fold, its inner edge is sharply incised above middle, the outer edge is convex, with 

 an obscure spur pointing toward costa from its middle. There is a similar brown 

 shade between end of cell and termen, with a narrow projection touching costa at 

 outer fifth, below costa it is much enlarged and rounded with two obscure spurs touch- 

 ing termen about the middle ; both of these brown shades are horizontally streaked 

 with darker brown on the middle of wing, and edged with black on the inner cne, 

 forming a conspicuous dark discal streak, the space between them, or upper half of 

 wing is silvery gray, overlaid with pink ; costal edge of outer half narrowly yellow, 

 with two fuscous dots between the brown shades and two larger ones between the 

 outer shade and apex. Cilia concolorous, with a darker basal line and a paler spot at 

 end of each vein along the termen. 



Hindwing. — Cinereous gray lighter basally, underside light cinereous, with ver- 

 tical fuscous reticulations on outer half. Underside forewing, smoky fuscous, with 

 a fine light line before cilia and the latter spotted with whitish. 



Five specimens, Oak Station, Pittsburg, Pa. (Fred. Marloff), 

 July 29 to August 8. Nearest P. nonlavana Krft. most easily distin- 

 guished by the dark, horizontal discal streak. 



Commophila? umbrabasana, new species (PI. Ill, Fig. 2). 



Male. — Expanse 14-17 mm., female 20 mm. 



Head pale ochreous ; palpi darker and shaded externally with brown, extends 

 beyond head nearly twice width of eye, second joint tufted above, flatly triangular, 

 scales rather compressed; apical joint very short, obtuse, light brown, paler at tip 

 and with a few darker scales at its base ; antenna, basal joint enlarged with com- 

 pressed scales, brown on basal half, pale ochreous outer half, beyond basal joint it is 

 ciliated on lower side, ciliations I, color whitish brown; thorax brown, same shade 

 as basal sixth of forewing; abdomen light grayish ochreous; legs same color, heavily 

 dusted with blackish brown, posterior tibire tufted below. 



Forewing. — Very pale fawn, or light ochreous brown, vertically strigulated with 

 dark brown, these dark scales tend to form a more or less well-defined triangular dorsal 

 spot, beyond middle, sharply defined above by outer end of fold ; in some specimens 

 the inner and outer edges of the spot are heavily overlaid with leaden metallic. The 

 basal sixth is brown, with a bluish irridescent hue in certain lights. The costa is 

 lightly marked by the darker strigulation, four spots on outer third are the most dis- 

 tinct. Above the dorsal triangular spot is a conspicuous brown dot, on the lower 

 angle of cell, this is absent on specimens that are slightly rubbed. In some speci- 

 mens the apical third is heavily strigulated with grayish fuscous, this shade margining 

 both costal and dorsal edges to before middle. Cilia light ochreous yellow. 



Hindwing. — Above and beneath light grayish ochreous. Underside forewing 

 shining, light coppery brown.
