CHAMBERS ON TINEINA OF COLORADO. 127 



margin, and one along the binder portion of the eell, which contains two 

 small dark spots, one of which is at the end of the cell; both of these 

 spots, however, are sometimes wanting. Hind wings pale grayish, with 

 stramineous cilia. Antenna' whitish, annulate with brown. Head and 

 thorax of tbe general hue of the wings or more ocherous ; outer surface 

 of the second joint of palpi densely dusted with brownish, and two 

 brownish anuuli on the third joint. Expanse of wings, (U lines. Edger- 

 ton, June. 



G. bicostomaculella n. sp. — Palpi slender and simple; antenna 1 robust, 

 with the joints very distinct; hind wings scarcely emarginate beneath 

 the apex. Second joint of palpi pale yellow, marked externally with 

 fuscous ; third joint fuscous, with the tip and an annulus about the middle 

 yellow ; antenna* fuscous, annulate with yellow ; face yellow ; vertex and 

 thorax brown. Fore wings pale creamy-yellow, with a silky luster, very 

 sparsely (microscopically) dusted with fuscous, with the base, a small tri- 

 angular costal spot before the middle, and a largo one behind the mid- 

 dle brown, and a line of brown scales around the apex. Hind wings 

 paler than the forewiugs; abdomen and legs pale yellowish, the tarsi 

 annulate with brown, and the tibia stained with fuscous on the outer sur- 

 face. Expanse of wings, 7 lines. Edgerton, in July. 



G. triocellella u. sp. — Second joint of palpi with a spreading brush ; 

 third joint about as long as second; posterior wings incised beneath the 

 tip. Brownish-gray; second joint of palpi white on inner and upper 

 surfaces; third joint with a large white spot ou top about the middle 

 and a minute one close to the apex ; antenna? annulate with whitish. On 

 the fore wing are three ocellated spots, one on the disk, one at the end of 

 the disk, and one on the fold ; they are ocherous, with a brown pupil ; a 

 small ocherous basal streak near to the costal margin ; hind wings pale 

 grayish, with a slight fuscous tinge; legs aud under surface of the body 

 whitish, densely dusted with gray-brown. Expanse of wings, J inch 

 The ocellated spots on the fore wings are indistinct to the naked 

 It is the most common " micro " about Edgerton in June. 



G. concinnisella Cham. — Formerly described from Texas (Cin. Quar. 

 Jour., vol. ii, p. 253). By some mistake the alar expanse is there stated to 

 be 3-lGth inch ; it should be 9-10th. It may prove to be identical with 

 (,'. cupicistrigella Cham, from Kentucky, but I think not. Apicistrigella 

 is silvery white, suffused with pale yellowish, while this species has the 

 fore wings suffused with fuscous, especially the apical half, but it is white 

 at the apex, while apicistrigella has the apex suffused with reddish 

 ocherous. In apicistrigelfti there are three short white costal streaks 

 following the long oblique one; in this specimen there are only two, 

 which are scarcely visible (owing to denudation ? ) in the Texas speci- 

 mens. The "apical spot, or dash", is just within the dorsal margin, not 

 strictly at the apex, and margins posteriorly the white of the apex. Ed- 

 gerton, June.
