Kortli American Species of Trogophloeus, 383 



The impressions of thepronotum are long, closely approximate 

 and nearly straight. In tantillus andfilutn they are strongly, 

 inwardly arcuate, and, in the latter very much deeper. 



66 T, tantillus n. sp. — Very slender, linear, slightly convex, black; 

 elytra pale, rufescent; legs pale, flavate; antennae pale brown, flavate 

 at base; pubescence fine, rather short, and very dense; integuments 

 feebly shining. Head very slightly narrower than the prothorax, feebly 

 convex, minutely, feebly, and very densely punctate; prominences 

 small but strong, separated by one-half the total width; eyes large, con- 

 vex, prominent; antennae slender, feebly incrassate, very distinctly 

 longer than the head and prothorax; joints two to four decreasing 

 moderately in length, the fourth scarcely longer than wide, tenth nearly 

 as long as wide. Prothorax widest at anterior third, where the sides are 

 rather broadly, evenly arcuate and coarctate to the apex, rather feebly 

 convergent, and very slightly arcuate to the base, which is feebly arcu- 

 ate, four-fifths as wide as the disk, and very slightly narrower than the 

 apex; the latter very feebly arcuate; apical angles obtuse and scarcely 

 at all rounded; disk feebly convex, one-fifth wider than long, very 

 minutely, densely punctate, with two longitudinal arcuate and moder- 

 ately feeble approximate impressions, without median impunctate line. 

 Elytra as long as wide, one-fourth wider and two-fifths longer than the 

 prothorax, feebly impressed near the suture toward base, minutely and 

 rather densely punctate; punctures not larger, although slightly more 

 distinct than those of the pronotum. Abdomen rather distinctly nar- 

 rower than the elytra, parallel; sides nearly straight; border moderate, 

 shallow; surface finely, feebly reticulate, minutely and densely punc- 

 tate. Legs slender; femora compressed and slightly arcuate. Length 

 1.8 mm. 



Texas (Austin 4). 



A small linear species which is very distinct. The coarse tac- 

 tile setae, one just over the eye anteriorly, another just behind, 

 over and more distant from the eye, one at the apical angle of 

 the prothorax, and another at the lateral edge at posterior third, 

 are more than ordinarily developed. On the other hand the two 

 discal set98, mentioned under the description of iipuncticollis, 

 do not seem to exist at all. In the latter all the lateral setsehere 

 mentioned exist, as usual, but are very much less developed than 

 in tantilluSy the habits of life, perhaps, tending rather to the de- 

 velopment of the two dorsal setae.
