102 ME. G. T. BETHUNE-BAKEE : A EEVISION OF THE 



I have before me, from the collection of Mr. de Niceville, three specimens of this 

 species from Tounghas (Central Burma), and one from the Dannat Range, Upper 

 Tenasserim ; they differ somewhat in that they are much greyer in the colour of the 

 underside, and are also slightly smaller, but otherwise there is no difference whatever. 

 From alesia Felder it differs in that it lacks a tail, and that its colour above is violet- 

 blue, not pale azure as in Felder's insect, whilst beneath it is much more uniform in 

 general tone.

Hah. Philippine Islands ; South Andaman Isles. 



Expanse, d & 2 , 38 mm. 



This species has a more variegated appearance beneath than oberthuri Stgr., the 

 dark spots being darker, and the ground-colour not quite so dark, whilst the pale 

 edging to the spots is much more marked than in Staudinger's insect, and it has also a 

 good many pale scales scattered more or less over its surface. De Niceville's loimberleyi 

 falls as a synonym to this. 



Akhopala ocrida Hewitson.

Hab. Philippines. 



Expanse, 6 & 2 , 39-42 mm. 



On the upperside this species is almost exactly like alesia Feld., but is of a rather 

 darker blue colour, while beneath the differences are greater. Ocrida is greyer and 

 much more uniform ; it has none of the light patches of pale scales, and its pattern is 

 smaller and not confluent, as is the case in the secondaries of alesia ; there is also a 

 distinct black lobe-spot and some metallic scaling in its neighbourhood, which is 

 almost entirely (though not absolutely) wanting in Felder's insect. Hewitson says 

 " this species and A. corinda scarcely differ on the underside." This is not quite 

 accurate ; there may be just at first sight a superficial resemblance, but it is exceedingly 

 superficial. The two species are not really at all difficult to separate.
