CEYLON BUTTERFLIES. 55 
of eight spots, of which the middle three or four are crescent- 
shaped. I have taken both forms together, and think they 
are only seasonal. They apparently grade into one another. 
A very local fly, and apparently found only in the driest 
districts. 
It is very abundant on the bund of Tissamaharama tank, 
and the sand dunes at Kirinda in the Hambantota District, 
in February and March. Also on the bund of Murunkan tank, 
near Mannar, in November. Fairly common at Kankesan- 
turai on the north coast, and at Fort Frederick, Trincomalee. 
It flies slowly near the ground and frequently settles on 
flowers, so is very easy to capture. 
109. Tarucus puinius, M., B., & E.; Tarucus telicanus, 
De N.—Also in Africa, India, Burma, Malaya, and Australia. 
Very plentiful at Haldummulla, and I have taken it in every 
month but December. Its range extends from sea level to 
over 6,000 feet. 
I have taken it at Jaffna, Mannar, Vavuniya, and Hamban- 
tota, but not in the wet zone. 
The male frequently settles on wet roads, and when dis- 
turbed has a rather quick flight, and does not usually return. 
They are easiest to catch when flying round Indigofera anil, 
which is, I fancy, the food plant. 
‘“* Also on the seed pods of the “ise. and _ blue-flowered 
plumbago plant ” (F. M. Mackwood). 
110. CastTaLivus Rosimon.—Also in India,. Burma, 
Malaya, &c. 
Very plentiful all over the low-country of Ceylon, but 
becomes rarer above 3,000 feet;.. dt is commonest at Haldum- 
mulla in the dry season, June-August. 
T have noticed it all over the low-country, from Galle to 
Jaffna. It prefers open country, and especially road sides ; 
flies slowly, and is very easy to catch. It settles in numbers 
on wet patches on the roads. 
It varies a great deal in the amount of black on the upper 
surface, but the variation does not seem to depend much on 
climate. Several of my lightest-marked specimens are from 
Galle (wet zone), and my two darkest are from Haldummulla 
(medium) and Jaffna (dry zone).
