508 Coleopterological Notices, VI. 



The nifile above described has the fifth ventral short and 

 broadly, feebly sinuato-truncate at apex. The female differs from 

 the male in the larger and more elongate elytra, the head and pro- 

 thorax being relatively smaller, but having nearly the same ratio 

 between themselves. Two specimens from an unrecorded part of 

 the State. 



50. T. iiiucidllS n. sp. — Obloug-oval, strongly convex, black, the legs 

 and antennte rufous, the first and eleventh joints of the latter darker; pubes- 

 cence rather short, closely decumbent, pale yellowish-cinereous in color, very 

 coarse and dense, intermingled on the elytra with a few suberect pale setse to- 

 ward the sides, coarse but a little less dense and directed obliquely backward 

 toward the middle on the pronotum ; marginal cilia somewuat short and fim- 

 briform, pale. Head two-thirds as wide as the prothorax, convex, smooth, 

 finely, sparsely punctate, the impressions very feeble; epistoma rather short 

 and transverse with a fine pale coriaceous margin ; labrum strongly rounded ; 

 eyes moderately large and prominent, not attaining the base; antenna? 1)ut 

 slightly longer than the prothorax, the outer joints moderately transverse and 

 asymmetric, fifth not perceptibly dilated. Prothorax three-fifths wider than 

 long, widest and broadly rounded at basal third, the sides thence feebly con- 

 vergent and slightly arciiate to the obtuse and widely rounded apical angles, 

 and convergent and nearly straight for a short distance to the basal angles 

 which are obtuse but evident and minutely, feebly prominent; apex subtrun- 

 cate toward the middle, much narrower than the base, the latter broadly, 

 feebly arcuate; disk minutely and relatively not densely punctate, very feebly 

 rugulose toward the sides-. Elytra one-half longer than wide, scarcely at all 

 wider than the prothorax, the sides parallel and straight; apex evenly and not 

 very broadly rounded ; disk finely and closely punctate. Ahdomtn and legs 

 densely clothed with short luteo-cinereous pubescence. Length 2.7 mm.; 

 Avidth 1.2 mm. 



California. 



The unique male type represents a species evidentl}' allied 

 closely to the two preceding, but differing in the very feebly de- 

 veloped erect setse of the elytra and in the convergent sides of 

 the prothorax. The sexual characters are feeble as usual, the 

 apex of the fifth ventral being broadly and obsoletely sinuato- 

 truncate.

Oblong, strongly convex, moderately' shining, black, the legs 

 and antennae rufous, the latter feebly obscure toward tip ; pubes-

 not concealing the surface, the inclined setae on the el3'tra only
