IscHALis, "Wlk. xxvi. p. 1749.

IscHALis coLOKATA, sp. n. (Plate XXXn. fig. 26.) 



d . Fore ^vings pinkish ochreons, but the ground-colour is almost 

 wholly overrun by a suffusion of tawny, the pale interspaces being 

 likewise dappled with spots of the same tint; no 1st line ; exterior 

 line at -g- pale silvery lilac, nearly parallel on the whole to the hind 

 margin, forming a small sinus outward below the costa, and a 

 similar one inwards above the inner margin ; tliis line is followed 

 immediately by a dull olive-green fascia, which is succeeded by a 

 paler, narrower, somewhat interrupted fascia of the ground-colour, 

 beyond which the whole marginal area is tawny; the nervules 

 beyond the exterior line are themselves marked with the same tint 

 of silvery lilac, dotted in places with dark brown ; the whole basal 

 5 is dark tawny, divided on the costa by a small paler space ; a 

 narrow tawny blotch lies on the costa in the middle ; cell-spot 

 diffuse, roundish, dai-k brown. Hind wings like fore wings, but 

 the basal area only dappled sparsely with tawny spots, with the 

 commencement on the inner margin of an irregular rust-coloured 

 line. Head, thorax, and abdomen ochreous suffused with tawny. 

 Underside like upper, but more brightly coloured — the tints of 

 ochreous, tawny, and green much more brightly contrasted.
