spots are also more prominent. UNpeErsiDE, both wings with 
much the same differences as on the upperside. 
Having now obtained both sexes of NV. amphion from Amboyna 
I am able to satisfactorily describe the present species, which is 
represented in my collection by a single example captured by 
Mr. William Doherty.

phous examples. 
Hasitat: Probably Nepal, Sikkim, Bhutan, teoue not Assam, and 
the Northern Shan States of Upper Burma. 
The gynandromorphous specimen here figured is in the collec- 
tion of Mr. Paul Mowis, who has kindly lent it to me for 
description, and was obtained in Sikkim by his native collectors. 
It is absolutely bilateral, the left-hand side and left fore-leg 
being male, while the right-hand side and right fore-leg are 
female, Professor Westwood having figured and described a 
specimen in which the opposite sexes are reversed, the feminine 
side being on the left, the masculine on the right. He also 
figures and deseribes a second specimen of this species in which 
the coloration of the two sexes is strangely commingled in the 
right-hand pair of wings, while the left-hand pair is entirely male, 
the body and fore-legs being masculine. Professor Westwood 
did not record the exact locality from whence his specimens came, 
but said they are in the collection of the British Museum.
