Lepidoptera of New York and Neighboring States 397 



4. MELISSOPUS Riley 



Metallic scaling more extensive than in Carpocapsa pomonella. Hind tibia of 

 male with very long hair below and above toward its tip, and metatarsus with 

 heavy hair above; hind wing (fig. 252) roughly and thickly scaled on inner 

 margin and at base of Cu and 2d A, but without hair pencils. Otherwise like 

 Carpocapsa and Laspeyresia. 



1. M. latiferreanus Walsingham. Light red-brown, with a heavy erect median 

 lead-colored fascia; a slightly narrower one three-fourths way out; and a slender 

 and broken submarginal one, strongly curved below costa. Between the two outer 

 fascise there are some broken black bars and streaks. Fringe lead-colored, with 

 a reddish line in the base; hind wing mouse gray. 15 mm. 



Two broods in Missouri, the second perhaps partial; July and August; late 

 September. Larva on young acorns; cocoon formed between a leaf and a nearly 

 circular piece cut out of another. 



Our eastern form, as described above, is var. orichalceana Walsingham. Typi- 

 cally the second fascia is rudimentary (California). 



Generally distributed north to Montreal. New York: Ithaca, Karner. 



5. GYMNANDROSOMA Dyar 



Similar to Ecdytolopha; palpi with third segment porrect, slightly more beak- 

 like. Wings (fig. 251) more than half as wide as long, and rough-scaled; thorax 

 tufted behind. M 2 of hind wing more curved than in Ecdytolopha. Abdomen of 

 male with a naked patch above, flanked by a couple of pale hair-pencils; hind 

 tibia with a fanlike tuft of hair, with metallic scales at its base. Hind* wing with 

 heavy tufts of hair and enlarged spatulate scales on inner margin; the fringe 

 on Cu extremely heavy, but not modified. 



1. G. punctidiscanum Dyar. Irregularly mottled and strigose with fuscous, 

 blackish, and some lead gray, the outer part often largely dirty white and con- 

 trasting. Discal dot small, white, sharply defined in a black shade. No definite 

 line in fringe. Hind wing mouse gray. 18-25 mm. 



The moth has been taken from May to July. 



New Jersey and northern Illinois to South Carolina. New York: Ithaca, New 

 York City; Maspeth, Long Island. 



6. ECDYTOLOPHA Zeller 



Palpi rough-scaled; upturned to middle of front; with short third joint (fig. 277). 

 Thorax tufted behind; wing rough with transverse ridges of slightly enlarged raised 

 scales, two and one-half times as long as wide; with rounded outer margin and no 

 distinct notch; all veins separate and normal. Hind wing (fig. 250) with R and 

 Mj approximate, M 2 widely separate, and parallel to M 3 , nearly straight; M 3 and 

 Clli connate; the male with a thickened patch above 3d A at base, but not other- 

 wise modified. Tibiae with the usual hair only. 



This genus seems intermediate between Laspeyresia and Olethreutes, and together 

 with Gymnandrosoma, has been sunk to the latter by Walsingham and Durrant. 



1. E. insiticiana Zeller. Basal half fuscous, mottled with dull black; outer half 

 dirty white, striate and mottled with fuscous and some black; the boundary some- 

 what oblique and nearer base on inner margin; sharply defined below, diffuse 

 above; the outer markings usually forming a small triangular largely black anal 

 spot. Hind wing mouse-gray. 25 mm. (H 48:29.) 



May to August. The larva may be found in August, in twigs of locust, making 

 a fusiform gall which is sometimes very slightly swollen when in stout twigs. 

 The passage to the exterior is kept open and the frass thrown outside. The larva
