BEMBIDIIN^E 91 



sharp; surface nearly similar; elytra fully one-half longer than wide, 

 parallel, with feebly arcuate sides, less obtusely rounded at apex, 

 nearly two-fifths wider than the prothorax; striation similar, the 

 punctures sometimes notably coarser basally. Length ( 9 ) 4.2-4.4 

 mm.; width 1.55 mm. California (Siskiyou Co.), Koebele. 



continens n. sp. 



5 Surface moderately convex, rather shining, slightly alutaceous an- 

 teriorly, deep black, sometimes feebly aeneous; head three-fourths 

 as wide as the prothorax and fully as wide as an elytron, with rather 

 prominent eyes; antennae rather long, the medial joints between 

 two and three times as long as wide; prothorax one-half wider than 

 long and much narrower than the elytra, the sides evenly, rather 

 strongly rounded, oblique in about basal half, becoming slightly 

 though evidently sinuate toward the angles; margins not broadly 

 but strongly reflexed; impressions very feeble, the moderate stria 

 incomplete; fovese small, deep, sublinear, the carina long and strong, 

 distant from the fovese as in all the preceding species; elytra fully 

 one-half longer than wide, about two-fifths wider than the pro- 

 thorax, gradually parabolic behind, parallel, with broadly arcuate 

 sides, the striae fine, entire, scarcely at all impressed, the seventh 

 feebler than the others; punctures fine, close-set, sometimes rather 

 stronger basally; foveae normally small, before basal and near apical 

 third. The elytra are generally deep black throughout, but in one 

 example there is a minute feeble and barely discoverable pale point 

 externally near apex and another just outside the middle of the 

 disk near basal fourth. Length (c? 9 ) 4.2-4.7 mm.; width 1.5 

 1.75 mm.; Vancouver Island (Victoria) and Washington State. 



imperitum n.sp. 



Surface of the elytra more polished and rather more convex, the dorsal 

 foveae larger and conspicuous, deep black throughout, feebly alu- 

 taceous anteriorly, the elytra without trace of pallid maculation; 

 head rather larger but otherwise similar, distinctly wider than an 

 elytron, the antennae similar; prothorax throughout nearly as in 

 imperitum, one-half wider than long and with the oblique sides 

 basally barely distinguishably sinuate before the angles, which are 

 sharp and nearly right, but the carina is about as long as the fovea 

 and not much longer as it is in that species; elytra rather shorter, 

 broader and more convex, scarcely one-half longer than wide, a third 

 wider than the prothorax; striae entire, not so fine and distinctly im- 

 pressed, the punqtures a little coarser, similarly close-set and gradually 

 obsolete behind; second and fifth striae similarly grooved at tip; 

 foveae similarly placed but larger and stronger, not impressed but 

 abruptly outlined. Length (cf 1 ) 4.4 mm.; width 1.5 mm. Wash- 

 ington State prociduum n. sp. 



6 Body oblong, rather convex, black, alutaceous anteriorly, the under 

 surface and epipleura black; elytra with a small pale point at the 

 base of the fifth interval, two similarly small on the third interval 

 before and behind basal third, a fascia near basal third, broad on the 

 margin, becoming rapidly attenuate inward and ending on the fifth 

 interval, an entire biarcuate irregular fascia near apical third and
