DiSTEiBUTTOX. — " Occurs commonly in deep forest in Sikkim in the summer, and 

 appears to be single-brooded. Mr. S. E. Peal has taken it at Sibsagar, and Mr. J. L. 

 Sherwill at Jorehat, in Assam. It also occurs in Silhet, Munipur, the Dafla and Naga 

 Hills" (de Niceville, I.e. 145). Mr. J. Wood-Mason obtained "numerous specimens 

 in the forests near Silcuri, Cachar, in July and August, and one at the foot of the 

 North Cachar Hills in August " (J. A. S. Beng. 1886, 558). " It is not very rare 

 in Sikkim in May and June at 2UD0 to 4000 feet elevation " (H. J. Elwes, Tr. Ent. 

 Soc. 1888, 351). "Major J. F. M. Fawcett has taken it at Singla, Sikkim, at 2000 

 feet elevation in May, and Mr. G. C. Dudgeon in Daling at ]500 feet in May and 

 June commonly. It is single-brooded. I possess specimens from Upper Burma " 

 (de Niceville, Sikk. Gaz. 1894, 140). "It occurs in the Chin Hills very rarely, in 

 February" {id. Journ. Bombay N. H. Soc. 1899).
