356 Frank Finn— Theory of Warning Colours and Mimicry . [No. 3, 
A protective species was again eaten; then a male Elymnias 
undularis , swallowed whole. 
A D. genutia was allowed to remain perched on a shrub. 
I did not see one Danais at this time eaten, though one D. genutia 
was torn up ; but I found the body left. Afterwards, however, I saw one 
Danais (I do not know which species) eaten, and then a D. genutia ; this 
latter was thrown up several times. Another was eaten; and then 
I had to leave the birds. 
January 18£7i.— The birds were still about, though one seemed to 
be missing. I saw some D. chrysippus lying about, left from yesterday. 
In the morning I offered the Babblers a large brown moth and a cock¬ 
roach, which were taken. The birds, however, did not seem to wish for 
some rice, &c., which I threw out, though such had formed their ordi¬ 
nary food in confinement, and they had eaten some the day before. 
In the late afternoon I offered them some butterflies, mostly decapi¬ 
tated, chiefly Danais genutia, but also D. ehrysippus , D. limniace , Euploea, 
and Delias eucharis. None of these were eaten, as far as I saw, as long 
as other species could be had, and only one, a D. genutia, afterwards. 
On the other hand, male Elymnias undularis , Catopsilia, and other non- 
warningly-coloured specimens were readily devoured, and even taken 
from my hand, while specimens of D. genutia fluttered about. A male 
Nepheronia hippia was taken and eaten. These experiments left not 
the slightest doubt in my mind as to the unpalatability of Danais and 
the other “ warningly-coloured” forms. Birds would often only look 
at them, and soon left them when picked up. 
Next day the birds had disappeared, and so, ended my experiments 
with this species.
