120 CASEY 



punctate and with short pubescence, the process wide, subpar- 

 allel ; hind femora rather strongly but sparsely, the abdomen 

 minutely and remotely, punctate. Length 14.2 mm. ; width 6.4 

 mm. ($). San Francisco Co., Chas. Fuchs.... expansa n. sp. 



Form much narrower and relatively more convex, polished throughout 

 and very much more shining, deep black ; head rather finely but 

 strongly, moderately closely punctate, the anterior canthus rather 

 narrowly rounded though not at all pointed; prothorax much less 

 transverse, but little more than one-half wider than long, the apex 

 moderately deeply sinuate, nearly two-thirds as wide as the base, 

 the angles obtuse but rather narrowly rounded, the base broadly 

 arcuate medially, just visibly and transversely sinuate laterally ; 

 surface finely, rather distinctly but sparsely punctate, rather 

 strongly though not coarsely, sparsely so laterally, the bead moder- 

 ately thick ; elytra of peculiar form, fully one-half longer than 

 wide, the sides gradually evenly arcuate and converging posteriorly 

 to the acutely ogival apex, becoming parallel only toward base, 

 very coarsely but rather sparsely punctured, densely so apically, 

 the surface rugose ; prosternum polished, very minutely, remotely 

 and inconspicuously punctate, the process more constricted inter- 

 coxally than in expansa and with the apical angles more rounded ; 

 hind femora and abdomen very finely, sparsely punctate. Length 

 12.7 mm. ; width 5.7 mm. San Francisco. A single specimen 

 taken by the author in the suburbs franciscana n. sp. 



8 Body very broadly oblong, rather strongly convex, deep black, 

 polished, the anterior parts somewhat alutaceous ; head with rather 

 small but strong, moderately close punctures, the anterior canthus 

 rather narrowly rounded; prothorax short, fully three-fourths 

 wider than long, the sides more evenly rounded anteriorly than in 

 expansa, the apex similar but with less thickened bead laterally, 

 three-fifths as wide as the base, the latter similarly truncate but 

 less prolonged backward laterally, being very feebly, transversely 

 sinuate toward the sides; surface finely, sparsely punctate, be- 

 coming strongly and somewhat coarsely though still sparsely so 

 laterally, the marginal bead rather fine ; scutellum smaller, much 

 less transversely triangular; elytra nearly as in expansa but with 

 the sides becoming arcuately convergent behind at about basal 

 third and with the apex more acutely ogival, the punctures simi- 

 larly very coarse and the surface rugose ; prosternum very minutely, 

 sparsely and inconspicuously punctate, the process but feebly 

 constricted intercoxally ; hind femora and abdomen very finely, 

 remotely punctate. Length 12.4 mm.; width 5.8mm. Near 

 San Francisco, G. W. Dunn truncata n. sp. 



Body much narrower and more elongate, parallel, similarly convex, 

 deep black, strongly shining, the anterior parts slightly alutaceous ; 

 head similarly though much more sparsely punctate, the anterior 

 canthus more rounded and less oblique ; antenna? not very slender, 

 the outer joints not much enlarged ; prothorax not more than one-
