Stout, blaciv, the elytra througliout pale rufous ; integuments 

 polished; pubescence in great part denuded in the type but ap- 

 parently rather short, sparse and comparatively inconspicuous, 

 erect along the sides of the body; antennne short, incrassate, the 

 outer joints transverse. Prothorax three-fifths wider than long, 

 the sides parallel and broadly arcuate ; apical and basal angles 

 broadly rounded; disk evenly convex, finely and sparsely punc- 

 tate. Elytra one-fourth wider than the prothorax and three 

 times as long, nioi-e coarsely and strongly and a little more 

 closely though still not densely punctured. Length 5.5 mm.; 

 width 2.3 mm. 



Arizona (Gila.) The only known specimen is the unique type 

 in the cabinet, of LeConte, from which the above superficial 

 notes were taken a few years since. It may be recognized by its 

 unusually large size and l)y its coloration.

 the tibi;e and tarsi infescent; anteniiiX' black, the funicle slightly rufescent 

 toward 1)ase; pubescence cinereous, siibdecunibent, rather long and dense, in- 

 termingled Avith a few long blackish set:^ toward the sides of the i)ronotuni, 

 the erect hairs of the elytra very coarse and abinidant hut only nioderatelj' 

 long, inclined posteriorly and cinereous, longer at the margins. Head three-

 labrum short and transverse though large, very broadly rounded; eyes rather

 three-fifths wider than long, the sides i^erfectly i)aralk'l and very feebly arcuate 

 almost throughout, feebly sinuate toward the basiil angles which are obtirse 

 but distinct, the base obliiiuely sinuate for a short distance near the angles, 

 l)roadly and strongly arcuate in the middle; apex broadly arcuato-truncate, 

 fully as wide as the base or slightly wider, the apical angles but slightly ob-
