DiSTKiBDTioN.— Capt. A. ]\I. Lang {Epist. ]^ov. 13, 1869) records it from Masuri, 

 N. W. Himalaya. Mr. P. W. Mackiunon obtained " a single male in Masuri in April, 

 and also a few in Tehri Garhwal in May" (J. Bombay N. H. Soc. 1898, 592). Mr. 

 AV. Rothschild records it from " Kumaon, taken by Dr. Pilcher in July " (Nov. Zool. 

 ii. 258): Mr. Wood-Mason obtained " a male at Irangmara, Cachar, in August, and a 

 female on Neraotha Peak, Cachar, in September" (J. A. S. Beng. 1886, 375). We 

 possess specimens from Nepal, Darjiling, and Buxa, Bhotan. Mr. H. J. Elwes says, 

 " this species is not uncommon in Sikkim at 2000 to 3000 feet elevation, from April to 

 November " (Tr. Ent. Soc. 1888, 423). Mr. L. de Niceville records it " as far rarer 

 than Astorion in Sikkim, and found up to 3000 feet from April to November (Sikk. 

 Gaz. 1894, 170). Col. C. H. E. Adamson took "a male and female on the Naafand 

 Mayu road in Arakan, in October" (List. Burm. Butt. 1897, 46). Dr. N. IManders 

 found it " not uncommon in the Shan States. It is fond of the deep shade of forest 

 trees overhanging streams, under which it flies with a slow graceful flight " (Tr. 

 Eut. Soc. 1890, 535). It is also recorded from Tonkin (Oberthiir, Et. Ent. 

 1893, 1).
