DiSTEiBUT[ON. — Baron von Hiigel's specimens are recorded as having been taken 

 in the "neighbourhood of Masuri " (Kollar, I.e. p. 408). Capt. A. M. Lang, in his 

 MS. Notes, dated 1868, writes that he took " Belladonna at Masuri, at 7,000 feet 

 elevation, in April, May, and Juue." Mr. W. Doherty obtained it at " Sargii, Kali, 

 and Gori Valleys, 2,000 to 5,000 feet elevation, in Kumaon " (Journ. As. Soc. 

 Bengal, 1886, 135). Mr. P. W. Mackinnon writes : "Belladonna is exceedingly 

 common on the Nag Tiba range, north of Masuri, at about 8,000 feet elevation, from 

 April to July. In Masuri it is usually a rare insect, but in May, 1888, May, 1894, 

 and May, 1895, it was very plentiful. In a few minutes, specimens of all shades of 

 colour, from very dark, almost black examples (typical i)'t;/^(i(?OH;irt), through yellowish- 

 white ones (typical Sanaca) to the palest form {fiavalba) could be caught. It may 

 be noted here that the two last-named forms are strictly confined to the "Western 

 Himalayas. Mrs. Robson found the larva feeding on the leaves of Loranthus 

 longiflorus, and Mr. Mackinnon found it on L. vestitns, N. 0. Loranthaceas. Males 

 are more often caught than females, and may usually be easily distinguished from 

 the females by the bright yellow inner margin of the hiudwiug on the upperside, 

 which coloration is absent in the opposite sex " (Journ. Bombay N. H. Soc. 

 1898, 585). Col. Svvinhoe (Tr. Eat. Soc. 1893) does not record it from the Khasia 

 Hills. There are specimens in the British Museum of both sexes from Kulu, Kali 

 Valley, Nepal, Sikkim, and from Moolayet, Burma, taken by Col. C. T. Bingham. 

 In Mr. J. H. Leech's Collection are specimens from Sultanpur, Kulu, taken by 

 Capt. G. Young. We possess both sexes from the W. Himalayas, Nepal, Sikkim, 

 Bhotan, Moulmein, and the Karen Hills, Burma. Mr. W. Rothschild possesses it 

 from Haundraw, Burma, and the N. Shan States.
