or less testaceous; pubescence pale yello\visli, moderate in lenj^th, rather 

 coarse, dense throughout, the longer pale hairs of the elytra scarcely evident, 

 being much inclined; marginal cilia very short, dense, recurved and finibri- 

 form on the prothorax, very much longer and sparser on the elytra. Head 

 barely three-fifths as wide as the prothorax, convex, minutely, sparsely punc- 

 tate, smooth and polished throughout, the frontal impreasions very feeble; 

 epistt)ma elongate, less than one-half Avider than long, pale; labrum about as 

 as long as wide, acutely i)arabolic at apex; eyes large but not prominent; an- 

 tenuic as long as the prothorax, feebly incrassate, the penultimate joints 

 m(Hlerately transverse, fifth scarcely dilated. Prothorax two-thirds Avider than 

 long, the sides feel)ly convergent from base to apex and feebly arcuate, more 

 distinctly though broadly so behind the middle; apex rectilinearly truncate, 

 anteriorly oblitjue at the sides, the angles acute and sc*arcely ])lunt; basal 

 angles l)roadly obtuse but distinct; disk minutely and sparsely punctate; in- 

 terspaces smooth and polished, not in the least rugose at the sides. Elytra 

 three-fourths longer than wide, scarcely visibly wider than the prothorax, 

 parallel and straight at the sides, semi-circularly rounded at apex, finely and 

 densely punctate, the interspaces smooth, slightly rugiform as usual by anteri- 

 orly oblique light. Ahdomen finely, densely punctulate, densely cinereo-pu- 

 bescent, the legs moderately long. Length 3.U mm.; width 1.2 mm.

This distinct species is represented before me by a single 

 female from an unknown part of the Territory. The longer hairs 

 of the elj'tra are so mnch inclined and so indistinct that their 

 presence might readily be overlooked, and the species assigned 

 to the preceding subdivision of the genus. 



45. T. fililbl'iatus n. sp. — Oblong, parallel, evenly convex, piceous- 

 black; legs and antenn;e blackish throughout; vestiture moderately long, 

 coarse, dense throughout, bright fulvous in color, the elytra Avith long, erect, 

 very coarse and conspicuous settc of the same color, uniformly distributed over 

 the entire surface; marginal cilia rather short, very dense, reclined and fim- 

 briforra on the prothorax, much longer on the elytra, pale. Head three- 

 fourths as Avide as the prothorax, convex, finely but strongly, sparsely punc- 

 tate; interspaces smooth and polished throughout; frontal impressions almost 

 obsolete; epistoma extremely short and broad; labrum strongly rounded; eyes 

 large but only moderately prominent; antennie distinctly longer than the pro- 

 thorax, rather slender, feebly incrassjvte, the penultimate joints moderately 

 trajisverse, fifth scarcely at all dilated. Prothorax twice as Avide as long, the 

 sides prominently roundid behind the middle, convergent and feebly arcuate 

 thence to the obtuse and rounded apical angles, and still more convergent and 

 straight to the basiil angles, Avhich are very obtuse and indistinct; apex trun- 

 cate, Avith a very broad and ob.solete entering angle at the middle, as Avide as 

 the base; disk finely but strongly, sparsely punctate; intersiKices smooth and 

 polished, l>ut slightly rugose near the sides. Elytra fully one-half longer than 

 wide, not at all Avider than the Avidest part of the prothorax, parallel, serai-
