ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 43 



Upper side of fore wing grayish brown with a blackish shading at basal 

 area in certain lights ; also, under same conditions, there is the appearance 

 of a discoidal spot of blackish. At first glance, however, the wing appears 

 to have no markings. Hind margin fringed with hairs of a color slightly 

 lighter than ground color. 



General color of hind wing the same as of fore wing. The hind margin, 

 within its fringe, has a slight darkish thread. At end of lower median 

 nervule is a short, delicate tail, nearly one-sixteenth inch long, dark-colored, 

 with a white point. At the margin, in interspace above this, is a black spot 

 surrounded on basal side by a semicircle of reddish brown, and, in the inter- 

 space below another similar spot, but much smaller than the first. 



Under side of fore wing steel gray with a brownish tinge. Basal area 

 dusted with bronzy scales. At hind margin, running from apex down to 

 lower median nervule, is a double line of interspacial spots of a color slightly 

 darker than ground color, but all of them very indistinct. On close exam- 

 ination these spots are seen to be edged with whitish. Beginning at subcostal 

 space, at a point one-third distance from apex to base, is a line of six inter- 

 spacial semi-circles of a rich red brown color, extending downward to lower 

 median nervule. These are edged with whitish on outer edge. 



Under side of hind wing same ground color as fore wing. Basal area 

 dusted with bronzy scales. The marginal border and the double line of 

 indistinct spots is the same as on fore wing, excepting that the spots in in- 

 terspaces next above and below the tail are black, surrounded on basal side 

 by a siemi-circle of reddish brown. Beginning near apex and extending across 

 the wing to near the centre of inner margin, is an irregular line of rich red 

 brown, having a white edge on outer side. At the submedian nervule this 

 line forms a V.
