$ White, %oith large hiiicl-marginal nervidar black spots, united in 

 fore-wing to form an imoardly strongly dentated border, but all separate 

 in hind-iuing ; a submarginal roio of small intcr-nervidar black spots, 

 more developed in liind-vnng. Fore-iuing : costal margin with a narrow 

 black edging, scaled with white at and near base, and rather abruptly 

 widened a little before apex ; hind-marginal macular border continuous 

 as far as second median nervule, its component spots more or less tri- 

 gonate and inwardly acute ; a separate spot at extremity of first median 

 nervule, and a very small narrow one at extremity of submedian ner- 

 vure ; spots of submarginal row four, rounded, — three between costa 

 and lower radial nervule, very close to (or even touching) apical black, 

 — the fourth (often indistinct) apart from the rest, between third and 

 second median nervules ; base with a sub-metallic gloss, and with the 

 under side red faintly indicated. Hind-wing : six hind-marginal spots 

 of moderate size, rather widely separated, rounded, from second sub- 

 costal nervule to submedian nervure, — the third, fourth, and fifth larger 

 than the first and second, and the sixth much the smallest of all and 

 sublinear ; very rarely the trace of a seventh spot at extremity of first 

 subcostal nervule ; seven small spots in submarginal row, between costal 

 and submedian nervures, — of which the seventh is always, and the 

 fourth and sixth usually, very indistinct ; a faint ochrey-yellow edging 

 on inner margin for a little distance from anal angle. Under side. — 

 Hind-wing and smcdl apical patch of fore-wing creamy ochreous-yellow ; 

 hind-marginal spots much smaller and narrower, but submarginal spots 

 larger, darker, and better defined than on upper side. Forc-u'ing : a 

 narrow basal suffusion of orange-red, outwardly radiating slightly on 

 the white ground, but not reaching quite to middle of discoidal cell ; of 

 the seven hind-marginal spots, the u.pper four (bordering apical yellow) 

 are very small, or even obsolete, but the remaining three moderately
