gerous affair. I was therefore compelled 
to clay up the hole. In the morning 
I succeeded, after a fresh dose of chloro- 
form, in enlarging the hole sufficiently, 
and got the comb out. It was circular, 
composed of hexagonal cells, to the num- 
ber of thirty, with their mouths down- 
wards, the side of each cell measuring 
about four lines; at the top a stout ap- 
pendage allowed of its being suspended. 
Over these cells, and reaching about an 
inch below them, was hung a cup, the 
top of which was attached in various 
places to the tree: this cup was as thin 
as paper, white, with several darker lines 
running round it. The centre cells con- 
tained larvae in an advanced stage of 
growth, the intermediate ones younger 
larvte, and the marginal ones eggs. The 
eggs were white, loiigish oval, about one 
line in length, and attached to the bottom 
of the cell by one end. Not being able 
to induce the hornets which I caught, to 
the number of six, to remain with the 
comb, it is now in my cabinet. — Richaed

OBSEKVATIONS. 
Observations at Tamivorth. — I observed 
Miana Literosa at the flowers of the 
snowberry tree, about the end of last 
mouth or beginning of the present one, 
and I captured two specimens : hoping 
to discover the larva, I tried to get its 
eggs, but it was of no avail. Two speci- 
mens of Bornbus Harrisellus have been 
taken here within the last few days, by 
Mr. M‘Laren, a lepidopterist, in this 
town, and he kindly added them to my 
collection. B. Subterraneus, although 
common in many southern localities, has 
not occurred here, as I'ar as I know ; and 
if the one occurs without the other, does 
it not go far to prove that each is a dis- 
tinct species? Mr. Unwin seems to have 
a similar opinion. — F. O.Euspini, Tam- 
worth; August 12. PS. I am afraid 
that in my last communication I wrote 
my name very unintelligibly, as it was 
misprinted “ H. Ruspini.” — F. O. R. 
EXCHANGE. 
Exchange. — I have duplicates of the 
following . — 
Liparis Monacha, 
Xylophasia Scolopacina, 
Apamea Connexa (100), 
Noctua Brunnea, 
Cosmia Trapezina, 
Polia Chi, 
Ajilecta Herbida, 
... Nebulosa, 
for which I shall be glad to receive 
offers of fertilized ova, pupa or good 
images. I have also a few batches of 
ova of L. Dispar, which I shall be glad 
to give to any entomologist wanting 
them. — B. Gibson, Almshouse Lane, 
Wakefield ; August 10. 
REMARKS ON THE SUPPOSED IN- 
FLUENCE OF THE FOOD OF THE 
LARViE IN CAUSING VARIATIONS 
IN LEPIDOPTERA. 
BY R. M'LACHLAN. 
[Read at the Meeting of the Entomological Society, 
July 1, 1861.] 
The natural history of Coleophora oliv. 
aceella appears to have some bearing 
on the question so often asked at our 
meetings, “ Are not many of the so-called 
species of Micro-Lepidoptera merely mo- 
difications of one or more previously 
described species produced by the larvcB 
having fed on different plants?” It ap- 
pears to me that, as has often been said 
before, this question would never have
