-2.4 mm.; width 0.85-1.0 mm. Two examples, unlabeled in the 

 Levette collection and probably from Indiana vernicata n. sp. 



Body shorter and much stouter than in incnrva, paler in color as a rule, 

 the ground tint castaneous, the paler elytral areas similarly distinct; 

 head four-sevenths as wide as the prothorax, the eyes only moderate 

 in size but notably prominent; anterior frontal impressions somewhat 

 longer than usual; antennae almost as in -incurva but longer, paler 

 and more slender, fully two-thirds as long as the elytra; prothorax 

 remarkably large, two-fifths wider than long, the base much wider 

 than the apex as usual, widest near anterior two-fifths; sides ante- 

 riorly rather broadly, not very strongly rounded, moderately oblique 

 and nearly straight in almost basal half; subbasal sulcus moderate, 

 the medial puncture strong, isolated, from it extends to about apical 

 fourth the very fine medial stria; foveae small and rather deep; ely- 

 tra barely one-half longer than wide, sometimes less, about a fourth 

 wider than the prothorax, obtusely parabolic at apex; coarse sutural 

 stria not quite, though nearly, attaining the base; outside of it a 

 feeble abbreviated stria is generally observable under oblique illumi- 

 nation; fovese very small, at two and four sevenths. Length 1.9- 

 2.2 mm.; width 0.7-0.9 mm. Texas (Austin, Waco and Houston) 

 and Mississippi (Vicksburg) congener n. sp. 



12 Form rather narrow, elongate-suboval, strongly convex, highly pol- 

 ished, uniform pale testaceous-brown throughout, the legs more 

 flavate; head rather more than three-fifths as wide as the prothorax, 

 the eyes moderate but prominent; anterior strides very minute; 

 antennae fusco-testaceous, a little clearer basally, three-fifths as long 

 as the elytra; prothorax large, one-half wider than long, widest at 

 about the middle, the sides strongly and subevenly arcuate, nearly 

 straight basally, the angles sharp, scarcely prominent and more than 

 right; subbasal impressed line completely impunctate, the medial 

 puncture evident, subisolated; foveae small, distinct, distant from 

 the angles as usual; elytra fully one-half longer than wide, scarcely 

 a third wider than the prothorax, parallel, evenly parabolic in about 

 apical third; deep sutural stria abbreviated in basal sixth or seventh; 

 outside the sutural stria a second extremely fine line is sometimes 

 glimpsible; fovese behind basal and before apical third. Length 1.9 

 -2.2 mm.; width 0.75-0.83 mm. New Jersey and Virginia (Nor- 

 folk). [ Tachys fuscicornis Hayw. nee Chd.] gemella Csy. 



Form parallel or oblong-suboval, very small in size, convex, highly pol- 

 ished and sculptureless, pale yellowish-brown throughout, the legs 

 and under surface still paler; head feebly infumate, notably small, 

 barely over half as wide as the prothorax, the anterior strides short 

 but distinct; eyes very moderate in size and convexity; antennae 

 scarcely two-thirds as long as the elytra, blackish and incrassate 

 distally, more slender and flavescent basally; prothorax relatively 

 larger than usual, three-fifths wider than long, wider at base than 

 at apex, the sides broadly and feebly arcuate throughout, slightly 

 straighter posteriorly, the angles obtuse but not rounded; subbasal 

 sulcus interrupted medially, with a single strong puncture in the 

 interval: elytra oblong-oval, very gradually rounded behind, the
