The caterpillar when young forms the mine usual in the genus; then lives in 

 a cylindrical nest made by rolling clown one side of a leaf. The cocoon is spun 

 in the roll. The moth has been obtained in April and in August. 



Connecticut to Missouri. New York : Ithaca. 



13. G. bimaculatella Ely. Light brown with crimson iridescence, the antennge 

 yellow -brown. Head and thorax dark brown, darker than the wings; the face 

 silvery. Palpi with a little black at the tip only. Fore wing with first golden 

 spot large, triangular, practically reaching inner margin; and second nearly, or 

 quite, in contact with it, less perfectly triangular; or roughly semicircular, with 

 a few, obscure, dark spots between it and the apex. Apical fringe yellow-gray with 

 darker lines. 11 mm. (burgessiella of collections; amphidelta Meyrick?). 



The caterpillar lives in a cone on red and soft maple. The species seems fairly 

 common but is usually taken for something else. 



Ontario to Connecticut; New York; Missouri. New York: Ithaca. 



14. G. species A. Similar, much smaller; first golden spot narrow, barely reach- 

 ing fold, crescentic, followed by four successively smaller, golden dots on costa, 

 the last practically apical, and each defined on the outer side with a black line, 

 fringe mostly blackish, with the usual darker lines. 7-8 mm. 



Moth in September and October. Larva on maple. 

 New York ; Missouri. 



15. G. vacciniella Ely. Dark purplish, including vertex and upper part of. face; 

 palpi with brown tips; antennae annulate, as usual in the genus; fore wing with 

 two spots, the first triangular, with its basal margin rounded and its outer mar- 

 gin perpendicular, and reaching to fold; outer spot separated from the first by 

 about its width. Base of inner margin yellow. Fringe smoky gray, dark at apex 

 and with obscure lines in it. 11 mm. 



The moth flies at the end of July. The larva feeds on Vaccinium. 

 Pennsylvania. 



G. anthobaphes Meyrick is similar, but with a small additional golden spot at 

 anal angle. It occurs at Lake Muskoka, Ontario, in July and August. 



16. G. belfrageella Chambers. Purple. Face and palpi white; a dark dot on 

 tip of second segment of palpi; costal triangle typically pale golden, truncated 

 on the fold, and extended as a wide band along the costa to the beginning of the 

 fringe; base of inner margin dark. 11 mm. 



Rarely the costal patch is cut into two separate spots. 



The larva feeds on Comus asperifolia, at first in a linear winding tract on the 

 under side of a leaf, then in a blotch, which is crinkled later; finally in the 

 usual cone. It pupates in a fold of the leaf. Other specimens, which roll the 

 whole leaf in a long cylinder, appear to make the same moth, but more often 

 with separate spots. This name is often misapplied to one or another of the maple 

 species. 



Southern Ohio; Texas. 



17. G. coroniella Clemens. Dark yellowish, overlaid with crimson; head dark 

 yellowish; palpi with third segment dark on outer side. Fore wing with a tri- 

 angular patch at middle extending only to fold, and not running out on costa; 

 a couple of dark points on costa within it, and a small pale spot on costa beyond 

 it; apex pale; fringe yellowish, tipped with black. 10 mm. 



Larva on birch. 

 Illinois. 



18. G. packardella Chambers. Light orange with strong crimson iridescence, 

 strongly variable in brilliance; antenme ringed with golden and fuscous as usual 

 in the group; occiput golden, face silver white; fore wing with a nearly equilateral, 

 golden triangle, reaching nearly to the inner margin; and inner margin at base 

 shaded with pale golden. 12 mm. (inomatella Chambers, in part; elegantella 

 Frey. )
