Lepidoptera of New York and Neighboring States 227 



the fascia much broader at inner margin than at costa ; outer spots more obliquely 

 placed than in the grape species. 7% mm. 



Larva with dorsal spots rather fine, and a couple of ventral ones forming a 

 dark line; mining on Nyssa multiflora; case oval. 



The moth emerges in May and can be certainly identified only by breeding. 



Pennsylvania; New York; Xew Jersey; District of Columbia. New York: 

 Mohonk Lake (larvae); Glens Falls and Xew York City (Lintner). 



There is also a species on sweet fern, which has not been distinguished from 

 A. Isabella. 



HELIOZELA Herrich-Schaeffer 



Fore wing (fig. 135) with only three veins running to costa; hind wing with 

 only one medial. Our species has not been examined structurally, and may be 

 an Antispila, but the markings are rather as in Heliozela. 



1. H. eesella Chambers. Deep purple-brown, with two fasciae, starting from 

 inner margin near base and at middle of wing, tapering above, and only reaching 

 halfway to costa; the basal fascia broader and blunter. 6 mm. 



Larva in a flattened gall on leaves of grape; the gall lying on both sides of a 

 vein, and almost completely eaten out before the maturity of the larva. Pupal 

 case cut from the epidermis of the gall, at first oval, but made over into a spindle 

 shape. Larva mature the middle of June; moth emerging about the first of the 

 following May. 



District of Columbia to Ohio. 



COPTODISCA Walsingham 

 (Aspidisca Clemens, not Ehrlich) 



Head and body characters like Antispila ; eyes very small and not visible from 

 above. Fore wing (fig. 133) without cell, the R-stem giving off Rj from its 

 anterior side near base, and two veins to inner margin near apex; the main stem 

 terminating in costa near apex (probably R 4+5 ). Rest of M and Cu obsolete; A 

 simple. Hind wing narrower, linear-lanceolate, Sc simple, short; R-stem simple, 

 in middle of wing, forking over apex, with a branch from lower side at middle; 

 Cu long, simple. 



Larva and pupa essentially like Antispila. Mine relatively smaller, often 

 almost entirely filled with frass, except the part cut out to form the case, which 

 is kept clean. 



The various nominal species are described from specimens bred from different 

 food plants, but the imagoes are nearly indistinguishable; very possibly several are 

 merely slight food-varieties of a single species. 



1. C. splendoriferella Clemens. Head bronzy; antennae fuscous, tinged with 

 golden; basal half, or rather more, of fore wings lead-gray, slightly metallic; 

 from middle to tip golden, with a broad, nearly straight, triangular, silvery streak 

 running from costa three-fourths way (near tip of broad part of wing) to 

 center of wing, dark-margined on both sides; nearly joined by a dorsal streak 

 opposite it, with converging dark margins, behind which is a dark brown blotch. 

 In costo-apical fringe a silver streak edged on both sides with black. A black 

 apical spot with bluish-silver center. Dorsal fringe brown with a black basal line 

 interrupted by the silvery streak. Hind wing leaden gray, fringe yellowish brown. 

 4—4% mm. (Aspidisca Clemens; pruniella Clemens; Lyonetia saccatell-a Packard). 



Mine at first linear, then a small transparent blotch, the cocoon using almost 

 all of the clean part; on Crataegus, wild cherry, and apple. 



The species is general. Xew York, Ithaca, East Greenbush, Albany, Fishkill.
