240 J. L. LECONTE, M. D. 



Head large, broailly rounded behind, broadly concave (a sexual character?) 

 Prothorax wider than long, slightly narrowed behind, truncate in front, 

 broadly rounded at base, sides nearly straight, disc longitudinally impressed. 

 Elytra oue-third longer than the prothorax and not wider. Length 1.4 ;nin ; 

 .05 inch. 



Texas, Belfrage; two specimens. lu one the dorsal impression of 

 the prothorax is strongly marked, in the other it is merely an im- 

 pressed line, distinct at base, but obsolete in front. I do not know if 

 this be a sexual character or an individual deformity. 



2. T. oxytelinilS, n. sp. — Broader, more depressed, without lustre, dull 

 blackish-brown; elytra reddish, antennae and feet yellow-testaceous ; antennae 

 gradually thickened externally, outer joints rounded, scarcely transverse; head 

 not so wide as the prothorax, slightly narrowed and rounded behind the eyes. 

 Prothorax wider than long, strongly rounded on the sides, more broadly at the 

 base, hind angles very obtuse and rounded; disc indistinctly channeled, and 

 broadly impressed near the sides. Elytra twice as long as the prothorax, red- 

 dish-brown, base and margins dusky; sutural angle very much rounded. Length 

 .08 mm; .03 inch. 



One specimen ; Oak Grove, California. 



3. T. flavicornis, n. sp. — Narrower, depressed, without lustre, brown ; 

 abdomen blackish; antennse and legs testaceous, the former with the outer 

 joints larger, rounded, scarcely transverse, slightly darker. Head scarcely 

 narrower than the prothorax, rounded behind. Prothorax not longer than the 

 head, rounded on the sides, nearly truncate before and behind, angles much 

 rounded. Elytra one-third longer than the prothorax. Length .07 mm ; nearly 

 .03 inch. 



Two specimens, salt marsh, Coney Island, near New York. A badly 

 preserved specimen from Lake Superior seems to belong to this species, 

 but its condition does not permit of accurate determination. 



4. T. brachypterus, n. sp. — Narrow, depressed, entirely dull black, 

 opakc, finely puljesceut. Antennae stout, scarcely longer than the head and 

 thorax, outer joints transverse. Head not narrower than the prothorax, sides 

 nearly parallel behind the eyes, base broadly truncate. Prothorax wider than 

 long, rounded at the sides, slightly narrowed behind, angles rounded into the 

 base. Elytra not wider and hardly as long as the prothorax, finely punctulate, 

 sutural angle very slightly rounded. Abdomen densely punctulate. Length 

 .06 mm ; .025 inch. 



Detroit, Michigan, found in abundance by Messrs. Hubbard and 

 Schwarz. This species is anomalous by the very short elytra, and 

 much less rounded sutural angle but does not appear to differ other- 

 wise. 



5. T. finibriatlis, n.sp. — Less elongate, sooty brown, without lustre; head 

 rounded, a little narrower than the prothorax. Antennae entirely piceous, outer 

 joints a little thicker, and slightly transverse. Prothorax twice as wide as long,
