1895.] Frank Finn — Th eory of Warning Colours and Mimicry. 353 
(e ) Small brown Satyr id butterfly offered with D. genutia ; former 
was deliberately cliosen. 
Some specimens of Euploea, Danais chrysippus, and D. genutia , were 
given alive, and immediately attacked by some of the birds. 
Two Papilio aristolochiae were tried and left, while some of the 
Danainae above-mentioned were being torn and eaten, though some were 
still alive or uneaten. The birds had food by them at the time. Later 
on offered them — 
(a.) A Danais genutia and a brown Satyrid species. The first 
comer having a fair field, first took the former, and then 
dropped it and took the other. 
(5.) Last experiment repeated; two birds came at once, and the 
Danais was first taken. 
(c.) Offered a Junonia and a D. genutia ; the former was taken first. 
(d.) Put in one Catopsilia , one Danais chrysippus , and two Papilio 
polites (one mimetic of P. aristolochiae, and the other not). 
The first comer deliberately chose the Catopsilia ; the next 
looked at the remaining three and turned away ; then a 
P. polites was taken, and I saw it swallowed nearly whole — 
I could not say whether by the same individual. The birds 
had food by them. None of the butterflies previously put 
in were to be seen. They did not seem very eager even 
for Catopsilia. 
IX. Offered to the Babblers killed or disabled specimens as 
follows :— 
(a.) One Danais chrysippus, one Catopsilia. Former taken first. 
(6.) One D. chrysippus , one Catopsilia. Latter taken first, by young 
bird. 
(c.) Same experiment repeated; Catopsilia taken first. 
(d.) Same experiment repeated with same result. 
(e.) One Danais genutia offered with one Catopsilia. Latter deli¬ 
berately taken first. 
(/.) Ore female of Dlymnias undularis , one Catopsilia. Latter taken 
first. The mimic also taken and swallowed whole. 
(g.) Papilio demoleus and Danais limniace. Former taken first. 
(7i.) Same species of Papilio and an Duploea. Papilio taken first. 
(i.) D. chrysippus and Papilio polites. Both of these were taken 
at once. 
U) Same experiment repeated. The first comer took neither, the 
second Papilio polites. 
( k .) Protectively-coloured Satyrid and D. chrysippus. Former taken 
first, and swallowed whole.
