moderately incrassate, the tenth joint distinetly lonj^er than wide. Profhorax 

 scarcely narrower than the head, as lonj^ as wide, convex, widest and rather 

 strongly rounded at anterior third, the sides thence moderately convergent and 

 jnst visibly arcnate to the basal margin; ptinctures somewhat coarse, deep and 

 close but distinctly separated. Elytra large, sparoely two-thirds longer than 

 wide, distinctly more than twice as wide as the prothorax, evidently wider jnst 

 behind the middle than at base; sides arcnate; apex not very broadly rounded; 

 humeri widely exposed; oniO]dates large and sn})obsolete; punctures coarse, 

 deep and well separated, but slightly smaller and more distant toward apex. 

 Ahdomin polished, finely, closely punctate, the metasternum more coarsely and 

 sparsely, /.cr/.s rather long and slender; femora moderately stout; coxa; dark 

 rufous. Length 3.9 mm. ; width l.:?.") mm. 



Utah (southwestern). Mr. Weidt. 



The single female represents a form closely related to biguttulus, 

 but ditfering in the characters heretofore stated. It is possible 

 that the elytra ma^- haA'e been accidentally denuded in this speci- 

 men, but it is difficult to imagine how this could have been ef- 

 fected so uniformly, not a single'long hair remaining, except the 

 usual series af erect tactile setie along the flanks toward base.

Elongate, conVex, black, the tibije and tarsi paler; antennte 

 black throughout; head and prothorax glabrous, the el3'tra with 

 extremely short, remote and decumbent hairs. Head subquad- 

 rate, parallel, slightly transverse, the base truncate, strongly im- 

 pressed in the middle ; eyes small ; tempora long and parallel ; 

 angles rounded ; surface moderately convex, alutaceous, finel}^ 

 but strongly-, sparsely i)unctate, with a narrow and entire impunc- 

 tate line ; antenuic rather longer than the head and prothorax, 

 moderately incrassate, the tenth joint not longer than wide. 

 Prothorax distinctly narrower than the head, a little longer than 

 wide, very convex, widest and broadly rounded at apical two- 

 fifths, the sides thence gradually' feebly convergent to a rounded 

 feeble constriction near the base, the latter wholly devoid of 

 beaded margin; collar broad but distinct; surface alutaceous, finely 

 but strongly, sparsely punctured. Elytra ver}" long, twice as long 

 as wide, twice as wide as the prothorax, three-fourths Avider than 

 the head, the sides parallel and evenly arcuate; apex rather 

 broadly rounded ; post-scutellar impression wide and distinct ; 

 omoplates subobsolete ; disk polished, sparsely, ver^^ coarsely 

 and deeply ])unctured. Abdomen finely, moderately sparsely
