fonuiiiir hri-ht but slightly interrupted bamls j)osteriorly on 

 the segments; crests light greyish oclueous ; sides of base 

 bhu-kish ; underside white. Fore and middle legs largely 

 bhickened, the fennir and part of tibia remaining white on 

 outer sides; iiind leg whiter, but irrorated or clouded with 

 grey. 



Fore icing \)X02ii\ ', SO' wanting (sport?); white, irrorated 

 with olive-grey and very sparsely with black, the proximal 

 and distid areas also with bright oclireous, the veins in these 

 areas broadly, in the median area very slenderly, bright 

 oclireous; an ill-detined blackish band or shade close to base, 

 not reaching costa ; antemedian line thick, black, at little 

 b.'yond one-fourth, very gently curved, at M and SM^ very 

 slightly dentate inwards ; median area more olivaceous 

 costally and with long, not very strong, olive-grey cell-mark ; 

 po^tmedian line black, from beyond two-thirds costa to about 

 ihrec-titths hind margin, strongly dentate outwards on most 

 of the veins, feebly so on S]\P, nearest the termen at R^ and 

 the n)edians, retracted behind liP ; subterminal white line 

 distinct between M^ and hind margin, running obliquely 

 towards tornus, very faint in the rest of its course ; some 

 ill-defined whitish dots to termen. 



Flind icing with subbasal shade slight, antemedian line 

 wanting, no oclireous proximal area ; hairs of median area 

 bright oclueous; postmedian line tiner than on fore wing, 

 otherwise simihxr ; distal area nearly as on fore wing. 



Un'ierside dirty white, with rather broad black borders 

 containing large white terminal sj)Ots, so that the black only 

 runs to the termen between the radials, around M' (in both 

 these places more narrowly on hind wing), and at tornus ; 

 base, especially at costa, bright yellow ; fore wing with a 

 lather large dark discal mark.

 from Tananarive, recently acquired by Mr. Joicey, is some-
