was dull and cloudy, and the insect was resting in a semi- 
torpid state among the flowers of the white dead-nettle 
(Lamium album) in a hedge. A week later, on May 13th, 
between 4 and 5p.m., when searching the same hedgerow, 
another individual was found in an almost identical position. 
Hanging in the midst of the largish white flowers of the 
Labiate the butterflies were beautifully concealed, and were 
indeed only found because the plants were carefully examined 
for other insects. 
“On August 17th, between 7 and 8 p.m., when looking for 
larvee on the hedge bordering my garden, near the Cowley 
Road, I found two rapx within a few inches of each other. 
Both were resting on the silvery under-sides of bramble leaves. 
In both cases, however, the leaves were twisted and the lower 
surface had become the upper. Again, on August 20th, in a 
lane leading to Temple Cowley, at 5.30 p.m., I watched an 
individual flying slowly along a hedgerow, every now and then 
resting for a few seconds. Finally, after many attempts, it 
settled down, apparently for the night, and on going to look 
more closely, I found that it also had chosen the under-side 
of a bramble leaf. Although not quite so well concealed 
as among the white flowers, these last examples blended 
wonderfully well with their environment. 
“‘ After some years of close observation of the resting habits 
of insects in general, I feel convinced that they possess an 
inherent tendency to select an environment that aids in con- 
cealment ; and as the various species differ in appearance so do 
they select diversified situations suited in each case to the 
particular requirement of the insect.” 
A discussion followed, Mr. H. J. Etwes expressing his 
conviction that the use of surroundings by insects, and Lepi- 
doptera especially, for protective purposes simply, was still an 
open question. Colonel J. W. Yersury mentioned the case 
of Luchloé euphenoides and Zegris eupheme roosting at 
Granada on plants of Biscutella, the appearance of the insects 
at rest closely approximating to that of the flower heads. 
Mr. H. Row.anp-Brown observed that he had noted a similar 
resemblance between a specimen of Pieris napi and the flower 
of Leucojwm on which it rested for the night. Mr. G. C.
