There are two forms of this which may be distinct, but I have a 

 series of them only from Sikkim. The one I take to be the typical 

 form is of a greenish shade, but not constant, some specimens being 

 lighter and some darker ; and this I have from the N.W. Himalaya, 

 Sikkim, the Khasias, Nilgiri Hills, and Japan, and Moupin in East 

 Tibet. Another is metallic bluish on the thorax and base of both 

 wings, sometimes with a tinge of green, and the rest of the wings, 

 except anal area and fringe, black. This I have from Sikkim and 

 the Naga Hills. These differences may be sexual; but it is very 

 difficult to be sure of the sex in this genus.
