The male, which is the onl^' sex known to me, has the fifth ven- 

 tral short, only slightly- longer than the fourth and broadly sinu- 

 ate toward the middle at apex with the disk unmodified, and the 

 genital segment broadly emarginate and broadl}' impresso-canal- 

 iculate along the middle, the under part of the dorsal p3gidium 

 large and densel}' bristling with short black hairs at apex. 



38. T. iiisequalis n. sp. — Parallel, moderately narrow, convex, polished, 

 black, the elytra finely riigulose, ahitaceous and -with a very feeble seneo- 

 piceoiis tinge; legs and antenna; red, the eleventh joint of the latter dusky; 

 pubescence even in length, ■s\ithout trace of intermixed set», rather coarse 

 and sparse, suberect, dark near the elytral suture; marginal fringe of the pro- 

 notum dense, even and very short, of the elytra longer and cinereous. Head 

 about two-thirds as wide as the prothorax, rather coarsely l)ut not densely 

 punctate, the interspaces smooth; anterior impressions very broad and feeble; 

 epistoma with only a very fine pale apical border: labrum very short and 

 broad, feebly arcuate at apex; eyes rather large and prominent, attaining the 

 base; antenna short, barely longer than the prothorax, rather broad and 

 strongly compressed, the tenth joint strongl}- transverse and wider than the 

 eleventh, fifth very feebly dilated. Prothorax two-thirds wider than long, the 

 sides subparallel, evenly and strongly arcuate; all the angles obtuse and 

 rounded but traceal)le; apex just visibly narrower than the base; punc- 

 tures sparse, not very coarse but widely impressed; interspaces smooth and 

 polished, not in the least rugose at the sides. Elytra barely one-hah longer 

 than wide, not distinctly wider than the prothorax, parallel, obtusely rounded 

 behind, broadly sinuate at base, sparsely and quite coarsely punctate. Ab- 

 domen finely and somewhat densely cinereo-pubescent. Length 2.6-2.8 mm.; 

 width 0.9-1.1 mm. 



Colorado. 



The male serving for the t^^pe has the fifth ventral broadly trun- 

 cate at apex, the adjacent edge feebl}' inflexed and subimpunctate 

 but with the disk otherwise unmodified. Three males. 



39. T. subcalTUS n. sp. — Oblong, convex, highly polished and black 

 throughout; legs black, the tibi;e and tarsi piceo-rufous, the former dusky to- 

 ward base; antennae black, the funicle scarcely visibly picescent toward base; 

 pubescence rather fine, short and sparse, suljdecumbent, cinereous, the hairs 

 blackish on the pronotum except near the sides, and in a broad subsutural 

 stripe on each elytron ; marginal cilia of the pronotum even, dense, somewhat 

 long and in great part blackish in color, of the elytra longer, sparser and more 

 cinereous. Head three-fifths as wide as the prothorax, finely, sparsely punc- 

 tate, the interspaces smooth, rugulose toward the sides, the impressions very 

 large, broadly impressed; epistoma rather long but wide, truncate, black; la- 

 brum ])road, circularly rounded, slightly pale near the ape.x ; eyes rather large
