d 2 • Closely allied to and resembling P. gambrisius, from 

 which it differs as follows : — Upperside : ground-colour a bright 

 bronze-green, the subhyaline white spots near apex of cell in the 

 fore wing more opaque, the broad discal band of large white spots 

 proportionately more basal further from the termen and very 

 irregular, the spots, especially towards the hinder part of the wing, 

 more widely separated, the spot in interspace 5 more acutely tri- 

 angular and smaller, the tw T o spots above shifted obliquely inwards 

 towards the costa, making the outer margin of the discal band 

 angulate at interspaces 5 and 6. Hind wing : the postdiscal and sub- 

 terminal markings broader and more diffuse than in P. gambrisius, 

 giving a dark shade to the whole of the apical half of the wing. 

 Underside pale greenish grey. Pore wing : the spots and markings 

 except the basal black streaks as on the upperside, the ground- 

 colour fading to an ashy grey towards the terminal margin. 

 Hind wing similar to the underside of hind wing of P. gambrisius, 

 but the discal transverse sinuous black line very broken and 

 incomplete, the postdiscal, subterminal and terminal black mark- 

 ings somewhat better defined. Antennae black ; head, thorax and 

 abdomen bronze green, barred with black above ; beneath whitish. 



Exp. 6 2 112-120 mm. (4-475"). 



Bab. S. India from Canara to Travancore. 



Larva. Cylindrical ; head and anal segment with short simple 

 spines ; segments 3 to 12 with longer branched spines, reddish 

 brown in colour, those on 3 and 4 comparatively very long. 

 Colour pale green, with yellowish-white lateral stripes one on each 

 side. 



Pupa " brown, boat-shaped." {After Davidson ty AitJcen.) 



Pace cyaneus, Moore, differs from P. virens on the upperside in 

 the ground-colour being of a beautiful pale greyish blue, the discal 

 band of spots on the fore wing proportionately closer to the 

 termen, and the spots, especially towards the hinder part of the 

 wing, even more widely separate. In the hind wing the postdiscal 

 paired streaks in the interspaces do not generally coalesce, but 

 are separate ; the subterminal black spots are more lunular than 

 triangular in shape, and the terminal black band more sinuous. 

 Underside pale greyish green, the markings similar to the markings 

 in the typical form. 



Exp. 6 2 HO-126 mm. (397-4-97").

Larva. " Cylindrical ; pale yellowish purplish brown, darker 

 beneath, with dark brown longitudinal dorsal lines and transverse 

 white-dotted segmental lines ; head and legs dark brown, head 

 and anal segment spined ; other segments slightly hairy ; third 

 and twelfth segments armed with erect rather long dark purplish
