feci in a wasp’s nest. However that may be, there can be no cloubt 
that the cluster we record was formed in the orthodox fashion, in a 
Humble-bee’s nest, as it was placed in an exactly similar position to 
that in which Humble-bees generally build, and also, whereas there 
was not even the remains of one wasp to be seen, there was an 
abundance of the remains of Humble-bees.” 
Mr. Tutt also exhibited, on behalf of Mr. W. E. Butler, of Hayling 
House, Reading, two specimens of Ar<pjnnu lathonia, which had been 
sent to him by Mr. B. Stafford Chope as British, and read the following 
notes received from him (Mr. Butler):—“As A. lathonia is one of those 
species, British specimens of which have a high money value, it 
appears advisable that a record of all captures of such should be made. 
The first specimen was sent from Axminster, Devon, on April 3rd, 
1894, with the following note :—‘ I have sent you an A. lathonia as a 
speciality; l only took five last season (they came from Roseberry 
Woods, near Exeter), and I hope you will admire it.’ On Dec. 3rd, 
1895, Mr. Chope, writing from 117, Queen’s Gate, S.W., offered 
me another specimen, stating:—‘I have to spare a very fair 
specimen of latona, one of three I took this year in Hants.’ This 
was forwarded on December 10th, with a letter in which the 
following reference to the insect occurs :—‘ Be latona. General state¬ 
ments such as the one you refer to in Mr. Barrett’s new work are 
usually far from being correct. In that case, I may mention that I 
myself have taken seven A. latona in the last four years, and I know 
another collector (who visits the same locality as myself), who took 
eight this year alone.’ Of course I wish in no way to prejudice 
Mr. Chope’s captures, but think that I should point out that the cap¬ 
ture of five specimens at ‘ Roseberry Woods ’ and the capture of three 
specimens ‘ in Hants,’ make a total of eight, and not seven specimens, 
as Mr. Chope concludes. Both specimens are loose on their pins.” 
Mr. May read the following notes :— On the Variation in the Colour 
of the Cocoons of Saturnia pavonia. —I have written the following 
notes on the breeding of Saturnia pavonia, as I think that they may 
possibly be of interest, especially so far as they refer to the coloration 
of the cocoons. 
“ During the winter of 1894, both Mr. Bell and myself received a 
dozen pupte of this species from a correspondent in Yorkshire ; these 
were, without exception, in dark cocoons, and, judging by the moths 
which I bred, I should say that the larvie had been starved. However, 
Mr. Bell managed to obtain ova from a pair of his, some of which he 
gave me. Knowing what poor specimens the parents were, I made up 
my mind to be particular about the feeding of the larvae, so as to breed 
larger specimens next year if possible. 
“ They were fed on whitethorn, and I can safely say that throughout 
their existence, they were never without a supply of fresh food. The 
cage in which they were kept was made of zinc with a glass dome, being 
light, well ventilated, and having a layer of dry moss and sand at the 
bottom. Nineteen spun up, some on the glass or zinc, but mostly on, 
and in some cases under the moss. Of these nineteen, eighteen were 
more or less pale coloured and only one dark. To return to the rest 
of the brood (those in Mr. Bell’s keeping), he tells me that he kept his 
larva 3 under a glass shade without ventilation, with the result that 
they were always in a damp atmosphere, often very much so, he also
