TENEBRIONID.E i6i 



B In general outline rather similar to the preceding forms but with 

 the elytra piceous-brown and subopaque, black, anterior parts 

 and more or less piceous under surface feebly alutaceous in lustre; 

 head broadly and feebly impressed transversely, sparsely and not 

 at all coarsely punctate throughout; antennae long (cf) or 

 much shorter ( 9 ) ; prothorax as in obovatus throughout, the sin- 

 uation of the converging sides anteriorly still more perceptible, 

 the sinus at each side of the base much broader and feebler; 

 elytra similar in form but more dilated and much duller, confusedly 

 creased and having each also two or three fine impressed longitu- 

 dinal lines formed of connected subsinuous creases, smooth ex- 

 ternally, having suturally small very feeble punctures; humeral 

 carinule much less abbreviated than in any of the preceding, sharply 

 elevated, laterally feebly sinuate behind the basal angle; legs 

 slender, very much longer in the male than in the female. Length 

 (cf, 9) 19.0-20.5 mm.; width 9.0-10.2 mm. Arizona (Sta. Rita 



M^ts., near the southern boundary) gliscans n. subsp. 



8 Body somewhat shorter and more oblong than usual, convex, aluta- 

 ceous, black, the elytra dark piceous-brown; head strongly impressed 

 transversely, with rather sparse and moderately coarse punctures, 

 becoming very fine basally; antennae with the third joint unusually 

 long, three to five rapidly and evenly decreasing, the latter one-half 

 longer than wide; prothorax fully two-fifths wider than long, evenly 

 convex and extremely minutely, sparsely punctulate, the parallel 

 sides evenly and rather strongly arcuate, the concave margins nar- 

 rower than in any other species, with moderately coarse, decidedly 

 sparse punctures; basal angles obtuse and almost obliterated, the 

 adjoining basal sinus subobsolete; elytra barely two-fifths wider 

 than the prothorax, three-fifths longer than wide, parallel and very 

 evenly rounded at the sides to the base as in gliscans, more rounding 

 posteriorly, the apical lobe distinct; humeral carinule very short, 

 slightly tortuous; surface feebly impressed along the suture, strongly 

 creased and opaculate, minutely, sparsely punctulate; legs slender. 

 Length (cf) 18.0 mm.; width 8.7 mm. Unlabeled in the Levette 



collection but probably from southern Arizona consuetus n. sp. 



Body only moderately inflated and rather convex posteriorly, with the 

 elytra only feebly flattened medially, feebly shining to rather dull 

 in lustre, black, the elytra dark piceous-brown; head feebly im- 

 pressed transversely, the punctures rather strong and close anteriorly, 

 sparse but distinct and deep elsewhere; prothorax two-fifths wider 

 than long, the parallel sides moderately rounded, feebly sinuate 

 anteriorly, the surface strongly alutaceous, with the fine sparse 

 punctulation very distinct, gradually or not very abruptly becoming 

 distinctly explanate and coarsely sparsely punctate laterally to 

 the strongly, abruptly elevated and rather thin punctulate edge; 

 basal sinus at each side very broad and feeble; elytra nearly three- 

 fourths longer than wide, in outline somewhat as in consuetus but 

 less flattened and not at all impressed suturally, more or less dull 

 in lustre, with numerous irregular creases, sometimes decidedly
