behind the thoracic base, similarly colored; prothorax large, almost 

 as long as wide, the sides distinctly crenulate throughout, broadly 

 rounded, feebly converging and straight posteriorly, the angles 

 evidently obtuse though only a little blunt; surface with distinct 

 wavy lines, the inner of the lateral impressions large and deep, the 

 outer also deep but short, bounded externally by a nearly vertical 

 wall; median stria coarse and deep; base feebly sinuate medially, 

 broad, five-sixths the maximum width or even more; elytra two- 

 thirds longer than wide or three-fifths (9 ), a fourth (cf) to a third 

 (9) wider than the prothorax, the striae impunctate, very deep, 

 the intervals very convex throughout, broader and much flatter in 

 the female; hind tibiae (cf) strongly crenulate within except near 

 the base, the tarsi rather long and slender. Length (cT 9 ) 15.8- 

 17.0 mm.; width 5.7-6.0 mm. British Columbia (Metlakatla), 

 Keen herculaneus Mann. 



Form even narrower, deep black, shining, the elytra rather dull in the 

 female; head nearly as in the preceding, the antennae not quite so 

 long; prothorax as long as wide, a little more rounded at the sides 

 and more sinuously narrowed basally, the edges only very finely 

 and obsoletely crenulate, the angles slightly obtuse, blunt, the base 

 broadly sinuate except near the sides, and nearly five-sixths the 

 maximum width, the impressions similar, very deep and conspicuous, 

 the wavy lines obsolete, except those radiating from the median 

 stria, which are short and irregular; elytra nearly two-thirds longer 

 than wide, barely a fourth wider than the prothorax, not very ob- 

 tusely rounded behind, only just visibly wider behind the middle 

 than at base, the striae rather coarse and deeply impressed, impunc- 

 tate, the intervals very moderately convex inwardly, strongly so 

 externally; scutellar stria oblique, long, joining the first stria; 

 humeral denticulation strong. Length ( 9 ) 1 5.5 mm. ; width 5.4 mm. 

 Oregon (Clackamas Co.) pugetanus n. sp. 



Form rather narrow, smaller in size, deep black, polished, the elytra 

 of the female opaculate; head well developed, the anterior impressions 

 unusually large and deep, widely separated, the labrum and epi- 

 stoma sinuato-truncate; antennae rather slender, yellow-brown dis- 

 tally; prothorax only very slightly wider than long, nearly as in 

 the preceding, except that there are no lines radiating from the 

 median stria, the transverse wavy lines evident, the basal angles 

 right and but slightly blunt; lateral edges feebly though rather 

 coarsely crenulate; elytra (cf) three-fifths longer than wide, only 

 very slightly wider behind the middle than at base, with the sides 

 broadly but evidently arcuate, about a third wider than the pro- 

 thorax, the apex evenly rounded and the intervals between the very 

 deep and punctureless striae conspicuously convex throughout, or 

 ( 9 ) broader, much wider behind the middle than at base, with the 

 sides diverging from the base for two-thirds and nearly straight, 

 one-half longer than wide, a third wider than the prothorax, the 

 apex very broadly obtuse and the intervals moderately convex, 

 strongly so laterally; male hind tibiae with a few very broad and
