44 Frank Finn — Theory of Warning Colours and Mimicry. [No. I, 



May 22nd. — No buttei'flies left to-day but dead Junonia. No flies. 

 The wings of the moth were torn, and later only the wings were found, 

 so that some lizard had at last eaten it. I put in a headless cockroach, 

 which was soon attacked, but the lizard apparently got pricked in the 

 mouth, and the insect was not eaten. I put in in the evening two 

 Catopsilias, two Papilio eurypylus, one Euploea, one Banais genutia, and 

 a few small dragonflies. Almost immediately a Catopsilia was seized, 

 but relinquished by a lizard. I saw another lizard with the Euploea 

 in its mouth, which it ate. Shortly after I found a wing of one Papilio. 

 A Mynah's egg untouched all day. 



May 23rd. — Every butterfly gone but a Catopsilia, which was re- 

 cently dead and unmutilated though the wings were somewhat torn, 

 it appeared to have died naturally, it was the same specimen which I 

 had seen taken and left yesterday. No flies were in the cage, and the 

 cockroach left yesterday was not eaten. I took out the Catopsilia. 



Experiments with Lizards in Confinement. Serees B. 



I now liberated three of the lizards, reserving only the finest. I 

 put in two large black and yellow dragonflies in the evening. 



May 21th. — These dragonflies were uneaten, ■ though the lizard had 

 apparently had no food since the 22nd. I saw about this time some 

 other small dragonflies, apparently those put in before. I jDut in a 

 large protectively-coloured moth, which before long disappeared. 



May 2%th. — The lizard, which now seemed to be very hungry, ate 

 three or four cockroaches when put in, before Mr. Barlow's eyes, but left 

 more still uneaten by the evening. I then put in one each of Banais 

 limniace, B. genutia, B. chrysippus, Euploea, and Catopsilia, and a large 

 brown species. I soon saw the lizard swallowing the D. chrysippus, 

 none of the others having been attacked as yet. I then put in a large 

 protectively-coloured moth, much like the Yellow-underwing. 



May 29th. — In the morning B. limniace was alive and unhurt, but 

 none of the other insects put in were to be seen but one cockroach. 



Three hours later, B. limniace being still untouched, I put in a 

 large grey fly, which the lizard immediately ate, as it did another put 

 in some little time after. Not long after I put in a third, and the 

 lizard rushed past the B. limniace and eagerly took it. 



A small gecko put in was not attacked : soon afterwards the 

 B. limniace was gone, some of its wings being left, and the cockroach 

 still there, and I put in a Papilio eurypylus, which was uneaten when 

 I left. 



May 30th. — The Papilio was gone this morning, but the gecko and 

 some cockroaches were still there.
