DrsTEiruTioN. — We possess a male from Nepal, taken by the late Gen. G. 

 Ramsay. Mr. H. J. Elwes says it is " not uncommon in the low valleys of Sikkim, 

 and is often seen flying up and down the course of the rivers, in company with 

 Hclenus and many other species, from April on till October" (Tr. Eat. Soc. 1888, 

 429). Col. C. Swinhoe records it " common in the Khasia Hills " (Tr. Ent. Soc. 

 1893, 312). Mr. J. Wood-Mason obtained three males at Irangmara, C'achar, from 

 July 25th to August 6th " (J. A. S. Bengal, 18SG, 375). Col. C. H. E. Adamsou 

 says it is "widely spread throughout Burma, except in the hot plains" (List, 1897, 

 47). Capt. E. Y. Watson found it in the " Chin Hills, occurring rarely, in company 

 with Helentis, during the di-y season, January to June" (J. Bombay N. H. S. 1897, 

 671). Mr. Ehves records " two males from Ponsekai, Tavoy " (J. A. S. Beng. 188G, 

 436). Dr. N. Manders found it "not so common, in the Sh;in States, as Relenub-, 

 but occurring in the same localities" (Tr. Eut. Soc. 1890, 536).
