(MS. Notes) remarks that Philoxemis, Dasarada, and Ravana fly together at Nalni 

 Tal, in September. Mr. H. J. Elwes possesses specimens from Hazara in the 

 extreme N. W. Himahaya " (Tr. Ent. Soc. 1888, 426). A male taken at Murree in 

 August, and a male from Dalhousie taken in May, are in the British Museum. General 

 G, Ramsay obtained numerous specimens in Nepal, of which we possess examples of 

 both sexes. Mr. Elwes records it as " common in Sikkim at the same elevations 

 and in the same months as Dasarada" (Tr. Ent. Soc. 1888, 426). Mr. G. C. 

 Dudgeon took it at Buxa, Bhotan. Col. C. Swinhoe has received many specimens 

 from the Khasia and Jaintia Hills. Mr. Ossian Limborg obtained it on the roads 

 from " Moulmein to Meetan, Upper Tenasserim, and from ]\Ioolait to Moolat at 4500 

 feet elevation, in December " (1*. Z. S. 1878, 840). Dr. N. Manders found it 

 "abundant in the Shan States, Burmah, and widely distributed" (Tr. Eat. Soc. 

 1890, 535). We possess both sexes from the Upper Mekong, Shan States, taken by 

 Mr. J. Roberts, C.E. Mr. H. J. Elwes records a "single male from Ponkesai, 

 Tavoy, Tenasserim" (J. A. S. Beng. 1886, 435). It also occurs in Siam, Tonkin, 

 Western China, and the Malay Peninsula.
