orange-red patch on the posterior terminal half of the wing between the 

 dorsum and vein 7 ; this patch does not extend quite to the termen but 

 leaves a narrow edging of the black ground-colour which is produced 

 inwards in short conical projections in interspaces 2 to 5. Cilia oi both fore 

 and hind wings chequered with black and white alternately. Under- 

 side : silvery white. Fore wing : a short line inider the costal vein from 

 base ; a quadrate spot on the discocellulars ; a broad, transverse, discal 

 band and the terminal third of the wing : jet-black ; the discal baud is irre- 

 gular, dislocated on vein 3, the posterior portion shifted inwards and 

 joined on to the black area on the posterior terminal third of the wing by 

 projections of black on the dorsum, along veins 3 and between venis 4 and 

 ~> ; the black area on terminal third of the wing encloses a transverse, post- 

 discal series of small, round and a subterminal, transversely-linear series 

 of spots of the white ground-colour. Hind wing : one spot at base, a 

 subbasal transverse series of three spots; a medial, similar series 

 of four somewhat elongate spots and a transverse, short, postdiscal 

 bar between veins 4 and 6, and, often, some postmedial, further dots 

 jet-black ; terminal third of the wing above vein 7 jet-black, below that 

 vein deep orange-red, the whole area (both the black and the red) medially 

 traversed by a transverse curved series of round spots of the white ground 

 colour and margined outwardly by a series of transverse, verj^ short and 

 very slender lines of the same in the interspaces : anticiliary line black. 

 Cilia of both fore and hind wings chequered as on the upperside ; a short 

 lilamentous tail at ajiex of vein 2 black, tipped white. Antenmy, head 

 thorax and abdomen black, shaft of the antennse ringed with white ; 

 beneath : palpi, thorax and abdomen white. Expanse ; Male and female, 

 .33-42 mm. 



Effff. — Turban-shaped, covered on the sides with rough, convex, roundish 

 excrescences, each one with a depression in the middle and each connected 

 with the immediately surrounding ones by fine low ridges ; the top of the 

 egg is nearly fiat and is finely reticulated except in a small, central area 

 which is slightly raised and smooth. The colour is light enamel-green, the . 

 ridges and excrescences pure white. B : O. 8 mm. 



Larva.— The shape is that of Nacaduba more or less, but is somewhat 

 llattened. It is broadest at segments 8 and 9, although nearly of the same 

 breadth from 3 to 10 ; highest at segment 7 ; anal segments flattened, anal 

 segment itself rather square at extremity ; each segment has a lateral de- 

 pression parallel to its margin, the yrd and 4th being dented also in the 

 dorsal line more or less circularly, giving these two segments a depressed 

 appearance in that region. Surface covered with sparsely disposed, short, 

 light hairs wliich are longer round the body margin. Spiracles conspicuous 

 being rather large, quite circular and deep black. Colour shining trans- 

 lucent-looking yellowish white, nearly transparent on the margins of the 

 body ; ventrum the same colour. L : about 10 mm ; B : 3 mm. 



fupa — Rather narrow but, on the whole, normal and like the Nacaduha 

 group. Head hidden from above ; segment 2 rounded in front ; thorax is 

 convex and slightly compressed ; the constriction at segment 4 is slight 

 dorsally and still less laterally ; transverse section of abdomen nearly 

 circular, slightly depressed ventrally ; anal end rounded ; broadest at 

 segments 7 and 8 ; highest at thorax. Surface of the body clothed with 

 comprativly long, light-coloured, diffuse, erect, translucent hairs all over 

 except on the wing-cases. Spiracles of segment 2 are indicated by 

 longly oval, raised, light coloured, low risings ; the others are longly oval, 

 light in colour — the colour of the body. The colour of the pupa is 

 a light cream with two black spots at each shoulder, another, dorsal, 

 at the hinder margin of segment 2, a lateral black spot near the
