also in Coleoptera, sixteen specimens of Necrophorus ruspator, sixteen 
N vespilo, and four N humator , all taken under one dead rabbit, and 
specimens of Dorcus parallelopipedus, Prionus corarius and Philonthus 
splendens. Mr. Heasler, Apion cruentatum and A. spencei from 
Totteridge. 
Thursday , 20//* October , 1892.—Exhibits : Mr. Hollis, Colias hyale and 
C. edusa var. helice, also a series of Peronea variegana and living larvae 
of Aspilates citraria. Mr. Batlley, a variable series of Apamea didyma 
and Noctua festiva , all from the London district; also on behalf of Mr. 
Nicholson, a series of Va?iessa urticce . Part of these were bred from 
larvse taken at Leigh, Essex, and showed a remarkable tendency to var. 
ichnusa (/.<?., without the two black spots in the centre of the forewings) 
two specimens being absolutely without these spots, and the rest only 
having them slightly developed. The other specimens, bred from 
Clapton larvse, were all brightly coloured and dark. Mr. Clark, Peronea 
cristana and P . umbrana from the New Forest; also on behalf of Dr. 
Sequeira, a box of insects from the same district, including Agriopis 
aprilina, Cidaria psittacata, Peronea cristana, Leptogramma liter ana, 
Sarrothripa revayana. Mr. Hill, Cymatophora or from Rannoch and 
Winchester, the latter being larger and more distinctly banded, also C. 
ocularis from Wicken, and Melanippe fluctuata from Orkney. Mr. 
Smith, Calligenia miniata from the New Forest. Mr. Riches, a bred 
series of Bombyx neustria from Chingford. Mr. Prout, Agrotis segetum 
from Sandown. Mr. Goldthwait, dark forms of Boarmia abietaria. 
Mr. Bayne, Lycccna bellargus ( adonis ), L. icarus {alexis), and Z. corydon. 
Dr. Buckell also exhibited these species, and made some observations 
respecting the differentiation of the males of adonis and alexis. After 
pointing out that alexis was occasionally bright blue and adonis lilac 
blue, he stated that the fringes of alexis were usually said to be white, 
but in all the specimens he had examined, it was divided into two zones, 
a dark one nearest the wing, and a pale outer margin, and although the 
dark portion was occasionally barred, as in adonis, the bars did not 
extend to the light zone. On the underside, this was still more marked, 
the bars in the fringe of adonis being quite distinct, and those in alexis 
disappearing almost entirely. Mr. Tutt stated that some years ago, he 
had taken a local form of Z. adonis perfectly resembling alexis in colour, 
and further pointed out that the specimens of alexis from the North 
of Ireland were brightly coloured, and often had a row of black spots 
on the margin of the upper side of the hind wings, similar to adonis. 
He also stated that he agreed with Dr. Buckell in considering these 
species as quite distinct, for although he had repeatedly seen them in 
the same spot, he noticed no instance of interbreeding. Several other 
members made further remarks on the subject, and on the motion of 
Messrs. Goldthwait and Tutt, a vote of thanks was accorded to Dr. 
Buckell. Mr. Milton exhibited Sesiaphilanthiformis , S. chrysidiformis, 
S. iclmcumomformis, Agrotis ripce and A. corticea ; also in Coleoptera, 
Ocypus ater, Leistotrophus nebulosus , and Aiomaria fimetarii. Mr. 
Heasler, Colon serripes and Gronops lunatus from Mitcham. Mr. Clark, 
a perfect albino of the House Sparrow, shot at Rayleigh, Essex. He 
also recorded the occurrence of the Great Shrike on the Hackney 
Marshes.
