and May. The sexes here differ but slightly, the dry-season form of the female being 

 alone found. The butterflies seem always to be flying from east to west, this observation 

 having been made at two places more than twenty miles apart " (J. Bombay N. H. S. 

 1898,591). Mr. H. J. Blwes records it as "common in Sikkim at low elevations 

 from April to October. The females, which are rarer than the males in their proper 

 habitat, have the habit of flying up to great heights on the mountains. I took 

 females on Tonglo at 8,500 feet, on the Kishila in Bhotan at 10,400 feet, and in the 

 Khasia Hills at the highest peak on the Shillong plateau, 6,400 feet ; but saw no 

 males in any of these places " (Tr. Ent. Soc. 1888, 419). Mr. L. de Niceville says 

 it " occurs in Sikkim from the level of the Terai to over 10,000 feet elevation, and 

 flies from April to October " (Sikk. Gaz. 1894, 169). Col. C. Swinhoe recoi-ds it as 

 " common in the Khasia Hills, also Shillong and Cherra Punji" (Tr. Ent. Soc. 1893, 

 310). Dr. G. Watt obtained it at Manipur, and argyiidina, the dry form, was taken 

 in January, in the valley of the Khoonah Khong, Eastern Manipur " (Ann. N. H. 

 1885, 340). Col. C. H. E. Adamson says, "I have caught this butterfly not 

 uncommonly in Upper Burma, but only a single specimen in Lower Burma. The 

 upper side varies in colour from shining white to a rich cream colour; the black 

 markings also vary considerably in intensity " (List, p. 44). Dr. N. Manders found 

 it " common in the Shan States at 8,000 feet elevation " (Tr. Ent. Soc. 1890, 

 584). 



We possess specimens of the wet and dry form from Sikkim, Bhotan, N. E. 

 Bengal, the Khasias, and Manipur ; also the types of jpseiidolaluge, and both sexes 

 of the dry form from the Karen Hills.
