Lepidopteea of New York and Neighboring States 159 



margin; fore wing brown, white at base; — the oblique, brown, antemedial area 

 followed by a white fascia, interrupted at middle of wing and erect below, with 

 the black tuft on its edge; white spots at middle of costa and anal angle; tending 

 to join a streak from costa. Much like augustata, but wholly lacking the silver 

 basal dash. A velvety brown apical spot, followed by a curved line in the fringe. 

 (H. p. 431 f. 250.) 



The larva feeds late in the autumn, in the usual manner on white birch, which 

 it may disfigure badly; but it does little real damage because the leaves are almost 

 ready to fall when it appears. The moth emerges in the spring. 



This species is of general distribution south to Pennsylvania. New York. 



19. B. locuples Meyrick. Blackish brown; head pale bronzy, with darker tuft. 

 Fore wing with triangular golden spots at middle and near apex of costa; a 

 larger transverse spot at middle of inner margin and a smaller spot at tornus. 

 Hind wings dark; fringes gray. 7 mm. (Unknown to me.) 



July- 

 Toronto. 



20. B. ainsliella Murtfeldt. Blackish, heavily dusted on a dirty white base; 

 vertex with fuscous tuft; eye-caps whitish, antennae annulate. Fore wing with 

 ground color very largely blackish; the pale parts outlining an oval, blacker patch 

 on inner margin, parallel to whose upper, outer side there is a pale streak running 

 down from the costa (variabilis Braun). 



The larva normally feeds on black oak, and has the habits and cocoon usual 

 in the genus; in an epidemic it attacks many trees. 



B. ilecella Busck, a similar, holly-feeding species described from Texas, is to 

 be expected in the range of its food plant. 



21. B. crescentella Braun. Head whitish; some dark hair in tuft; fore wing 

 ochreous or darker brown; basal dash white, faint in lighter specimens, extending 

 to middle of wing, with a dark shade below it; a costal streak at middle of wing, 

 oblique and concave outwardly; a less oblique streak three-fourths way out; with 

 a darker space between the two; a white streak over an irregular black spot at 

 apex; dorsal spot dark brown, edged with white. 7-9 mm. 



The larva makes a trumpet mine, with a central frass-line, on aster, Solidago, 

 and Erigeron, a single larva making several mines. But it never lives externally. 

 The cocoon is normal, white. The moth flies in July. 



Ohio to Toronto, Ontario, and New Hampshire. New York : Otto, Florida. 



22. B. cuneigera Meyrick appears to be similar to crescentella but with the 

 disc of thorax white. It was described from Ontario. 



23. B. angustata Frey and Boll, of which crescentella may be a variety, is similar, 

 with a white head and brown thorax, and a dark brown fore wing, with white 

 markings. The thorax is typically white in B. crescentella. 



8. PEILONOME Chambers 



Hardly distinct from Bucculatrix. Face shorter, truncate below, exposing 

 the drooping labial, and minute, folded maxillary palpi. Only one species known. 



1. P. clemensella Chambers. Palpi, face, and eye-caps white, the latter with 

 orange upper edge; antennae reddish orange at base, the rest nearly white; thorax 

 white, with broad pale orange area behind, and with orange spots on shoulders; 

 fore wing reddish orange, with broad white streaks below costa and on inner 

 margin, the latter extending to a small tuft of brown scales, then turning 

 obliquely up and meeting the end of the other streak; an oblique streak from 

 costa, two-thirds way out, extended along costa toward base. Apex dusted with 

 dark brown; a brown hook in apical fringe, and two converging streaks in dorsal 

 fringe. 8 mm. 



Larva on hickory and linden. Moth in July. 



Northern New Jersey to Kentucky. New York (Beutenmuller).
