128 SPOLIA ZEYLANICA. 
I have taken it from 500 to 6,000 feet elevation in Uva, and 
have specimens from Uda Pussellawa, Balangoda, and the 
hills above Ratnapura. 
f 150. Caroprsri1a crocaLE, B. & E.; Catopsilia catilla, M. 
< 151. Caropsm1a pomona, E.; Catopsilia crocale, M., B., 
L& De N.—Also found in India, Malaya, and Australia. 
De Niceville and Bingham treated these as one species, but 
Bell has found that their larve are distinct. They can be 
distinguished as follows :— 
Crocale.—A conspicuous reddish pearl-centred spot at the 
end of the cell on the under side of both wings. Antennze 
plum coloured. 
Pomona.—The spots at the end of the cell usually absent 
in the 3, and absent or inconspicuous in the 9. Antenne 
blackish-brown. 
C. crocale 3 varies very little. The 2 has two forms: one 
sulphur-yellow, and the other cream colour. The first is by 
far the most common. Var. catilla is the variety of 9 crocale, 
with large reddish blotches in the centre of the under side of 
both wings. 
C. pomona 3 varies in the amount of yellow on the upper 
side. The Qis very variable in ground colour and the amount 
of the black markings. I have no specimens of as bright a 
sulphur-yellow as normal 2 crocale. 
Both species appear in enormous numbers in the flights, 
but are not usually at their maximum at the same time. 
These flights of crocale will be found almost always to consist 
of well-grown specimens of 2 inches to 2} inches in expanse. 
In pomona, on the contrary, dwarfs of under 2 inches form the 
great majority. 
152. CaTopsILId PYRANTHE.—Moore divided this into 
pyranthe, ilea, and chrysets. Found also in India and Malaya. 
It is very plentiful at times everywhere, but chiefly so at a 
low elevation. It seldom appears at Haldummulla, except 
during the north-east monsoon flights, but I have often seen 
it laying its eggs then. This district is exceptionally well 
stocked with small insectivorous birds, and I fancy the great 
majority of the larve fall a prey to them. ‘To observe this
