PAPILIO. 51 



outer three-fourths of the wing grey touched with ochraceous, but 

 generally narrower than the blue on the upperside ; the inner 

 margin of the grey area crosses the wing beyond the cell ; the post- 

 discal and subterininal black spots as on the upperside. In some 

 specimens this grey area is greatly restricted, its inner margin 

 crossing the wing well beyond the apex of the cell ; the subtermiual 

 spots merged completely with the terminal spots and form a 

 comparatively broad terminal black band. Antennae, head, thorax 

 and abdomen blackish brown. 2 very similar but the inte.r- 

 nervular streaks on the fore wing paler, extended into the cell 

 both on the upper and undersides. Hind wing : the pale blue 

 area on the upperside and the corresponding grey area on the 

 underside paler. In some specimens there is a diffuse short 

 crimson streak at the base of the cell of the fore wing on the 

 upperside. 



Rep. <S 2 131-156 mm. (5-48-6-14"). 



Hab. Sikhim ; Lower Bengal ; Central and Southern India. 



Larva and pupa. "We noticed this butterfly at Matheran in 

 the month of March laying its eggs on a lime tree in the garden. 

 In Karwar we reared a great many in September and October on 

 a common w ild orange (Atalantia, sp. ?). Another favourite food 

 appears to be Garcinia xanihochymus. In form, colour and 

 markings the larva is very similar to that of the last two 

 (P. demoleus and P. polytes\ but the enlargement of the 4th and 

 5th segments is much exaggerated, especially after the last moult. 

 In the pupa the head-case and its two projecting points are more 

 elongated." (Davidson &f Aitken.) 



Race parinda, Moore. I have, following Eothschild, regarded 

 this form as a distinguishable race, but the males are very similar 

 to the typical form, though the females can always be descrimi- 

 nated. It might well stand as polymnestor with a dimorphic 2 iu 

 Ceylon. 



cJ . Differs in the broader postdiscal blue band on the uppei'- 

 side of the fore wing and the greater extent of the blue area on 

 the hind wing. 2 has the same band on the fore wing and the 

 blue area on the hind wing much paler and invariably tinged 

 (sometimes very strongly so) with yellow. On the underside 

 both the band on the fore wing and the outer area on the hind 

 wing are generally ochraceous-yellow without a touch of blue ; 

 the former much broader than in the typical form. 



Rvp. J 2 130-156 mm. (5-16-6-14"). 



Hab. Confined so far as is known to Ceylon. 



Larva. " Smooth, glossy green ; with a whitish lower lateral 

 band from 6th to anal segment, a broad similar coloured band 

 obliquely ascending the 8th and 9th and a similar band on the 

 10th segment ; anterior shield edged with white, its posterior 

 dorsal end bordered by a transverse blackish-marked crest, a 

 similar crest also across the 4th segment ending on each side in 

 a large ocollated spot. Feeds on Citrus decumana" (Moore.) 



Pupa. " Green or olive-brown." (Moore.}
