122 MEMOIRS ON THE COLEOPTERA 



as wide as the prothorax, the impressions moderate, arcuate; 

 antennae piceous, paler apically; prothorax apparently distinctly 

 longer than wide, the sides broadly and very moderately arcuate, 

 gradually converging and very broadly, feebly sinuate behind to 

 the perfectly right and very sharply denned angles; base broadly, 

 very feebly sinuate medially, scarcely at all margined even at the 

 extreme sides, three-fourths the maximum width; surface moderately 

 convex and reflexed at the sides, the inner depression broadly, 

 feebly impressed, not at all sharply denned, the outer wanting though 

 with a minute and feeble ridge extending obliquely inward from 

 each angle; median stria strong; elytra three-fourths longer than 

 wide, oblong, with broadly and feebly arcuate sides and strongly 

 rounded apex, only a little less than one-half wider than the prothorax, 

 the striae fine but abruptly deep, not punctate, the intervals almost 

 perfectly flat even at the sides; scutellar stria short, fine, oblique; 

 last ventral (cf) with a fine transverse crease* near the tip, having 

 a single anal seta at each side. Length (cf) 13.5 mm.; width 4.8 mm. 

 California. A single example without more definite indication of 

 locality, from the Levette collection annosus n. sp. 



Elytral margin narrowly reflexed, the surface rapidly declivous toward 

 the humeri as usual, the striae more impressed, the intervals always 

 at least feebly convex laterad 12 



12 Elytra subcylindric, very convex, the body conspicuously narrow and 

 elongate. Color deep black, the legs black, the tarsi rufo-piceous; 

 surface strongly shining, the elytra only faintly alutaceous even in 

 the female; head moderate though nearly three-fourths as wide as 

 the prothorax, the impressions short and deep; prothorax nearly 

 as in castanipes though very much narrower, apparently a little 

 longer than wide, the sides broadly rounded to about basal seventh or 

 eighth, there rather abruptly becoming almost parallel to the angles, 

 which are but little more than right, due to a basal arcuation, and 

 sharply defined ; base transversely subarcuate, sometimes with a small 

 feeble median sinuation, not quite three-fourths the maximum width; 

 surface convex, finely margined, the inner depression very short, 

 broadly impressed, only about a fifth the total length, the outer 

 wholly obsolete; median stria strong, subentire; elytra almost four- 

 fifths longer than wide, very steeply and deeply convexo-declivous 

 at the sides, becoming nearly vertical toward the extremely and unusu- 

 ally narrowly reflexed margins, parallel, the sides only very feebly 

 arcuate, about a third wider than the prothorax, the apex strongly, 

 rather narrowly rounded; striae fine but very deep, smooth and 

 punctureless, the intervals nearly flat, becoming feeblylconvex laterad ; 

 humeral denticle small though rather distinct; legs moderately short 

 and slender. Length ( 9 ) 12.0-13.0 mm.; width 4.1-4.65 mm. Cali- 

 fornia (Mendocino Co. Hermitage and Guallala).. . esuriens n. sp. 



Elytra elongate-oval, less convex and less deeply or vertically declivous 

 at the sides; body not so narrow or subcylindric, the prothorax 



*A fine impressed transverse and subarcuate line, apparently dividing the last 

 abdominal segment in Pterostichus, is frequently evident but I am unable to deter- 

 mine its origin or significance.
