66 THE BUTTERFLIES OF CEYLON 
114. SURENDRA QUERCETORUM, var. DISCALIS, De N, 
Surendra discalis, M.; Surendra quercetorum discalis, E. 
Discalis is smaller than quercetorum, which is found in 
India, Burma, and the Dutch Indies. (See my remarks in 
the preface.) 
Formerly common at Haldummulla, but Acacia cesia, 
its food plant, is apparently being killed out by Lantana here. 
I have also taken it at Wellawaya, Matara, Kegalle, 
Madampe, Dambulla, etc. It is plentiful at Kandy. 
None of my specimens show any conspicuous variation, ex- 
cept in size. It generally settles on a bush at no great height, 
and if disturbed flies a short distance only, so is easy to catch. 
Usually there are several specimens together, so if one is 
caught, an examination of the bushes near will probably lead 
to the capture of others. 
115. AMBLYPODIA CENTAURUS PIRAMA. Arhopala centaurus 
pirama, De N. and E.; Nilasera pirama, M. 
A. centaurus is found in Burma and Malaya; the race 
pirama is confined to S. India and Ceylon. It differs in both 
sexes in the brilliant blue colour on the upper side. 
Variation in colour in Ceylon seems to be confined 
to relaxed specimens. Unrelaxed specimens are usually 
much brighter, and it is therefore difficult to separate a race 
on account of the brilliancy of its colour. 
Tt is occasionally seen settled on wet patches on the roads 
in the low-country of Uva, and I found it once in abundance 
at Obergoda, on the Muppane-Pottuvil road, in June, in the 
dry bed of a river. It only flew a short distance and settled 
on the bushes, so was easy to catch. 
I have specimens caught at Kandy and Trincomalie in 
April. | 
116. AMBLYPODIA AMANTES, Riley. Arhopala amanies, 
De N. and E.; Nilaserva amantes, M. 
Also found in India, Burma, the Andamans, etc. 
It can at once be distinguished from the last by having a 
distinct lobe in the anal angle of the hind wing. 
I have not yet taken it in Uva, but found it common near
