deserting it, leaving a network of brown veins. Finally the larva forms the usual 

 cone. 



Southern Ohio; Kentucky. 



Supposed summer form: Antennae ochreous, broadly annulate with dark; darker 

 toward the apex; palpi yellowish white; third segment annulate with dark just 

 before the apex; maxillary palpi yellowish white. Face, head, and thorax pale 

 golden; vertex bronzy; fore wing suffused with purplish bronze; a pale golden 

 patch at base; triangle pale golden, large, truncated on fold, extended out on 

 costa, with very slight, dark points on the costal edge. Hind wing fuscous with 

 reddish fringe. Hind tibiae and tarsi mostly yellowish white. 10 mm. 



The larva lives in a mine on the under side of Carpinus and Ostrya, the blotch 

 when finished becoming similar to that of the autumn form, as the parenchyma 

 is eaten out. 



24. G. superbifrontella Clemens. Rose-violet, iridescent on a base of tawny 

 yellow; palpi yellow with brownish tip; antennae dull yellow, vertex shaded with 

 reddish violet; thorax wholly golden. Hind wing very dark. Fore wing with 

 large, irregular, costal patch, and base of inner margin suffused with golden. 

 11 mm. (alchimiella of authors). 



June to August. Larva in a conical roll on Hamamelis; pale green with pale 

 brown cervical shield. 



Distribution general. New York: Crosby (Yates County) ; Ithaca. 



G. alchimiella Scopoli, a European oak species, has been reported from Essex 

 County, New Jersey. The golden spot on the inner margin is more sharply 

 defined; the head is lighter crimson rose; and the tegulfe and a spot on the disc 

 of the thorax are tawny. Packardella has sometimes been determined as this 

 species. 



25. G. blandella Clemens. Dark purple; face yellowish; vertex with purple- 

 tipped scales; antennae strongly annulate; palpi yellowish with a brown spot on 

 outer side of second joint, and on tip of third. Fore wing with usual patch very 

 large and irregular; the wing strongly golden-iridescent at base, sometimes form- 

 ing a central, diffuse, basal spot. Fringe dark with a pale line in the middle; 

 hind wings pale fuscous. 



This species is unknown to me. 

 Virginia. 



26. G. juglandivorella Chambers. Closely similar to G. blandella; joints of 

 maxillary palpi purple-tipped; vertex largely purple; thorax with three lemon- 

 yellow stripes; yellow patch perhaps less extensive. 8 mm. 



Larva on black walnut; at first in a linear mine, reaching an inch long, then 

 under a series of small flaps, eating the parenchyma, and pupating under the last 

 flap. The larva changes to the cylindrical form on leaving the mine. 



I have not seen this form. The preceding species and this probably identical; 

 and are so considered by Ely. 



Virginia. 



27. G. glutinella Ely. Summer form. Reddish bronze, face yellow; palpi straw 

 color, shaded with dark brown just before the apex, darker outwardly; antennae 

 annulate. Fore and middle femora and tibiae reddish bronze; hind tibiae dark- 

 shaded at apex. Fore wing with some straw-yellow scales, especially toward 

 apex of costa; triangle shining golden, truncated shortly on fold; no outer spot. 

 Fringe gray, with two dark lines around the apex. 12-13 mm. 



July-August. Larva in a roll on Alnus glutinosa, in July. 



Southern Connecticut. 



Supposed icinter form: Ground dark purplish, intermixed with straw-colored 

 scales; face pale yellowish, edged with brown on sides; vertex darker and more 

 straw colored; palpi shaded throughout with dark purple, third segment with a 

 heavy black ring at the tip; maxillary palpi also shaded with purple. Antennae
