remotely punctate throughout, more strongly near the sides, the 

 punctures impressed as in the two preceding; prosternum very 

 minutely, sparsely punctate, the process broadly rounded, margined 

 nearly to the apex ; hind femora finely but strongly, moderately 

 sparsely punctate, the abdomen minutely, very remotely so. 

 Length 14.3 mm. ; width 5.S mm. Berkeley, Alameda Co. 



protensa n. sp. 

 14 — Body rather stout for the present group, strongly convex, black 

 throughout, alutaceous, the elytra less so, glabrous; head rather 

 finely and sparsely but strongly punctate, the sinus very broad 

 and somewhat parabolic, the broadly obtuse lobes unimpressed; 

 prothorax rather large, fully one-half wider than long, the sides 

 parallel and nearly straight in about basal half, gradually rounded 

 and strongly converging thence to the angles, which are right 

 and slightly blunt ; apical sinus moderately deep, three-fifths as 

 wide as the base, the latter posteriorly obliquely sinuous laterally ; 

 surface sparsely, very minutely punctate, becoming more closely 

 and much more strongly, though not coarsely so, laterally, the 

 bead rather strong, the fine but strong groove flexed along the 

 apex to lateral fourth; scutellum broadly and obtusely angulate ; 

 elytra two and a third times as long as the prothorax, ratlier 

 more than one-half longer than wide, parallel, unusually obliquely 

 and gradually narrowed to the narrowly obtuse tip ; surface some- 

 what uneven and irregularly crumpled, the punctures sparse but 

 rather large for this group, impressed as in the preceding; pro- 

 sternum finely but strongly, sparsely punctate, the process obtuse, 

 with a strong lateral margin not extending behind the coxae ; hind 

 femora rather coarsely, deeply and not very sparsely punctate, 

 the abdomen minutely, remotely so, more strongly and closely 

 on the basal segment. Length 14. 8 mm. ; width 6.3 mm. 

 Cal if ornia thoracica n . sp . 



Body less stout, elongate, parallel, rather convex, deep black, gla- 

 brous, somewhat strongly shining, scarcely alutaceous anteriorly; 

 head rather finely but strongly, unusually densely punctate, the 

 sinus not very broad, rather deeply parabolic, the lobes broadly 

 obtuse, unimpressed; prothorax fully one-half wider than long, 

 a little wider behind the middle than at base, the sides parallel 

 and broadly arcuate, somewhat sinuate toward base, moderately 

 rounding and converging before the middle, the apex with shallow 

 circular sinus, three-fourths as wide as the base, the angles some- 

 what obtuse but not broadly rounded ; surface finely and rather 

 sparsely but distinctly punctate, not very closely though much 

 more strongly and relatively coarsely so laterally, the marginal 

 groove along the beading flexed inward at apex; scutellum not 

 very transverse, sharply triangular; elytra parallel, fully two- 

 thirds longer than wide, the sides more arcuately and less 

 obliquelv converging at apex; surface slightly uneven, undulate 

 and with traces of three longitudinal ribs on each apicall_y, the 

 punctures less sparse than usual and much larger though not
