REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 143 



otherwise nearly as in hystrix, but with the coarse punctures near 

 the sides not elongate and with the narrow interspaces less smooth, 

 and also differing in having the sloping flanks somewhat sub- 

 explanate basally and the marginal bead coarser ; scutellum similar 

 though a little larger ; elytra much more elongate, fully one-half 

 longer than wide, nearly three times as long as the median line of 

 the prothorax, less declivous posteriorly, rounded in apical third, 

 the apex feebly produced, the sides parallel and straight (c?) or 

 feebly arcuate and somewhat inflated posteriorly ( ? ) ; surface 

 very smooth, the punctures smaller, only moderately coarse but 

 perforate and much more widely separated ; prosternum similarly 

 strongly, closely punctate, the process larger, more constricted, 

 the lateral beading much finer ; abdomen with rather small but 

 strong, moderately sparse punctures. Length 7.88.2 mm. ; 

 width 3.8-4.6 mm. Nevada (near Reno), H. F. Wickham. 



longipennis n. sp. 



4 Form stout, convex, deep black, somewhat alutaceous in lustre ; 

 head punctured nearly as in hystrix, the sinus rather small, 

 moderately deep, broadly angular, the lobes broadly rounded; 

 sides obtusely prominent before the eyes ; prothorax four-fifths 

 wider than long, the sides very moderately rounded and not very 

 strongly converging anteriorly, becoming parallel and straighter 

 posteriorly, the strongly sinuate apex three-fourths as wide as the 

 base, the angles and base as in the preceding species ; surface not 

 coarsely but strongly, sparsely punctured, the punctures becoming 

 coarse, dense and slightly elongated laterally, the bead fine, the 

 hind angles more narrowly produced and more acute than in the 

 preceding ; scutellum very small ; elytra feebly inflated posteriorly 

 (cT) or strongly so (9), the sides broadly arcuate at or behind 

 the middle, distinctly wider than the prothorax, the apex obtusely 

 ogival and somewhat prolonged ; surface coarsely and deep ly but 

 rather sparsely punctate, much more finely so on the opaque pos- 

 terior declivity ; prosternum coarsely, rather closely punctate, the 

 process longitudinally and strongly convex ; abdomen sparsely but 

 strongly punctate, polished. Length 6.6-7.0 mm. ; width 3.25 

 3.75 mm. Nevada (Reno). A small series taken by the writer 

 on the banks of the Truckee, in the suburbs of the town. 



inflatus Csy. 



Form still stouter, less convex, oblong, black, moderately shining, larger 

 in size ; head finely but strongly, subevenly and closely punctate, 

 the sinus moderate, deep, subangular, the lobes broadly rounded ; 

 prothorax twice as wide as its median length, inflated, much wider 

 just behind the middle than at base, the sides strongly, subevenly 

 rounded, more converging anteriorly, the apex strongly sinuate, 

 fully two-thirds as wide as the base, the angles right, rather nar- 

 rowly rounded, the basal rather narrowly but abruptly and moder- 

 ately produced and acute ; surface finely and sparsely punctate, 

 becoming coarsely and densely so, with the punctures just visibly 

 elongate, laterally, the bead rather fine ; scutellum very small, as
