out of the cocoon. Mr. Bayne; four eggs of the Willow Wren 
(Phylloscopus trochilus), two of which were rather long and speckled 
with very small reddish dots, while the other two were roundish and 
marked with reddish blotches. Mr. Battley reported that he had 
recently taken Nyssia hispidaria in Epping Forest by “ assembling ”; 
on a frosty evening he secured about 20 males, but on a warm evening 
nearly 70 rewarded his exertions; he also stated that he had found a 
S Hybernia marginaria paired with a 2 Phigalia pedaria and that he 
had obtained ova from the latter. Mr. Tutt, in connection with an 
exhibit of some South African flowers and of insects caught by them 
which had been sent to Mr. Hope Alderson of Farnborough, said that 
the local name of the plant is the “ moth-catcher ” and that the flowers 
close on any insect settling on them and hold it fast till it dies. Mr. 
Alderson hoped to receive some seed of the plant, which he would try 
and rear. Mr. Tutt also passed round an auctioneer’s catalogue of a 
sale of the Duchess of Portland’s collection in 1786. Mr. Bacot 
exhibited pupa-cases of Saturnia pavonia, Bornbyx quercus, Odonestis 
potatoria, Dasychira pudibunda and Ocneria dispar, and made the 
following remarks:—“ It occurred to me that, as many apterous 2 s 
have the wing-cases well-developed in the pupa, possibly the 2 s of 
other species might have specially male characters developed in the 
pupa. An examination of the pupa-cases of the species exhibited 
to-night yielded the following results : In S. pavonia, D. pudibunda and 
0. dispar the antennae-cases are nearly as well developed in the female 
as in the male pupa, whilst in the imagines the antennas are only very 
slightly pectinated in the 2 and only occupy a small portion of the 
space covered by the pupal cases. In B. quercus there is no develop¬ 
ment suggestive of pectinated antennae in the pupa, though the antennae- 
cases are rather more raised in the male than in the female pupa; in 
0. potatoria the development is hardly noticeable; in the imagines of 
both species the pectinations are strongly marked in the $ s, slightly 
so in the 2 s, the latter species being rather the more favoured in this 
respect. From these facts I am inclined to think that the first group 
have evolved from a type or types that had the pectinations of the 
antennas well-developed in both sexes and in which, probably, either 
sex would be attracted by and fly to the other, that the 2 s subsequently 
lost the pectinations through disuse, whilst in the $ s of S. pavonia 
they have been still further developed. In the second group the 
evolution would seem to have been from simple to pectinated antennae, 
the S s having advanced farthest in this respect, whilst the pupae have 
not yet fully responded to the change.” Mr. Routledge exhibited a 
collection of Coleoptera taken by him near Carlisle, among them being 
Silpha nigrita, Coccinella 14 -punctata, Pterostichus versicolor, Amara 
ovata, Limonius cylindricus and Barynotus schbnherri. Mr. Tutt read a 
paper on “ Nature’s Scents,” in which he pointed out that, as a rule, it 
was the inconspicuous flowers which had the richest perfume, blue and 
red flowers being mostly devoid of odour; that this development of 
perfume subserved the purpose of attracting insects to the blossoms and 
so ensured cross-fertilization; other scents, both in the animal and 
vegetable kingdom, were disgusting and probably subserved a protective 
function. Mr. J. A. Skertchley mentioned the case of a South American 
flower which was of a deep red colour; it was perfectly scentless by 
day but during the night, when its colour rendered it practically
