TENEBRIONID.E 97 



breviated, black, rather shining, the anterior parts dull; head 

 feebly impressed, the punctures fine and not dense, becoming 

 coarser and close basally; prothorax short, a little less than twice 

 as wide as long in both sexes, the apex moderately sinuate, evi- 

 dently narrower than the base, with blunt angles, the sides broadly 

 rounded, converging and becoming feebly sinuate toward the basal 

 angles, which are right and not rounded, the base broadly arcuate, 

 becoming sinuate laterally; surface coarsely, very deeply and con- 

 fluently punctate, convex, becoming explanate though scarcely 

 at all reflexed and transversely rugose laterally; elytra about 

 three times as long as the prothorax, and, in the female, not quite 

 twice as wide, but little longer than wide in the latter sex, having 

 the usual costse well developed, the rugose intervals with the fine 

 micro-setiferous granules numerous and conspicuous; abdomen not 

 very coarsely but strongly, closely and subasperately punctate 

 (cf) or more finely and sparsely though strongly so ( 9 ), the small 

 hairs blackish. Length 16.5-18.0 mm.; width 9.0-11.0 mm. 



Colorado, F. G. Schaupp porcatula n. subsp. 



Elytral pubescence as in the preceding, color almost perfectly black, 

 the hind body much inflated, dull, the elytra feebly shining; head with 

 the punctures less evidently closer though slightly coarser basally than 

 in porcatula; prothorax smaller than in any other species, not quite 

 twice as wide as long, the evenly sinuate apex much more notably 

 narrower than the base, with the angles right and scarcely blunt, 

 the sides broadly rounded rather behind the middle, strongly con- 

 verging and almost straight thence to the apex, feebly so but dis- 

 tinctly sinuate to the basal angles, which are more prominent, sub- 

 acute but blunt, the base truncate medially, obliquely sinuate thence 

 to the angles; surface nearly as in porcatula but with a feeble im- 

 pression along the basal truncature, and, at each sinus, a rather 

 large area devoid of punctures; elytra (9) nearly as in porcatula 

 but more evidently longer than wide and rather more than twice as 

 wide as the prothorax, similarly evenly oval and widest at the middle 

 but differing in the relatively stronger outer and feeble inner of the 

 discal ridges, the sutural region more depressed, the intervals much 

 less sharply undulato-rugose, with the fine granules almost similarly 

 close-set and distinct; abdomen (9) more strongly and closely 

 punctate than in porcatula, with similar small fuscous hairs. 

 Length 18.0 mm.; width 10.7 mm. Arizona (locality not stated), 



H. F. Wickham parvicollis n. sp. 



Elytral pubescence half as long as the length of the eye, very coarse, 

 pale yellowish and conspicuous; color grayish-black; general form 

 nearly as in sordida but more depressed; head feebly, indefinitely 

 impressed, strongly but not densely punctate, the small pale hairs 

 distinct; prothorax two-thirds to three-fourths wider than long, 

 parallel and broadly arcuate at the sides, moderately sinuate at 

 apex, the angles blunt; basal angles unusually feebly produced, 

 acute; surface moderately convex, coarsely, not very densely and 

 irregularly punctate, moderately broadly concavo-explanate at
