entire body and legs bristling with very long erect hairs, which are 

 from one-third to one-half as long as the entire width of the pro- 

 thorax ; also clothed with shorter sparse and more decumbent hairs. 

 Head rather longer than wide, coarsely and sparsely punctate, 

 with a wide impunctate median line not extending to the base, 

 the latter arcuate ; eyes large and prominent ; antennte a little 

 longer than the head and prothorax, gradually enlarged at apex. 

 Prothorax very coarsel}' punctured, a little longer than wide, 

 subequal in width to the head. Elytra large, about two-thirds 

 longer than wide and twice as wide as the prothorax, convex, the 

 omoplates not distinct. Length 3.0 mm. ; width 1.0 mm. 



Arizona (Gila River), — Cab. LeConte. I have before me a speci- 

 men from Tucson, which agrees well with the above short notes 

 which I diew up some years ago from the original type.

This is also a very distinct species, represented at present by 

 the unique t3^pe in the LeConte cabinet at Cambridge, Mass. It 

 also has the bodv clothed sparsely with long erect hairs, which 

 are one-third as long as the width of the prothorax, but the head 

 is truncate, quadrate, closely and not very coarsely punctate, 

 with a narrow impunctate line ; eyes large ; antenna? thick, a little 

 longer than the head and prothorax. Prothorax convex, the 

 sides oblique, not sinuate, a little narrower than the head and as 

 long as wide, the punctures fine but deep, even, rather close but 

 distinctly separated. Elytra twice as long as wide, not quite 

 twice as wide as the prothorax, the punctures strong but not re- 

 markably coarse, separated by nearly twice their own diameters. 

 Length 2.5 mm.; width 0.8 mm. 



California (San Diego). I have not had an opportunit}^ to ex- 

 amine this species for generic characters of the mesosternum, but 

 infer that it is properl}' placed here, in spite of its resemblance 

 in form to vicinus, as related by LeConte.

Polished, pale testaceous, the elytra each with a large subcircu- 

 lar spot at apical fourth of paler flavate, which is usually rendered 

 still more obvious by blackish anterior and posterior margins ; 

 pubescence rather long, coarse, sparse, equal and posteriorly re- 

 curved, cinereous in color. Head coarsely punctate, with a
