46 Frank Finn — Theory of Warning Colours and Mimicry. [No. 1, 



July Ibth. — Offered in the evening a Danais genutia to a large 

 lizard, which ultimately took and ate it with much chewing. 



July 16th. — Put one specimen each of Vanais genutia and D. Urn- 

 niace near a lizard, which did not seem inclined to attack them. I 

 therefore put them before another, which, after a while, passing close 

 to the D. limniace which was lying still nearest to him, seized the 

 B. getiutia, and when approached went off with the insect in its mouth. 



The -D. limniace was dead, killed by ants when first put out, I think. 

 In the evening I put an Eujploea near a big Galotes, I believe the same 

 to which I had offered this butterfly before (July 12th), but though I 

 left it there for some time, it was not taken. 



July 17 th. — Offered an Euploea to a fat and sickly-looking lizard, 

 probably heavy with eggs. The insect was not touched, though left 

 near for some time. 



I put the butterfly not far from another lizard, and not long after 

 saw a lizard (apparently not the same individual) with it in its mouth. 

 The lizard ran off with its prey. Exposed a Euploea on a tree trunk 

 for some time within a few inches of a big lizard. Ultimately it dis- 

 appeared, and the lizard appeared to have moved further up. 



July ISth. — In the evening put an Euploea and a Catopsilia on rough 

 ground near a fair-sized lizard, the Catopsilia being a little the further 

 off. The lizard stalked, seized, and ate the Euploea. A bigger lizard, 

 which had watched the proceeding with apparent interest, then took 

 and ate the Catopsilia., more quickly than the other had done the 

 Euploea, no doubt because this butterfly was smaller. He did not 

 attack at once, though apparently in no fear of the other. 



Exposed specimens of Banais genutia and a plain-coloured species 

 to two lizards, but failed to attract them ; they were probably afraid 

 of me. 



July 24ith. — Offered a non-warningly-coloured species to a large 

 Calotes near the tank, with a Banais genutia placed nearer the lizard. 

 After a time the lizard took and ate the Banais before my eyes. Put 

 a B. genutia and a non-warningly-coloured specimen near a lizard on a 

 tree. I waited some time, but neither was touched ; the lizards had been 

 a little frightened. 



Threw a B. genutia almost under the nose of a big Calotes on the 

 tree, but though I waited some time, he did not catch it, but moved off 

 towards another lizard. 



Jtdy 27th. — Put specimens of Banais limniace and Papilio demoleus 

 not far from a lizard (near the tank). He did not attack, but after a 

 time I found only the wing of the B. limniace j and another lizard ran off, 

 which might have taken it.
