HARPALIN^E 229 



puncture at three-fifths, the scutellar stria obsolete as usual; hind 

 tarsi very slender, black. Length (cf) 4.1 mm.; width 1.7 mm. 

 Queen Charlotte Islands, Keen boreellus n. sp. 



Color piceous-black, the prothorax nubilously paler apically and basally; 

 elytra black, broadly, nubilously paler basally and along the suture; 

 under surface black, the epipleura pallescent, the legs entirely or in 

 in great part pale; general habitus nearly as in cognatus Gyll.; surface 

 shining in both sexes; head with scattered punctures near the oblique 

 foveae and at base, three-fourths as wide as the prothorax, the eyes 

 prominent; antennae rather long, slender, piceous-black, with pale 

 basal joint; prothorax nearly as in the preceding but more transverse, 

 more than one-half wider than long, the sides more broadly rounded, 

 the basal angles equally obtuse but rather more blunt, not so distinctly 

 defined, the surface nearly similar but with less distinct punctuation; 

 elytra narrower and more parallel than in the preceding though 

 nearly similar in general form and striation, the fine punctulation 

 more distinct and less sparse, visible though nearly the two outer 

 intervals and more broadly apically, also slightly visible at base; 

 hind tarsi similarly very slender and moderate in length. Length 

 (of 1 9 ) 3.8-4.3 mm.; width 1.4-1.7 mm. British Columbia (Metla- 

 katla) to Labrador and southwardly along the Rocky Mountains to 

 New Mexico (Cloudcroft), Knaus. Abundant. [Acupalpus ax fi- 

 lar is, longiusculus and con fla grains Mann.]. Twenty examples.

Color pale tawny-yellow throughout, the elytra sometimes very inde- 

 finitely and feebly infumate discally, the legs pale testaceous; surface 

 shining in both sexes; head nearly as in the preceding, finely punc- 

 tulate basally but with barely any punctures near the oblique and 

 deep fovese; antennae slender, very pale brown, paler at base; pro- 

 thorax nearly as in ruficrus and similarly transverse but with larger 

 and more irregularly impressed foveae, the punctulation apically and 

 basally fine but evident; elytra much larger and longer, distinctly 

 widest behind the middle, with arcuate sides and obtusely rounded 

 apex, one-half longer than wide and nearly one-half wider than the 

 prothorax; striae very fine and rather feebly impressed, the intervals 

 flat, the discal puncture usually but little behind the middle; minute 

 punctulation sparse, extending a little further from the lateral, basal 

 and apical edges than in ruficrus, though seldom pervading the upper 

 part of the surface; hind tarsi very slender, the basal joint subequal 

 to the next two combined. Length (cf 9 ) 3-84.3 mm.; width 1.5 

 1.8 mm. California (San Francisco to San Diego). [Bradycellus 

 nitens Lee.] nitens Lee. 



4 Minute punctulation extending about half way across the elytra 

 medially, very broadly distributed basally and apically. Color 

 pale testaceous, the head largely blackish, the pronotum with a small 

 quadrate central black spot; each elytron narrowly and nubilously 

 clouded with blackish toward the suture, excepting the sutural 

 interval, this black area extending only a little before the middle and 

 not attaining the apex; surface very shining; legs pale testaceous; 

 head nearly as in nitens but with stronger punctulation near the
