obsolete; disk rather strongly convex, feebly, narrowly and uneveulj' im- 

 pressed along each side near the edge; surface unevenly and coarsely but not 

 very strongly rugulose, very coarsely, unevenly, rather feebly and very sparsely 

 punctate. Elytra at base scarcely wider than the pronotiim; sides rather 

 strongly divergent and straight; together broadly, evenly and feebly incurvate 

 at apex; oiiter angles strongly and evenly rounded; disk transversely and 

 distinctly convex, slightly shorter than the apical width, nearly one-half 

 longer than the prothorax, coarsely, very strongly and unevenly inigulose;. 

 rugulosities polished, large, arranged in a generally longitudinal direction, 

 divided by the very irregular coarse and ill-defined punctures. Abdomen 

 having six exposed segments; together much longer and slightly wider than, 

 the elytra; exterior sides of the border arcuate, inner sides straight and paral- 

 lel; border wide, feebly inclined; surface strongly convex, finely rather 

 densely and asperately punctate; surface sub-alutaceous, feebly shining. 

 Legs short and robust; middle and posterior tibire very coarsely and rather 

 densely spinulose exteriorly; last joint of the posterior tarsi much longer 

 than the first four together. L-^'ngth, 2.9 mm. 



California (Alameda Co., 1). Mr. Harford. 



The humeri have no traces of callosity, and the median 

 portions of the pronotum are evenly convex without traces

 differs apparently in its greater slenderness.

P. longipalpns n- sp. — Broad, depressed, slightly wider behind; body 

 black throughout; antennae same; palpi intense black throughout; legs 

 piceous-black, tarsi very dark reddish-fuscous; pubescence very fine, rather 

 long, sub-recumbent, moderately dense, dark grayish in color; integuments 

 polished. Head moderate or small, strongly constricted immediately behind 

 the eyes, about as wide as long; eyes large, very prominent; front feebly 

 convex, finely, evenly and rather densely punctate; having on a line slightly 

 in advance of the middle of the eyes, two round impressed fovete whiih are 

 mutually slightly less than twice as distant as either from the eye; vertex 

 transversely impressed between the antennae; the latter long, very slender 

 and filiform, nearly as long as the elytra and abdomen together, clothed 

 densely with very minute pubescence; joints one, three to seven, and eleven 

 nearly equal in length, the first slightly more robust and the last most slen- 

 der, fusiform; joints eight to ten very slightly shorter and rather more slen- 

 der than the seventh, second much the shortest, one-half as long as the third 

 and more than twice as long as wide. Prothorax widest in the middle where 

 the sides are very obtusely and feebly angulate, and where it is about two-
