114 THE BUTTERFLIES OF CEYLON 
black, but sometimes the terminal half is irrorated with golder. 
yellow scales shaped like a sword blade ; these are grouped 
between the veins, forming a row of post-discal diffuse spots. 
On the under side of the fore wing, in addition to the pre- 
apical spots, there is sometimes a straight row of five spots, 
viz., three from the costa to the middle of the cell, a round 
spot in interspace 2, and a smaller one below in interspace I. 
There is also occasionally a large very diffuse spot at the apex 
of interspace I. On the hind wing some specimens have 
complete discal and post-discal rows of very diffuse orange 
spots ; in others all these spots are absent. When present 
they are formed by sword-shaped scales as above. 
It is usually found in jungle from 2,000 to 6,000 feet eleva- 
tion, and settles with its wings spread out flat on the under 
side of a leaf ; if disturbed it seldom flies far. It is very active 
in the net, and the wings rub easily, so perfect specimens are 
not easy to procure. I have not yet seen a female. 
It is plentiful at Haputale, and not rare at Haldummulla, 
and occurs at all times of the year. I have also specimens 
from Kandy and the hills above Ratnapura. For prehensores 
see Plate 4, figs. I and 2.

thyrus, M Also found in Southern India. 
Evans says: “ C. fusca can easily be separated from spilo- 
thyrus by the chequered cilia.” In several of my specimens 
the cilia of the hind wings are distinctly chequered. Elwes 
and Edwards point out that in C. fusca the costal spot “is 
usually, but not always, white, whereas in Ceylon specimens 
“it seems to be always yellow.” Moore says this spot is 
white in the male, and yellow in the female. He may be 
right. In every specimen I have seen it was yellow, though 
varying in depth of colour, but I have never seen a male from 
Ceylon, 
It varies greatly in the size and shape of the spots on the 
fore wing, and one or both of those in interspace I are often 
missing. The definition of the golden-yellow spots on the 
hind wing is very variable, and they may be entirely obsolete
