REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ I37 



scarcely impressed, the anterior canthus broadly rounded, copromi- 

 nent with the posterior ; prothorax two-thirds wider than long, 

 the sides strongly converging from base to apex, subequally and 

 rather strongly arcuate, more so at apex, the latter evenly sinuate 

 and but little more than half as wide as the base, the angles de- 

 flexed, right and rather distinctly rounded ; base broadly bisinuate, 

 the angles but little produced; surface minutely, sparsely punctu- 

 late, becoming strongly but not very coarsely and still sparsely 

 punctate laterally, the bead fine, perfectly straight and unmodified 

 at the basal angles ; scutellum moderate, obtuse ; elytra two-fifths 

 longer than wide, the sides rounding and converging posteriorly 

 to the regularly ogival tip, becoming parallel only toward base, 

 the surface smooth, rather finely rugose posteriorly, strongly and 

 sparsely but not very coarsely punctured, more coarsely and 

 densely behind ; prosternum nearly as in uteana but with the 

 process narrower, less constricted and more acutely rounded at 

 apex ; hind femora with rather small but strong and remote 

 punctures, the abdomen minutely, sparsely and inconspicuously 

 punctulate. Length 9.0 mm.; width 4.5 mm. (cf). Colorado 

 (Salida), — H. F. Wickham inepta n. sp. 



Form more broadly elliptic and more convex, much larger, not quite 

 so shining, black ; head finely, sparsely punctate, the sinus rather 

 deep, subangular, the lobes not very broadly rounded, unimpressed, 

 the anterior canthus similar ; prothorax three-fourths wider than 

 long, the sides as in itiepta^ the apex also nearly similar but three- 

 fifths as wide as the base; base rather strongly bisinuate, the 

 angles moderately and gradually produced ; surface minutely, 

 sparsely punctulate, gradually more strongly but still rather finely 

 and only moderately closely toward the sides, the bead rather fine ; 

 scutellum rather small ; elytra formed nearly as in inepta but with 

 the sides becoming parallel in about basal half ; surface rugose 

 throughout to nearly smooth, always more strongly and deeply 

 rugose on the declivity, the punctures rather small but strong, 

 sparse, larger and close posteriorly; prosternum as in t?iepta, 

 somewhat shining, closely and somewhat asperately punctate, the 

 process similarly rather narrow and elongate, smooth and mod- 

 erately constricted but more broadly and evenly rounded at tip, the 

 abdomen and hind femoi'a finely, sparsely and rather inconspicu- 

 ously punctate. I^ength 10.2-11.5 mm.; width 5.1-5.6 mm. 

 Probably from northern Idaho oblita n. sp. 



Form more elongate, convex, alutaceous, the elytra more shining, deep 

 black ; head finely, sparsely punctured, the sinus rather narrow, 

 moderately deep, parabolic, the lobes broadly rounded, obsoletely 

 impressed, the anterior canthus strongly rounded, a little more 

 prominent than the posterior ; prothorax three-fifths wider than 

 long, the sides sensibly converging and more or less nearly straight 

 to beyond the middle, then more strongly rounded and converging 

 to the apex, the latter moderately sinuate and fully two-thirds as 

 wide as the base, the apical and basal angles nearly as in uteana^
