angled where it resolves itself into its arm-like supports ; the hooks are sharply bent at 

 their muscular attachment inside the tegumen, whence they project horizontally in a 

 slight curve ; the clasps are bilobed, the upper lobe being anvil-shaped, the upper fore 

 extremity being sharply pointed and very highly excavated internally, whence it is 

 projected into the long finger-shaped lower lobe, which has an upward curve. The 

 penis is very long, with a contrary angle fore and aft, with a large trumpet-shaped 

 orifice much expanded on its outer lip. 



Habitat. — Sikkim, Assam, Nepal. 



Distribution. — Moore records it from Nepal, de Niceville from the Chittagong 

 Hill Tracts, we have it in our collection from Sikkim and the Khasia Hills.

Imago. — Male. Upperside rich emerald-green like A. eumoljjJms. Forewing with 

 a fine black costal line, the outer marginal black Ijand narrow and even. Hindwing 

 with the costal and outer marginal bands much narrower than in eumolplius, in some 

 examples the latter is of almost even breadth, running in one or two places a little up 

 the veins. Underside generally darker than in that form, and of a fairly uniform dull 

 brown colour, the spots similarly disposed, but all much larger, the anal spots are larger 

 and deep black, and are capped by brilliant metallic green scales, wings more squarely 

 shaped than in eumolplius, apex not so produced, costa more highly arched, outer 

 margin less oblique. 



Female. Upperside lilac-blue, brighter blue than in eumolplius, the black outer 

 marginal bands in both wings narrower. Underside like the male, the black spots and 

 green scalings at the anal angle similar. 



Expanse of wings, $ $ l^^ to 2yV inches. 



Habitat.— -Burma, Malay Peninsula, Borneo, Java, Sumatra. 



No doubt one of the forms of eumolplius, but not eumolplius, which does not appear 

 to occur out of India ; we cannot but believe that inaxwelli is the true female of 

 farquhari, they occur together, and the colour and markings of the underside are 

 exactly similar.
