ruginons thronghont, the head piceous-black ; pubescence rather fine and even, 

 somewhat short, moderately close, brownish-cinereous in color. Head nearly 

 four-fifths as wide as the prothorax, exactly equal in width to the anterior 

 margin of the latter, finely, somewhat closely punctate and slightly rugulose, 

 the anterior impressions rather feeble but distinctly defined by the somewhat 

 prominent supra-antennal ridges and separated by a smooth impunctate con- 

 vexity at apex ; epistoma pale and coriaceous throughout ; labrum almost semi- 

 circularly rounded; mandibles pale toward base; eyes scarcely at all promi- 

 nent; antennte slender, about as long as the prothorax, not in the least incras- 

 sate toward tii), the fifth joint distinctly dilated, the tenth transverse and al- 

 most completely symmetrical. Prothorax long, not quite one-tliird wider than 

 long, widest at basal third where the sides are very feebly prominent, thence 

 distinctly convergent and almost straight to the apex and feebly so for a very 

 short distance to the basal angles, which are extremely obtuse but scarcely at 

 all rounded; apical angles obtuse and rounded; apex arcuato-truncate, the base 

 broadly arcuate; disk minutely, sparsely punctate, only slightly rugulose near 

 the sides, marginal fringe short and close. Elytra three-fifths longer than 

 "wide, nearly one-third wider than the prothorax, parallel and nearly straight 

 at the sides, very obtusely rounded at apex, the humeri narrowly rounded and 

 slightly tumid; punctures rather fine l)ut distinct and somewhat close-set. 

 Abdomen finely and not very densely cinereo-puljescent, the legs very slender, 

 the femora finely and closely punctulate. Length 2.5 mm. ; width 1.0 mm. 



California (San Mateo). 



A distinct species, identiSable at once by the elongate and 

 apically narrowed prothorax which is much narrower than the 

 elytra, brownish pubescence and slender red legs. The single 

 specimen before me is not obviously determinable in regard to 

 sex. 



22. T. pildens n. sp. — Narrowly oblong, somewhat convex, moderately 

 shining, black, the legs and antennse pale rufo-ferruginous, the last joint of 

 the latter somewhat obscure; integuments feebly reticulate throughout, becom- 

 ing subrugose toward the sides of the prothorax ; pubescence rather fine and 

 sparse anteriorly but very coarse and somewhat dense, pale ochreo-cinereous 

 and closely decumbent on the elytra. Head rather small, scarcely more than 

 three-fifths as wide as the prothorax, riigulose toward base but very minutely 

 and almost imperceptibly punctate throughout, the anterior impressions large 

 and strong, the median convex surface large and smooth ; epistoma piceous 

 and subcoriaceous ; labrum short, pale, almost semi-circiilarly rounded; eyes 

 not very large and somewhat prominent; antenna; very slender, scarcely 

 longer than the prothorax, the first two joints much stouter, fifth distinctly 

 dilated, last three rather abruptly larger and incrassate among themselves, the 

 tenth transverse. Prothorax one-half wider than long, widest at basal third 

 where the sides are parallel and broadly arcuate, l)ecoming gradually rather 

 strongly convergent and very feebly arcuate anteriorly to the ol)tuse but evi-
