rescued, September’ 8, 1911, by one of his native collectors 
from a M’lanje Bulbul (Phyllostrephus milanjensis). The head 
was wanting, and there were symmetrical injuries at the anal 
angle of the hind-wings similar to those so often seen in living 
butterflies. 
2. Two wings of Precis archesia, Cr., ©, and the fragments 
of a Blattid, probably of the genus Deropeltis, taken June 25, 
1911, from a spider’s web. When noticed four days earlier the 
wings of the Precis were still attached to its body, and the 
latter had been attacked in the manner characteristic of a 
largish spider. The butterfly had probably sheltered in the 
thatch to which the web was fixed. 
Instances OF MIMICRY EXHIBITED BY CERTAIN SARAWAK 
Insects.—Professor Pouuron also exhibited specimens sent 
by Mr. J. C. Moulton from Sarawak, and said that before 
doing so, and reading Mr. Moulton’s account of them, he 
wished to acknowledge the kind help he had received from 
Mr. C. J. Gahan, who had compared several of the Coleoptera 
with the types, and had described one new species of Daphisia, 
and also the kind assistance rendered to him by Sir George 
Hampson. He then communicated the following paper by 
Mr. J. C. Moulton :— 
*‘ Among some recent additions to the insect collections in 
the Sarawak Museum, I noticed certain curious species which, 
by their remarkable resemblance to species belonging to very 
different families, afforded excellent examples illustrating the 
theory of mimicry. As some of these new captures prove to 
be new species, and as unfortunately they add to their rarity 
and value by being unique specimens, I have thought it 
advisable to send them to England for lasting preservation in 
some well-known entomological museum, where they will be 
safe from the ravages of a tropical climate and at the same 
time easily available for inspection and study. With this end 
in view it seemed a good opportunity first to draw attention 
to the meaning of the coloration exhibited by these insects, 
and so I am asking my friend and former teacher, Professor 
Poulton, to be kind enough to exhibit the little collection on 
my behalf at one of the meetings of the Entomological Society 
before giving them a permanent place in the Hope Collection.
