REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 95 



rather closely punctate medially, more strongly and very closely 

 laterally, the marginal bead fine; scutellum rather small; elytra 

 about two-fifths longer than wide, more obtusely ogival at tip than 

 in the two following forms, smooth or with a few very feeble and 

 irregular impressed lines, the punctures minute and sparse sutur- 

 ally, stronger, closer and very distinct laterally ; prosternum finely, 

 sparsely punctate, the process wide, convex, broadly arcuato- 

 truncate at tip; abdomen extremely minutely and obsoletely but 

 rather closely punctulate, the hind femora rather distinctly though 

 not closely punctate. Length 9.8 mm. ; width 4.7 mm. Cali- 

 fornia (Amedee, Lassen Co.), H. F. Wickham. Described from 

 a single male specimen lassenica n. sp. 



Form more narrowly oblong-elongate, rather more convex. Body 

 black, dull and strongly alutaceous in lustre ; head finely but 

 strongly, not very closely punctate, deeply and rather narrowly 

 sinuate at apex, the lobes flattened, the canthi subequally promi- 

 nent, the anterior rather narrowly rounded ; prothorax less trans- 

 verse, three-fifths wider than long, the sides more broadly and 

 evenly rounded, more gradually converging anteriorly and be- 

 coming parallel and straight only behind the middle, otherwise 

 nearly as in lassenica, the basal sinuations very feeble and the 

 inner side of the hind angles scarcely oblique; elytra parallel, as 

 wide as the prothorax, one-half longer than wide, more gradually 

 and acutely ogival at apex, smooth, with some feeble and uneven 

 scratches, very minutely and sparsely punctate suturally, very 

 distinctly and much more closely near the sides, the margin very 

 finely reflexed ; prosternum finely but strongly, rather closely 

 punctured and micro-setigerous, the abdomen shining, very mi- 

 nutely, rather sparsely and obsoletely punctulate, the hind femora 

 unusually finely, obsoletely and remotely punctulate. Length 9.8 

 mm. ; width 4.5 mm. Nevada (Reno). A single specimen of 

 undetermined sex taken by the writer on the banks of the Truckee 

 River nevadensis n. sp. 



A Body very nearly as in nevadensis but with the prothorax very 

 slightly less transverse and with the basal sinuations stronger, 

 so that the hind angles project posteriorly for a very short 

 distance, with their inner sides oblique ; sculpture similar, the 

 elytra slightly smoother, with the fine punctures near the sides 

 relatively rather less distinct ; hind femora notably more strongly 

 and less sparsely punctate and a little more pubescent. Length 

 9.5 mm.; width 4.5 mm. Nevada (Carson City), H. F. 

 Wickham carsonica n. subsp. 



13 Body oblong, parallel, moderately convex, deep black, alutaceous 

 in lustre, the elytra more strongly ; minute setae of the punctures not 

 projecting beyond the limits of the latter; head somewhat coarsely 

 but not very closely punctate, unimpressed at the lobes, the apical 

 sinus rather deep and abruptly formed ; anterior canthus rounded, 

 slightly more prominent than the posterior; antennaB rather
