rnfiinous thioiijiliout, tlie head i>iceous-black; pubesceuce ratluT fine and even, 

 sonifwliat short, niodorately close, Tnownish-cinereous in color. Hc<id nearly 

 I'our-Hfths as wide as the prothorax, exactly etjual in width to the anterior 

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

 the anterior impressions rather feeble but distinctly defined ))y 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; antennic slender, about as long as the prothorax, not in the least incras- 

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

 most completely symmetrical. Profhora.v long, not quite one-third wider than 

 long, widest at basiil 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 l)asal 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 

 Avide, 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 birt distinct and somewhat close-set. 

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

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



California (San Mateo). 



A distinct species, identifiable 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 obbmg, somewhat convex, moderately 

 shining, black, the legs and antennae 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, ])ale ochreo-cinereous 

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

 three-fifths as wide as the prothorax, rugulose 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-circularly rounded: eyes 

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

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

 dilated, last three rather abrui)tly larger and incrassate anumg themselves, the 

 tenth transverse. Pi-Dfhoni.r one-half \\ider than long, widest at basal third 

 where the sides are parallel and broadly arcuate, becoming gradually rather 

 strongly convergent and very feebly arcuate anteriorly to the obtuse but evi-
