Colombo, June 9th. A male Elymnias fraterna (undu- 
laris) was fluttermg round a female, which was at rest on 
a palm leaf about eight feet from the ground. There was 
a sudden rustle, and a green lizard (Calotes) ran along the 
leaf and snapped at them, but went just between them, 
and missed both. They at once flew to a higher leaf. 
Later the same lizard tried to catch a male Z. fraterna, 
but never actually had an opportunity. The lizard 
climbed down the palm towards the butterfly, which was 
fluttering up and down, and kept altering its poise ready 
to make a sudden rush, but the butterfly never came quite 
near enough. 
Finding the lizards quite near at hand, I tried to experi- 
ment with them, but unfortunately had only two days of 
showery weather before leaving the island, and material 
was scarce. I caught a fine Papilio aristolochiae, and, 
giving the fore-wing a twist near the base, offered it to 
the lizard at the end of a stick. It moved, and the lizard 
rushed forward and knocked it off the stick in its eager- 
ness for a meal. The butterfly flew away, and I could not 
procure a second. 
Colombo, June 10th. Caught two females of Z. fraterna, 
which in this sex mimics Danais plexippus in its colour 
and slow flight in the open; the male, dark brown in 
colour, is much more active, but rarely ventures far from 
its food-plant, the palm. 
I put one on a palm leaf near a lizard, where it remained 
still for twenty minutes before it flew off; and although it 
was in full view of the lizard, it was left unmolested. The 
second, which I treated in the same way, at once began 
to flutter, and the lizard eagerly dashed at it, but missed, 
and ran away to hide. 
To another lizard (Calotes) I offered a specimen of 
Telchinia violae, a distasteful species, on the end of a 
stick. It slowly opened and closed its wings. The lizard 
saw it at once, and, after poising itself, rushed forward, 
caught the butterfly by the head and thorax, and rapidly 
ate it all, including the wings, chewing it with gusto. 
Later I saw a male LZ. fraterna resting in full view of 
and very near a lizard, but it never moved, and was left 
untouched. 
The above observations bring out two or three interest- 
ing points. One is that so long as a butterfly remains 
still it is let alone, but is attacked as soon as it moves.
