5 
so-called “ nickel ” pins contained a considerable amount of copper. 
Mr. Clark also distributed some of Dr. Knagg’s “ sulphuretted ” pins. 
These were the ordinary white ones, which, after being dipped, first 
into a nitrate solution, and then into hydrosulphate of ammonia, came 
out much hardened, and practically proof against the action of organic 
acids. Mr. H. A. Sauze read a paper on “ Alligators and Crocodiles.” 
March 5th, 1895.—Exhibits:—Mr. Bell: a female specimen of 
Argynnis adippe from the New Forest, having a small portion of the 
right fore-wing slightly bleached, but otherwise perfect. Mr. Clark : 
a short series of Cucullia gnaphalii from the collection of the late Mr. 
Machin, who bred them from larva? obtained at Sevenoaks. Mr. 
Southey: a series of Smerinthus popidi, among which was a specimen 
having the right hind-wing of a nearly uniform cream colour. 
Messrs. May, Handing and Biches also exhibited the same genus to 
help to illustrate a most instructive and comprehensive paper read by 
Mr. Bacot on “ The genus Smerinthus .” * The Secretary read a letter 
from Mr. Heasler to the effect that he had now completed the list of 
records of Coleoptera for the Society’s London Fauna List, and for¬ 
warded the same in manuscript, so that it might be of use to members 
during the coming season. The list comprised records of more than 
half the total number of species of British beetles, and was really a 
handbook of those occurring in the London district, inasmuch as it 
included much information as to methods of capture, besides localities, 
dates and other statistical matter. Mr. Heasler is to be congratulated 
on his most masterly production, for which the Society owes him a 
deep debt of gratitude. 
March 1 9th, 1895.—Exhibits:—Mr. Bate : living examples of Amphi- 
dasys betularia, a brood of which had been emerging since September 
last; also a specimen of Noctua xanthographa which bore a strong 
superficial resemblance, both in colour and markings, to some of the 
Caradrinas. Mr. May: a black specimen of Hybernia leucophaearia 
from Epping Forest. Mr. Bacot: a very perfect hybernated female of 
Gonepteryx rhamni, recently captured at Hayes Common. Mr. Camling : 
a series of Selenia tetralunaria, bred from Andover eggs; the males were 
all of the greenish form, as were also all the females except two, which 
were of the reddish form. Bev. C. B. N. Burrows: a dead pupa of 
Acherontia atropos, which had been dug up, and which he supposed to 
have been killed by the severe winter; all the tail segments were 
movable, owing to the rottenness of the pupa. Mr. May stated that a 
male Nyssia hispidaria had paired with three females, from each of 
which he had obtained fertile ova. Mr. Bayne remarked that H. de- 
foliaria was still on the wing in Epping Forest, it being just six months 
since he saw the first specimen. Mr. Prout read a paper on “ The British 
representatives of the genus Caradrina ” (vide, Ent. Record, vol. vi., 
pp. 198 et seq. and 223 et seq.).
