CHAMBERS ON TINEINA OF COLORADO. 125 



G. wquipulcella Cham. (Cau.Ent., vol.iv, p. 192). — Two specimeus taken 

 at Edgertou 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 confounded by me. 



G. roseosufasella Clem. (Proc. Acad. ISTat. Sci. Phila., 1860). — Rare in 

 Colorado. Two specimeus taken at Edgerton in July. As widely dis- 

 tributed as the precediug. 



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

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

 rate with pale gray, with several small fuscous specks on the fore wings, 

 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 browm, annulate 

 with whitish ; hind wings pale fuliginous. Expanse of wings, 6 J lines. 

 Monument Park, June. 



G. trilineella n. sp. — Second joint of the palpi with a divided bru§h, the 

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

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

 Hind wings excised beneath the tip. G-rayj; 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 

 sujft'used 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 absent. 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 angulated 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 wing ; 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 wh itish 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 veins 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 distinct fascia, nearly straight ; in others, it is 

 angulated, or not distinct, and in some only traces of the opposite cos- 

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

 not distinct from the dusting of the cilia. In all my specimens, however, 

 the black longitudinal lines on the fold and disk are distinct. Hind wings 

 pale fuscous or smoky, with pale stramineou"^ cilia ; abdomen pale 

 yellowish above, pale gray dusted with darker scales beneath ; legs gray 5 

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

 It shows strong affinities with G. depressostrigella Cham, from Texas. •
