THE BUTTERFLIES OF CEYLON 107 
remain for a long time in the pupal stage. Jast year I had ~ 
six larve which pupated in May. Three hatched out early 
in June, one at the end of July, one in the middle of August, 
and the last inSeptember. The larve are usually to be found 
on orange and lime trees, but I have often seen the females 
laying their eggs on Todalia aculeata. I have bred a fair 
number from larve picked off my orange trees, but have not 
yet lost a single one through parasites, and I imagine their 
numbers must be mainly kept in check by birds.

clytia, var. lankeswava, IX.; Chilasa lankeswara, clytiordes, 
and dissimilzs, as three species, M. 
P. lankeswara has the same claim to rank as a race of 
clytia as Euplea asela has to rank as a race of core, as it 
differs in the same respects. 
Rothschild says that lankesiwara ‘‘ differs from P. clyfia 
in the umber brown colour of the wings, and in the small 
sub-marginal spots of the fore wings . . . . This 
sub-species has been described from slightly aberrant speci- 
mens, in which the sub-marginal spots of the fore wings are 
partly obliterated; in most individuals the series of these 
spots is complete, and on such specimens Moore’s clyiiordes 
is based.’’ | 
I have only a rather poor series, but they vary much in the 
number and size of these spots and of the discal sagittate spots 
on the hind wing. The umber brown colour seems constant. 
P. lankeswara is a mimic of the Eupleas, and it is curious 
that these, in Ceylon, differ from their corresponding Indian 
species in the same way that lankeswara differs from clyia. 
The form dissimilis mimics D. limniace and aclea, and is said 
to agree with Indian specimens. It varies greatly in size 
and the amount of the white markings. In both forms the 
females can be distinguished by their broader and more 
rounded fore wings. 
It has as rapid a flight as any Papilio in Ceylon, but does 
not always make use of its powers. When visiting flowers, 
or hovering over wet patches on the roads, its flight is slow, 
and so like that of a Danaida or Euplea, that after thirty
