AUGUST 26th, 1897. 
Mr. R. ADKIN, F.E.S., President, in the Chair. 
Mr. Tutt exhibited an egg of Polyommatus (Lycena) corydon 
laid by a ? on her own hind wing. He remarked that the 
egg of this species was so far undescribed. Its superficial 
resemblance, viewed from above, to a dahlia blossom was 
very remarkable. 
He also exhibited a living ? specimen of Mantis religiosa 
from Aix-les-Bains, captured on Friday, August 13th. He 
had fed it on cockroaches since the previous Saturday. It 
did not even disdain to taste a worm, but the care with 
which the animal cleaned its feet of the slimy material 
afterwards suggested that it was unusual. 
A further exhibit by Mr. Tutt were three Hymenopterous 
nests, each of which had been attacked by the larve of 
Aphonua sociella. (1) A nest of Vespa rufa received from 
Mr. Tuck, also male, female, and neuter of the wasp. This 
nest was taken on August 13th, at which time the Afphomia 
larvee had attacked only the roof and not the body of the 
nest. It had been removed from a hole about one foot deep 
in a bank. (2) Part of a nest of Bombus lapidarius taken 
on August 18th, 1897, together with male, female, and neuter 
specimens of the bee. It had been taken from a rat’s hole 
in a pigsty, the bees having utilised the old nest of the rat. 
The mass of the whole nest weighed eighteen ounces. (3) 
A nest of Bombus latreillellus. This was taken on August 
23rd, 1897, and male, female, and neuter specimens of the 
bee were also shown. It was found deep in a mouse’s hole 
ina pasture. All the specimens came from Tostock, near 
Bury St. Edmunds. 
Mr. Robert Adkin exhibited series of Bryophila muralis 
(glandifera) and B. perla from Poole, Dorset, and a series 
of the latter species from Eastbourne, Sussex, for comparison. 
Referring to the Poole series, he mentioned that the muralis 
were all taken on walls within a quarter of a mile of the 
quay, whereas the more inland walls produced nothing but 
perla, hardly any of which species were found on the walls 
producing the muralis. Comparing the two series of perla, 
he pointed out that the ornamentation of the Poole examples 
consisted entirely of black and grey markings, what little 
variation there was being caused by the greater or less 
amount of these colours present, whereas in those from 
Eastbourne there was the addition of a bright ochreous
