354 REVISION OF TlIK TENEBKIONIDjE OF AMERICA, 



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

 longer and much more distinct than in dilatatvs or bremcollis. 



Length .2 I-.30 inch. 



Occurs at Foil Yuma and in Arizona. 



15. pratensis, Lee, Col. Kansas and New Mexico, 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 dura shal- 

 lower and more finely punctured. 



Length .24-. 26 inch. 



Occurs in Kansas. Specimens probably of the same species arc seen, deprived ofpu- 

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



B. vestitus, Lee., Col. Kansas, and New Mexico, p. 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 elytra! 

 stria' are faint and the punctures fine. 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. 



]!. lougulus, Lee, Ann. Lye. V, 147. 



The baseof'tlie thorax is here so ieebly 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. 



li. discolor, elongate; head, thorax ami lugs 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 feebly emarginate, angles not prominent; base feebly sinuate ; sides 

 feebly rounded, converging inward apex. Elytra olongate oval, convex with strise of moderately coarse punctures of 

 which tin- interstices are feebly convex and finely pum-tiiivd. Liody beneath densely punctured. 



Length .36 inch. 



Easilj known by its peculiar coloring. There tire no signs of any pubescence. As in 

 longulus the thorax is ieebly sinuate at base. The elytra! stria* are more faint toward 

 the base, becoming gradually more distinct toward the apex. 

 \ single specimen trom near Visalia, California.
