throughout. Elytra one-half longei- than wide, quite distinctly wider than the 

 prothorax, parallel, broadly rounded at apex ; humeri moderately tumid ; punc- 

 tures rather coarse but only moderately deep, feebly rugose by oblicjue reflec- 

 tion, sparse. Abdomen finely, somewhat densely pubescent, the legs moderately 

 long and slender. Length 2.6 mm. ; ■width 1.1 mm. 



Texas (El Paso). Mr. Dunn. 



The male, if I liaA-e correctly identified this sex by the simple 

 but transversely truncate fifth ventral, appears to diflfer greatly 

 from the usual types of the genus in haAing both spurs of the 

 anterior and middle tibiae simple and slender. The left antenna 

 of the type specimen is deformed, the third joint being very 

 elongate, enveloping the fourth externall}' and extending to the 

 base of the fifth. The four specimens before me are quite uni- 

 form in size, but some are slightly pale and piceous-brown from 

 immaturity. 



20. T. uiodef^tllS n. sp. — Stout, oblong, convex, piceous-black, the elytra 

 pale and castaneous, polished; legs and antenna; pale rufo-ferruginous, the 

 latter slightly obscure at the extreme tip: pubescence rather long but sparse, 

 pale cinereous, even and distinct, closely decumbent. Head slightly more than 

 three-fifths as Avide as the prothorax, polished and smooth Ijut somewhat dull 

 and subscabrous anteriorly, where the two impressions are strongly marked; 

 labrum piceous, broadly rounded; eyes moderate in size; antennae but slightly 

 longer than the prothorax, incrassate toward apex, the tenth joint strongly 

 transverse. Prothorax short, three-fourths wider than long, the sides evenly and 

 strongly convergent, and almost evenly and rather feebly arcuate from base to 

 apex; all the angles obtuse and rounded ; a^jex truncate, much narrower than 

 the base, the latter broadly arcuate; disk smooth, feebly reticulate near the 

 sides, the punctures moderate and remote, becoming coarse and closer toward 

 the sides. Elytra short, oblong, two-fifths longer than wide, slightly wider 

 than the prothorax, very obtusely rounded at apex, the humeri slightly tumid; 

 punctures moderately large, sparse. Abdomen finely and rather sparsely 

 punctate, the legs decidedly slender. Length 2.5 mm. ; width 1.15 mm. 



Kansas. 



The single male serving as the type represents a species allied 

 in man}- structural generalities to simulans, but ditfering in its 

 shorter form, in its rather feebler elytral and coarser pronotal 

 punctures, and in the verj- much shorter fringe of pale hairs along 

 the side margins of the body. The fifth ventral is simple and 

 truncate. 



21. T. separatus n. sp. — Subcylindrical and moderately convex, some- 

 what shining, brownish-black aljove, deep l)lack beneath; legs pale rufo-fer-
