Stenoma leucillana Z. 



Specimens in my collection, taken by Belfrage in Texas, agree very closely with 

 Walker's type of the Nova Scotian algidella, bnt comparing it with a series of what I 

 take to be leucillana Z., it can only be regarded as a dark variety of the female of that 

 species. I think it extremely doubtful whether leucillana Z. is really distinct from the 

 well-known schlaegeri, which varies sufficiently in size and color to connect it with 

 this somewhat smaller and paler form. Indeed if I have rightly determined Zeller's 

 leucillana it would be imposible to draw the line between them in a lengthening series. 

 Until an opportunity may occur for examining the type specimen in the Berlin Mu- 

 seum, I prefer to err on the side of caution rather than to treat the name as a syn- 

 onym. All my specimens of this smaller form have the uncus simple as in the true 

 schla egeri. 



Stenoma algidella Wlk. 



For the present I shall adopt the same course with regard to Cryptolechia algidella 

 Wlk., which is probably also only a small form of schlaegeri, although occurring so far 

 northward as Nova Scotia. Should the acquisition of further material enable me to 

 express a more decided opinion the alteration can be made in the final revision of the 

 index. 



Stenoma furcata sp. n. 



Antenna? in the $ brownish, finely ciliated on both sides; in the 9 the color is much 



paler. 

 Head and palpi white. 

 Thorax slightly tinged with brownish-gray on the upper and central parts, without 



a patch of dark scales behind it. 

 Fore wings elongate, narrow, produced, but somewhat depressed and rounded at the 

 apex ; the costa very slightly arched at the base, scarcely convex beyond it ; api- 

 cal margin oblique ; dorsal margin straight, almost parallel with the costal, but 

 slightly diverging to the anal angle, which is ill-defined ; white, with a slight 

 tinge of brownish-gray, commencing near the base of the dorsal margin and ex- 

 tending to the anal angle below the discal cell, and very faintly in a narrow line 

 along the base of the cilia in the apical margin ; cilia white, tiuged with grayish 

 towards the anal angle and along their tips. In the 9 there is a faint indication 

 of pale, grayish clouds and spots at the end of the cell, and of a pale grayish 

 transverse line between this and the apical margin on the lower half of the wing, 

 and in the abdominal angle are some raised scales, as in schlaegeri (these would 

 probably be found also in better specimens of the $ ) ; there are also a few di- 

 vided black scales in the middle of the cilia ; under side strongly clouded with 

 brownish-gray ; the costal and apical margins narrowly paler. 

 Hind-wings very broad, evenly rounded, but somewhat produced at the apex ; dark 

 cinereous in the $ ; pale grayish-ochreous in the 9 ; cilia whitish ; under side cin- 

 ereous. 

 Abdomen cinereous ; uncus abruptly bent over from the base, distinctly divided into 

 two short forks at the apex ; lateral claspers produced into two angular points, 

 of which the lower one is smaller and sharper than the upper. 

 Legs whitish, unspotted. 

 Exp. al. : $ 27, 9 30 mm . 



Habitat, Arizona. (Two males and two females collected by the late H. K. Morrison. ) 

 Type, $ 9 , Mus. Wlsm. 



This species differs from Stenoma schlaegeri Z. in its narrower and more elongate 

 fore wings, which in the specimens before me have little or no indication of the gray 

 clouds and blotches prevalent in that species, and very noticeably in the form of the 

 uncus; also in the absence of the dark patch of scales at the back of the thorax. I 

 have a single specimen, collected by myself in California in 1871, which might be re- 

 garded as an intermediate link between this species aud Stenoma schlaegeri. It has
