not paler at tip^ the legs pale, the anteoDae dusky testaceous, the elytra 

 translucent, pale fiavate, gradually blackish toward base; head bat 

 slightly elongate, gradually broader to the rather narrowly rounded 

 basal angles, the sides just visibly arcuate, the punctures not very 

 coarse but deep, moderately close-set, wanting along the middle as 

 usual; post-ocular flattened line distinct, closely and confusedly punc- 

 tate, the punctures of the under surface small but strong, sparsely 

 distributed, obsolescent basally; prothoraz elongate, slightly narrower 

 than the head, the dorsal series of 10-12 moderate, rather close -set 

 punctures, the sublateral long and of nearly as many, with some 

 others externally and anteriorly; sides distinctly converging and 

 straight, the angles not very broadly rounded; elytra elongate, barely 

 as long as the prothorax but evidently wider, the punctures numerous, 

 broadly confused toward the suture, more or less lineate thence to the 

 lower margin of the flanks, the first series deepest and most regular; 

 abdomen at base much narrower than the elytra, gradually broadening 

 behind, finely, sparsely punctulate. Length 4.7-5.0 mm. ; width 0.75-0.8

Body 8mall, slender, convex, polished, deep black throughout, the elytra 

 scarcely visibly plcescent; legs very dark rufous, the antennae blackish; 

 head formed nearly as In Jlavipes but smaller and with rather more 

 broadly rounded basal angles, the punctures strong and deep, though 

 only moderately coarse and somewhat sparse toward the sides, almost 

 equally strong beneath, tending to form two longitudinal series at each 

 side, very inconspicuous medially and basally, the post-ocular flattened 

 line blserially and rather strongly punctate ; prothorax slightly elongate, 

 fully as wide as the head, with the apical angles v^ry broadly rounded t 

 the sides thence moderately converging and nearly straight posteriorly; 

 punctures of the dorsal series 8-10 in number, not very coarse but 

 distinct, rather less numerous in the sublateral series, with a few Iso- 

 lated near the apical angles as usual; elytra elongate, longer and much 

 wider than the prothorax, the punctures rather tine but distinct, forming 

 equidistant and subeven series throughout the width, except very near 

 the suture, the series on the upper convexity of the flanks usually most 

 close -set; abdomen slightly narrower than the elytra, parallel, sparsely 

 and feebly punctulate. Length 3.6-3.9 mm.; width 0.65-0.68 mm.

 highly polished throughout, the head black; abdomen very dark, the 

 entire elytra paler, piceous, the prothorax and legs pale testaceous, the 

 antennae darker, rufous; head well developed, slightly elongate, grad-

 and the angles broadly rounded ; punctures coarse and deep, somewhat 

 close laterally, smaller but distinct and sparsely scattered on the under 

 surface, which becomes Impunctate toward the suture posteriorly and
