first two, subequal among themselves, joints five to ten broader than the preceding 

 two and shorter, gradually but slightly increasing in width, eleventh slightly longer 

 than the penultimate. Prothorax wider at base than apex, sides arcuately narrowing 

 to apex, base lobed at middle, the lobe before the scutellum very slightly emarginate, 

 posterior angles very slightly prolonged behind, apex truncate, front angles prominent 

 acute; disk convex in front, at sides near front angles depressed, extremely finely 

 punctate, intermixed with sparsely placed larger punctures. Scutellum distinct nar- 

 rower behind, very finely punctate. Elytra at base as wide as the thorax, sides 

 nearly parallel, narrowing slightly towards apex, which is gradually rounded and 

 acute at apex ; disk feebly convex finely punctate with larger punctures intermixed. 

 Underside finely and densely punctate, finely pubescent. Length, 2-2.25 mm.

This fine species is dedicated to Mr. E. A. Schwarz as a slight 

 recognition of the many favors received, while on a visit to Wash- 

 ington. Differs from crotchii \x\ the much finer, shorter pubescence 

 and more subopaque surface, the distinct seven-jointed club, pale legs, 

 as well as being not as convex. From Casey's politiis the greenish 

 piceous, subalutaceous surface, the seven-jointed antennal club and 

 the different punctuation of elytra will readily separate it. The follow- 

 ing table based on the differences mentioned above will help in 

 separating our three species. 



Pubescence of upper surface consisting of very fine and short hairs, body above sub- 

 opaque antennae with first four joints pale, the seven-jointed club \A2izV...schzvarzii. 

 Pubescence of upper surface consisting of coarser and longer hairs, antennse black, 

 club six-jointed, body above shining. 



Third and fourth joint of antenna; subequal ciotclni. 



Third joint of antennse longer than the fourth, almost as long as the fourth and 

 fifth together politus. 



Cinyra prosternalis, new species. 



Elongate, cupreous, thorax with at most a faint longitudinal median impression. 

 Head asneous, coarsely punctured, denser in the clypeal region ; anlenn;e metallic 

 green, not quite as long as the head and prothorax ; clypeus broadly emarginate ; 

 front with an impunctured inverted W-like design. Thorax broader at base than 

 apex, with sharp hind angles, a faint longitudinal median impression, and one broad 

 shallow impression on each side of base ; moderately coarsely punctate, sparsely at 

 middle, more densely and in some parts confluently at sides. Elytra about three tmies 

 as long as the thorax, apex quadrispinose, intervals sparsely and more finely punctate, 

 alternate intervals more convex towards apex. Pro^ternum smooth and shining, in 

 some specimens extremely finely punctate, at sides very coarsely and transversely con-
