more slender, the spurs being smaller and less unequal than in the 

 female of calcaratus, the longer one much shorter than the apical 

 width of the tibia. 



The sternal structure is nearly the same as in calcaratus, but the 

 metasternal process is rather less broad, and the mesosternum is 

 more developed behind the middle acetabula. The terminal setae of 

 the prosternal process are about three in number, extremely short, 

 being much shorter than in calcaratus. 



This species is widely distributed, and differs from the preceding 

 in its larger size, black color, more convex form, finer elytral sculp- 

 ture and punctuation, more especially in the rows toward the suture, 

 and, more decidedly, in the greater dilatation and obliquity of trun- 

 cation of the posterior tibiae in the male. It varies considerably in 

 size. 



At piceilS n. sp. — Broadly oval, rather pale fusco-piceous above, very pale 

 brownish-flavate throughout beneath, polished, the elytra feebly alutaceoua, 

 moderately convex ; sides feebly convergent behind frona the base of the elytra. 

 Head not reticulate, extremely finely and feebly punctate ; eyes moderate ; 

 apical margin of the front witli two minute fovese on each side just above the 

 insertion of the antennae, the latter rather slender, the third joint distinctly 

 shorter than the next two together ; club elongate, very slender, symmetrical, 

 parallel and rather loose ; ninth joint slightly longer than wide and a little 

 longer tlian the tenth, the latter nearly as long as wide and not wider than 

 the ninth, the eleventh elongate, nearly as long as the" two preceding, obtusely 

 rounded at the apex, without trace of terminal process. Prothorax between 

 two and three times as wide as long, very strongly narrowed from base to 

 apex ; basal lobe very feeble, the bead strong but very short, not extending 

 laterally beyond the lobe ; disk with feeble traces of transverse reticulation 

 toward base ; punctures almost obsolete. Scutellum scarcely wider tlian long, 

 ogival, with the sides slightly arcuate. Elytra rather short, about two and 

 one-half times as long as the prothorax, evenly and not very broadly rounded 

 at apex ; surface very minutely and rather strongly transversely strigilate in 

 wavy lines throughout, except near the base, where the sculpture becomes very 

 feeble, having series of small transversely crescentiform punctures, which are 

 feebly impressed and which are not much wider or more distinct toward the 

 sides, the seri(!S accompanied by fine feebly impressed lines, the intervals with 

 uneven series of excessively minute feeble punctures of the same nature ; all 

 the punctures becoming gradually obsolete in basal third ; discal stria fine but 

 distinct, obsolete at basal third. Length 1.9 mm. 



District of Columbia. Mr. Ulke. 



The description is drawn from the male, the posterior tibiae being 

 gradually strongly dilated from base to apex and very obliquely 

 truncate, the spurs long and very unequal, the posterior tarsi long
