THE BUTTERFLIES OF CEYLON 115 
below. They are formed by sword-shaped scales identicai 
with those of H. infernus, but, when especially well marked, 
there is also a mixture of scales of a different shape. 
It is found in the same localities, and has the same habits 
as H. infernus, but, whereas the female of infernus seems 
unprocurable, in spzlothyrus the opposite is the case, and I 
have not yet seen a male. This, coupled with the resem- 
blance in habits, and scaling, gives rise to a suspicion that 
infernus is the male, and spilothyrus the female, of our Ceylon 
form, Of course, this can only be proved by breeding. The 
difference in venation is not more than might be expected 
in different sexes of the same insect. 
Mr. Talbot informs me that the Hill Museum, Witley, 
have the specimen of spilothyrus which Swinhoe used to 
illustrate the g in “‘ Lepidoptera Indica ’’ and it proves to be 
a female, like all their other specimens of sfilothyrus from 
Ceylon. 
My specimens are from Haldummulla, Haputale and the 
hills above Ratnapura. 
I9gi. SARANGESA ALBICILIA. Peculiar to Ceylon, but 
possibly only a race of S. dasahara of India It differs in 
having the under side of the hind wing white. The prehen- 
sores seem to be identical. (See Plate 4, figs. 13 and 14.) 
It varies little. On the fore wing the discal spot in inter- 
space 2 is sometimes obsolete. On the under side of the hind 
wing there is sometimes a complete series of diffuse black 
marginal spots in interspaces I to 5, in other specimens there 
is no trace of these. 
In May, 1917, it was apparently “ flighting ’ at Haldum- 
mulla, and I caught a fair number of specimens. The 
direction of flight was west. It is usually a rarity here, but 
is very common in the low-country of Uva. I have taken it 
at Trincomalie in November, and have received specimens 
from Kandy taken in August.
