this is rather closel}'^ punctured and pubescent. The epistoma is 

 short, the suture distinct and broadly angulate, the basal three- 

 fifths corneous and sculptured like the adjoining front, the apical 

 two-fifths abruptl}' thin, transparent and devoid of sculpture. 



5. T. salicola Lee— Trans. Am. Eiit. Soc, V, (1875), p. 174. 

 Nearly similar to the last in general form and coloration, but 



with larger and more convex eyes and straight parallel tempora 

 behind them, the cl^'peus longer, less sculptured, divided by a 

 feebler and more arcuate suture, the apex of the thin portion 

 narrowly grooved. Prothorax distinctl}^ larger when compared 

 with the head and more broadly rounded at the sides anteriorl3\ 

 Elytra covering virtually the entire abdomen in the male, parallel, 

 rather flat, one-half longer than wide, three-fourths wider than the 

 prothorax, alutaceous, the pubescence somewhat sparse. Under 

 surface of the hind body intense black thi'oughout, the legs pale 

 testaceous. Length 3.0 mm.; width 0.9. 



Utah, — Cab. LeConte. The male has the fifth ventral not quite 

 as long as the fourth, broadly truncate at apex, the truncature 

 broadly and feeby siuuate in the middle. The under surface of 

 the hind body in tricolor is ver}^ pale throughout, the abdomen 

 being rather more closely punctate than in salicola^ and, as usual 

 in this section, there are two longitudinal series of long tactile 

 setse, two setae to each segment. The duskj' tip of the el3-tra, re- 

 ferred to in the original description, is due to the black apex of 

 the abdomen by diaphaneity; in the following species, however, 

 the tip is reall}" black. 



6. T. deiisus n. sp. — Narrow, subdepressed, opaque throughout above, 

 the abdomen shining, dark rufous, the under surface of the hind body deep 

 black; pygidium black; elytra with a black band just behind the middle 

 which is expanded posteriorly at the side margins, joining a narrow black 

 apical band; pubescence very short, decumbent, even, moderately dense and 

 not very conspicuous. Head subquadrate, not quite as long as wide, truncate 

 and medially subcanaliculate at base, the angles rounded; tempora long, be- 

 coming straight and parallel for some distance behind the eyes, the latter 

 moderately small, convex, more prominent than the tempora; disk finely, 

 granularly punctate; antennae rather thick, very feebly incrassate, fully one- 

 half longer than the head, the eleventh joint as long as the two preceding com- 

 bined, deeply constricted behind the middle, the basal lobe as usual thicker. 

 Prothorax somewhat small, much narrower than the head, noticeably wider 

 than long, widest and rather strongly rounded between apical third and fourth, 

 the sides thence obli((ue and straight, becoming parallel only just before tJie
