THE BUTTERFLIES OF CEYLON 105 
It differs from the Indian P. helenus in having a complete 
series of seven sub-discal blue lunules on the under side of the 
hind wing, but the two in interspaces 3 and 4 are sometimes 
nearly obsolete. The number of red lunules visible on the 
upper surface of the hind wing varies from 1 to 5 in my 
specimens - 
It is only found where there is a fairly heavy rainfall. It 
is very plentiful in the jungles between Haputale and Ohiya 
(4,000 to 6,000 feet) and occasionally descends as low as 
Haldummulla, but it is very rarely seen below 3,000 feet 
in Uva. In wetter districts it is found at very low eleva- 
tions, and it has been taken at Kottawa, near Galle. It is 
common at Ratnapura, Madampe, and Deniyaya. 
The female seems to be very rarely captured. I have only 
one specimen, which I bred. It differs from the male in 
having the inter-nervular yellow streaks on the fore wing 
much more clearly marked, as they are formed by scales in 
the 9, and by hairsinthe g. It also differs in having the 
white patch on the lower wing the same size both above and 
below, in the ¢ this patch is much smaller on the under 
surface than on the upper. The males are fond of settling 
on wet patches on the roads or in the beds of streams. 
180. PAPILIO (ILIADES) POLYMNESTOR PARINDA, B., FE, 
Iliades parinda, M. Peculiar to Ceylon, but is a race of the 
Indian polymnestor, The male differs from folymnestor 
in the greater area of the blue on the upper side. The female 
differs in having the blue area tinged in spots, or sometimes 
even entirely replaced, by pale buff. The last form is by far 
the rarest. 
It is a most variable insect. In the male the width of the 
blue band on the fore wing varies greatly, and the post-discal 
spots on the hind wing may be large and conical, as in polym- 
nestor, or small and round. In the female these spots are 
sometimes very much reduced, and the two upper ones may 
be entirely obsolete. 
It is very common at Haldummulla, especially during the 
south-west monsoon (viz., the dry season). I have seen it
