1 S and 3 9. — Male aiitemuv ciliated, the hai^^ long, making the an- 

 tenntr look as if finely pectinated. Ground-color of body and wings ochreous- 

 white. Fore wings speckled densely with dark reddish-brown (of the same 

 hue. ;is Eufidunia iiotatana). The fore wings are crossed by three irregular, 

 indistinct l)ands, made up of dark reddish-brown patches, with lighter spaces 

 between where the dark scales are less numerous. The basal band is nearly 

 as broad as the body is thick; it is straight, diti'use, broken. The middle of 

 the wing is clearer, though thickly speckled with dark scales; discal dot dis- 

 tinct. Just beyond, a broad, oblique, broken, diti'use band, interrupted by 

 the ochreous veins. Beyond this is a clear, whitish band, forked on the sub- 

 costal vein, and lending an oblique whitish streak to the apex. A submar- 

 ginal, white, scalloped line, tlie scallops tilled with niasses of brown, forming 

 a row of rounded, conical spots. The margin of the wing is brown, with 

 white flakes; a row of distincl, l)lack, marginal spots. Fringe brown, white 

 o])p()site the black marginal spots. Hind wings whiter than the anterior 

 pair, the dark scales forming scattered dots, and also arranged in three extra- 

 discal, diffuse, irregular bands, the submarginal one the most distinct, and 

 edged externally with a white, scalloped line. A dark, interrupted, distinct, 

 marginal, blackish line. Beneath, lore wings witii the bands faintly re-appear- 

 ing; the marginal spots on l)oth wings as distinct as above. Hind wings 

 with the brown spots and speckles more distinct than above ; the middle of 

 the three extradiscal bands is more distinct than the others. Discal dols 

 distinct on both pairs of wings. Abdomen concolorous with the liiiid wings.

 fore wings and ciliated male anteimae. Otherwise, the markings resemble
