them. I found two D. chrysippus wings on the floor, and took out the 

 dead plain-coloured specimens and the mutilated D. chrysippus, leaving 

 the other still alive. 



May 15th. — A few flies were still about. The D. chrysippus left 

 overnight was dead but uneaten, though its head seemed to have been 

 chewed. 



I put in one Junonia and one Euploea, and one each of Danais genutia 

 and chrysippus. Plenty of flies were soon to be seen, yet at the end of 

 the afternoon all the butterflies seemed to have been eaten. In the 

 evening, I put in one each of Danais limniace, genutia, and chrysippus, 

 and seven non-warningly-coloured specimens. Before leaving, I saw a 

 lizard with the D. limniace in its mouth. 



May IQth. — Found a Junonia (dead) and & Catopsilia (alive) floating 

 in the water-pan ; two other plain-coloured specimens on the ground, 

 dead, apparently from natural causes ; one D. chrysippus, living, but 

 minus much of its forewings, and many flies, nothing else. At the end 

 of this day the Catopsilia was dead, apparently naturally, and the 

 D. chrysippus had disappeared, though there were flies about. I then 

 put in four male Elymnias undularis, one Papilio aristolochiae, and one 

 Euploea. 



May 11th. — To-day I found three Elymnias and the Euploea unhurt, 

 but only two wings of the Papilio aristolochiae, which Mr. Barlow had 

 seen a lizard trying to catch ; there were flies to be seen. Before long 

 I noticed an Elymnias notched; later two of these disappeared. I 

 found the dead Catopsilia apparently eaten ; possibly others had been 

 also. I put in one D. limniace and two non-warningly-coloured specimens. 



May 18th. — The Euploea remained alive and untouched all day. 

 I found the Elymnias recently dead, with antennae gone and wings 

 notched. The others had disappeared. There were flies in the cage. A 

 large cockroach was soon mostly eaten. I put in some fresh maggots. 



May 20th. — The Euploea, dead naturally, untouched, as also the 

 dry body of the Elymnias. Some dead plain coloured specimens have 

 been untouched all the time. 



May 21st. — There were hardly any flies in the cage and I gave the 

 lizards two large grey ones. In the evening I put in one each of 

 Danais genutia and limniace, and Euploea, two Catopsilia, and one 

 Junonia (this last dead). Soon a Catopsilia, going very close to a 

 lizard, was snapped at, without hurry, but escaped by the tearing of its 

 wing, to be soon eaten by another lizard which got a hold on its body. 



A very large silkworm moth was in the cage most of the day, but 

 not attacked. Mr. Barlow saw a lizard approach, but stop at some 

 distance, apparently frightened.
