species, was taken on the summit of Mt, Japvo, 9890 feet, the 

 highest point in the Naga Hills. 



Zephyrus pavo.

A single female from Margharita. I cannot be absolutely certain 

 (as the abdomens of both this and of the type in Mr. Knyvett's col- 

 lection now before me are somewhat damaged), but have little doubt, 

 notwithstanding Doherty's remarks, c/. J. A. S. B. Iviii. pt. ii. p. 130, 

 that both specimens are females, and their coloration alone would 

 make it almost certain. 



It is curious that no species of this genus has yet been taken in 

 the hills of Burmah, as its distribution would certainly lead one to 

 expect it to occur there.

Occurs at Margharita, also in the Naga and Karen Hills, and at 

 Momeit, extending in all cases to a lower level than the other species 

 oi Ilerda. In Chittagong, Doherty has taken it at sea-level.

This is the green species common in Sikkim from 5000 to 7000 feet 

 which I supposed to be J. androcles. I have it from Kulu and 

 Nepal ; numerous specimens were taken in the Naga Hills not below 

 6000 feet. These differ from the Sikkim specimens in having the 

 wings in some cases almost without the green shining scales v?hich 

 cover a large part of the wings in Siiikim, and these scales seem 

 of a purer green without any blue tinge; but I cannot see my 

 way to distinguish them, as the amount as well as the tinge of 

 the green scales varies. I have two specimens from "Western China, 

 taken by Pratt at 5000-6000 feet, which agree with the Naga 

 males. I cannot distinguish the females from those of I. brahma, 

 with which this form may possibly interbreed, as the two species 

 occur together in Sikkim, though both here and in the Nagas the 

 range of I. brahma seems to be rather lower.
