brous ; head finely but deeply, loosely punctate, the sinus broad, 

 moderately deep and subparabolic, the lobes unimpressed, rather 

 narrowly rounded, the anterior canthus rounded ; prothorax 

 rather long, perceptibly less than one-half wider than long, 

 the apex moderately sinuate and fully two-thirds as wide as 

 the base, the angles right and rather broadly rounded ; sides 

 very moderately, subevenly arcuate throughout, slightly more 

 converging anteriorly but barely becoming parallel even at base ; 

 surface rather sparsely punctate throughout, the punctures ex- 

 cessively minute medially and more visible, though still very fine 

 laterally, the marginal bead rather fine; scutellum moderate; 

 elytra evidently more than twice as long as the prothorax, fully 

 three-fifths longer than wide, parallel and straight at the sides, 

 gradually and obtusely ogival behind; surface nearly smooth, with 

 traces of close-set longitudinal costules, very finely, sparsely punc- 

 tate throughout; prosternum minutely, sparsely punctate, the 

 process but little dilated posteriorly, with its tip rather prolonged 

 and narrowly rounded; abdomen and hind femora minutely, re- 

 motely punctate. Length lo.o mm. ; width 4.12 mm. San 

 Francisco. A single male taken by the writer in the suburbs.

II — Body rather small, elongate, strongly convex, deep black, gla- 

 brous, rather shining, the pronotum at most very feebly aluta- 

 ceous; head finely, but strongly, rather sparsely punctate, the 

 sinus rather broad and shallow, the lobes unimpressed; anterior 

 canthus oblique, not broadly rounded, much less prominent than 

 the posterior ; prothorax visibly less than one-half wider than long, 

 the sides somewhat strongly converging, subevenly and very feebly 

 arcuate from base to apex, the latter feebly and circularly sinuate, 

 two-thirds as wide as the base, the angles right and bluntly 

 rounded ; surface sparsely, extremely minutely j^unctate, still very 

 finely and rather sparsely, though more distinctly, toward the sides, 

 the lateral bead fine; scutellum moderate; elytra a little more 

 than twice as long as the prothorax, more than one-half longer 

 than wide, parallel, gradually ogival at apex; surface nearly 

 smooth, very finely, remotely punctate, the punctures scarcely less 

 remote or more distinct laterally; prosternum sparsely, very 

 minutely punctulate ; hind femora and abdomen remotely punctate, 

 the former somewhat finely but strongly, the latter extremely 

 minutely. Length 10. 6-1 1.2 mm.; width 4.5-4.65 mm. San 

 Francisco. Two male specimens taken by the writer in the 

 suburbs conicicollis n. sp.

posterior ; sides of the prothorax more or less evidently converg- 

 ing from base to apex 13 



Anterior canthus much fuller and broadly rounded, as prominent as
