beneath whitish, l-egs covered with whitish hairs, brownish at ends. Anten- 

 nic blackish, with small white annulations at base of each joint ; club above 

 blackish, tipped with light brown, below light brown down to joint. Wings, 

 above, dark brownish gray, with white and grayish white spots, hind margins 

 with a fringe of dark brownish gray. Hind margin of primaries edged with 

 a dark line, just within which, in interspaces, is a row of indistinct darkish 

 spots, absent in some specimens. The dark brownish gray covers marginal 

 area, arid is dusted and irregularly shaded with grayish scales. On costa one 

 fourth distance from tip to base, between the subcostal nervules, three (some- 

 times two or one) small white spots. Across centre of wing, extending from 

 edge of costa across end of discoidal cell down to submedian nervule, a whit- 

 ish band of consecutive spots, of irregular form and varying distinctness, 

 sprinkled more or less with brownish scales. In some specimens this space 

 shades off into ground color, in others the edges between spots and ground 

 color are distinctly marked, and bordered with a darkish line. In centre of 

 cell, an irregular whitish spot of same character ; between this spot and the 

 spot at end of cell, and below submedian nervule, an irregular whitish spot, 

 dusted more with brownish scales. Base dark brownish gray, with some 

 grayish scales. The suffusion of the ground color is more marked in some 

 specimens than others, rendering an accurate general limitation of the spots 

 difficult. Some specimens show a slight yellowish tinge on white spots. 

 Ground color of secondaries a blackish brown, of more distinct character than 

 the ground color of primaries. Costa white. Hind margin edged with a 

 dark line, within which, in interspaces, is a row of white specks, sometimes 

 absent, which, at anal angle, are transversely elongated, forming an indistinct 

 line from inner margin to submedian nervule. Within these, one third distance 

 to base, a row of brownish spots, extending from costa to inner margin, parallel 

 to hind margin, but not in line, and the one near centre larger than the others, 

 and drawn nearer to cell. Within these, across centre of wing, a prominent 

 V, hitish band, forming an extension of the same on primaries, but of purer 

 white, ending at submedian nervure. Basal area, of ground color, but toward 

 inner margin covered with light grayish hairs, which extend along margin to 

 anal angle. Beneath, general color is grayish white, with a very slight yellow- 

 ish brown tinge, and showing shadows of the markings above. Costa of prima- 

 ries marked with darkish brown and white, reflecting markings above. Hind 

 margin edged with blackish brown, and within, covering one third of marginal 

 area, darkish brown, with a row of white specks in interspaces. Costa of 

 secondaries white, same as ground color. Hind margin edged with a line of 

 blackish brown, shading off into ground color. In space below submedian nerv- 

 ule, the dark markings of upper side show more prominently than elsewhere.
