LEPIDOPTERA OF NEW YOBK AND NEIGHBORING STATES 315 



margins with blackisli, and with a weaker streak below the fold. Outer part of 

 wing a little darker along costa, with distinct discal dots and terminal dots. 

 11 mm. 



August. Unknown to me. 



Hazelton, Pennsylvania. New York: Rock City. 



6. PLOIOPHORA Dietz 



Palpi of male closely upturned nearly to middle of front, lying in shallow 

 grooves on the lower part of the face, and roofed over by the long, overhanging 

 vestiture (usually falling forward at death) ; second segment with a large 

 obliquely oval sensory area on inner side; third segment small. Female palpi and 

 wing characters as in Pigritia. 



1. P. fidella Dietz. Fuscous gray, smooth and shining; aritemedial fascia nearly 

 straight, diffuse, and very slightly inwardly oblique from cell to inner margin, bent 

 on cell and slanting in to costa also ; the fascia formed of pale dusting, and variable 

 in strength; discal dots dark, obscure; outer third of inner margin and outer sixth 

 of costa with scattered white-tipped scales, extending somewhat into fringe. 12 mm. 



June. 



I cannot distinguish P. ampla Dietz by the one rubbed type I have seen; fidella 

 is possibly a synonym of it. 



Northern New Hampshire and Parry Sound, Ontario, to Pennsylvania. New 

 York: Rock City. 



7. PIGRITIA Clemens 

 (With Epigritia Dietz) 



Palpi of male practically obsolete (fig. 179), and of female short and porrect, 

 with third segment variable in length but generally shorter than the second. 

 Antenna? not modified. Fore wing (fig. 177) with cell set obliquely in wing, even 

 more noticeably than in the Blastobasinae ; Cu, short and running straight to inner 

 margin. Hind wing sharply lanceolate, half as wide, with R and M decidedly 

 divergent, M 3 connate with CUj, the cell very weakly closed, M 3 and Cu t rarely very 

 shortly separate at extreme margin, normally fused. The genus Epigritia was 

 based on the relative shortness of the female palpi, a character that has proved 

 intangible.

4. With a complete dark discal bar; antemedial band broad and con- 

 trasting 4. mediofasciella. 



4. Two discal dots, prominent in a white shade 3. laticapitella. 



4. Discal marks obscure; antemedial band narrower, vague, and very 



faint 1. confusella. 7. angustipennella. 9. spoliatella.
