mines, whose entrance is guarded with a broad tube of silk. Larva in May; 

 moth in early June. 

 Cincinnati, Ohio. 



3. S. fuscicomella Clemens. Black-brown, slightly iridescent, with a slight 

 yellowish iridescence except on fringe. 



This is probably the same species as the next. It was taken in -Tune. Larva; 

 with 8. eboracensis. 

 Pennsylvania. 



4. S. eboracensis Zeller. Wholly blackish. Base of palpi whitish on outer side. 

 9-12 mm. 



June and July; end of August and September. Larva' in webs in tops of thistle. 

 Maine to Texas. New York: Rock City (Cattaraugus County), Portage, 

 Crugers, Sea Cliff, Long Island. 



5. S. basilaris Zeller. R, and R 3 wholly united, running to apex. Purplish 

 fuscous. Face ochreous at the sides in variety flavifrontella Clemens. Fore wing 

 with a few golden bronze scales, forming a spot at the apex of the membrane, and 

 often a streak in the base of the fold. 12 mm. 



In variety flavifrontella the apical spot is also enlarged. 



Distribution general in June and July. New York: Keene Valley; Cold Spring 

 Harbor, Long Island. 



6. A. pilosella Zeller. Brown. Palpi yellow-brown: inner third of fore wing 

 with scattered, slender, yellow hairs. No iridescence. 10 mm. 



This species is unknown to me. 

 Massachusetts. 



7. S. aferrimella Walker, a plain blackish species from west of Hudson Bay, is 

 unknown to me; it is possibly the same as 8. eboracensis, but the mala genitalia 

 would have to be studied to make sure. 



S. charon Meyrick, described from North Carolina, has a pale streak in the fold.

(ChoreutidcK ; Hemerophilidce; Yponomeutidce, in part) 



Head smoothly scaled; ocelli in our species large and conspicuous; 

 tongue scaled at base ; maxillary palpi minute ; labial palpi upturned to 

 middle of front or beyond, sometimes beyond vertex; normally smooth 

 scaled, but often with long loose hair on second joint or rough hair on 

 second and third joints. Antennae without pecten ; with the outer row 

 of scales of each segment usually complete, but narrow, and the inner 

 row broadly interrupted below and replaced by conspicuous sense-hairs 

 (minute in the Florida genus Tortyra). Middle and hind tibiae with 

 more or less hair above, which tends to be stiff and to gather opposite 

 the spurs; or else smooth scaled. Wings exceptionally broad; macro- 

 like in shape ; sometimes with the fringes not wider than in some macros, 

 and but little lengthened at the anal angle ; only in Glyphipteryx, lance- 

 olate with broad fringes, and even in this genus w T ith rounded apex. 

 Fore wing with a large accessory cell, and often with base of M more 

 or. less preserved ; cell normally almost squarely cut off at end ; R 4 

 and R 5 stalked only in Allononyma, R 5 running to apex, or, usually, 

 to outer margin ; Cu, arising close to angle of cell ; 1st A rather weak, 

 free; 2d A with a large basal fork. Hind wing usually somewhat
