28 COLEOPTERA OP KANSAS 



head, excepting the antennas, front and mouth, which are black. The outer inter 

 vals of the elytra are not shining, and are alternately a little more convex, as in 

 M. vittata, and the edge is not serrate.

 Long. -2G. 



One specimen, found near Long s Peak. Allied by the declivous and scarcely 

 explanate but narrowly reflexed elytral margin, to C. Q-punctata and C. 9-macuJata, 

 but differing by the more narrow, regularly elliptical form of body. The legs in 

 C. 9-maculata are black ; in C. Q-punctata they are reddish yellow, but the punc 

 tures of the strife of the elytra in that species are less approximate, each elytron is 

 marked with three black spots, the humeral angles are more prolonged, and the 

 side angles of the thorax are more rounded. Still more essential differences exist 

 in the antennae: in the present species the 2d joint is a little longer than wide; 

 the 3d is slender, one-half longer than the 2d; the 4th, 5th, and 6th are equal in 

 length and thickness to the 3d ; the 7th is more than twice as wide, triangular, 

 pale yellow, like the preceding joints; the remaining four joints are as wide as the 

 7th, and black. The middle of the anterior margin of the thorax is slightly 

 emarginate, but I suspect this character to be accidental. 



C. alripes, ovata, convcxa, supra testacea (quando viva lostc aurea), thorace antice rotundato, 

 margine hyalino late explanato, angulis externis liaud rotundatis, elytris thorace vix latioribus, 

 humeris paulo productis rotundatis, striis e punctis parcis constitutis, margine hyalino antice 

 declivi postice explanato, vix reflexo, utrinque guttis tribus nigris notatis; subtus nigra, abdomine 

 testacco-marginato, anteunis basi flavis, articulis 3 5 sequalibus, Gto paulo latiore, ultimis 5 

 nigris. Long. -23. 



One specimen, found near Long s Peak. Differs from C. nigripes chiefly by 

 the thorax being nearly as wide as the elytra, with the lateral angles scarcely 

 rounded : the margin of the elytra anteriorly is more obliquely declivous than in 

 that species. 



With regard to the position of C. unipundata Say, I am somewhat doubtful, 

 although to avoid the multiplication of genera it should probably be allowed to 

 remain in Casslda. The 2d joint of the antennre is scarcely thicker than the 3d, 

 which is about twice as long; the 4th is two-thirds as long as the 3d, and some 

 what wider; the 5th is as wide as its length ; and the remaining ones are a little 

 wider than their length: the last is oval and pointed. The ungucs, as in our 

 other species, are simple. 



BRACIIIACATTHA MULS.
