CASEY 



straight and parallel to apical two-fifths, then gradually arcuate 

 and converging to the rather acutely ogival tip ; surface nearly as 

 in montana, the strong and moderately large punctures less sparse, 

 becoming somewhat close-set and coarse laterally ; prosternum 

 rather coarsely but sparsely punctate, the process dilated and 

 rounded behind the coxae, the marginal bead rather feeble but en- 

 tire ; abdomen rather finely but very distinctly, sparsely punctate ; 

 hind femora strongly, conspicuously, evenly but not very closely 

 punctate throughout. Length 12.2 mm. ; width 5. 2 mm. Cali- 

 fornia. Cab. Levette canonica n. sp. 



Form much broader, more oblong-oval, only moderately convex, deep 

 black, the tarsi and antennae picescent, the upper surface dull and 

 strongly alutaceous, the hairs rather long, moderately sparse, ful- 

 vous and distinct ; head strongly, rather sparsely, not very coarsely 

 punctate, the sinus narrow, deeply angular; anterior canthus 

 full and broadly rounded, as prominent as the posterior ; prothorax 

 as in montana but more narrowed anteriorly, the apex more 

 deeply sinuate and only three-fifths as wide as the base, the base 

 rather more strongly and more broadly sinuate laterally, the punc- 

 tures and lateral bead nearly as in canonica; scutellum as in the 

 latter ; elytra shorter, less than one-half longer than wide, the 

 sides parallel and straight to apical two-fifths, then moderately 

 rapidly converging and arcuate to the subparabolic apex ; surface 

 smooth, feebly undulato-rugose posteriorly, rather finely but dis- 

 tinctly, sparsely punctate, more coarsely though still not very 

 deeply and but little less sparsely laterally ; prosternum strongly, 

 moderately closely punctate, the process feebly dilated and rounded 

 behind the coxae, convex, the beaded margin obsolescent at apex ; 

 hind femora strongly and rather closely punctured toward base 

 but sparsely and less coarsely so thence distally; abdomen finely, 

 feebly and sparsely punctulate. Length 11.7 mm.; width 5.8 

 mm. California (South Fork of the Kaweah River) .

7 Body oblong-suboval, moderately convex, dull and alutaceous, 

 rather grayish-black, the legs, antennae, mouth-parts and clypeus 

 rufescent; pubescence coarse, moderately long, fulvous and dis- 

 tinct though rather sparse ; head somewhat coarsely and closely 

 perforato-punctate, the sinus moderately narrow and parabolic, 

 the anterior canthus narrowly rounded, about as prominent as the 

 posterior ; prothorax one-half wider than long, the sides broadly 

 rounded, strongly converging apically, becoming nearly parallel 

 toward base, the apex deeply sinuate, barely three-fifths as wide 

 as the base, the angles right and scarcely even blunt, very dis- 

 tinct ; surface rather sparsely but strongly punctate, coarsely and 

 less sparsely so laterally, the marginal bead fine, arcuate near the 

 base ; scutellum moderate, picescent ; elytra about two and a third 

 times as long as the prothorax, rather obtusely ogival with strongly 

 arcuate sides in apical two-fifths, parallel thence to the base ; sur- 

 face nearly smooth, undulato-rugose apically, strongly, somewhat
