fifths as long as the latter, the punctures asperate and moderately strong 

 but not very close-set; ablomea at base scarcely as wide as the elytra, 

 only moderately narrowed thence to the tip; basal joint of the hind 

 tarsi rather longer than the next two combined, joints iwo to four equal, 

 the tarsus distinctly shorter than the tibia. Length 3.5 ram.; wi.lth

gleiutraiia n. sp. 

 Mesosternal carina less abbreviated, not attaining the tip of tae process by 



about the apical width of the latter, and sometimes much less 6 



€ — Elytra evidently much longer than the prothorax 7 



Elytra about equal in length to the prothorax or at least not conspicuously 



longer, the form more elongate, parallel and linear 8 



7 — Head small, half as wide as the prothorax, the sides of the latter strongly 

 converging and evenly, moderately arcuate from base to apex; anten- 

 nae longer and less incrassate, longer than the head and prothorax, the 

 tenth joint le-^s than one-half wider than long, the second and third 

 elongate and subeqaal. Body only moderately stout, more parallel than 

 in rotundicoUis, polished, black, the elytra dark piceo-rufous, the legs 

 dark piceous, the antennae blackish, not distinctly paler at base; head 

 and prothorax finely, sparsely punctulate, the latter less transverse 

 than usual, scarcely one-half wider than long, the pubescence very fine, 

 sparse and inconspicuous; elytra parallel, scarcely wider but evidently 

 longer than the prothorax, the suture about as long as the latter, the 

 punctures fine, unusually feeble and widely separated, not at all dense; 

 abdomen at base nearly as wide as the elytra, moderately narrowed 

 thence to the apex, very finely and sparsely punctate, polished; hind 

 tarsi almost as long as the tibiae, the basal joiat as long as the next two 

 combined. Length 3.2-3.8 mm.; width 0.82-1.0 mm. California (San 



Francisco to Humboldt Co.) UYidula n. sp. 



Head larger, three-fifths as wide as the prothorax, the sides of the latter 

 very feebly converging from base to apex and more rounded ; antennae 

 shorter, more compact and incrassate, as long as the head and protho- 

 rax, the tenth joint nearly twice as wide as long, the second and third 

 elongate, the former slightly the shorter. Body slightly stouter, less 

 parallel, shining, piceous, the abdomen black, the elytra piceo-rufous; 

 antennae black, piceous at base, the legs paler, piceous; head and pro- 

 notum minutely, sparsely, the latter less sparsely, punctate, the eyes 

 rather distant from the base ; prothorax small, one-half wider than long^ 

 strongly rounded at base, the disk with two feeble approximate longi- 

 tudinal impressions toward base; elytra large, much wider as well as 

 longer than the prothorax, the suture slightly longer than the median 

 line of the latter, the punctures fine, asperulate and close-set, much less 

 separated than in the preceding species; abdomen at base distinctly 

 narrower than the elytra, moderately tapering, very finely, sparsely 

 punctured ; hind tarsi somewhat shorter than in uvidula. Length 3.4 



mm.; width 1.0 mm. Queen Charlotte Island rotnndicollis n. sp. 



Head rather more than half as wide as the prothorax, the latter transversely 

 elliptical, with the sides only just visibly converging from base to 

 apex and strongly, evenly arcuate; antennae very well developed, grad- 

 ually and strongly incrassate to the tip, the tenth joint less than twice as
