evenly 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 differs much in its longer 

 eh'tra, longer coarser denser and more confusedU' denuded pu- 

 bescence, less transverse prothorax and other features. 



20. L.. tritus n. sp. — Narrow, elongate aud convex, the integiiments 

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

 and snbdecumbent cinereous hairs, which are generally not at all denuded on 

 the elytra except in a few spots behind the middle, of which four arranged 

 transversely in the isosition of the usual fascia at apical fourth are jiarticularly 

 evident. Head fullj' three-fourths as wide as the prothorax, the neck rather 

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

 tures moderately sparse, the interspaces coai'sely rugose biit polished ; subapi- 

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

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

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

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

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

 opaque under low power ; punctures moderately close, the interspaces sti'ongly 

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

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

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

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

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

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



California ( Lake Co.). 



The three males before me represent a close all}' of difficilis, but 

 can be specificalh' distinguished bv the more elongate body 

 clothed with longer, denser and much coarser pubescence, the 

 latter being denuded in definite areas only behind the middle. 

 From Jidelis it also differs in this last character, and in its 

 smaller e3'es 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. L,. confllSUS n. sp. — Elongate-oval, moderately convex, black Avith 

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

 tennfe piceous-black, the second joint paler 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 Avith 

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