144 ME. G. T. BETHUNE-BAKEK : A EEVISION OE THE 



This species, from its size and general appearance, looks scarcely in keeping with its 

 near neighbours, being about half as large again, but the underside pattern is so very 

 similar that I cannot place it elsewhere ; it may at once be recognised by its 

 large size.

Expanse, d 37-40, $ 32-40 mm. 



The width of the borders is variable. Specimens from Tilin Yaw (Burma) have 

 the borders decidedly wider than those from Tenasserim, but in all cases they are 

 much wider than in aberrans de N. ; the blue is also darker and the size decidedly 

 smaller. From paraganesa de N. it may be distinguished by its larger size, its darker 

 and very much more extensive blue. I have the type specimens now before me, and 

 they agree precisely with those of arisba de Niceviile. 



Referring to the original descriptions of this species, I have not been able to 

 examine the genitalia of them, but I have no doubt in my own mind that the specimen 

 with the white spot, described as a male, is the female, and that the one with the 

 darker and larger blue area is the male which was described as the female ; the same 

 remark also applies to both the text and the plate in Mr. Grose-Smith's ' Rhopalocera 

 Exotica.'

Expanse, c? & ? , 40-44 mm. 



This species on the upperside is very distinct, but on the underside it is almost an 

 exact copy of paraganesa de N., only very much larger. It is also larger than birmana 

 Moore, and of a much paler and rather brighter blue, whilst the female has a very 

 marked patch of white at the upper extremity of the cell of the primaries.
