fuscous. Fore wings white, streaked with ochreous, with a dark ochreous streak 

 at the hase of the fold, margined on the inner side with dark brown. The 

 inner border, from near the base to the tip of the wing, is closely dotted with 

 dark brown ; and on the costa, toward the tip, are a few dots of the same hue, 

 and in the middle of the wing an elongated dark brown dot ; cilia white and 

 dark brown intermixed. Hind wings dark gray. Abdomen dark gray. 



P. limbipennel la. Head pale ochreous. Labial palpi whitish : tuft dark 

 brown. Antenna? brown, slightly annulated with white. Thorax yellowish 

 white ; tegulre dark brown. Fore wings cinereous brown, dusted with dark 

 brown, witli a dark brown sinuated streak along the fold, and the inner mar- 

 ginal portion of the wing pale yellowish white, with three rounded projections

P. mollip edella . Head and thorax pale brownish ochrecus. Fore 

 wings pale brownish ochreous, somewhat paler along the costa, and dotted 

 with dark brown, with a fuscous, sinuated streak in the fold, narrowly edged 

 with ochreous gray. The inner marginal portion of the wing pale brownish 

 ochreous, with three projections toward the fold, and the inner border dotted 

 with dark broion to the tip of the wing. Hind wings dark gray ; cilia brownish

Gtkacilaria Zeller. 



G. superbifrontella . LaMal palpi yellow, tipped with brownish. An- 

 tenna? dull yellow, with very faint brownish rings. Head stramineous, 

 tinged with reddish violet on the forehead. Thorax stramineous, with tegula? 

 externally striped with reddish violet. Fore wings beautiful reddish violet, 

 with a shining stramineous patch on the inner margin at the bas'e, and a large 

 costal triangle of the same hue, reaching almost across the wing, and extending 

 along the costa from the basal third, nearly to the apex. Hind wings black- 

 ish gray ; cilia dark fuscous. 



This insect must approach very closely the European Swederella. 



The larva may be found, in the middle of July, in cones, on the leaves of 

 Hamamelis Virginica (Witch Hazel), and the imago appears early in 

 August. The head of the larva is pale green ; body pale green, darker 

 colored by the ingesta, with the tenth ring whitish, and the cervical shield 

 pale brown. 



Gr. f u 1 g i d e 1 1 a . Head and antenna? yellowish white. Fore wings white, 

 with a silvery lustre, with a dark brown blotch near the base, not extended 

 across the wing. Rather beyond the middle of the wing is a broad, dark 

 brown band, with the exterior margin darkest, and sharply angulatcd just above 

 the inner margin. The apical portion of the wing contains two rather broad, 

 dark brown costal streaks, somewhat confluent in the middle of the wing, 

 with a white costal spot between them. The extreme apex of the wing is 

 dark brown, with a white costal streak before it, and opposite the costal white 

 spot is another, at the interior angle, sometimes two not distinctly separated. 

 Hind wings dark fuscous ; cilia the same. 



Gr. venustella .Labial palpi white, with a blackish spot near the mid- 

 dle, and one near the tip. Antenna? dark brownish. Head silvery white. 

 Fore wings dark cinereous, with a purplish hue, and white along the inner mar- 

 gin from "the base to the middle. At the basal third of the wing is a small, 

 white costal spot ; three oblique, equidistant, slender white bands, dark mar- 

 gined on both sides, the first about the middle of the wing, the second and 

 third converging at the inner margin, with a white spot at the extreme apex, 

 dark-margined on both sides by short streaks ; cilia cinereous and white in- 

 termixed. Hind wings blackish gray ; cilia rather paler.
