Bacot kept this last ? apart from the rest, in order that special note 
might be taken as to whether her ova prove fertile or not, it having been 
the third time that same $■ had paired within twenty-four hours. 
Mr. Bacot thinks that there is probably a second flight, as the males in 
his cage again began to get lively about 10.30 to 11 p.m. 
Mr. Prout considered it probable that the abundance of N. hispidaria 
in 1893, was due rather to meteorological or local causes, than to immi¬ 
gration. He had done a good deal of larva-beating during the last few 
years, at the spot where Mr. Bayne found the moths most abundant, and 
the larva seem to have been steadily increasing in numbers, having 
been specially plentiful in 1892. The larva is not exclusively an oak 
feeder; it will thrive well on hawthorn, and hornbeam. As hawthorn 
is obtainable at least a month earlier than oak, a knowledge of its being 
accepted by the larvae may be useful to those breeding the species from 
ova. Mr. Prout was disposed to doubt whether it was safe to assume 
that the coloration of figures, even of those of Hiibner, was always 
accurate. He had long thought that there must be some kind of con¬ 
nection between winter emergence and the occurrence of apterous 
females, Orgyia, etc., being merely casual exceptions due to some 
different cause. It was certainly interesting to note that in the Amphi- 
dasydae, the earliest species have apterous females, while those that 
emerge later on are winged in both sexes, the solitary summer species, 
A. betularia, alone having the wings of the ? really well-developed. 
Mr. Clark mentioned birch as another plant on which the larvae 
readily feed, and remarked that, in pupating, the larva frequently 
descends as much as eighteen inches below the surface of the ground. 
Feb. 2 0th, 1894.—Mr. Heasler having sent in his resignation of the 
curatorship, Mr. Bayne was unanimously elected in his stead. 
Exhibits :—Mr. Battley ; ova of Diloba caendeocephala. Mr. Clark ; 
a short series of Gnopliria rubricollis from the New Forest, and a curious 
pad of felt-like material, resembling a pancake in appearance ; this had 
been spun in a pill-box by parasitic larvae, which emerged from a larva 
of Hepialus liumuli ; the disintegrated remains of the latter were attached 
to the pad. Dr. Sequeira; the following “Micros” from the New 
Forest:— Crambus perlellus, var. warringtonellus, Harpipteryx xylostella 
( harpella ), Cerostoma radiatella, Retinia pinicolana, Eupoecilia ambiguella, 
Paedisca solandriana and P. profundana. There were six specimens of 
the latter species, three of them having an inner-marginal white spot 
on the fore wings, and the other three no white spot, but a distinct 
oblique dark fascia, which gave them a strong resemblance to the genus 
Tortrix. Mr. Lane; Stauropus fagi and Lasiocarnpa quercifolia from 
Beading. Mr. Bayne; Hybernia defoliaria from Epping Forest; most 
of these were of the pale cream variety, with dark bars. 
March 6th, 1894.—Exhibits : Mr. Oldham; a short but very variable 
series of Hybernia leucophearia from Epping Forest. Mr. Clark; 
some freshly emerged specimens of Taeniocampa gothica, reared from 
eggs of var. gothicina; the specimens were richly suffused with red but 
were in other respects of the normal type. Dr. Sequeira; the Indian 
form of Vanessa atalanta and V. cardui, which did not appreciably 
differ from those found in this country; also a sort of spur from the 
thorax of Dicranura vinula with which, he stated, the moth cut its way
