244 PIERIDJE. 



outwards along the posterior half of the wing ; dorsum broadly 

 pale yellow; terminal border broadly black, broadest in the middle, 

 its inner margin crenulate ; discocellular spot large, consisting of 

 a small patch on which the ground-colour is paler and brighter 

 and that encloses two somewhat obscure dusky rings, the upper 

 one minute. Cilia of both fore and hind wings broadly salmon- 

 pink. Underside : light orange-yellow, the costal margin narrowly, 

 terminal fourth of the fore wing and the whole surface of the 

 hind wing overlaid with pale dull green ; the costa, termen and 

 dorsum, with the cilia of both fore and hind wings, salmon-pink. 

 Fore wing : discocellular spot as on the upperside but centred 

 with silvery white ; a postdiscal transverse Aeries of black spots, 

 obsolescent and curved inwards anteriorly, conspicuous and 

 increasing in size posteriorly. Hind wing : a discocellular double 

 spot conspicuous silvery and circled by a diffuse salmon-pink 

 ring, followed by a very obscure, almost obsolete, transverse, post- 

 discal series of pinkish spots. Antennae, head and thorax 

 anteriorly salmon-pink, club of antennae darkening to brown ; 

 thorax and abdomen dusky greenish black ; beneath : palpi, thorax 

 and abdomen yellow. Sex-mark, a patch of thickly set light 

 yellow scales at base of interspace 7 on the upperside of the hind 

 wing. $ . Differs from the d as follows : Upperside: the irroration 

 of black scales at the base of the wings more extensive, especially 

 on the hind wing ; the black on the subterminal margins broader, 

 its inner edge on both fore and hind wings more irregular and 

 somewhat diffuse ; on the fore wing the black is transversely 

 traversed by a series of bright yellow spots, the anterior four 

 small, obliquely placed, the posterior one large; on the hind wing 

 the discocellular patch is without the central dark rings con- 

 spicuous in the c? , and there is an obscure postdiscal curved 

 transverse series of yellow spots bordering the black on the 

 terminal margin. Underside : precisely similar to that of the <3 . 

 Antennae, head, thorax and abdomen on the upperside iis in the 

 3 ; beneath : the palpi and thorax more or less salmon-pink.
