378 A Preliminary Monograph of the 



59 T. facetus n. sp.— Moderately slender, rather convex, black; legs 

 piceous, the knees, tips of tibiae, and tarsi rufo-flavescent; antennae pice- 

 ous throughout; pubescence excessively fine, minute, dense although 

 inconspicuous, much sparser on the elytra and abdomen; head and pro- 

 notum alutaceous, remainder shining. Head distinctly narrower than 

 the prothorax, minutely and excessively densely punctate; prominences 

 rather large, although but moderately strong; antennae short, rather 

 slender, and extremely feebly incrassate, slightly shorter than the head 

 and prothorax; joints two to four decreasing very rapidly in length, 

 the second scarcely more robust and slightly more than twice as long 

 as the fourth, which is obconical and slightly longer than wide, tenth 

 slightly transverse; eyes moderate, rather convex, and somewhat prom- 

 inent. Prothorax about one-fourth wider than long, widest just before 

 the middle, where the sides are broadly rounded and very obtusely sub- 

 angulate, thence very feebly convergent and broadly arcuate to the 

 apex, more strongly convergent and nearly straight to the base, which 

 is but slightly over two-thirds as wide as the disk and four-fifths as 

 wide as the apex; the latter broadly, very feebly arcuate; apical angles 

 very narrowly, basal more broadly, rounded; disk broadly, evenly con- 

 vex, not impressed, but with a rather narrow, slightly tumid, impunc- 

 tate line, from before the middle nearly to the base, very minutely and 

 densely punctate. Elytra very slightly shorter than wide, slightly 

 wider near the apex than at base, about one-third wider and longer 

 than the prothorax, rather strongly impressed near the suture toward 

 base, somewhat coarsely, deeply, and densely punctate; punctures 

 three or four times as large as those of the pronotum and separated by 

 from once to twice their own diameters. Abdomen distinctly narrower 

 than the elytra and wider than the prothorax, parallel; sides feebly 

 arcuate; border moderate; surface finely and very feebly reticulate, 

 minutely and not very densely punctate. Legs slender. Length 2.2 

 mm.

Easily distinguishable by its alutaceous head and prothorax, 

 and relatively coarsely punctate elytra. 



60 T. confusus n. sp.— Slender, black; antennae throughout and 

 legs piceous-black; tarsi flavescent; pubescence very short, moderately 

 dense, and somewhat coarse; integuments somewhat shining. Head 

 slightly narrower than the prothorax, feebly convex, very finely and 

 densely punctate; prominences short, moderate; antennae slightly 

 shorter than the head and prothorax, moderately robust, distinctly in- 

 crassate, outer joints rather transverse; second joint nearly as long as 

 the next two together, fourth fully as wide as long and scarcely more 

 than one-half as long as the third; eyes rather small, convex, rather 

 prominent, coarsely faceted. Prothorax widest just before the middle,
