head, excepting the antennoe, 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. 



CASSIDA Linn. 



C. ellipsis, elliptica couvexa, supra testacea pallida, nitida (quando viva, laete aiirea), tliorace 

 antice rotuiidato, margiue late explanato h3'aliiio, aiigulis lateralibus paulo rotundatis, elytris 

 thorace liaud latioribus, fortius striato-punctatis, margiue sublijalino, antice declivi postice ex- 

 planato angustius reflexo, capita corporeque nigris, abdomiue anguste testaceo marginato, pedibus 

 antennisque flavis, his articulis 3 — 6 teuuibus aiqualibus, 7 — 11 latioribus, ultimis quatuor nigris. 

 Loug. '26. 



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

 explanate but narrowly reflexed elytral margin, to C. 6-punc(afa and C. d-maculata, 

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

 C d-maciilafa are black ; in C. Q-jmndata they are reddish yellow, but the punc- 

 tures of the stria3 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 antenna) : 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 Gth 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 tliorax is slightly 

 emarginate, but I suspect this character to be accidental. 



C. atripes, ovata, eonvexa, supra testacea (quaudo viva la'^te anrea), tliorace antice rotundato, 

 margiue hyaline late explanato, angulis externis haud rotundatis, elytris thorace vix latioriljus, 

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

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

 testaceo-marginato, antennis basi flavis, articulis 3 — 5 ajqualibus, Cto 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 Cassida. The 2d joint of the antenna? 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 ungues, as in our 

 other species, are simple.
