turns outwards and is again extended inwards in a rounded curve in 

 interspace 1, finally it is sloped obliquely outwards and terminates 

 on the dorsal margin jnst before apex of tornal angle; three, 

 rarely four, yellowish spots placed in an outward curve preapically 

 in the black area. Hind wing : pale yellow, the terminal margin 

 broadly black, this colour extended triangularly up the veins for a 

 short distance ; base and interspaces 1 and 2 irrorated with black 

 scales. Underside, fore wing : as on the upperside but the irrora- 

 tion of black scales at base and in cell replaced by pale yellow ; 

 apex of wing from beyond middle of costa in a curve to apex of 

 vein 3, thickly overlaid with rich chrome-yellow. Hind wing : rich 

 chrome-yellow, base greenish ; a postdiscal, broad, dark, slightly 

 curved band crosses from vein 2 to the costa near apex of wing. 

 Antennae black speckled with minute white dots ; head in front 

 and thorax with dusky greyish-green hairs ; abdomen blackish ; 

 beneath : thorax yellow, abdomen white. 



Dry-season brood. c? . Upper and under sides : similar to those 

 of wet-season specimens, but the irro ration of black scales much 

 sparser on the upperside ; on the underside the apex of the fore 

 wing and whole surface of the hind wing dullochraceous, not pale 

 clear yellow. . Upperside : similar to that of the wet-season 

 form, but the black area on the fore wing somewhat circumscribed. 

 Hind wing: white, the black terminal border narrower and decreas- 

 ing in width posteriorly. Underside : apex of fore wing and the 

 whole surface of hind wing a beautiful nacreous bluish white. 

 Antennae, head, thorax and abdomen as in the wet-season form.

 from the Malay Peninsula, Siam and Java.

c? . Upperside : creamy-white. Fore wing : a very slight 

 irroration of black scales at base, along the costal margin, at apex 

 of wing and for a very short distance down the termen ; a round 

 black postdiscal spot in interspace 3, conspicuous in some specimens 

 (wet-season form ?), scarcely perceptible in others (dry-season 

 form ?) ; cilia anteriorly dusky black, posteriorly white. Hind 

 wing : uniform ; cilia yellowish posteriorly. Underside : fore wing 

 white, basal half of cell sulphur- yellow ; costa narrowly and apex 

 of wing ochraceous or butter-yellow ; the round black postdiscal 

 spot in interspace 3 more clearly defined. Hind wing : uniform 

 butter-yellow. Antenna3 brown speckled with white ; hairs on 

 head and thorax anteriorly dusky greenish-yellow, on thorax 

 posteriorly bluish, scaling of abdomen white; beneath : head and 

 thorax very pale yellow, abdomen white. $ . In both seasonal
