Wings, aboce, greyish creamy buff or grey, shaded with brown, crossed by 



black lines and bands. Forewing : traces of a basal and a snbbasal line at costal 



margin ; three antemedian lines, the proximal one feebly marked, all curving costad 

 in front ; a small whitish stigma with a thin brown border ; three parallel lines 

 on disc, almost regularly crenate, intersj)ace between the first and second more or 

 less blackish ; an interrupted ])ostdiscaI line almost evenly curved from costa to 

 M'^ ; submarginal line indicated by black halfmoons upon R^ and M^, interspace 

 between first halfmoou and postdiscal line blackish (as in Jasminearum, P.J/orestan, 

 etc.) ; an oblique apical line joining the postdiscal line between SC and R' ; two 

 black discal streaks R' — M- penetrating basad into the broad pale discal intersjiace : 



fringe with creamy white spots. Hiudwing : a large but ill-defined black basal 



patch ; two parallel discal bauds, the first the broader, of even width, situate just 

 outside the cell, the second crenate, consisting of contiguous halfmoons ; a broad 

 marginal band, distally shaded over with grey scaling, a black dash running through 

 the grey marginal scaling at the apex of the wing. 



Underside : ground-colour as above. Forewing : much more shaded with 



brown than above ; of the discal lines the inner one indistinct, the others crenate, if 



more distinct. Hiudwing : a discal band just outside the cell, curving basad at

 also not differing from that oi Jasminearum. 



? . Vaginal plate of undata cinerea (PI. XX. f. 'J) similar to that of

 vaginal plate recurved in middle, the upper (or hinder) edge triangularly sinuate, 

 with a (sensory) hair.
