Lepidoptera of New York and Neighboring States 157 



than second, its outer part longitudinal A line of black subterminal scales and 

 a black line in fringe. 12 mm. (mugnella in part of collections.) 



Larva in a spindle-shaped gall on Helianihus tra&Keliiformis, located in the 

 upper part of the stem; about 2 cm. long and 5 mm. wide. Cocoon grayish 

 brown, smooth, and strongly flattened. Larva in September; moth from end of 

 May to early July. 



Cincinnati, Ohio. 



4. B. montana Braun. Similar to B. mugnella and B. fusicola. Vertex with 

 some fuscous scales; shaft of antenna all gray. Fore wing with three oblique 

 streaks from the costa, parallel and equidistant, besides the dark apical shading; 

 the first two streaks confluent below. 11 mm. 



June. 



Mountain Lake, Virginia. 



5. B. niveella Chambers. White; slightly yellowish at tip of wing and vertex; 

 fore wing with some black scales in costal fringe, and two lines in dorsal fringe 

 only. 



Magnella is probably a fully marked variety of this; in fact I have seen inter- 

 mediate specimens, bred from Solidago. 



Kentucky. New York: Rock City (Cattaraugus County). 



6. B. errans Braun. Head and thorax white, brown in center; shaft of antennse 

 brown. Fore wing dark brown, with longitudinal white streaks at base above and 

 below middle, leaving a brown longitudinal streak between them; two oblique 

 white streaks on costa, the more basal heavier, and a white costo-apical spot in 

 fringe; a streak, followed by two white dots, on dorsum. A dark line in fringe. 

 Sometimes with the white streaks so enlarged as to dominate over the brown 

 ground, and more or less fused. 10 mm. 



Food Aster shortii. Larva forming a contorted linear mine in the fall, end- 

 ing in an enlargement in which is spun a silken wintering cocoon. Larva in the 

 spring boring in the tip of a growing shoot, killing it. Pupal cocoon whitish, 

 with faint longitudinal ridges. Moth in May. 



Cincinnati, Ohio; Okefinoke Swamp, Georgia. 



7. B. species C. Head dirty white; eye-caps white; antennse annulate, light 

 dull brown and dirty white; fore wing whitish and dull light brown, with a 

 quadrate, blackish patch in middle of fold; a short oblique brown shade before 

 middle, extending narrowly along costa to base; another from three-fifths way out 

 on costa, to outer margin above apex, ending in a black dot; and a subtriangular, 

 costal subterminal patch; the bands broader than the distance between them; a 

 contrasting, black, apical hook; tuft black, followed by a small brown area. 

 6-8 mm. (ambrosicefoliella auct., apparently not of Chambers). 



Doubtfully distinct from the next two species. Larva on Ambrosia; cocoon 

 ribbed. 



Kentucky; western Pennsylvania; Missouri; and elsewhere. 



8. B. agnella Clemens. Bands powdery black on light brown, not strongly con- 

 trasting; anal dot reduced to a few scales. Head mostly white. 6 mm. 



Kentucky; District of Columbia. 



9. B. copeuta Meyrick belongs to this group. It was described from Ontario. 



10. B. capitealbella Chambers. Antennae annulate with yellow-brown; ground 

 color pure white and markings brighter yellow-brown; no black scales at anal 

 angle; first fascia not continued along costa to base. Otherwise like B. agnella. 



I have seen the type. 



11. B. albicapitella Chambers. Cream color, very sparsely dusted with fuscous, 

 no brown; center of tuft and somewhat blurred bands on wing yellow. 5 1 /* mm. 



This is luteella of collections, but not of Chambers. 

 Kentucky. 



12. B. litigiosella Zeller. Pale si raw yellow; the scales of the ground tipped 

 with contrasting dark brown; little or no brown on face; the brown more distinct
