head ; surface strongly, transversely impressed near the base, the impression 

 not definitely interrupted at the middle. Elytra % longer than wide, evenly 

 oval, narrowly rounded at apex, much more than twice as long as the pro- 

 thorax and very nearly twice as wide, widest at basal %; sides broadly 

 arcuate ; humeral plica distinct and moderatly long, the attendant impression 

 moderate in size but deep at base ; foveee distinct ; subsutural impressions 

 very conspicuous, the suture strongly beaded basally, the bead strongly ex- 

 panded at base. Abdomen with the first segment widely overlapping the next 

 and having a deep pale coriaceous hind margin. Legs well developed, the 

 femora moderately clavate. Length 1.4 mm. ; width 0.6 mm. 



Pennsylvania (locality unknown). 



This species, which is represented by the female only, is some- 

 what similar in appearance to nigrum and atrum, but differs from 

 both in its smaller size and distinctly transverse penultimate 

 joint of the antennae; the subhumeral impression is nearly as in 

 nigrum, and is decidedl}'^ less developed than in atrum ; the head 

 is relatively wider, more broadly rounded at base and with some- 

 what larger ej'es than in nigrum. 



81. C limatum n. sp. — Not very stout, highly polished and impunctate, 

 dark rufo-testaceous, the antennae concolorous; elytra blackish-pi ceous through- 

 out, paler at apex from diaphaneity ; legs dark red -brown, the tarsi flavate; 

 pubescence abundant, long, erect and pale on the elytra. Head slightly wider 

 than long, parabolic behind, the eyes quite large, prominent and conspicuous ; 

 antennal prominences feeble, the front feebly impressed ; clypeus slighty ru- 

 gose, rectilinear at apex, with a very minute, broadly triangular and incon- 

 spicuous median projection. Antennae barely 3^2 ^s long as the body, the club 

 rather narrow and somewhat gradual in formation but distinct ; second joint 

 stout, feebly obconic, % longer than wide, as long as the next two and much 

 thicker ; three to six equal in width ; third distinctly shorter than wide ; 

 fourth and sixth as long as wide ; fifth slightly longer ; seventh fully }ii wider, 

 with a fine basal bead, }4 wider than long ; eighth fully % wider than the 

 seventh, as long as wide ; ninth and tenth very nearly equal, a little wider 

 than the eighth, scarcely ]4 wider than long ; eleventh somewhat thicker, 

 long, very gradually, obliquely and finely pointed, fully as long as the two 

 preceding. Prothorax well developed, scarcely as long as wide, conic ; apex 

 about y^ as wide as the base, the latter nearly % wider than tiie head ; sur- 

 face strongly impressed transversely near the base, the impression scarcely in- 

 terrupted. Elytra rather long, oval, widest only slightly before the middle, 

 narrow at apex, % longer than wide, distinctly more than twice as long as the 

 prothorax and about %_ wider ; sides broadly, evenly arcuate ; humeral plica 

 long and strong, the impression large and deep ; fovese deep ; subsutural im- 

 pressions very long and rather vague, the suture strongly beaded basally, the 

 bead expanded at base. Abdomen with the first segment overlapping the next 

 and fringed with a deep porrect submembranous border at apex. Legs long ; 

 femora rather strongly clavate, especially the anterior. Length 1.5 mm.; 

 width 0.65 mm.
