abdomen elongate, parallel, nearly as wide as the elytra; raesosterual 

 process only moderate in width, the carina stronger than in the pre- 

 ceeding groups and similar to the following, the metasteraal process 

 Tery short, broadly parabolic; hind tarsi much shorter than the tibiae, 

 the basal joint as long as the next two combined. Length 3.2-4.5 mm ; 

 width 0.7-0.9 mm. British Columbia (Kamloops and Glenora), — H. F.

Abdominal impressions unusually large, deep and extremely coarsely, sub- 

 conflaently punctate, the remaining part finely, closely punctate but 

 polished. Body stouter, linear, parallel, black, the elytra scarcely 

 visibly paler, piceous, the legs blackish-piceous, the antennae black, 

 but little paler at base ; vestiture fine, short, decumbent, close but not 

 Tery conspicuous; punctures of the head and pronotum very flae, ex- 

 tremely cloie-set on the latter, less so on the former, flue, asperate and 

 very dense on the elytra; head half as wide as the prothorax; antennae 

 somewhat longer than the head and prothorax, rather stout, gradually 

 incrassate to the tip, the second joint shorter than the third; prothorax 

 transversely suboval, not much narrowed from base to apex and strongly 

 rounded at the sides; elytra transverse, slightly shorter and evidently 

 wider than the prothorax, the suture fully two-thirds as loag, the apical 

 margin finely rufescent; mesosSernal process moderately wide but not 

 extending to the posterior limits of the coxae, the metisternal process 

 longer than usual, narrowly rounded under the tip of the mesosternal 

 process, with its margins thickened and much elevated; hind tarsi 

 much shorter than the tibiae, which are unusually finely and closely 

 pubescent, the basal joint long, distinctly longer than the next two 

 combined. Length 3.7-4.4 mm; width 0.85-1.06 mm. New York

12 — Moderately stout, sublinear, polished, convex, deep black, the elytra 

 not distinctly paler, each with a small rufous spot at apex near the 

 suture; legs blackish-piceous, the antennae black, somewhat piceous at 

 base ; vestiture moderately distinct, rather sparse, decumbent ; punctures 

 of the head very fine and remote, of the pronotum nearly as fine and 

 notably sparse, of the elytra fine but rather strongly asperate and close- 

 set, of the abdomen ftae and somewhat close-set throughout, the punc- 

 tures evenly in quiacunx order and joined anteriorly and posteriorly by 

 fine lines, forming a regular imbricate sculpture; head fully as long as 

 wide, not quite half as wide as the prothorax, the antennae unusually 

 slender, attaining the middle of the elytra, the tenth joint only very 

 slightly wider than long, the eleventh longer than the two preceding 

 combined, the second much elongated and — very exceptionally in the 

 genus — slightly longer than the third; prothorax transversely suboval, 

 strongly narrowed from base to apex, the sides only moderately arcuate, 

 the base broadly rounded; elytra slightly longer than the prothorax 

 and about equally wide, the suture equal thereto in length ; abdomen 

 long, parallel, not quite as wide as the elytra, the impressions normal; 

 mesosternal process unusually wide, normal in length, the metasternal 

 process broad and very obtuse; hind tarsi short, v«ry much shorter 

 than the tibiae, which are more slender and more coarsely and sparsely
