512 CASEY 



prothoiax, with the somewhat prominexit and angulate humeri 

 widely and onl}^ a little obliquely exposed at base, the sides par- 

 allel and broadly arcuate, the apex rather gradually ogival, with 

 the individual angles acute, prominent and everted ; surface with 

 only slightly elevated, even series of short and close-set carinas, the 

 alternate series more prominent toward base, the intervals with 

 single series of somewhat coarse and perforate, moderately close- 

 set tuberculiferous punctures, the suture narrowly margined with 

 unevenly rugose carinules ; abdomen only moderately coarsely 

 and not ver}' closely punctured medially, except at base. Length 

 14. 0-15.0 mm. ; width 4.8-4.9 mm. California (Oakland) . 



aequicoUis Esch. 



Body nearly as in <^quicollis but somewhat smaller and less stout, 

 black, similar in lustre and in the short sparse hairs ; head before 

 the eyes less abruptly, more feebly prominent and thence less 

 strongly converging and more arcuate to the apex, almost simi- 

 larly sculptured ; antenuce with the third joint very distinctly 

 longer than the fourth; prothorax nearly similar in form and 

 sculpture though much less dilated anteriorly, the sides less con- 

 verging toward base and less reflexed, almost as long as wide ; 

 elytra nearly as in cequicollis in form and sculpture, except that 

 the humeri are but little exposed at base, and the surface at each 

 side of the suture is more finely, confusedly tuberculose and 

 less differentiated from the first series of punctures, the alternate 

 series of carinules scarcely perceptibly more prominent toward 

 base ; abdomen, for the present genus, rather finely and notably 

 sparsely punctate toward the middle and not densely so even on 

 the first segment. Length 13.7 nmi.; width 4.4-4.^5 mm. Cali- 

 fornia (Truckee) maura n. sp. 



Body smaller than in the two preceding and more slender, brownish- 

 black or paler, slightly shining; head nearly as in cequicollis^ the 

 oblique sides anteriorly strongly converging and nearly straight, 

 the basally very coarse sculpture becoming very gradually and 

 only slightly less coarse anteriorl}'^, and not abruptly so and ma- 

 terially finer anteriorly as in that species ; antennae and legs 

 thinner, the third joint of the former distinctly longer than the 

 fourth ; prothorax nearly as long as wide, less dilated anteriorlv, 

 the sides sometimes very feebly converging toward base, otherwise 

 nearly as in cvqiiicollis ; elytra but little less than twice as long as 

 wide, distinctly wider than the prothorax, with evenly arcuate 

 sides but with the humeri 'only slightl}- exposed at base and but 

 slightly prominent, the apex some ^hat gradually, acutely ogival, 

 the individual angles more minutely prominent and divaricate ; 

 surface with the sculpture similar but finer, the alternate series 

 of carinules scarcely perceptibly more prominent near the base; 

 abdomen coarsely but only moderately closely punctate medially. 

 Length i 2.4-13.0 mm. ; width 3.75-4.1 mm. California (locality
