THE BUTTERFLIES OF CEYLON 121 
It,is especially common at Haldummulla, and can be taken 
all the year round. Specimens from Jaffna and Mannar are 
usually very small. 
It varies little, except in the size of the white discal band 
on the upper side of the hind wing. It flies low and settles 
on the ground or short grass, and never goes far if disturbed, 
so is very easy to capture.

200. BARACUS VITTATUS. Peculiar to Ceylon. 
The male varies in the size of the white patch on the fore 
wing, and the spots in interspaces 6 and 7 may be absent. In 
the female these spots are also sometimes absent, and those 
in interspaces 2 and 3 may be very small; the amount of 
white scaling on the lower wing also varies considerably, 
It is exceedingly plentiful on patanas at high elevations, 
especially on the Horton Plains. It may occasionally be 
taken on grass by the roadsides as low as 3,000 feet at 
Haldummulla, and I found it common at Galaha, near Kandy. 
Those taken below 4,500 feet are usually smaller than those 
from the highest elevations. | 
For prehensores see Plate 4, figs. 15 and 16. They bear a 
very close resemblance to those of B. subditus from Coorg. 
201. SUASTUS GREMIUS and f. SUBGRISEA. S. gremius 1s 
also found in India, Burma, China, etc.; swbgrisea is con- 
fined to Ceylon. 
Moore gives subgrisea as a distinct species and says it differs 
in having the three discal spots smaller, the sub-apical spots 
very indistinct, and the under side less gray. S. gremius 1s 
a most variable insect, but all my varieties grade perfectly 
with one exception. This specimen was taken on this estate. 
It is smaller than usual, and the ground colour above and 
below is much darker. The only markings above are two 
minute spots, one each in interspaces 2 and 3 of the fore wing. 
Below, in addition to these spots, there are very minute 
black dots in interspaces 6, 7, and 8 of the fore wing, and a 
small black spot in the cell of the hind wing ; the discal series 
of black spots is wanting. This may be the insect named
