282 SPOLIA ZEYLANICA. 
Strange to say, the only trees seriously attacked were those 
bordering the Palmyra Avenue, others in private gardens 
near by not being touched apparently. The outbreak does 
not appear to have done any serious damage to the affected 
trees, however, as they are coming into new leaf and flowering 
vigorously now.

Flight of Brana callopasa —A very unusual sight attracted 
my attention whilst out collecting Cicadas. The lamp on the 
gate leading tc the Museum was besieged by what I at first 
thought to be a swarm of bees, but on closer inspection they 
proved to be moths (Brana callopasa, Wlk.). The lamp 
was covered with the moths which were about ten deep. The 
next morning I found every one had flown away.

Nacaduba dana, De Niceville—This butterfly is new to the 
Ceylon lists. It is allied to N. ardates, but can at once be 
distinguished by— 
(1) Much lighter blue on upperside. 
(2) Basal pair of strigz on underside of forewing not 
produced below median vein. 
(3) Two minute equal-sized black spots, one each in inter- 
spaces (1) and (2) of the underside of the hindwing. 
The last is the most useful distinction, as all the other 
Nacaduba of Ceylon have a large black spot in interspace (2). 
Mr. Mackwood has compared it with specimens of NV. dana 
from Burma and finds it identical. 
The male is found in the Haldummulla district settled 
on wet roads, chiefly in April and November. The female is 
very rare.
