<!. .' oeellella a. sp. — Secondjoint of palpi with a tuft, as in the 9 Anarsia, 

 except that it does not project quite so far forward ; something between 

 that of Anarsia and Chelaria^ as figured in lus. Brit., v. 3. Hind wings 

 slightly emarginate beneath the apex; third joint of palpi smooth and 

 pointed, and as long as the second antennae, slender, simple, with close- 

 set joints, not denticulate. Basal half of outer surface of second joint 

 of palpi blackish, apical half whitish, the two colors distinctly marked? 

 and not shading into each other; inner surface pale gray; third joint 

 pale gray, except the outer surface at the tip, which is blackish ; 

 antenna- dark gray; head, thorax, and fore wings pale gray, the course 

 of the veins beyond the cell distinctly marked by dark lines, the discal 

 cell dark gray, with a nearly circular disk, central whitish spot containing 

 ;i dark gray pupil; abdomen pale gray above, whitish beneath, with a 

 dark line along each side ; on the upper surface of each of the first three 

 segments are two ocherous yellow spots separated by a dark gray line ; 

 legs brownish. Expanse of wings, 9 lines. A single 9 taken at 

 Edgerton in duly. 



G. .' anarsiella n. sp. — This species, which is quite common about 

 Edgerton iu June and July, has very much the appearance of an Anarsia, 

 though the brush of the second joint of the palpi scarcely projects 

 enough in front, being almost exactly as iu G. oeellella (supra). Eight 

 specimens before me are all 9 . I have not seen the male. The antenna' 

 are slender and not denticulated. The neuration of the hind wings is 

 t he same with Mr. Stainton's figure (Ins. i bit., v. iii) of that of G. rufescens, 

 except that iu this species the cell is closed ; that of the fore wings is 

 identical with N~othris verbascella. A worn specimen of this species (!) 

 was also taken at Twin Lakes, altitude 10,000 feet. 



The hind wings are sharply emarginate beneath the tip. Dark steel- 

 gray except a whitish spot on the second joint of the palpi ; white 

 annulations on the tarsi and two or three microscopic whitish specks or 

 white scales scattered over the wings, and the cilia are pale-gray, dusted 

 with dark gray or blackish scales. Hind wings of a bluish smoky hue, 

 with paler cilia. Expanse of wings, 1\ lines. 



G. oehreostrigelld n. sp. — Palpi robust, not very long, with the scales of 

 the second joint divided beneath, but scarcely forming a brush; third 

 joint with the tip suddenly sharpened ; hind wings emarginate beneath 

 the tip. 



Several attempts to describe this species without looking at the pre- 

 vious trials have each given a different account of the wings. Under 

 a strong lens, the color appears to be hoary, almost white, but so densely 

 dusted with brownish as to obscure the ground-color, and streaked with 

 ocherous; under a lower power, it appears pale grayish, tinged with 

 ocherous, and with the ocherous streaks still distinct, and with some 

 short blackish streaks; while to the naked eye it appears very pale gray, 

 tinged with ocherous. Under the lens, the two most distinct ocherous 

 streaks are one along the fold and one from the base within the costal
