that shows plainly through ; costal margin of fore wing irrorated 

 densely on basal half, more sparingly on apical half, with black 

 scales ; terminal margins of both fore and hind wings edged with 

 black, this colour produced triangularly inwards along the veins 

 for a short distance ; veins of both wings white, subcostal vein 

 and veins above vein 6 on fore wing black. Underside, fore wing : 

 white ; extreme base of costa irrorated with black scales, some- 

 times condensed into a broad edging along the costal margin, which 

 is widened at the apex and continued along the terminal margin in 

 a gradually narrowing border to the tornus, the terminal edging 

 inwardly produced along the veins as on the upperside ; a yellow 

 or white oval spot superposed on the black area at the apex in 

 interspace 6. Hind wing : sulphur-yellow ; veins concolorous ; 

 terminal margin with a black edging as on the upperside but 

 much broader, though not so prominently produced inwards along 

 the veins. Antennae black, sparingly spotted with minute white 

 dots ; head, thorax and abdomen white with a bluish tinge. 



$ . Upperside : dusky blackish brown, variegated more or less with 

 white on the fore wing, in short somewhat broad streaks in inter- 

 spaces 1, 2, 4 and 5 ; these streaks very variable in width and 

 length. Hind wing on the basal half and along the dorsum broadly 

 white ; the extent of the white is very variable and very ill- 

 defined, shading imperceptibly into the dusky brown. Underside : 

 fore wing similar, the white streaks much broader and longer ; 

 an additional dusky-white longitudinal streak along middle of the 

 cell ; base of wing dusted with yellow scales ; apex with a large 

 diffuse purplish patch. Hind wing: basal two-thirds pale sulphur- 

 yellow; apical third dusky brownish black, the margins of the two 

 colours fairly sharply defined, veins crossing the disc black. An- 

 tennae as in the d 1 ; head, thorax and abdomen above with greenish 

 pubescence ; beneath white. 



Dry-season brood. <$ $ . Similar to the wet-season form but 

 smaller. In the <$ the black edging to the wings both on the 

 upper and under sides is narrower, often very markedly so. In 

 the $ the differences are more conspicuous in the extreme forms. 

 Specimens captured in the height of the hot weather or in specially 

 dry localities resemble the <5 of the wet-season form, except that 

 the irroration of black scales along the costal margin in the latter 

 is replaced by a broad continuous streak, widened at apex and 

 continued in a similar manner as in the J , along the terminal 

 margin to the tornus, the inward prolongations of the black colour 

 along the veins more marked. On the underside the dry-season 



$ very closely resembles the wet-season <$ , the only 'marked 

 difference is the absence of the elongate oval spot in interspace 

 in the fore wing. This form is the Appias Jiippoides, var. epiccena, 

 Swinhoe. Between it and the dark wet-season form of the 

 many intermediate individual specimens can be found in almost 

 every large collection.
