Adamson says “ males are very common throughout Burma. From April to October 
they frequent beds of streams, flyiug up and down the same with great rapidity 55 
(List, of Burm. Butt. 1897, 49). Lieut. E. Y. Watson found it “ common at 
Beeling ” (J. Bombay, N. H. S. 1888, 26). “A single specimen was taken at Tilin 
in February, and another at Choungkwa in May” (id. lx. 1891, 54). It was found 
“not uncommon at the foot of the X. Chin Hills, in May” (id. lx. 1897, 672). 
Mr. de Niceville also records it from “ Chin Lushai, March ; and Lamtok in April ” 
(lx. 1890, 6). Mr. H. J. Elwes records “ numerous males, but no females, from 
Ponsekai and the Hills, Tavoy ” (J. As. Soc. Beng. 1886, 487). Mr. F. de Roepstorff 
obtained it at “Port Blair, S. Andamans ” (P, Z. S. 1877, 598, J. As. Soc. Beng. 
1880, 288).

Imago.—M ale. Hpperside black. Foreiving with four pale emerald-green cell- 
streaks and a small spot at its end, a smaller less-apparent streak also below base of 
the cell, a transverse inner-discal oblique macular band of eight spots, the upper 
three being small, the lower five increasing posteriorly in size and length, followed 
by a submarginal row of small mostly quadrate spots. Cilia black. Hindwing with 
a pale emerald-green transverse subbasal posteriorly-decreasing band, which is 
broadly intersected by black-bordered veins, the two costal portions being white; 
sometimes there is also a dot or a very small contiguous spot in the upper median 
interspace ; beyond is a submarginal row of mostly-quadrate spots; abdominal 
margin broadly white, the scent-organ absent. Cilial lunules slenderly white. 
Underside sepia-brown, with similar markings, as on upperside, of a bright nacreous 
tint, the cell-streaks and submarginal spots being much larger. Foreiving with the
