the outer edge of the baud, which is sharply defined In a black line edged 

 externally with white; this line is situated about half-way between the outer 

 edge of the pale band and the outer edge of the wing; just below the costal 

 edge, it sends oil' two unequal, subacute teeth, the lines twice as large as the 

 upper, and bordered heavily with black internally j the line curves in as it 

 crosses the discal .space ; in the first and second median spaces is a promi- 

 nent, well-rounded scallop, below which the line runs straight to the inner 

 edge, being three times scalloped in its course; beyond this line, a broad, 

 dull, purplish shade, filling in the scallops; a submarginal, interrupted, 

 white thread: a conspicuous, dark, oblique, apical streak; the usual dark 

 marginal line; fringe brown, tipped with white. Hind wings washed with 

 brown, darker beyond the single, extramedial, curved line, which has two 

 scallops, one in each of the two first median spaces. Beneath, the wings are 

 less clear than usual, being finely dusted with brown, clearer on the basal 

 half, and with two parallel lines, the outer line consisting of venular dots 

 connected by a faint line; a subbasal, black, costal patch. Legs dark, ringed 

 with whitish. Abdomen brown, with dark transverse lines above, especially 

 marked toward the base. 



Length of body, <? , 0.48, 9 , 0.45; of fore wings, 3 , 0.60, 9 , 0.63; expanse

This fine moth may be known by the conspicuous, white, mesial band, 

 and. in rubbed specimens, by the three blackish bands on the fore wings, and 

 by its olivaceous hue; also, by the dentate and scalloped, very distinct, outer 

 line, situated in the outer fourth of the wing; by the clear hind wings, with 

 a single line, and the distinct, apical, oblique line on the fore wings.
