Coleopterologiral Notices, V. 567 



ing mncli beyond apical third. Pygidia strongly, moderately coarsely, very 

 densely punctate. Prosternum strongly convex but not compressed, the striae 

 rapidly and strongly ascending ; latero-snbapical fovese small but deep, well 

 defined; sides of the mesosternum strongly convergent ; apical stria entire. 

 Anterior tibiae triangular, not very wide, finely but strongly, rather closely 

 serrulo-spinose externally. Length 1.9-2.7 mm. ; width 1.4-1.9 mm. 



Utah (southwestern). Mr. Weidt. 



To be associated with covvexiusculvs and minvUts, resembling 

 the former in its long dorsal striae but differing in the disposition of 

 the eljtral punctured areas; from minutus it differs in its much 

 longer dorsal striae. Two specimens, differing greatly in size. 



S. lentils. — Oval, strongly convex, highly polished, black with pronounced 

 seneons lustre ; legs rufescent. Head minutely but strongly, closely punctate, 

 with a small but distinct puncture in the middle near the base ; marginal striae 

 obsolete above the eyes. Prothorax a little more than twice as wide as long, 

 the sides strongly convergent, broadly, evenly arcuate from base to apex ; 

 apical angles narrowly rounded ; marginal stria distinct ; disk very minutely, 

 sparsely punctulate, gradually more closely anteriorly, abruptly coarsely and 

 xery densely punctate near the sides and narrowly along the basal margin. 

 Elytra not quite twice as long as the prothorax, and, at basal fourth, much 

 wider, extremely, minutely, sparsely punctulate, somewhat abruptly, rather 

 coarsely and densely punctate behind, from basal two-fifths near the first 

 dorsal, to apical two- fifths near the suture ; marginal stria deep, inferior, nearly 

 straight ; outer subhumeral distinct, separated from the marginal ; oblique 

 liumeral coarse and deep, continued at some distance behind by the inner sub- 

 humeral, which is short and feeble ; dorsals coarse, the first and third equal, 

 extending nearly to apical two-fifths, second and fourth equal but slightly 

 shorter, the latter broadly arched at base joining the entire sutural ; trans- 

 verse apical stria nearly attaining the suture. Pyyidia finely but deeply, 

 densely and evenly punctate. Prosternum evenly convex, the striae distinct, 

 rapidly ascending, the foveae deep ; mesosternum finely punctate, sparsely in 

 the middle ; apical stria entire, transverse ; suture crenato-punctate. Ante- 

 rior tibiae with about seven long and very acute, anteriorly inclined, serriform 

 teeth. Length 3.5 mm. width 2.5 mm. 



California (Truckee — elevation 6000 ft.). 



Allied somewhat to insertus, but diff'ering altogether in the punc- 

 tuation of the pronotum and elytra, and in the widely distant and 

 isolated external subhumeral stria. 



S. opacellllS. — Oval, strongly convex, deep black, dull or feebly shin- 

 ing. Head rather finely but strongly, very densely punctate, without trace 

 of the subbasal puncture ; marginal stria obsolete, not distinct even subapi- 

 cally. Prothorax twice as wide as long, trapezoidal ; sides moderately arcuate, 

 visibly more so toward apex ; marginal stria fine ; punctures not very coarse
