APOKIA. PIEEIS. 167 



the posterior one in the first median interspace (interspace 2) is 

 the largest and occupies the base of the interspace ; the outer 

 margin bears, one in each interspace at its middle, a series of 

 somewhat diffused white spots. Hind wing has the veins on the 

 basal half of the wing defined with white, broadly margined on 

 both sides with black ; the discoidal cell almost entirely creamy- 

 white ; there is a very narrow costal and a wide subcostal streak, 

 then five spots one in each interspace beyond the cell, that in 

 the second median interspace (interspace 3) the smallest ; two 

 elongated streaks in the submediau interspace (interspace 1), the 

 inner one almost reaching to the margin of the wing, the outer 

 one reaching to about halfway between the base of the wing and 

 the margin ; two basal white streaks occupying the whole of the 

 interspaces divided by the internal nervure (vein 1 a) ; marginal 

 diffused spots as in the fore wing, but each spot divided into two 

 by the black internervular fold. Underside : differs from the 

 upperside only in having on the outer margin from the costa to 

 the second median nervule (vein 3) a decreasing series of dupli- 

 cated white streaks, one pair in each interspace, a small white spot 

 in the two following interspaces. Hind wing has at the extreme 

 base of the wing within the precostal nervure the usual bright 

 yellow patch characteristic of the genus ; all the creamy-white 

 markings of the upperside are pale yellow ; the markings differ 

 from those on the upperside by the presence of a pair of elongated 

 wedge-shaped pale yellow streaks in each interspace, each streak 

 has its apex pointed, its base (which is placed on the outer 

 margin) broad. Cilia of both wings on both sides black. $ 

 differs from the tf only in being somewhat paler throughout."
