cylindrical than the preceding, and of a paler color, sparsely clothed with small, 

 white scales. Clypeus longer, with the sides more diverging, and the anterior angles'" 

 more defined ; vertex as usual with yellow hair. Thorax a little more than twice as 

 wide as long, sides almost angulated, narrowed very much in front, and moderately 

 behind, disc anteriorly without hairs, with the dorsal channel and a lateral discoidal 

 vitta (as in the next species) more densely squamous ; surface shining moderately punc- 

 tured, posterior margin fringed. Elytra shining, coarsely rugous and punctured, with 

 the suture and three vittae each side more densely squamous ; the two inner vittse ex- 

 tend within one-fourth of the apex, the outer one is less distinct, but entire, and bends 

 around the apex almost to the suture. Body beneath as in the preceding. Anterior 

 tibiae with three teeth which from wearing have become obtuse.

Kansas, Nebraska and New Mexico; shores of Tlamath Lake, Oregon, Dr. New- 

 berry ; a specimen of very large size was found by Mr. Joshua Child in the Sierra 

 Nevada of California. The head behind is clothed with moderately long hair, but 

 hardly any is seen on the thorax ; the yellow scales on the latter near the margin are 

 elongate, but on the disc they are lanceolate, and about twice as long as their width ; 

 the sides are obtusely angulated at the middle, with the posterior angles very obtuse. 

 The yellow scales of the elytra are acute, and a little more than twice as long as their 

 width. The under surface is clothed with pale scales with snowy bands across the 

 abdomen ; the pectus is very hairy, the posterior tibiae are internally clothed with 

 long hair. The feet vary from ferruginous to blackish. 



A male found in Kansas is remarkable for the right antenna bifurcating at the end 

 of the second joint ; the inner third joint is thick and short, the outer normal ; the 

 outer club is normal, but smaller than the one of the opposite side ; the inner club is 

 deformed, being composed of two which are fused together at the middle, forming a 

 concave mass, of which the upper laminae are much longer than the under ones. The 

 anterior tibiae are almost without teeth.
