CEYLON BUTTERFLIES. 159 
below. They are formed by sword-shaped scales identical 
with those of H. infernus, but, when especially well marked, 
there is also a mixture of broader scales. 
It is found in the same localities, and has the same habits 
as H. infernus, but, whereas the female of infernus seems 
unprocurable, in spilothyrus the opposite is the case, and I 
have not yet seena male. This, coupled with the resemblance 
in habits, venation, 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. 
My specimens are from Haldummulla, Haputale, Kandy, 
and the hills above Ratnapura. 
“ Occurs in jungles about 3,000 feet elevation, mostly July 
to September ” (F. M. Mackwood). 
193. SARANGESA ALBICILIA.—Peculiar to Ceylon, but 
probably a race of S. dasahara of India. It only differs in 
having the under side of the hind wing white. The prehen- 
sores seem to be identical. (See Pl. 4, figs. 1 and 2.) 
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 1 to 5, in other specimens there 
is no trace of these. 
In May, 1917, it was apparently ‘“ flighting ”’ at Haldum- 
mula, 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 
Trincomalee in November, and have received specimens from 
Kandy taken in August. 
“Numerous in the Kandy—Matale heavy chenas” (F. M. 
Mackwood). 
194. CoLADENIA TISSA, M.; Coladenia indrani, De N.; 
Cnaiolade indrani tissa, K.—Probably a race of C. indrani, 
which is found in India and Burma. Elwes and Edwards 
distinguish tissa from indrani by the “distinct displacement 
inwards of the middle one of the three pale spots which form 
the sub-apical series.” In my specimens these spots vary in 
number from 2 to 5, though 3 is most usual.. The spot in 7 is 
usually displaced inwards, but the displacement is sometimes
