39. Terias nicobariensis . 



Terias nicobariensis. Felder, Verh. zool.-bot. Ges. Wien. xii. p. 480

 Terias phanospila, Felder, Keise der Nov., Lep. ii. p. 209 (1865). 



Andamans, Nicobars, Java, Sumatra, Flores (coll. Hewit- 

 son), Borneo, and the Philippines. We have a female appa- 

 rently referable to the intermediate form of this species, but 

 said to have been taken in Ceylon. 



To my mind T. nicobariensis is more nearly related to 

 T. silhetana than to T. suava (with which, under the incorrect 

 name of T. hecabe, it has been associated by Indian workers) . 



T. phanospila was based upon old discoloured males from 

 Java; we have exactly similar specimens from Horsfield's 

 collection. This is the dry-season form of the species.
