 the Great Nicolar. — By Lionel de NiceVille, Esq.

(With part of Plate I.) 



The very beautiful insect described below has been recently received by 

 the Indian Museum, Calcutta, from Mr. A. de Koepstorff, who obtained it 

 at the close of last year from the island of Great Nicobar. It is the first 

 species of the genus Cyrestis that has been recorded from the Nicobar 

 group of islands, though three species have been obtained by Mr. de 

 Eoepstorff from the neighbourhood of Port Blair in the South Andaman 

 group, all of which belong to the pale section of the genus, while the 

 species now described belongs to the tawny section. It is not unlikely that 

 a "tawny" Cyrestis remains to be discovered in the Andamans, as in Sikkim 

 and elsewhere species of both sections occur together ; but it is io be re- 

 marked that the Andamans even now are exeeptionably rich in species of 

 Cyrestis. Upper Tenasserim is the only other locality where more than 

 two species are met with as far as I am aware.
