Lepidoptera of New York and Neighboring States 173 



The species is evidently widespread but appears common only northward. New 

 York: Wilmington, Mt. Whiteface, McLean. 



7. G. flavimaculella Ely. Brown; face overlaid, and vertex more or less scaled, 

 with pale yellow-brown; antennas annulate with dark brown and yellow-brown; 

 palpi straw color, the second segment heavily shaded with brown outwardly, and 

 the third brown except at base and apex. Fore wings with rather diffuse mark- 

 ings of pale yellow- brown, especially along the fold, dorsal margin, and costal 

 margin beyond the middle, forming two conspicuous yellow splashes on costa. Front 

 and middle tibias dark brown; tarsi straw color, annulate with dark brown. 10 mm. 



Moth from July to September. Larva unknown. 

 Southern Connecticut. 



8. G. minimella Ely. Fore and hind wings each with a dorsal vein lost. Fore 

 wings dark mouse-gray with perceptibly paler costal third, cut by very faint 

 costal striations, especially on middle half of costa. Palpus on inner side white, 

 with a broad blackish band on third segment; second segment on outer side with 

 a blackish tip, third mostly blackish with a white tip. Unlike rhoifoliella in the 

 lack of a whitish costa and different palpi. 9-9 y> mm. 



July and August. Larva unknown. 

 Southern Connecticut. 



9. G. flavella Ely. Yellowish tan; face and palpi pale yellowish; vertex with 

 purplish iridescence. Costa bordered with bright straw color ; hind wings and 

 fringes yellow-gray, the apical fringe straw-color, intermixed with tan. Legs 

 as usual. 10 mm. 



July. Larva on Myrica cerifera in June. Mine at first linear, then a small 

 blotch (up to 2 by 4 mm.). Cone formed by rolling the tip of a leaf downward. 

 Southern Connecticut. 



10. G. violacella Clemens. Head and antennas purplish brown; face white; 

 palpi pale, with second and third segments each heavily dark-tipped. Fore wing 

 with costal third light yellow r except at apex, the rest light brown; a dozen dark 

 points on costal edge. All . the dark portions heavily shot with violet. 8 mm. 

 (desmodifoliella Clemens). There is also a darker phase with the yellow costa 

 extending only two-thirds way to the apex, and the third tarsi shaded with gray. 



The larva feeds on Desmodium, at first in a small linear mine, then in a tenti- 

 form one; later rolling down the edge of a leaf from the tip. The moth emerges 

 in August. It is generally distributed. 



The remaining species of this group all show more or less clearly a triangular 

 golden patch on the costa, before the middle, or a larger and irregular patch. 



11. G. burgessiella Zeller. Fore and middle tibia? dull black, contrasting with 

 the whitish tarsi and whitish hind legs, as in all this series. Face silver white 

 to level of antennas, vertex brown. Thorax brown; palpi white with a short black 

 tip. Fore wing umber brown, with purple iridescence, the more basal golden 

 spot comma-shaped or semicircular, with the straight or concave side outward ; 

 marked with dark dots on costa. Postmedial spot nearly quadrate, twice as long 

 as wide. No subterminal bars on costa. Fringe fuscous with faint lines in apex. 

 11-14 mm. 



Moth at the end of July and in August; apparently rare. Caterpillar on Cornus. 

 in July; at first in a linear mine, then a blotch, then a cone formed by rolling 

 the tip of the leaf downward. 



Cocoon formed outside the mine. This name has been frequently applied to a 

 variety of dark purple Gracilarias without a pale base to the inner margin, lint 

 seems unquestionably to belong to the species described above. 



Massachusetts; Connecticut. New York: Ithaca. 



12. G cornusella Ely. Similar to G. burgessielia, smaller; ground blackish, 

 with faint iridescence; first golden spot normally quadrate, extending to fold, 

 not large; second spot minute, separated from the first by twice its diameter. No 

 subapical costal dots. Fringe and apex immaculate dark brown. Antennas darker 

 than G. burgessiella. 10 mm. (burgessiella of authors).
