Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The first abdominal segment in tlie type is large, arcuate at 

 apex and extends slightlj- over the second segment as in the second 

 section of the genus ; it is sparsel}'^ and inconspicuously pubescent, 

 but the apical margin is fringed with a laminate porrect and mem-^ 

 branous border which seems to be split into narrow scale-like 

 pieces. The first four tarsal joints are subequal in length. The 

 se:x of the type is undetermined. 



This species is allied to cas^aneM?n, differing in its rather smaller 

 size, paler color, more slender antennal club, and especially in 

 abdominal structure and in its much shorter and less conspicuous 

 humeral plica and impression. . 



50, C. osculans n. sp— Narrowly suboval, highly polished and impunc- 

 tate, pale flavo-testaceous throughout the body, legs and antennae; pubescence 

 only moderately abundant, coarse, pale, short, even ami recurved on the elytra. 

 Head rather small, but slightly wider than long, broadly rounded at base, the 

 tempora obtusely subangulate; eyes moderately large, slightly prominent, not 

 extending to the middle; antennal prominences strong, rather approximate, 

 separated by a pronounced depression; clypeus even, transversely rectilinear 

 at apex. Antennse slender, longer than the head and prothorax, the club slen- 

 der and very gradual in formation; second joint subcylindric, about % longer 

 than wide, as long as the next two and slightly thicker; three to six equal in 

 width, cylindric; three, four and five equal and quadrate; six perceptibly- 

 shorter, not as long as wide; seventh much larger, % wider and longer than 

 the sixth, not as long as wide, forming an even transition to the eighth, which 

 is % wider than the seventh and nearly as long as wide, conic at apex; ninth 

 and tenth equal in width and nearly }{ wider than the eighth, J^ ^.nd i^' wider 

 than long respectively; eleventh nearly as long as the two preceding and rather 

 thicker, gradually pointed in a slightly oblique ogive. Prothorax conic with 

 feebly arcuate sides, not quite as long as wide; apex ^ as wide as the base, the 

 latter 3^ wider than the head; surface feebly, transversely biimpressed near 

 the basal margin. Elytra % longer than wide, twice as long as the prothorax 

 and nearly ^^ wider, rather acutely rounded at apex, widest only slightly be- 

 fore the middle, the sides rather more strongly arcuate there than toward base 

 and apex; humeral plica narrow but strong and somewhat elongate, the im- 

 pression well marked but small; fovese approximate, rather deep; subsutural 

 impressions distinct, the suture strongly beaded basally, the bead expanded at 

 base. Legs moderate; anterior femora rather strongly, the intermediate less 

 and the posterior feebly, elavate; tarsi slender. Length 0.8 mm. ; width 0.3S 

 mm.
