^ White, with hlacld&h markings. Fore-wing : apex "produced and 

 pointed ; costa edged with 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 blackisli 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
