﻿portion of the Northern Moluccas. A closely allied sp. J 

 if not avar. is also an inhabitant of Batjan and the Island 

 of Oby, N.E. and by N. of the same island. The splen- 

 did Ornithoptera Crcesus is an inhabitant of Batjan, and 

 its close ally 0. Lydius with its curious female, of Djilolo. 

 Batjan is also somewhat rich in Pieridse, specially the 



Delias group, and the graceful Celestina or lavender-and- 

 yellow group. 



I am indebted to the Hon. Walter Rothschild for the 

 opportunity of figuring this species from the Felder types, 

 which are in his museum at Tring.
