Habitat. —W. Himalayas; Nepal; Sikkim; Bhotan; Burma; Shan States. 
Distribution. —Baron von Hiigel’s specimens are recorded as having* been taken 
in the 44 neighbourhood of Masuri ” (Kollar, l.c. p. 408). Capt. A. M. Lang, in his 
MS. Notes, dated 1868, writes that he took 44 Belladonna at Masuri, at 7,000 feet 
elevation, in April, May, and June.” Mr. W. Doherty obtained it at 44 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 : 44 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 Belladonna), through yellowish- 
white ones (typical Sanaca) to the palest form ( flavalba ) could be caught. It may 
be noted here that the two last-named forms are strictly confined to the Western 
Himalayas. Mrs. Hobson found the larva feeding on the leaves of LorantJms 
loncjifiorus, and Mr. Mackinnon found it on L. vestitus , N. O. Loranthacem. Males 
are more often caught than females, and may usually be easily distinguished from 
the females by the bright yellow inner margin of the hind wing on the upperside, 
which coloration is absent in the opposite sex ” (Journ. Bombay N. H. Soc. 
1898, 585). Col. Swinhoe (Tr. Ent. 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. Hothschild possesses it 
from Haundraw, Burma, and the N. Shan States.
