black spots less conspicuous than in ^, but similar in number and 

 arrangement (except that the spot nearest base is wanting) ; beyond 

 black costal stripe a large, very conspicuoiLS^ hroad, lohite patch, divided 

 into six portions by crossing nervules, the two sections next costa being 

 very small and narrow, the lower edge of the white touching second 

 median nervule ; apes more broadly and darkly clouded with blackish. 

 Hind-wing : paler, more ochreous than fore-wing ; marked as in ^, but 

 radiations of black on nervules from hind- marginal border usually 

 broader and more strongly marked, making the inter-nervular rays of 

 the ground-colour narrower and more acute. Under side, — Fore-iving : 

 paler than on upper side ; white patch less conspicuous ; spots as in ^ ; 

 nervules clouded with blackish near hind-margin ; inter-nervular rays 

 dull yellow-ochreous. Hind-iving : dull yellovnsh-ivhite ; black spots 

 as in ^ ; interspersed pale-reddish marks very faint or wanting ; spots 

 in hind-marginal border yellower than in ^ ; inter-nervular marks im- 

 mediately before border ill-defined, dull yellow-ochreous, usually irrorated 

 thinly with fuscous on their inner side, 



Var. ^. — All the black markings smaller and less dark than in type 

 form, especially the hind-marginal borders and the oblique bar of fore- 

 wing. Hind-wing : the second, third, and fifth spots of median trans- 

 verse row wanting.

Larva. — " Back yellowish-brown, with transverse blackish streaks ; 

 dorsal stripe and sides purplish-black, the latter much lighter about 

 spiracles ; lateral inflation edged with light-yellow, almost white. Under 

 SIDE. — Light bluish-green.; ventral claspers and pro-legs yellowish. 

 Head black and polished, larger than second segment ; mouth and 

 bifid mark on forehead white ; in some specimens also two small 

 white streaks on summit of head. Spines steely-black, largest on 

 third, fourth, and fifth segments ; a suffusion of white at the base of all 

 excepting those on the second, third, fourth, and fifth segments. About 

 i-incli in length." — H. C. Harford, in litt. 



Of the younger larvas Mr. Harford remarks that they have very 

 few black markings, and no dorsal or lateral stripes, but that these 

 gradually appear and grow more distinct with the development of the 

 insect. He further observes that the larvae feed on a tree in great 

 numbers together, and that, when the bough upon which they are so 

 congregated is shaken with any violence, they lower themselves to the 

 ground by a silken thread, and there, lying still, are with great difl[i- 

 culty to be detected among the dead leaves and debris. 



Pupa. — Pale-grey anteriorly ; the outlines of the head and limbs 

 and the nervures of wings finely defined with black. Abdominal region 

 of a browner tint ; spots of the usual rows ochreous-yellow in black 

 rings, separate from each other. 



Described from a drawing of Mr. Harford's, giving a lateral 

 view.
