TENEBRIONID^: 107 



feebly reflexo-explanate and densely, confusedly punctate laterally, 

 strongly, transversely rugose near the edge, which is only moder- 

 ately thick and finely, strongly crenulate; elytra nearly as in 

 (Zgrotiis, more elongate and with the side margins strongly and 

 abruptly though narrowly reflexed; abdomen less opaque, strongly 

 alutaceous, rather finely but strongly, very sparsely punctate 

 throughout; legs nearly as in cegrotus but with the hind tarsi 

 rather more slender though less elongate; last joint of the 

 maxillary palpi but slightly scalene (cf), to smaller though with 

 comparatively little difference in shape (9). Length 18.5-19.5 

 mm.; width 8.5-9.5 rnm. Lower California., .limbatus n. subsp. 

 Elytra with the inner of the two discal costse evident as a rule, though 

 feeble and incomplete, the second costa feeble and not terminating 

 in a prominence; basal angles of the prothorax never obliquely 

 acute but right or very slightly laterally prominent, the base virtu- 

 ally straight from side to side, sometimes with a very feeble sinus 

 opposite the scutellum; elytra constricted just behind the basal 

 margin, the sides of which are acutely prominent laterally, the apex 



rather gradually subacute, not lobiform; legs shorter 2 



2 Elytra much inflated, nearly twice as wide as the prothorax in the 

 female. Blackish-piceous, subopaque, the elytral rugae shining; 

 head transversely, feebly impressed, finely, sparsely punctate, each 

 puncture with a small coarse and very pale subdepressed and con- 

 spicuous hair; prothorax a third or fourth wider than long, three- 

 fifths as wide as the elytra (cf), convex and coarsely, deeply, very 

 confluently punctate throughout, with some smooth areas sublaterally 

 toward apex, broadly explanate laterally, the edge but feebly re- 

 flexed, evidently and rather acutely serrulate, widest and broadly 

 rounded at the sides before the middle, the sides converging thence 

 basally, becoming nearly parallel near the basal angles, which are 

 right, the apical angles not prominent, not at all everted; elytra 

 not quite one-half longer than wide, widest at the middle, with evenly 

 arcuate sides; surface with the costa strong, the space between them 

 across the suture flat, outside of them rapidly sloping, the rugae well 

 separated, the lateral edges very finely explanate; concavities be- 

 tween the rugae with smaller and sparse swollen punctures, not evi- 

 dently pubescent; abdomen finely, sparsely punctate, each puncture 

 with a very minute pale hair. Length (cf, 9) 18.0-18.5 mm.; 



width 9.5-9.7 mm. Arizona, Levette corporalis n. sp. 



Elytra never much inflated, never much more than one-half wider than 



the prothorax and frequently much less 3 



3 First discal costa barely traceable and virtually obsolete. Body 

 larger than in any other of this section, black, opaque; head nearly 

 as in the preceding but with the sparse pale hairs shorter; prothorax 

 similar in sculpture but larger and differing much in outline, three- 

 fifths as wide as the elytra (9 ), more than a fourth wider than long, 

 subparallel, widest before the middle but with the sides subevenly 

 arcuate from apex nearly to the basal angles, the latter minutely 

 subprominent, the edge finely and strongly serrulate; elytra two-
