THE BUTTERFLIES OF CEYLON 3 
found in Java. He names the North Indian form septen- 
trionis, that from South India—dravidarum, and our Ceylon 
form, which is intermediate in colour between them, 
mustkanos. Material in the British Museum is insufficient to 
prove whether our form can be separated from those of India. 
It occurs in the same places, and at the same times 
as limniace, but is far more numerous. It usually shares 
with Eupicea asela the honour of starting the NE. monsoon 
flights. Its flight while migrating is much slower than that 
of limniace, and it is not addicted to settling on wet roads; 
otherwise its habits are similar. 
Occasionally, during the flights, hundreds of their wings 
may be found in places along the roads. I believe this to be 
mainly the work of the White-bellied Drongo (Dicrurus 
leucopygialis), as I have watched this bird catching them, 
eating the body, and dropping the wings. I have also seen 
the blood-sucker lizard (Calotes sp.) eating them. 
It is found everywhere in the Island all the year round 
but is most abundant during the NE. monsoon. 
5. DANAIDA (SALATURA) CHRYSIPPUS. 
Found in Europe, Africa and Southern Asia. 
The most sedentary of all the Ceylon Danaids ; it may be 
found day after day in the same place, if disturbed it flies off 
but soon returns. It apparently does not join in the flights. 
Specimens from Haldummulla are usually much smaller 
than those from the low-country, although the food plant is 
very abundant here. It is found all over the Island all the 
year round, It is slightly variable, and Mr. A. C. Hayley 
has shown me a series, bred at Galle, in which the white 
marginal spots on the hind wing are obsolete. 
Var. dortppus. In this the black apical patch and the 
white sub-apical band on the fore wing are wanting. It is 
very rare, the only specimens I have seen till recently being 
four in the Colombo Museum collection. I have now received 
one from Giants Tank, Mannar district. It is common in 
Africa. 
Var. alcippus. In this the lower wings are suffused with 
white. There are two specimens in the Colombo Museum 
but I have seen no others I have a female which shows a 
tendency to approach this form, veins 2, 3, 4 and 5, on the
