evenl}^ truncate at apex, about one-third longer than the fourth, 

 with its surface completely unmodified and clothed with the usual 

 decumbent ashy pubescence. 



This species is allied to difficilis, agreeing in the general char- 

 acter of the sexual modifications, but diflfers much in its longer 

 elytra, longer coarser denser and more confusedly denuded pu- 

 bescence, less transverse prothorax and other features. 



"20. L.. tritlis □. sp. — Narrow, elongate and convex, the integuments 

 black, shining and slightly brassy bnt densely clothed with rather long coarse 

 and subdecumbent cinereous hairs, Avhich are generally not at all denuded on 

 the elytra excejit in a few spots behind the middle, of which fonr arranged 

 transversely in the position of the usual fascia at apical fourth are particularly 

 evident, ffend fully three-fourths as wide as the prothorax, the ueck rather 

 strongly narrowed ; eyes moderate in size but decidedly prominent ; punc- 

 tures moderately sparse, the interspaces coarsely rugose but polished ; subapi- 

 cal impressions feeble ; antennae slender, nearly one-half longer than the pro- 

 thorax, piceous-black, the second joint paler, tenth rather longer than Avide. 

 Prothorax two-fifths wider than long, parallel and evenly arcuate at the sides 

 in basal half, thence strongly convergent and straight to the obtusely rounded 

 apical angles, the serrulation very fine and feeble ; apex feebly arcuate ; disk 

 opaque under low power ; punctures moderately close, the interspaces strongly 

 rugose but polished, more evidently and coarsely rugose as usual in rather less 

 than lateral fourth. Elytra long, four-fifths longer than wide, quite distinctly 

 wider than the prothorax, parallel and straight at the sides, narrowly para- 

 bolic in apical third or fourth ; disk rather coarsely, deeply and closely punc- 

 tate. Under surface finely pubescent as usual, the legs black throughout. 

 Length 2.8-.3.0 mm; width 0.9-1.1 mm. 



California ( Lake Co.). 



The three males before me represent a close ally o^difficilis, but 

 can be specifically distinguished by the more elongate body 

 clothed with longer, denser and much coarser pubescence, the 

 latter being denuded in definite areas only behind the middle. 

 From fi.delis it also differs in this last character, and in its 

 smaller eyes and more opaque and rugose sculpture of the pro- 

 notum. The fifth ventral is about one-half longer than the 

 fourth, truncate at apex and unmodified on the disk. 



•21. Lf. confusiis n. sp. — Elongate-oval, moderately convex, black with 

 a feeble reneous lustre on the elytra; legs black, the tarsi slightly pale; an- 

 tenna- i)iceous-l)lack, the second Joint i)aler and piceo-testaceous; pubescence 

 rather long, suberect; moderately coarse, not very dense, consisting of cinereous 

 hairs which, on the elytra, are brownish in certain small scattered spots with 

 indefinite boundaries, brown toward the middle of the pronotum except along
