Lepidoptera of New York and Neighboring States 177 



darker. Fore wing with costal triangle pale straw yellow, almost obliterated with 

 dark purple suffusion; fringe gray, almost concolorous at apex with two dark 

 lines. 13 mm. 



The moth is distinguished from coroniella by the darker coloring. It flies in 

 September; doubtless wintering, and reappearing in April. 



The larva occurs on alder in August, at first on the under side of a leaf, in 

 a linear mine; which ends in a small blotch, which is usually near the margin; 

 then later in one or two shelters formed by turning down the edge of a leaf; 

 and finally, in a cone at the apex of the leaf. The cocoon is formed outside the 

 mine. 



28. G. atomosella Zeller. Thorax and fore wing heavily dusted and shaded with 

 blackish, on a pale ochreous ground; fore wing with pale striae toward costa and 

 inner margin; one of these, before the middle of the costa, being the most distinct 

 marking, and extending obliquely out almost to the inner margin. Base darker. 

 Head white, somewhat tufted behind. Palpi black with two white rings on second 

 joint, and base of third joint white. Maxillary palpi with white dots. 14 mm. 

 (atmosella Ely — misprint). 



This species is unknown to me. 

 Texas; "Atlantic States" (Ely). 



II. Palpus with a triangular tuft on under side of second segment (Coriscium). 



29. G. cuculipennella Hiibner. White, with oblique fasciae formed of black- 

 barred scales, and mixed with brown scales, which concentrate at the edges of 

 the fascia?, forming brown lines; base powdery gray; basal half of wing with 

 two fascia?, extending obliquely outward, the first heaviest on inner margin, the 

 second stronger, and usually ending just above the inner margin ; a similar medial 

 fascia. Outer half of wing with diffuse spots and short vertical fascia?; fringe 

 with dark-tipped scales, gathering in three or four lines. Head, thorax, palpi, 

 and tibiae powdery gray, barred with white, the tarsi hardly lighter. Inner side 

 of palpi white. 10-14 mm. 



Larva on privet. 

 Europe. 



American records probably apply to fraxinella, which may be only a race of 

 this species. 



30. G. fraxinella Ely. Similar. Powdery gray areas more diffuse, the scales 

 mostly finely white -tipped; usually with the fasciae broken up, and obscure; 

 rarely with fasciae contrasting and black, but broken into spots. Fringes more 

 suffused with gray than in G. cuculipennella ; head and thorax darker. The white 

 ground color is reduced to a large number of spots, many of them rounded. 

 12-14 mm. 



Moth in July and May, the latter doubtless specimens which had emerged the 

 preceding fall. Caterpillar on ash and apple, in the usual cone, in June. This 

 may be a synonym of G. pwradoxa Frey and Boll. 



Connecticut. New York : Ithaca. 



31. G. paradoxa Frey and Boll. White, heavily and rather evenly dusted with 

 finely black-tipped, clay-eolored scales, leaving a white antemedian fascia across 

 the wing, and obscure, alternately light and dark mottlings along the margins 

 outwardly. Head rather more lightly dusted, and palpi more heavily, except 

 the tip of the second segment and base of the third. 12-15 mm. (Parectopa.) 



Moth in April and early May. Larva unknown. 

 Boston, Massachusetts; New Brighton, Pennsylvania. 



32. G. quercinigrella Ely. Similar to G. fraxinella, powdery gray. Palpi only 

 lightly dusted; fore and middle tibiae red-brown; tarsi white, ringed with red- 

 brown; hind legs yellowish; the femora and coxae shaded with red-brown. Fore 

 wing with markings diffuse; base much paler below fold than above; anteme- 

 dial fascia oblique outward, pale gray; outer part of wing with obscure, con-
