Goleopterological Notices, VII. 339 



Prothorax not lono;er than Avide, the sides distinctly sinuate near the base; 

 elytra red-brown with polished metallic green or cupreous side margins. 



angiisticollis Fisch. 



Prothorax elongate, the sides feebly oblique toward base and less distinctly 



sinuate; elytra deep black, generally with more obscure metallic margins. 



velutinus Menet. 



Basal joint of the anterior male tarsi densely pubescent beneath only in apical 



half; prothorax widest and broadly angulate at the sides barely before the 



middle; sides of the elytra not reflexed and obscurely sculptured, having 



merely a minute elevated edge longipes n. sp. 



In the first two species the reflexed side mai'gins of the pro- 

 thorax are also occasionally feebly metallic greenish in lustre. 



P. longipes. — Elongate, moderately ventricose; body above deep and 

 opaque black throughout, the legs and under surface shining and with an ex- 

 tremely faint violaceous lustre. Head very elongate, the vertex smooth; gense 

 thick, but little dilated, with a small angular notch beneath the eyes; neck 

 long, without trace of constriction ; supra-orbital ridges fine behind, moderate 

 and subangulate above the antennse ; eyes relatively rather small in size ; an- 

 tennae very long, nearly % as long as the body, slender, feebly thickened 

 toward base, the first joint thicker, elongate, feebly sigmoid, 2.7 mm. in 

 length, much shorter than the next two; third joint 2 mm. in length. Pro- 

 thorax distinctly longer than wide, moderately dilated anteriorly, the sides 

 feebly convergent and broadly, feebly arcuate from just before the middle to 

 the apex, more strongly oblique and nearly straight posteriorly to basal sixth, 

 there sinuate and thence parallel and straight to the base; angles right and 

 slightly blunt; base % the maximum width and scarcely as wide as the head; 

 disk almost flat, the impressions all extremely feeble; reflexed side margins 

 nearly as in velutinus. Elytra, viewed perpendicularly, % longer than wide, 

 3 times as long as the prothorax and 2% times as wide, widest near apical 

 third, the sides thence feebly and evenly arcuate to the base, the humeri 

 wholly undistinguishable, disk in profile vertical behind and slightly pro- 

 duced at tip, very feeblj^ convex anteriorly, not striate but with minute sub- 

 obsolete punctures arranged serially, with three intervals on each a little more 

 pronounced as usual; margin nearly flat, more coarsely but unevenly punctate, 

 the punctures broadly impressed and with a single series of minute, widely 

 separated but strongly elevated granules; minute subvertical edge finer than 

 that of the prothorax. Length 20.0 mm.; width 8.8 mm; length of head to 

 extremity of mandibles 5.7 mm. ; length of hind tibia 9.5 mm. 



California (Humboldt Co.). 



I obtained a single male of this species near the coast ; it was 

 at the time walking with rather slow straddling gait on the sur- 

 face of a decayed log. The sides of the elytra are very oblique 

 before posterior third, and there is scarcely a trace of the broadly 

 rounded humeri of angusticoUis and velutinus.
