Larva, when full grown, quite three-quarters of an inch in length ; the anterior 

 segment contractile ; rather stout ; of the usual onisciform shape, but much stouter 

 than the larvas of Arhopala rama, Kollar, A. dodonasa, Moore, and A. ganesa, Moore, 

 or of Zephyrus hirupa, Moore, for example, being roughly cylindrical instead of 

 flattened. Head globular, very small, retractile, and, when protruded, singularly like 

 that of a tortoise. Outline from above, a hexagonal cylinder (one visible side of 

 which is dorsal, two sub-dorsal), very slightly narrowing towards the head ; segmental 

 folds deeply marked ; the spiracular and sub-dorsal ridges very deeply serrated. The 

 humps are sharply pyramidal. Of these there are two unbroken series on each side, 

 one sub-dorsal and one spiracular. The sub-dorsal series consists of eight humps, 

 continuous from the third to the tenth segment. The spiracular series consists of 

 eleven humps, continuous from the third to the thirteenth segment. Each hump bears 

 two, three, or four short brown hairs. The texture of the skin is soft, smooth, and 

 velvety. Ground-colour purple-brown ; head dark brown, with a narrow white baud 

 across the face immediately over the mouth ; on each side of this band is a small white 

 spot. The brown colour of the head shades off into a dull yellow towards the neck. 

 The sub-dorsal and spiracular humps are of a dull crimson, and are bordered laterally 

 with white lines, which give them the shape of the teeth of a saw. The white 

 spiracular line is continuous. Posterior to the white spiracular line there is a lunulated 

 band of the ground-colour shading into pink above the claspers. Legs, claspers, and 

 abdomen of a pale blue-grey. Larva feeds at Mussoorie in the Western Himalayas on 

 Spiraea sortifolia, Linnseus. 



June 30i/j, 1894. — Larva pupated during the night. Pupa half an inch in length, 

 stout, of a very dark brown colour. July 20th. — Imago emerged to-day.

de Niceville says he has bred the larva in Calcutta from Antidesma gsesemhilla, 

 Mull, a deciduous bush growing in the Botanical Gardens. The larva and pupa 

 agree exactly with the figures of an undetermined species given in Horsfield and 

 Moore's Cat. Lep. Mus. E.LC., pi. 12, figs. 4, 4a, and which is probably i^opa^a varuiia, 

 Horsfield ; the larvae are attended at all stages by a black ant, Cremastogaster sp. The 

 larvae feed on the just opening leaves, buds and flowers of the bush, and resemble 

 them so closely as to be very difiicult to find, though they are easily obtained by beating. 



Habitat. — India, Ceylon, Burma, Andamans, Borneo. 



Distribution. — A common species ; we have many examples of both sexes from 

 Sikkim, the Khasia Hills, Ranchi in Bengal, Calcutta, Karwar in North Kanara, 

 Rangoon, Ceylon and the Andaman Islands ; Betham records it from the Central
