TENEBRIONID/E 157 



A Form nearly as in hiliubilis but less shining and with the elytra 

 picescent; head nearly similar, the eyes more convex; antennae 

 similar; prothorax not three-fifths as wide as the elytra, almost as 

 in the preceding, widest before the middle but with the base rather 

 narrower than the apex and with the side margin even less defined, 

 obsolescent; elytra nearly three-fourths longer than wide, widest 

 at three-fifths, almost as in inhabilis but duller and less convex 

 and with a fine, feebly eroded line, on each, parallel to and at some 

 distance from the suture, the subacute side margin wholly obsolete 

 even basally, the humeral carinule distinct but short, the punctures 

 notably larger, closer, deeper and unequal in size; abdomen rather 

 shining, minutely punctulate; legs shorter, very slender. Length 



(9 ) 20. 8 mm.; width 10.3 mm. Kansas retusus n. subsp. 



Elytra with more or less evident longitudinal obtuse lines 3 



3 Form elongate-oval, very convex, deep black and highly polished, 

 the anterior parts and abdomen alutaceous; head nearly as in the 

 preceding, deeply and acutely impressed transversely; antenna? 

 scarcely as long as the prothorax, the latter (a 71 ) nearly one-half 

 wider than long and fully two-thirds as wide as the elytra, as in 

 inhabilis throughout, except that the sparse punctulation is still 

 more excessively minute, the surface at the sides more shining, the 

 basal margin not at all sinuate near the basal angles, which are very 

 obtuse and blunt as well, not distinct, and that the greatest width 

 is very slightly before the middle and not exactly at the middle as 

 in that species, the sides similarly broadly, subevenly arcuate; the 

 apex, also, is rather more sinuate though very feebly; elytra fully 

 four-fifths longer than wide, evenly oval, widest but little behind the 

 middle, the apical lobe large though feebly defined, the sides evenly 

 arcuate, with the margin rather acutely defined to apical fourth, the 

 ridge at the humeri short but strongly elevated and cariniform; 

 surface very convex, the punctures rather strong, only moderately 

 small and not very sparse, each with three wide irregular impressed 

 lines, the median much the broadest, the wide swollen intervals 

 broadly convex; legs long and very slender. Length (d 71 ) 20.0 mm.; 

 width 8.8 mm. New Mexico (locality unrecorded). 



fastigiosus n. sp. 



Form rather narrow, not quite so convex, similarly deep black and lus- 

 trous; head not so sharply impressed, otherwise nearly similar; 

 prothorax nearly similar throughout, less than two-thirds as wide 

 as the elytra, the latter not more than two-thirds longer than wide, 

 moderately convex above, as usual rapidly convex and becoming 

 vertical at the sides, widest at three-fifths, the apical lobe large, 

 short and feebly defined, the sides strongly arcuate, less arcuate and 

 converging from behind the middle to the base, the side margins 

 very narrowly rounded in section but without trace of acuteness at 

 any part, the basal carinule extremely short and confined to the 

 humeral angle itself; surface of each with two rather fine but broadly 

 and feebly elevated vestigial ridges, wholly unlike the broad obtuse 

 ridges of fastigiosus, polished and smooth, the punctures small but
