by a siniiOTis, subterminal series of small, pale-green spots as on the fore- 

 wing. Underside; brown ish-fnlvous black; markings similar, larger, their 

 edges slightly diffuse and all of a silvery white, slightly tinted with pale 

 green. Hind wing, in addition, has a white, basal streak that extends 

 halfway down the dorsal margin ; another shorter, white subbasal streak 

 from costa to the subcostal vein coalescent with the white of the discal 

 band in the cell, the streak of ground-colour that lies between this subbasal 

 band and the discal band jet-black, interrupted, where it crosses vein 8, 

 iby a crimson bar ; finally, quadrate black spots near the apex of the ceil 

 and at bases of interspaces 1, 2, 3, all outwardly margined crimson. 

 Antennte, head, thorax and abdomen black ; beneath the palpi, thorax 

 and abdomen touched with white ; the abdomen with dingy white, lateral 

 line. The abdominal fold of the hind wing of the male is grey within with 

 a fringe of white hairs. — Expanse 76-90 mm. 



Larva. — The shape is similar to that of P. nomius though not so angular 

 looking. The head is round, green, generally retracted under segment '2. 

 Segment 2 is convex with a straight front margin with a small, black- 

 tipped conical, horny spine or tubercle dorsolaterally on the margin ; 

 segment 3 increasing in width backwards, rather long, convex, ascending 

 in dorsal line to segment 4 which forms the highest part of the body. 

 Segment 5 is equally high and the region about the common margin 

 of segment 4 and 5 is the broadest part of the body ; the larva decreases 

 in diameter thence backwards gradually, the transverse section always 

 circular flattened ventrally ; anal segment narrow, oblong, flattened 

 dorsally, produced beyond claspers and ending narrowly in two diverging, 

 not very long, more or less rigid points. Surface smooth, velvety, dull, 

 head and ventrum downy, with a short, sharp, conical, shiny black conical 

 spine laterally on segment 4. Spiracles oval, white, with a thin, black 

 border. Colour bright grass-green, the lateral spine on segment 4 

 •surrounded by a yellow * eye,' with a subspiracular white band from 

 segment 5 to anal end, the tail-points also white. The osmeteria are 

 lemon-yellow in colour. The larva is sometiti.es black or very deep brown 

 instead of green ; always black in its early stages with the tail-points pure 

 white ; the egg-larva spined as usual ; the segmental skin is always very 

 <lark green in colour. L : 38mm. ; B: 10mm. ; H. : 10mm. 



Pupa. — Of the same type as that of P. nomius. Head prominently convex 

 between the pear-shaped, bulging eyes ; each eye with a short, conical 

 anterior point, the front margin of pupa convex between them ; segment 2 

 inclined to longitudinal axis of pupa at an angle of 45°, pentagonal 

 more or less in shape, the longest side being the hinder margin, somewhat 

 ■convex ; thorax in the same plane of ascent as segment 2, perhaps slightly 

 steeper, to the base of the long, thick, apical process which runs out from 

 .apex at right angles to front slope at an angle of 30° to longitudinal axis
