Foi'ewiny : flesh-coloured browu, tinged with olive and sometimes darkened with 

 fuscous suifusion ; middle third of wing occupied by a dark blackish brown fascia 

 crossed by several waved lines and containing the obscure cell-spot ; this fascia has its 

 inner edge formedof three curves concave basewards, the middle one large, stretching 

 from fold to fold ; all the lines basewards parallel to it — viz., the edges of a curved 

 dark band and the lines in the pale bands on each side of it ; the basal patch quite 

 small, witli three dark lines : the bands preceding and following cejitral fascia more 

 tinged with green ; submargiiial line close to margin, formed by the intcrrujited 

 jiale ends of the usual lunnles, jn-eceded by three waved dark luuulate lines : i)airs of 

 semiconfluent black dots along margin at the vein-ends ; fringe concolorous with 

 dark mottliugs.

Underside of forewing smoky blackish, the basal two-fifths whitish ; a pale 

 bent band beyond central fascia and pale spots at apex and below vein 4. Hindwings

Fon'wiiKj : dull olive ; the rows of spots dark olive-fuscous ; all the spots finely 

 but roughly edged with pale red-speckled ochreons, whereby the whole wing assumes 

 a slightly reddish tint. The rows of spots are six in number : the first basal, hardly 

 interru])ted ; second, antemedian, of three spots, a large double one in cell and 

 beneath it, and irregular truncated ones above costal and below submedian vein 

 respectively ; third median, double towards costa, consisting of two irregularly shaped 

 costal spots, pointed towards each other, a small blotch in cell, and a large 

 elongated blotch beyond cell, the latter connected below cell with the outer of two 

 curved and angled blotches in submedian interval, which unite to form a square 

 blotch on inner margin ; fourth postmedian, slightly curved and waved, the sjiots 

 Innate and coalescent ; fifth submarginal, of rounded and irregular sjiots, j)artially 

 contiguous, the two beyond cell being smaller, those above and below them largest ; 

 sixth marginal, formed of more or less diamond-shaped blotches touching dark 

 marks at the vein-ends, an<l enclosing pale flattened ovals before the fringe, which is
