CHAMBERS ON TINEINA OF COLORADO. 125 



G. cequipulvella Cham. (Cau. Eat, vol.iv, p. 192). — Two speciineus taken 

 at Edgerton in Jane. A widely-distributed species, having been hereto- 

 fore described from. Kentucky, Texas, and California. It is possible, 

 however, that two closely-related species have been co nfounded by me. 



G. roseosuffmella Clem. (Proc. Acad. ISTat. Sci. Phila., 1SG0). — Rare in 

 Colorado. Two speciuieus takeu at Edgerton iu July. As widely dis- 

 tributed as the preceding. 



G. monumentella n. sp.— Second joint of palpi with the scales thick- 

 ened beueath, hind wiugs excised beneath the tip. Pale ocherous, irro- 

 rate with pale gray, with several small fuscous specks ou the fore wiugs, 

 two of which are on the fold, and a series of indistinct ones around the 

 base of the cilia ; fourth, fifth, sixth, and seventh segments of the abdo- 

 men fuscous on top, and segment pale straw-color ; tarsi brown, annulate 

 with whitish ; hind wiugs pale fuliginous. Expanse of wiugs, GJ lines. 

 Monument Park, Juue. 



G. trilineella n. sp. — Second joiut of the palpi with a divided brush, the 

 scales of the brush longest at the base and gradually shortening to the 

 apex ; third joiut rather slender, pointed, and about as long as the second. 

 Hind wings excised beneath the tip. Gray|; face and inner surface of palpi 

 pale or whitish-gray; thorax gray, with a narrow line along its middle, 

 and one at the patagia darker gray. Upper surface of the fore wings 

 suffused with whitish-gray, with three short black streaks, one of which 

 is about the middle of the fold, another (sometimes this one is inter- 

 rupted) about the middle of the disk, and one at the end of it; sometimes 

 this latter one s abseut. At about the apical third of the wing-length 

 is a dark spot or streak of irregular form and not very definitely outlined, 

 and behind it an augulated fascia, formed by the usual opposite costal and 

 dorsal spots touching or nearly touching each other, is indicated by a 

 paler or whitish-gray portion of the wiug ; it is much more distinct in 

 some specimens than in others ; behind it, nearly to the apex, the wing 

 is darker than before it, but becomes whitish again around the apex, 

 with an indistinct dark spot at the apex. Cilia gray, with a dark hinder 

 marginal line at their base, and dusted with dark scales. In some spec- 

 imens, the courses of the veius beyond the cell in the dark apical por- 

 tion are indistinctly marked by still darker lines. Scarcely any two 

 specimens are alike in the marks on the wings, some being much darker 

 than others ; some have a distiuct fascia, nearly straight ; in others, it is 

 angulated, or not distinct, and iu some ouly traces of the opposite cos- 

 tal and dorsal spots are visible, and in some the hinder marginal line is 

 not distiuct from the dusting of the cilia. Iu all my specimens, however, 

 the black longitudinal lines on the fold aud disk are distiuct. Hind wings 

 pale fuscous or smoky, with pale stramineous cilia ; abdomen pale 

 yellowish above, pale gray dusted with darker scales beneath ; legs gray j 

 tarsi annulate with white. Expanse of wings, 8 lines. Edgerton, in July. 

 It shows stroug affinities with G. depressostrigella Cham, from Texas.
