than the prothorax, gradually obtusely ogival in nearly apical half; 

 coarse deep sutural stria almost but not quite attaining the base; 

 foveae at basal third and just behind the middle. Length 1.9-2.3 

 mm.; width 0.75-0.9 mm. Texas (Austin, Waco and Houston). 



soror n. sp. 



Form more oblong-suboval and not quite so convex, pale testaceous 

 throughout, the paler nubilosity of the elytra so faint as to be in- 

 distinct; head three-fifths as wide as the prothorax, the eyes moder- 

 ate; anterior strioles short and feeble; antennae nearly two-thirds as 

 long as the elytra, feebly and gradually incrassate, slender basally 

 as usual; prothorax nearly one-half wider than long, widest near 

 apical two-fifths; base slightly wider than the apex; sides strongly 

 rounded, straight basally, the angles minutely subprominent; sub- 

 basal arcuate punctate sulcus distinct laterally, the three medial 

 punctures isolated and distinct; foveae small; margins very finely 

 reflexed: elytra one-half longer than wide, two-fifths wider than the 

 prothorax, rapidly obtusely ogival behind, the parallel sides arcuate, 

 very gradually rounding basally, the humeri not exposed at base 

 beyond the thoracic base; coarse sutural stria abbreviated in basal 

 seventh; foveae small, near basal and apical third. Length 2.0 

 mm.; width 0.9 mm. New Mexico (Jemez Springs), Woodgate. 



monticola n. sp. 



Form broader and more parallel, convex, polished, castaneous, each 

 elytron with two large nubilous areas of paler tint; head larger than 

 in soror, though barely more than half as wide as the prothorax, the 

 eyes moderate, rather prominent; short anterior sulci distinct; an- 

 tennae three-fifths as long as the elytra, yellow and slender basally, 

 fuscous and very feebly incrassate distally; prothorax large and very 

 convex, nearly one-half wider than long, widest barely before the 

 middle, the sides strongly rounded, moderately reflexed; surface 

 with the three subbasal punctures isolated and distinct; elytra 

 scarcely one-half longer than wide and about a third wider than the 

 prothorax, parallel, feebly arcuate at the sides, obtusely parabolic 

 at apex; deep sutural stria distinctly abbreviated at base: foveae 

 very small, at about third and three-fifths. Length 2.5 mm.; width 

 i.o mm. Mississippi (Vicksburg). [T. incurvus Lee. nee Say]. 



nebulosa Chd. 



Form and coloration somewhat as in nebulosa but less broad and fre- 

 quently nearly black, in which case the elytral paler areas are often 

 inconspicuous and still more nubilous; head larger than in soror, 

 though scarcely over half as wide as the prothorax, the anterior 

 short sulci minute and fine; eyes well developed and rather prom- 

 inent; antennae as in nebulosa; prothorax relatively not quite so 

 large as in the latter species, not one-half wider than long, widest 

 rather distinctly before the middle, the sides strongly, evenly 

 rounded, feebly sinuate basally, the angles sharp and subprominent; 

 three subbasal discal punctures strong and clearly isolated; base 

 wider than the apex as usual; elytra one-half longer than wide and 

 fully two-fifths wider than the prothorax, broad, oblong-suboval, 

 gradually ogival in nearly posterior two-fifths; sides parallel, arcu-
