protliorax. As the figure corresponds exactly with the examples 

 which are referred above to ventricosus, and, as supplementary 

 series of punctures are quite as evident here as in striatopunc- 

 iatus, I thinlv tliat the synonymy now proposed may be some- 

 what more appropriate, although it is of course impossible to be 

 absolutel}^ sure in the absence of types. 



16. H. gentilis n. sp. — Moderately ventricose, shining, the pronotum 

 slightly alutaceous, deep black throughout. Head elongate, moderate in 

 width, the vertex feebly and transversely wrinkled anteriorly, the gense not 

 greatly developed and having a small angulate notch ; supra-orbital ridges 

 fine, strongly elevated at the antennte and there separated from the median 

 parts of the front by a deep depression ; antennae fully % as long as the body, 

 slender, only slightly thicker toward base, the first joint slightly stouter, 

 nauch shorter than the next two. Prothorax relatii-ely rather small, as wide 

 as long, moderately dilated and broadly rounded anteriorly, the sides sinuate 

 behind, becoming straight and parallel in about basal sixth ; base 3^^ the maxi- 

 mum width or a little more, about as wide as the head ; angles right : disk 

 only feebly convex, the impressions superficial, the median line fine but dis- 

 tinct ; reflexed sides moderately deep and strong. Elytra almost evenly ellipti- 

 cal, almost evenly and moderately convex, % longer than wide, more than 3 

 times as long as the prothorax and barely 2^2 times as wide, not very full a1> 

 the humeri ; rather finely but deeply and very evenly striate, the striae finely 

 punctured, much more coarsely so sublaterally ; intervals convex, confused 

 only in a very narrow area along the sides and distinctly traceable throughout. 

 Length 14.0-18.0 mm. ; width 6.5-8.8 mm. 



California (near Montei'ey). 



'^he ample series of ten specimens before me, represents a species 

 allied somewhat to striatus but diflfering in its broader and much 

 shorter prothorax, with more strongly reflexed side margins^ 

 The intercoxal plate of the mesosternum is generally flat, with, 

 fine raised side margins which are interrupted at the middle and 

 with the usual deep posterior sinus. The female is but little 

 more ventricose than the above described male and has the pro- 

 thorax relatively a little smaller, but scarcely diff"ers otherwise. 

 The pubescent pad of the first anterior tarsal joint of the male 

 extends through a little more than apical half. 



The emargination of the gense is a very variable character, and, 

 in some specimens, the nick when small may be evident on one 

 side of the head and obliterated on the other. 



17. B. strictus n. sp. — Moderately ventricose, the head and pronotumi 

 strongly alutaceous, the elytra somewhat shining, deep black throughout. 

 Head quite stout and only moderately elongate, almost smooth, the gense witb
