140 ME. a. T. BETHTJNE-BAKER : A REVISION OF THE 



Hal. Sikkim ; Sylhet ; Khasia Tlills; Cherra Punji, Margaree; Pegu; Burma; 

 Mergui. 



Expanse, Z 30-32, ? 29-30 mm. 



This species can be easily recognised from asopia Hew. bj its much smaller size 

 and its blue colour (asopia being quite violet in tone), whilst the quite different colour 

 beneath, yellow and purplish, will at once separate it. The genitalia have the 

 tegumen short and of a heavy scimitar-shape; the clasps are bilobed, and the penis is 

 a straight tube.

 Hal. New Guinea. 



Expanse, d 44-52, ? 46-48 nun. 



This very beautiful species has been exceedingly rare until within the last few years, 

 but recent collections from New Guinea have contained considerable numbers. It 

 has been somewhat difficult to give it and the following species (A. acron Hew.) their 

 right position; but the latter is evidently near to admete Hew., so this will be their 

 best position, though the brilliance of the blue of azenia Hew. at first makes it look 

 out of place. 



There is no difficulty in recognising the species at a glance, the lustrous almost 

 morpho-like blue of the upperside, and the beautiful white underside just tinged with 

 faintest pink, beneath which the usual spots and bands (nearly allied in position to 

 those obtaining in admete) show through as a sort of purplish-lilac colour, should 

 make the insect distinguishable at once. It is a beautiful species, but apparently 

 with about the most limited range of distribution in the group.

Hah. Batchian. 



Expanse, 6 & 2 , 46 mm. 



This insect is a close ally of the preceding species, but can be distinguished at once 

 in that the blue colour of the upperside is decidedly darker, whilst beueath the colour 

 is uniform greyish brown, with the spots and bands a trifle darker, outlined sharply 

 with fine whitish edgings. It is, I believe, a very rare species; I have only seen about 

 half a dozen examples in all the collections that have passed through my hands, ami 

 one of those is in my own collection. Though Hewitson's figure of the uuderside is 

 not good, it is quite sufficient to enable the species to be recognized. Neither this 

 nor the preceding species is likely to be confused easily with other species. I can 

 trace no records of this butterfly elsewhere than from Batchian.
