DiSTEiBUTiON. — " This species is not uncommon in both sexes, in Sikkim, at low 

 elevations, and is found up to 7,000 feet. It occurs from April to December" (H. 

 J. Elwes, Tr. Ent. Soc. 1882, 422). L. de Niceville also records it as " common in 

 Sikkim from April to December, and from the level of the Terai up to 7,000 feet 

 elevation." (Sikk. Gaz. 1894, 170). Col. C. Swinhoe records it from the Khasia 

 Hills. (Tr. Ent. Soc. 1893, 312). Mr. J. Wood-Mason took "four males and five 

 females at Irangmara, Cachar, in May and August ; the female emitting a stong and 

 disgustingly rank musky odour" (de Niceville, J. A. S. Bang. 1886, 875). Col. C. H, 

 E. Adamson obtained "a male at Bhamo, Burma, in April, and females in Arakan 

 also in April" (List Burra. Butt. 1897, 46). Dr. J. Anderson obtained "females 

 only at Thaing, King Island, Mergui Ai'chipelago, in January and Februai'y " (J. 

 Linn. S. Zool. 1886, 51). We possess specimens from Bhotan, taken in April by 

 Mr. G. C. Dudgeon, Shillong, Assam, and Khasia Hills ; and a female from 

 Mergfui.
