HARPALIN.E 251 



(cf 9 ) 3.4-3.6 mm.; width 1.2-1.25 mm. California (Redwood 



Creek, Humboldt Co.). Two examples lustrellus n. sp. 



Upper surface not uniform and deep black throughout 16 



16 Elytra black, with only the suture rufescent 17 



Elytra black with the suture and long humeral nubilous area rufescent. 1 8 

 Elytra testaceous, each blackish toward but not across the suture. ... 19 

 17 Bod y elongate, only moderately convex, shining, black, the prothorax 

 more piceous-black as a rule and usually pallescent apically and 

 basally, the sutural interval of the elytra rufescent; under surface 

 piceous-black; legs pale flavo-testaceous to piceo-testaceous; head 

 three-fourths as wide as the prothorax, the eyes only very moderate 

 in size and slightly prominent; antennae slender, dusky, the three 

 basal joints pale- prothorax short and transverse, two-fifths wider 

 than long, the sides strongly rounded anteriorly, oblique and nearly 

 straight posteriorly, the angles obtuse but sharply marked, though 

 the apices are scarcely at all prominent; base subequal in width to 

 the apex; surface with a strong entire stria, generally feeble and 

 sparsely punctulate anterior transverse impression and broadly 

 flattened or feebly impressed, closely, strongly and very conspicuously 

 punctured latero-basal areas, the punctures ascending along the sides 

 to some extent; lateral part of the surface anteriorly with fine sparse 

 punctulation, distinct in the type but obsolete in some individuals; 

 elytra one-half longer than wide, but little more than a third wider 

 than the prothorax, parallel, with feebly arcuate sides; striae deeply 

 impressed; intervals strongly convex suturally, less so externally and 

 apically, the discal puncture at or behind two-thirds. Length 

 (cf 9 ) 3.3-3.9 mm.; width 1.15-1.35 mm. California (San Fran- 

 cisco Bay and northward in the coast regions). Ten examples. 



puncticollis n. sp. 



Body larger and broader than in the preceding, otherwise somewhat 

 similar in general habitus, but with paler prothorax, black, shining, 

 the elytra black, with pale suture when mature, sometimes mostly 

 testaceous, the pronotum piceo-testaceous, clouded slightly with 

 darker tint toward the sides; under surface black, the legs and epi- 

 pleura piceo-testaceous; head nearly as in puncticollis. but more 

 elongate, the antennae slender but shorter, blackish, the two basal 

 joints pallid; prothorax similar in its short transverse outline and 

 form of the basal angles, but with the latero-basal area broadly, 

 feebly impressed and very minutely punctate, the punctures not 

 extending along the sides, the entire remainder of the surface 

 impunctate, the stria fine, not attaining the apex; elytra broader, 

 barely one-half longer than wide, one-half wider than the prothorax, 

 similarly striate and with convex intervals. Length (9) 3.7-4.0 

 mm.; width 1.35-1.4 mm. California (Truckee 6000 feet eleva- 

 tion, in the Sierras). Two specimens montanus n. sp. 



Body much smaller than in either of the two preceding, shining, black, 

 the pronotum pallescent apically and basally, the elytral suture 

 pale; under surface black, with pale hypomera and epipleura, the 

 legs very pale flavo-testaceous; head moderate, the eyes rather small 

 but prominent; antennae slender, rather more than half as long as the
