and rounded apical angles, the sides generally with a distinct sub- 

 angulation at the middle ; apical sinus broad and shallow, two- 

 thirds as wide as the base ; surface more minutely and less closely 

 punctate than in the preceding, the punctures however unusually 

 close-set, the fine margin not curved at base so completely about 

 the basal angles; scutellum nearly similar but less obtuse ; elytra 

 nearly similar but a little shorter and especially more gradually 

 and acutely ogival posteriorly, the even finer punctures similarly 

 disposed, the subimpunctate lines often irregularly costuliform ; 

 under surface and femora minutely, rather sparsely punctate. 

 Length 8.29.2 mm.; width 3.2-3.85 mm. San Francisco.

Form still shorter, subcylindric, strongly convex, much more obtuse 

 before and behind, deep black, the legs rufo-piceous ; upper sur- 

 face alutaceous ; head finely but not very closely punctate, the 

 sinus shallow, the oblique side margins sinuous at the ends of the 

 oblique sutures an unusual character in this genus, the frontal 

 parts rufescent as in the two preceding ; prothorax rather elongate, 

 evidently less than one-half wider than long, the sides very feebly 

 converging and almost straight from the base nearly to apical third, 

 then rounded and strongly converging but not angulate, the apex 

 broadly and shallowly sinuate, nearly four-fifths as wide as the base, 

 the angles broadly rounded ; surface finely but strongly, not very 

 closely and unevenly punctate, becoming a little more strongly 

 and closely so laterally, the marginal bead fine, arcuate at base ; 

 scutellum rather small ; elytra short, barely one-half longer than 

 wide and but little more than twice as long as the prothorax, par- 

 allel, very obtusely ogival at tip ; surface with fine but rather 

 strong, moderately close-set punctures disposed as in the preced- 

 ing, the subimpunctate lines tumescent; under surface finely punc- 

 tate, the prosternum rather strongly and somewhat closely. 

 Length 7.9 mm. ; width 3.5 mm. California. Cab. Levette.

19 Body moderately elongate, parallel, convex, deep black, the legs 

 in great part and the antennae apically rufescent ; upper surface 

 smooth and dull, strongly alutaceous; head rather small, very 

 finely, not densely punctate, the sinus rather deep and narrower, 

 the oblique sides straight ; anterior canthus about as prominent as 

 the posterior; prothorax short, three-fifths wider than long, the 

 sides subevenly rounded, rather strongly converging anteriorly, 

 becoming parallel in about basal half, the apex barely more than 

 three-fifths as wide as the base, with moderately deep sinus and 

 broadly rounded angles ; base almost truncate, with obtuse angles ; 

 surface minutely, rather sparsely punctulate, more strongly but 

 still not very closely so laterally, the marginal bead extremely fine, 

 only slightly arcuate at base; scutellum moderate, polished; ely- 

 tra not quite one-half longer than wide, two and one-half times as 

 long as the prothorax, parallel, gradually moderately acute and ogi-
