SPOLIA ZEYLANICA. 
M. ismene is an adept at concealing itself. It usually pitches 
amongst fallen leaves where its form and coloration are sufficient 
concealment. But even on bare ground the insect is often 
extremely difficult to localize, though the approximate spot may 
have been carefully noted. I have watched the fly, immediately 
after pitching, alter its position so that its axis is directed towards 
the sun, thus easting no shadow.

The Museum collection (No. 395) contains an unique aberration 
of the male of this species, taken by the writer at Haragama 
(Central Province), December, 1902. The ground colour is of the 
normal tint, but all definite lines streaks and spots have either 
completely disappeared or been replaced by nebulous fasciae (see 
%. 1 ). 
Upperside: fore wing bright yellowish fulvous, darkest on basal 
area and outer margin. The cell, with the exception of a median 
bar of the ground tint, is filled in with fuscous. The two 
marginal sinuous lines are replaced by a single series of diffused 
arches between the veins, the apex of each arch confluent with a 
deep fulvous ovoid nebulous spot. Other lines absent. Hind 
wing deep yellowish fulvous, with a broad diffused fuscous 
discal bar crossed by the pale nervules, this fuscous bar taking 
the place of the lighter area in typical examples. The usual 
ocelli are replaced by diffused whitis i spots. The median and 
marginal lines are totally absent. Underside yellowish fulvous ; 
the basal area suffused with ochreous pink. All definite lines 
absent. The cell markings as on upperside. A diffused white
