkansa river. The white 

 lines of the elytra are very short, and nearly parallel to each 

 other; nearer to the base is sometimes another abbreviated white 

 line. 



7. C. FULVIPENNE. — Deep black, hairy; elytra fulvous. 

 Inhabits Arkansa. 



Body deep black, covered with dense black hair: antcnnre 

 rather longer than the body, somewhat hairy : palpi glabrous, 

 deep reddish-brovvn : thorax, above with four obsolete tubercles, 

 and an intermediate, abbreviated, glabrous, longitudinal line ; a 

 slightly prominent, lateral spine: scutel hairy, black: elytra yel- 

 lowish-fulvous, covered with dense, very short, prostrate hair ; 

 four longitudinal, slightly elevated lines. 



Length three-fifths of an inch. [415] 



I obtained but a single specimen of this beautiful species. It 



occurred at the Cherokee settlement on the Arkansa river. It
