long, wide, truncate; labium obtusely ogival at apex, bristling with long setic; 

 eyes rather large and convex, not quite attaining the base; antennae broad and 

 compressed, a little longer than the prothorax, the penultimate joints very 

 strongly transverse. Prothorax two-thirds wider than long, the sides sub- 

 parallel, evenly and moderately arcuate from base to apex, the latter l)roadly 

 arcuate with a very obsolete entering angle at the middle, the apical angles 

 obtuse and rounded; basal angles, obtuse but not rounded and minutely, feebly 

 prominent; base arcuate; disk minutely and sparsely punctate, smooth and 

 polished throughout. Efi/tra scarcely one-half longer than wide and only just 

 visibly wider than the ijrothorax, parallel, evenly rounded at apex, rather 

 finely but strongly and closely punctate. Length 2.6-3.2 mm.; width 1.15- 

 1.45 mm.

The description refers to the male, in which sex the intromit- 

 tent organ is in the form of a flattened cylindrical sheath, ob- 

 liquely truncate at apex, with the inferior surftice produced at tip 

 in a fine slender cusp-point. In the female the head is not more 

 than two-thirds as wide as the prothorax. Numerous specimens. 



Several specimens apparently" not differing otherwise, have the 

 legs and antenna? rufous throughout, the apical joint of the latter 

 blackish. 



49. T. sobi'iiius n. sp. — Oblong-suboval, moderately convex, polished 

 throughout, the head and pronotum not at all rugose even at the sides, black; 

 legs and antennne rufous, the eleventh joint of the latter dusky; pubescence 

 ochreo-cinereous, moderately long and coarse, dense and intermingled with 

 erect, pale and coarse hairs on the elytra, more decumbent and sparser anteri- 

 orly ; marginal cilia pale, somewhat long, dense and fimbriform on the protho- 

 rax, scarcely longer but more distant on the elytra. Head three-fifths as wide 

 as the prothorax, convex, minutely and sparsely iiunctate, the frontal impres- 

 sions very feeble; epistoma rather long and narrower than usual, pale and 

 coriaceous; labrum almost as long as wide, strongly and nearlj' evenly rounded 

 and pale at apex; eyes rather large, slightly prominent, not attaining the base, 

 the tempora behind them opaque and asperate; antenna' somewhat stout, dis- 

 tinctly longer than the prothorax, the i)enultimate joints strongly transverse, 

 fifth not dilated. Prothorax nearly three-fourths wider than long, parallel and 

 very feebly arcuate at the sides to Ijasal third, tliere more prominently rounded 

 and thence more convergent and nearly straight to the basal angles, which are 

 obtuse but distinct and minutely prominent; apical angles oljtuse and ))roadly 

 rounded; apex and base broadly arcuate; disk minutely and sparsely punctate. 

 Elytra not cjuite one-half longer than wide, sciircely perceptibly wider than 

 the prothorax, parallel, evenly rounded at apex, finely and closely i)unctate.
