Mr. Mansel Weale had recorded his haying witnessed the 
capture of the ¢ Papilio cenea (the S. African representative 
of P. merope) by the Fly-catcher, Tchitrea cristata; and Mr. 
T. Ayres has observed that the small King-hunter, Ispidina 
natalensis, fed almost entirely on butterflies. 
The larger Madagascar Chameleons also ate butterflies, but 
appeared to show no discrimination. Lizards attacked them, 
but must necessarily see the undersides only, which were 
protectively coloured in many cases. 
As regarded the known protected butterflies, it should be 
borne in mind that there was very little difference in colour- 
ing and pattern between the two surfaces of the wings in the 
Danaine and Acraine, so that warning indications of dis- 
tastefulness were shown almost as conspicuously when at rest 
as when in flight. The importance of this as a means of 
protection was manifest, and was further evidenced by the 
fact that it was exhibited very markedly by the mimicking 
forms as well. 
The chief invertebrate enemies he had noticed were 
Asilide and dragon-flies. 
It seemed to him impossible to explain except by the theory 
of mimicry such cases as that of Danais chrysippus, a widely 
distributed and very common insect which was attended by a 
troop of mimetic species wherever it went. 
Dr. Dixey: It was too late to deal fully with all the points 
which had been raised, and he must necessarily leave some 
unanswered for that reason, and not because he undervalued 
their importance. 
He agreed with Canon Fowler as to the danger of making 
too much assumption upon a matter such as mimicry—it 
was a subject upon which he had no desire to dogmatise. 
His position was rather this :—Supposing the theory that 
such and such forms were inedible seemed to supply a 
provisional explanation of observed facts, it was desirable 
to work out fully the logical consequences of such a 
theory, and then to make a fresh appeal to observers for 
verification. 
Mr. Elwes had laid stress on the importance of getting 
more observations from naturalists resident in the country
