convex laterally, almost but not quite flat suturally ; hind tarsi rather 

 short, stout, the basal joint less than two and one-half times as 

 long as wide. Length (cf) 19.5 mm.; width 6.5 m. Vancouver 

 Island (Victoria) Vancouver! n. sp. 



Form stouter, the head relatively larger, at least three-fourths as wide 

 as the prothorax 4 



4 Size smaller, 1 deep black, shining, the elytra densely alutaceous and 

 rather dull in lustre; head three-fourths as wide as the prothorax, 

 the anterior impressions, as usual, lineiform and deep, the epistoma 

 broadly sinuate from side to side, the labrum broadly, angularly 

 emarginate medially; antennae extending well behind the thoracic 

 base, the first three joints black, the remainder having a brownish 

 tinge; prothorax but little wider than long, the base broadly sinuate 

 medially, two-thirds the maximum width, the latero-basal impressions 

 long and linear, separated by a shining, convex, scarcely depressed 

 surface, the basal marginal stria not extending inward beyond the 

 inner impression; elytra fully a fourth wider than the prothorax, 

 oblong-oval, fully three-fifths longer than wide, feebly convex, with 

 fine and feebly impressed, finely but distinctly punctate striae and 

 nearly flat intervals; hind tarsi rather long, moderately stout, the 

 first joint about three times as long as wide. Length ( 9 ) 23.0 mm. ; 

 width 8.2 mm. Oregon ater Dej. 



Size large, rather stouter, similar in color and lustre; head (cf ) nearly 

 four-fifths, or ( 9 ) three-fourths, as wide as the prothorax, the 

 epistoma feebly, subangularly sinuate from side to side, the labrum 

 rather deeply sinuate in median half; antennae heavy and strongly 

 compressed, nearly one-half longer than the head and mandibles, 

 the latter with broad smooth longitudinal folds medially; prothorax 

 transverse, fully a fourth wider than long, the sides rounded, 

 strongly converging posteriorly, the base two-thirds the maximum 

 width, broadly and feebly sinuate medially, the impressions nearly 

 as in the preceding, except that the intervening surface is a little 

 more depressed though shining; elytra (d 71 ) a sixth wider than the 

 prothorax and nearly three-fifths longer than wide, or ( 9 ) fully 

 a third wider than the prothorax and less than one-half longer 

 than wide, more broadly obtuse at apex but only a little more 

 opaculate, oblong-oval in both sexes, the striae fine, very finely 

 and rather remotely punctate, the intervals flat, feebly convex 

 laterally and distinctly so near the apex; hind tarsi rather long, 

 moderately stout, the basal joint fully three times as long as wide 

 in both sexes. Length (cf) 26.0-28.0, (9) 25.5 mm.; width (c?) 

 9.2-10.0, (9 ) 9-6 mm. California (Lake Tahoe) pollens n. sp. 



5 Mandibles bent inward at apex very obliquely and almost trans- 

 versely, having some long oblique smooth folds medially; coloration 

 and lustre as usual, the elytra a little more opaque; head four- 

 fifths as wide as the prothorax, the impressions not very deep and 

 not sharply defined, the epistoma very feebly sinuate from side 

 to side, the labrum rather deeply sinuate in median half; antennae 

 with the first four joints black, the remainder brownish; prothorax
