$ White, luitJi Uackish markings. Fore-ioing : apex produced and 
pointed ; costa edged witli blackish, close to base greyish ; base slightly 
diffused with greyish, and with a pearly gloss ; at extremity of dis- 
coidal cell, a black, angulated streak, united to blackish costal edging, 
and thickest at its lower extremity ; on hind-margin a blackish band, 
rather wider at apex, and ending on first median nervule, enclosing six 
very small white spots, and united by blackish nervules to an inner 
blacker, more irregular transverse band ending on second median ner- 
vure. Hind'ioing : on hind-margin a linear black edging, and from 
four to six moderately-sized, inwardly-acute black spots at extremities 
of nervules ; base greyish, with a slight pearly gloss ; a few indistinct 
traces of the dark wavy streaks on under side. 
Under side. — Fore-wing : similar in marking ; in discoidal cell a 
short longitudinal dusky ray from base ; the spots in hind-marginal

which touch the points of the lunular marks of the outer transverse row ; 
costa edged at base with bright-yellow.

suffused with greyish nearly to extremity of discoidal cell, and glossed 
with a violaceous lustre ; a short broad stripe of black from costa, at 
extremity of discoidal cell ; submarginal band joined to hind-marginal 
one, the narrow space enclosed between the two composing three or 
four yellowish spots, often indistinct ; an ill-defined blackish spot

nervure, and slightly along costa ; a black elongate mark at extremity
