flexed, the prothorax widest slightly before the middle, the thin 



edges not or only very feebly crenulate 4 



4 Scutellum equilatero-triangular, nearly flat; apical angles of the pro- 

 thorax rounded, not at all everted. Form moderately stout and 

 convex, piceous-black, the elytra rufous, clouded with piceous later- 

 ally; head feebly impressed, the punctures distinct, moderately 

 close-set, each with the very minute hair pale and evident; pro- 

 thorax one-half wider than long, the sides and base as usual, the 

 latter broadly arcuate, with the broad feeble median sinus rather 

 distinctly limited; punctures fine and sparse, the surface broadly, 

 evenly, rather feebly convex, gradually becoming coarsely but 

 loosely punctate in the lateral concavity, the moderately wide, 

 strongly reflexed sides transversely rugose and coarsely punctate; 

 elytra ( 9 ) sensibly less than twice as long as wide, one-half wider 

 than the prothorax, evenly oval, evenly but only moderately convex 

 above, feebly depressed narrowly along the suture, the sides of the 

 base feebly prominent, the surface alutaceous, the feebly convex 

 lines separated by broad rugose intervals, over which are scattered 

 sparse fine punctures, the third and fourth intervals more convex 

 and not so broad, the lateral margin rather acute and well marked; 

 abdomen occupying fully half the entire length, minutely, sparsely 

 punctate; legs nearly as in inferna. Length ( 9 ) 25.0 mm. ; width 1 1.5 

 mm. Kansas (Gove Co., 2500 ft.), F. H. Snow, .compar n. sp. 

 Scutellum longer than wide, acutely pointed, not tumid; apical angles of 



the prothorax everted and more or less prominent 5 



5 Body large, much elongated, convex, shining, piceous-black, the 

 elytra dark rufous, dusky at the sides; head deeply, obliquely 

 bi-impressed, finely, sparsely punctate; prothorax nearly as in compar 

 but with the apical angles acutely everted and prominent; scutellum 

 nearly twice as long as wide, very acute; elytra fully twice as long 

 as wide, oval, convex, gradually acute behind, the surface but very 

 faintly alutaceous, the rather wide convex lines separated by in- 

 tervals which are only a little wider than themselves, quite as convex 

 and only very feebly rugulose, the small and sparse punctures through- 

 out irregular in size and shape, some being rather elongate, this 

 character being more marked than in compar; abdomen shining, 

 very obsoletely rugulose, minutely and remotely punctate; legs 

 long and slender, the hind tibiae evenly and feebly bowed; hairs on 

 the under side of the tarsi long and deep fulvous-red. Length 27.5 

 mm.; width 1 1. 8 mm. Texas and New Mexico. [Pelecyphorus elatus 



Lee.] elata Lee. 



A As in elata but smaller and more slender, the elytra more evidently 

 striate, black; prothorax slightly shorter than wide, the sides 

 broadly and gradually reflexed, rounded anteriorly, angulate in 

 the middle, and, thence to the base, sinuate; base truncate, the 

 posterior angles almost right; surface medially sparsely and finely, 

 laterally more coarsely and rugosely, punctate; elytra slightly wider 

 than the prothorax, elongate-oval, acuminate behind, moderately 

 deeply punctato-scabrous; striae distinct, broad, moderately
