third discal stria extending nearly to apical fourth; abdomen sh'ghtly 

 shorter than the elytra and not quite as wide, the first dorsal 

 impressed and puberulent at base ; ventral sexual characters of the 

 male simple, the sixth segment feebly tumid laterally. Length, 2.0 

 mm.; width, 0.8 mm. British Columbia (Metlakatla), J. H. Keen, 

 and Vancouver Island Keefii, n. sp. 



8. Larger species, some 2 mm. in length, the head unusually small, very 



much narrower than the prothorax; basal impression of the abdomen 

 wider, about half the total width. Vancouver Island . . striates, Lee. 



Smaller species, the head larger, though evidently narrower than the 

 prothorax ; basal impression of the abdomen narrower, evidently 

 less than one-half the total width, and more strongly bilobed. 

 California (Humboldt to Sonoma) abbreviatus, Csy. 



9. Antennal club very stout, the two penultimate joints strongly trans- 



verse 10 



Antennal club more slender, the penultimate joints very moderately 

 transverse 11 



10. Species of the Sierras, the head small, very much narrower than the 

 prothorax; second elytral stria broadly amalgamating with the sutural 

 stria near apical third. California (Placer Co.) mo7itanus, Csy. 



Species of the northern coast regions, larger in size, the second stria 

 free throughout ; head moderately small though very obviously 

 narrower than the prothorax, the eyes moderate, though a little more 

 prominent, evenly castaneo testaceous, polished, moderately convex, 

 the pubescence rather sparse and inconspicuous ; prothorax a little 

 wider than long, of the usual form, finely, sparsely perforato- 

 punctate, the lateral teeth small and rather obtuse ; elytra more 

 strongly, though sparsely and more rugusely punctate ; elytra 

 transverse, one-half longer and v/ider than the prothorax, the sides 

 strongly diverging and broadly arcuate from base to apex, the 

 elongate humeral callus strong ; abdomen with unusually arcuate 

 sides, as wide as the elytra and much longer, the basal impression 

 nearly one-half the total width. Length, 2.0 mm.; width, 0.72 mm. 

 British Columbia (Metlakatla), Keen brevipejmis, n. sp. 



1 T. Last two joints of the antennal funicle shorter than the preceding, 

 though scarcely at all broader, strongly transverse, the club about as 

 long as the preceding six joints combined, with unusually little
