96 rSeptember, 1866. 
Note on Bombyx quercds. — A few days since I saw a B. quereHs emerge, and on 
testing a fluid observed on the head, I found it gave a decided alkaline reaction to 
litmus-paper. This alkaline fluid may probably account for the easy exit of moths 
through such tough things as some cocoons are. — Id. 
Entomological Society of London. 6th August, 1866. — Prof. Westwood, 
M.A., F.L.S., Vice-President, in the Chair. 
It was proposed by Mr. Pascoe, seconded by Mr. Stevens, and carried by 
acclamation, that the cordial thanks of the Society be given to W. Wilson Saunders, 
Esq., for his entertainment at Reigate on the 6th ult. 
Mr. Stevens exhibited a collection of insects of all orders, sent from Bahia by 
Mr. Reed, including some fine Cicindelidce, ^c. He also exhibited species of the 
genus Pogonostoma, collected in Madagascar by Mr. Gerrard, and some Cetoniadoe 
from Sierra Leone. 
Mr. D'Orville sent for exhibition an example of Cahera pusaria (male) with the 
wings entirely of a silky lead colour, the body retaining its ordinary white appear- 
ance ; this had been captured in his own garden at Alphington, near Exeter. 
Mr. Bond exhibited a series of Eudorea hasistrigalis, Knaggs (Ent. Mo. Mag., 
vol. 3, p. 1), and some remarkable varieties of E. amhigualis from Mr. Barrett, of 
Haslemere ; also examples of the rare Catoptria microgrammana taken by Mr. Meek 
at Folkestone, atid two specimens of the hitherto unique Sericoris euphorhiana 
also taken by Mr. Meek at the same locality. 
Mr. McLachlan exhibited a collection of cases of caddis-flies recently received 
from Bavaria and Basle (those from the latter locality given to him by Mr. A. 
Miiller) ; including some remarkable forms of the case of Halesus digitatus ; that of 
Enoicyla pusillcu (of which the larva Uves out of the water) ; and a singular case 
(of uncertain genus, possibly Brachycentrus,) formed of vegetable matters neatly 
arranged transversely, so as to form a partially angular tube, closed by a solid 
operculum, in the centre of which are four small holes to admit the water ; &c., &c. 
Mr. Janson exhibited a box of rare British Coleoptera taken by Charles Turner 
in the New Forest, including two fine examples of Velleius dilatatus which had been 
found in the burrows of Cossiis ligniperda. 
Professor Westwood mentioned that having at the last meeting expressed an 
opinion that the singular insect then described by Mr. Pascoe under the name of 
Ectrephes formicarum might pertain to the Paussidoe, he had since examined the 
parts of the mouth, and had arrived at the conclusion that it had no relationship 
with that family, and was, in fact, of doubtful location. He also read an extract 
from the Journal of the Society of Arts respecting the recent swarms of locusts in 
Algeria, they having prevailed to such an extent as to cause a famine, the water- 
courses being blocked up with their dead bodies, and the mihtary having been 
employed to mitigate the bad efi'ects by clearing them away. With respect to the 
.4il(mt^s silkworm (lttocusCywt?iia), he remarked that hesawnoprospect of obtaining 
a second brood this season from those reared by him. 
It was announced that the next (September) meeting would be the last held 
in the rooms now occupied by the Society ; that after then it would meet in the 
apartments of the Linnean Society at Burlington House ; due notice would be 
given of the necessary alterations of the days of meeting, &c.
