358 A Preliminary Monograph of the 



34 T, protons n. sp. — Rather slender, feebly convex, black; legs dark 

 piceous-brown, antennae dark-brown, slightly testaceous at base and 

 apex; pubescence fine, short, moderately dense, except on the abdomen, 

 where it is very sparse; the latter strongly shining, elsewhere slightly less 

 so. Head slightly narrower than the prothorax, feebly convex, minutely 

 and rather sparsely punctate; prominences short, broad, moderate; eyes 

 small, slightly convex, not very prominent; tempora a little longer than 

 the eye and slightly more prominent, broadly rounded; antennae mode- 

 rately robust, distinctly longer than the head and prothorax, feebly 

 clavate; second joint distinctly longer and more robust than the third, 

 scarcely twice as long as wide, fonrth nearly as wide as long, tenth 

 distinctly wider than long. Prothorax a little less than one-half wider 

 than long, widest at anterior two-fifths, where the sides are rather 

 broadly, evenly rounded, coarctate to the apex, moderately convergent 

 and becoming nearly straight toward base; the latter feebly arcuate, 

 nearly three-fourths as wide as the disk, and slightly narrower than 

 the apex; apical angles obtuse and slightly rounded; disk almost im- 

 perceptibly bi-impressed, very finely and moderately densely punctate. 

 Elytra distinctly wider than long, distinctly wider and nearly one-third 

 longer than the prothorax, very feebly impressed near the suture, 

 rather coarsely and deeply punctate, the punctures separated by more 

 than their own diameters. Abdomen fully as wide as the elytra; sides 

 parallel and somewhat strongly arcuate; border rather strong; surface 

 almost smooth and polished, very minutely, sparsely punctate. Legs 

 short and slightly robust. Length 2.3 mm. 



North Carolina (French Broad River 1). 

 Peculiar in its rather short elytra, more highly polished ab- 

 domen, and coarse elytral punctuation. 



35 T. naiiulus n. sp. — Rather slender, moderately convex, black; 

 legs piceous, tibiae, tarsi, and antennae brovvn; pubescence short, 

 dense, excessively fine and scarcely visible on the head and pronotum, 

 coarser, longer, sparser, and more distinct on the elytra and abdomen; 

 integuments subalutaceous. Head very slightly narrower but not longer 

 than the prothorax, strongly convex, extremely minutely and densely 

 punctate; prominences small, moderate; eyes very small, very feebly 

 convex, not prominent; tempora broadly rounded, slightly longer and 

 distinctly more prominent than the eye; antennae rather robust, as long 

 as the head and prothorax; club distinct; outer joints strongly trans- 

 verse; second as long as the next two together and distinctly more 

 robust, fourth wider than long. Prothorax one-third wider than long, 

 widest slightly before the middle; sides very broadly rounded, coarctate 

 to the apex, more strongly convergent and broadly arcuate to the base; 

 the latter feebly arcuate, nearly three-fourths as wide as the disk, slightly^
