I. satwa, de Niceville, J. A. S. B., 1883, p. 86. 



" Male. Upperside, rich dark brown. Forewing with two small 

 subapical spots, the lower one twice the size of the upper a rounded spot 

 at the lower outer end of the cell, two similar spots at the base of the 

 median interspaces, the lower one twice the size of the upper, all semi- 

 transparent diaphanous ochreous-white. A small ochreous spot above the 

 submedian nervure touching its middle. Hindwing with the middle of the 

 disc clothed with long greenish-ochreous hairs. Cilia cinereous. 



Underside also dark brown but the apex of the forewing and the outer 

 margin of the hindwing broadly washed with purple. Forewing with the 

 spots as above but lacking the one placed against the submedian nervure ; 

 the costa to beyond the middle of the wing bears a narrow bright yellow 

 streak widest at its end. 



Hindwing with the basal two-thirds also bright yellow, the outer 

 margin of this yellow area very irregular. A small round brown spot 

 near the middle of the cell another above it and one beyond. No second- 

 dary sexual characters. Body brown yellow below ; antennae brown above 

 obscurely annulated with yellow below, club brown. 



Female differs only from the male in being larger, the wings broader, 

 and the apex of the forewing less acute. There is a second minute spot 

 above the large one in the cell of the forewing. 



This is a fairly common species at low elevation below Darjeeling. 



Expanse: #1-3 to 1-4 9 1-55 inches." (de Niceville, I. c.) 



Recorded from Kumaon (Doherty) ; Orissa (Taylor) ; Sikkim (Elwes), 

 and I obtained two specimens in the Yaw district, Upper Burmah, in 

 March, 1890.
