346 A Preliminary Monograph of the 



finely, densely punctate, shining, the punctures distinctly separated;^ 

 prominences small, moderate; antennae much longer than the head and 

 prothorax, very slender and very feebly incrassate; joints two to four 

 decreasing very slowly in length, elongate, tenth very decidedly longer 

 than wide; eyes very large, prominent; tempora very short, less than 

 one-third as long, strongly rounded. Prothorax widest at anterior 

 third, where the sides are rather strongly, evenly rounded, thence nearly 

 equally and rather strongly convergent to base and apex, straight in 

 the former sense, feebly arcuate in the latter; base feebly arcuate, two- 

 thirds as wide as the disk, much narrower than the apex; the latter 

 truncate; apical angles obtuse, not rounded; basal obtuse and distinctly 

 rounded; disk feebly convex, distinctly impressed, finely and sparsely 

 punctate, the punctures separated by from three to four times their 

 widths, and, near the sides, about twice as large and separated by but 

 slightly more than their own dimensions, the surface not becoming 

 less polished. Elytra quadrate, very slightly wider and one-half longer 

 than the prothorax, feebly impressed near the suture, rather coarsely 

 and deeply punctate; punctures separated by more than once and less 

 than twice their own diameters, slightly sparser laterally. Abdomen 

 parallel, distinctly narrower than the elytra; sides nearly straight;^ 

 border moderate; surface minutely reticulate, also minutely and some- 

 what densely punctate. Legs slender. Length 2.6 mm.

Very easily distinguished from mancus, in which the eyes are 

 also very large, by its much sparser pronotal punctuation and 

 many other characters. 



This species has also been identified as memnonius Er. by M. 

 Fauvel. 



21 T. imbellis n. sp. — Rather slender, black; legs red-brown; an- 

 tennae fuscous, slightly paler at base; pubescence moderate in length,, 

 rather coarse and dense; integuments shining. Head three-fourths as 

 wide as the prothorax, very feebly convex, rather finely, densely punc- 

 tate; prominences moderate; antennae longer than the head and pro- 

 thorax, slender, feebly incrassate; joints two to four uniformly and 

 slowly decreasing in length, the latter elongate, more than twice as 

 long as wide, tenth joint distinctly longer than wide; eyes large, promi- 

 nent, very coarsely faceted; tempora short, strongly rounded, but 

 slightly prominent, not quite one-third as long as the eye. Prothorax 

 two-fifths wider than long, widest just behind anterior third, where the 

 sides are evenly rounded, and thence coarctate to the apex, strongly 

 convergent and straight to the base; the latter broadly arcuate, fully 

 two-thirds as wide as the disk, much narrower than the apex; the latter 

 truncate; apical angles broadly obtuse; basal slightly rounded ; disk 

 rather finely punctate in the middle, where the punctures are separated
