"Whitish grey, venation blackish. Primaries have a small 

 blackish basal patch, the outer edge of which is quite straight, 

 and a broad blackish central fascia, both edges are undulated, 

 but most prominently so exteriorly, in the centre of the 

 costal portion there is a diffuse spot of the ground-colour 

 abutting on the black discal spot, and there are traces of 

 similar pale spots below ; the outer marginal area is clouded 

 and suffused with blackish, and is traversed by a pale wavy 

 submarginal line, which is whitish near costa and inwardly 

 edged with blackish throughout, from this edging black 

 streaks are projected along the nervules. Secondaries have 

 the basal area and outer marginal border darker ; the vena- 

 tion also is dark on basal area. Fringes grey, preceded by 

 an interrupted blackish line. Under surface pale grey : 

 basal two thirds of primaries, also apical area, and broad 

 central fascia of secondaries smoky grey ; submarginal line 

 of primaries whitish towards costa, darker towards inner 

 margin ; beyond the fascia of secondaries the venation is 

 marked with blackish.
