Corimelteiia nigra Dallas. 



This species, as I have located it, is broader and siiorter than 

 nitiduloides ; the punctures are stronger and ch)ser, leaving the 

 surface more opaque; the pronotuni and l)ase of the scutelluni are 

 transversely wrinkled ; there is a well-defined smooth area occupy- 

 ing the position of* the callosities; the base of the scutelluni is more 

 deej)ly excavated on either side, and above this the sui-face is more 

 strongly impressed. 



In July of last year I swept three examples of this sj)ecies from 

 the dry prairies about Fort Collins, Colo. Another specimen, re- 

 ceived some years ago from a correspondent in Canada, is more 

 strongly punctured and wrinkled and is slightly tinged with i)ur- 

 ple above. 

 Corinielteiia aiitliracina Uhler. 



Under this name I have placed a species from Vancouver Island, 

 of which I have received two specimens from Rev. G. W. Taylor, 

 and have seen others taken by Prof. F. H. Snow in New Mexico, 

 and by Prof. x\ldrich in Idaho. In form these most resemble uni- 

 color, but they are smaller and more convex above, and the punc- 

 tures are stronger and more uniformly distributed even than in 

 nitidaloides. Tliey may be best distinguished from their nearest 

 relatives by the sides of the pronotuni, which are more vertical, with 

 the narrow reHexed margin abbreviated before the tumid impunc 

 tured humeri. In the prominent humeri and the style of [)unctuati()n 

 this species approaches nigra, but the broadly ovate form of the 

 latter will at once separate them. 



CurinieltPiia ciliata Uliler. 



This species is even shorter and broader than nigra, being almost 

 hemispherical, but a little angularly produced before. The upper 

 surface is opaque, deep black with a tinge of purple. It is very 

 closely and deeply punctured and quite distinctly transversely 

 wrinkled on the disk of the j)r()notum and scutelluni. The fringe 

 of conspicuous cilise about the body and the short and broad corium 

 are other characters that will serve to distinguish this species. 



In July, 1908, I took one example of this very distinct specie.s 

 on the dry prairies, near the Leyden coal mines, just west of Den- 

 ver, Colo. Another specimen was kindly presented to me by Prof. 

 F. II. Snow, who took it in Morton County, Kan., and Mrs. 

 Slossou has sent me an examj)le taken at Lake Worth, Fla.
