 from Kasauli, N.W. Himalayas, Nepal ; Sikkim ; Bhotan ; Khasia Hills (Swinhoe) ; 

 Karen Hills, Burma ; and W. China. In the British Museum are examples from 

 the Kali Valley, Kumaou ; Landoor ; Sikkim and Bhotan, taken in March and April

 numerous examples from the Khasia Hills. Mr. L, de Niceville records it as " the 

 widest spread species of the genus and the most abundant in individuals where 

 met with. It occurs in India throughout the Himalayas and Assam to Upper 

 Tenasserim" {I.e. 241). "Fairly common, in the W. Himalayas, in the beds of 

 streams during the summer and autumn " {id. lud. Agriculturist, 1880). The Rev. 

 J. H. Hocking found the larva feeding on Nettle, in August, at 6200 feet elevation, 

 in the Kangra Hills. Mr. P. W. Mackinnon says " it occurs somewhat commonly 

 at Masuri and in the interior from April to October. The larva feeding on 

 Dehregeasia bicolor, N.O. Urticaceje, and is gi-egarious " (J. Bombay N. H. Soc, 

 1898, 376). Mr. W. Doherty saj^s it is " found, commonly, in low country and river 

 valleys in Kumaon, as far up as the Dhoaj, 6500 feet elevation. I have also taken 

 it in the Eastern Ghats of the Indian Peninsula, in the districts of Ganjam and 

 Vizagapatam" (J. A. S. Bengal, 1866,122). It is "common in Sikkim, up to 

 about 6000 feet elevation, all through the warm months. The larva feeding on 

 Girardinia heterophylla " (L, de Niceville, Sikkim Gaz. 1894, 145), Col. C. H. E. 

 Adamson says it is " fairly common in Lower Burma, but is not common in Upper 

 Burma, though on two successive days I took about a dozen at one spot near 

 Sayaing, in January (List Burm. Butt. 1897, 25). Mr. W. L. Distant records it
