REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ IO7 



val in posterior two-fifths ; surface very smooth, witli barely a trace 

 of tumescent lines, the punctures minute, moderately close in 

 broad lines as in the preceding species; under surface very mi- 

 nutely, remotely punctulate and polished, the prosternum more 

 opaque and minutely, rugosely punctate, the process rather nar- 

 row, margined strongly almost to the tip. Length 7.5 mm. ; 

 width 3.3 mm. Alameda Co microsticta n. sp. 



20 — Form rather stout for the present group and moderately convex, 

 glabrous, shining and only very faintly alutaceous, deep black, 

 the legs rufo-piceous, the antenuie nearly black ; head finely but 

 not very closely punctate, the sinus moderate, the anterior canthus 

 much less prominent than the posterior ; prothorax formed nearly 

 as in microsticta but much less transverse, barely one-half wider 

 than long, the surface finely but strongly, moderately sparsely 

 punctate, becoming still more strongly and rather closely but un- 

 evenly so laterally, the marginal bead rather fine, strongly curving 

 about the hind angles; scutellum rather small ; elytra barely one- 

 half longer than wide, two and a third times as long as the pro- 

 thorax and equally wide, the sides straight and parallel, gradually 

 rounding and converging behind the middle, the apex narrowly 

 parabolic; surface with fine but unusually strong, moderately 

 close-set punctures, with the less punctate lines narrower and dis- 

 tinctly tumescent ; under surface minutely, sparsely punctate 

 throughout, the prosternal process rather wide, very faintly mar- 

 gined at the sides along the coxje, its apex unusually deflexed and 

 convex. Length 9.2 mm. ; width 3. S2 mm. California. 



picipes n. sp. 



21 — Lateral bead of the prothorax very fine, rounding the hind angles 

 and extending inward along the base for only a short distance. 

 Body rather strongly convex, subcylindric, glabrous, deep black, 

 the legs dark rufous, the antennae nearly black ; surface rather 

 shining though somewhat alutaceous; head rather small, finely, 

 strongly, somewhat closely punctate anteriorly, more finely and 

 sparsely behind the suture, the sinus moderately broad, the anterior 

 canthus moderately full, less prominent than the posterior; pro- 

 thorax as in picipes but rather more rapidly narrowed anteriorly, 

 the angles obtuse but rather less rounded ; surface very minutely, 

 rather sparsely punctate, still very finely and rather sparsely so 

 laterally ; scutellum small ; elytra nearly as in picipes but nar- 

 rower, the surface similar but with the punctures still smaller and 

 feebler; prosternal process narrower, finely though very evidently 

 margined along the coxae, similarly much defiexed and convex at 

 its apex. Length 7.7 mm. ; width 3.35 mm. San Francisco. 

 A single specimen taken by the writer in the suburbs. 



inflexula n. sp. 



Lateral bead even finer, extending along the basal margin almost to the 

 middle. Body rather more elongate, convex, feebly alutaceous; 

 coloration as in injlexiila^ the upper surface bearing short but
