lower half of termen; posterior part of wing beyond preceding with an 
ill-defined marginal streak of olive-ochreous irroration, which is twice 
interrupted on costa before apex and merges in the base of the preceding 
fascia; an ill-defined whitish-yellow dot on costal extremity of each first 
and second transverse fasciae. Cilia glossy olive-ochreous with ill-defined 
cloudy bands: a moderate basal, a broad median and a narrow apical 
purplish-brown band, median one extended around apex, so as to occupy 
almost entire breadth of cilia. Hind wing under 2 / 3 ; deep golden-purplish- 
bronze. Cilia pale greyish becoming darker towards tornus and on dorsum, 
with a broad purplish-bronze subbasal band throughout. 
Limen, a large transverse semiovate fold, with upper edge thickened 
and finely haired. Colhculum small. Signum rather broad, with the two 
extremities acute, its upper edge minutely denticulate. (Slide no. 1129 D, 
type.)
