moderately inorassate, the tenth joint distinctly longer than wide. Prothorax 

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

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

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

 close but distinctly separated. Khjfra large, scarcely two-thirds longer than 

 wide, distinctly' more than twice as wide as the prothorax, evidently wider just 

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

 liumeri widely exposed; omoplates large and subobsolete; punctures coarse, 

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

 Abdomen polished, li,neh% closely ])unctate, the metasternum more coarsely and 

 sparsely. Le^s rather long and slender; femora moderately stout; coxae dark 

 rufous. Length 3.9 mm.; width 1.3.5 mm. 



Utah (southwestern). Mr. Weidt. 



The single female represents a form closely related to biguttulus, 

 but differing in the characters heretofore stated. It is possible 

 that the elytra may liave been accidentally denuded in this speci- 

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

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

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

Elongate, convex, black, the tibifc and tarsi paler ; antenme 

 black throughout; head and prothorax glabrous, the elytra 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, finely 

 but strongh', sparsely punctate, with a narrow and entire impunc- 

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

 raoderatel}' incrassate, the tenth joint not longer than wide. 

 Prothorax distinctly narroAver than the head, a little longer than 

 wide, very convex, widest and broadl}' 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. El3'tra very long, twice as long 

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

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

 broadly rounded ; post-scutellar impression wide and distinct ; 

 omoplates subobsolete; disk polished, sparsely, very coarsely 

 and deeply punctured. Abdomen finely, moderately sparsely
