Distribution.— “ This species seems to be confined to the island of Great 
Nicobar, where the late Mr. F. de Roepstorff and Mr. E. H. Man have each obtained 
two males. Mr. Doherty also obtained both male and female at Great Nicobar, who 
states that the female, when flying, resembles the white C. Thyodamas, for which he 
at first mistook it ” (lx.). 
Our illustrations of this species on Plate 307 are reproduced from Mr. de 
Niceville’s figures.
