fi'Diii lievmiJ luiJdle of costa to beyond middle of inner margin, nearly 

 vertical, or slightly outbent at middle, in the single ? distinctly angled on 

 vein 4 ; snbmarginal line irregularly waved, angled inwards below costa and 

 interrupted between veins 3 and 4 ; central area olive-brown; basal area the 

 same, but generally mt)re mixed with paler scales, the subcostal, median and 

 submedian veins sometimes slnnving pale across them ; subniargiiuil line preceded 

 by ii dark irregular shade, interrupted between 3 and 4, and of varying 

 intensity, generally forming a dark blotch on costa and at iimer margin ; in 

 the two male examples the white is fringed with yellowish ochreons thickly 

 speckled and striated with fnscon? ; in the ? the outer area of central fascia 

 and the streak interrupting the snbmarginal line between veins 3 and 4 is dull 

 reddish ; in all cases the upper half of marginal area is darker than the lower; 

 a series of black marginal triangles between the veins ; fringe dark green or 

 fuscous, with slender dashes of paler, varying in colour according to the tint 

 of the ground colour ; cell-spot lilack, indistinct. 



Ilindirinij : fuscous cinereous, with a paler cnrved snbmarginal baud preceded 

 by a dark ciu'ved line, the darker hindmargin with a pale marginal blotch 

 between veins 2 and 4 : fringe in the ? rufous-tinged, in the two $$ yellowish 

 ochreons. 



Underside duller, but witii all the dark and pale markings indicated.

 and December 1901, wet season (Ockenden). 



In character of markings, shape of wings and body, and all points of 

 structure except the palpi, this species is a true Ischnoptcris ; the palpi, 

 however, have the terminal segment of unusual length and slenderness, and 

 agree in this particular with the genus Mimoprora hereafter described.

c?. Foreicinij : moss-green and pinkish grey, mixed with fuscous and thickly 

 black-speckled, the veins rather paler ; the inner and double median lines very 

 obscure, disposed and shaped as in chlorocb/xtnta Guen., of which it may be a local 

 form. Be3ond the outer arm of the median line, which bounds it inwardly, a large 

 white blotch reaches from costa, where it is narrower, to the median vein ; on 

 its outer edge lies the black cell-mark, the whitish marked snbmarginal line is 

 preceded on costa by a diffuse whitish jiatch ; the margin of the wing before 

 the fringe is very pale green and pinkish grey, in one instance mixed with 

 whitish scales.
