ally convergent from the base, and with short mandibles and 

 labrum ; it probably represents a closel}" allied species. 



31. T. nilltilatiis n. sp. — Rather nanow and convex, polished, black, 

 the prothorax with a feeble seneous lustre; elytra pale rufo-ferniginoiis, with 

 a large and indefinite sntnral cloud of blackish in about basal half; abdomen 

 black, the fifth segment and following i^ale; legs pale rufous throughout; anten- 

 nje black, the funicle feebly testaceoiis toward base; pubescence moderately 

 long, dense and coarse, pale luteo-cinereous in color. Head nearly four-fifths 

 as wide as the prothorax, finely, sparseh* punctate, the frontal impressions 

 feeble; epistoma short, depressed and thin but black and corneous; labrum 

 semi-circular, with a few small scattered setigerous punctures; mandibles rather 

 long, pale, black at tip; eyes lai-ge and somewhat prominent; antenna; nearly 

 two-fifths longer than the prothorax, bristling with short stiff setse especially 

 within, the fifth joint dilated, tenth slightly transverse and somewhat asjan- 

 metric. Prothorax two-fifths wider than long, the sides evenly and feebly 

 convergent from base to apex and evenly, feebly arcuate; basal angles broadly 

 rounded, the apical obtuse and greatly deflexed; apex arcuato-truncate and 

 distinctly narrower than the base; disk polished, obsoletely reticulate, not 

 scabrous laterally, finelj^ and sparsely punctate. Elytra one-half longer than 

 wide, fully two-fifths wider than the prothorax, parallel and straight at the 

 sides, broadly rounded at apex; humeri slightly exposed at base; disk finely, 

 rather densely and not very distinctly punctate. Legs somewhat long and 

 slender. Length 2.3 mm. ; width 0.8 mm. 



California (Lake Co.). 



The unique tj'pe of this species is a male and has the fifth ven- 

 tral rectilinearly truncate at apex, with the surface polished and 

 almost impunctate save a few piliferous punctures in the middle 

 toward base ; the genital segment is large, flat, truncate at apex, 

 the latter with a beveled coriaceous edge, the surface feebl}- di- 

 vided along the median line ; the fourth segment, and, to a less 

 degree the third, has a cluster of coarse punctures in the middle 

 toward apex, which bear short pointed spiniform and inclined 

 seta? which radiate in direction from the median line. This spe- 

 cies is readily distiuguishable from umhratus by its dense and 

 coarse vesiture and nubilate maculation. 



32. T. suffllSllS n. sp. — Moderately stout and convex, shining, black, 

 the elytra i>ale luteo-testaceous, broadly and suffusedlv black toward the 

 suture except toward apex ; abdomen with only the extreme apex of the fifth 

 segment pale; legs pale rufous throughout; antenna; dark piceo-rufous; pubes- 

 cence rather fine, moderately long and sjaarse, cinereous, the scutellum thinly 

 pubescent. Head two-thirds as wide as the prothorax, finely, sparsely punc- 

 tate, the impressions large and feeble; epistoma very short and broad, with a
