REVISION OF THE TENEBRIONIDiE OF AMERICA, 



scarcely confluent. The surface is also more densely clothed with an ochreous pubescence, 

 longer and much more distinct than in dilatatua or brevicollis. 



Length .20-.30 inch. 



Occurs at Fort Yuma and in Arizona. 



15. pratensis, Lee.., Col. Kansas and New Mexioo, p. 15. 



Similar in all its more important characters to lecontei; the sides of the thorax are 

 however less rounded, and the apex, more deeply emarginate, with more prominent an- 

 gles. The ochreous vestiture is liner and much less evident, the stria' of the elytra, shal- 

 lower and more finely punctured. 



Length .24-26 inch. 



Occurs in Kansas. Specimens probably of the same species are seen, deprived ol'pu- 

 besence and rather larger, from New Mexico, Texas, and Arizona. 



15. vestitus, Lee, Col. Kansas, and New Mexico, ii. 15. 



Early distinguishable from our other species by the rather dense greyish pubescence. 

 The sides of the thorax are feebly rounded and converge towards the apex. The elytral 

 stria; are faint and the punctures tine. The body above is also very faintly bronzed, a 

 character found only in the last two species in the table. 



Length .20 inch. 



Specimens reported from Kansas only. 



11. longulus, Lee., Ann. Lye. V, 147. 



'flic base of the thorax is here so feebly sinuate as compared with our other species 

 as to merit the distinction of being called nearly truncate. The thorax is as wide at 

 apex as at base, sides feebly rounded, slightly sinuate near the hind angles, which are 

 rectangular. The elytra are moderately striate with coarse punctures, the intervals feebly 

 convex and rather coarsely punctured. The form is rather elongate and the color brownish 

 black, shining. 



Length .28 inch. 



Occurs in Southern Arizona. 



15. discolor, elongate; head, thorax and legs ferruginous, elytra black, not shining. Head coarsely and 

 densely punctured, punctures elongate and confluent. Thorax broader than long, moderately convex, less coarsely 

 and densely punctured than the head ; apex i'eebly emarginate, angles not prominent; base feebly sinuate ; sides 

 feebly rounded, converging toward apex. Elytra elongate oval, convex with stria; of moderately coarse punctures of 

 which the interstices are feebly convex and finely punctured. Body beneath densely punctured. 



Length .:'(! inch. 



Easily known by its peculiar coloring. There are no signs of any pubescence. As in 

 longulus the thorax is feebly sinuate at base. The elytral striae are more faint toward 

 the base, becoming gradually more distinct toward the apex.
