THE ENTOiVIOLOGIST’S WEEKLY INTELLIGENCER.

I saw it three weeks after its capture, 
and I must say I cannot see the force of 
the argument that admits Calephia Al- 
chymista and others on the authority of 
a single specimen being captured, when 
here is both male and female Opassina 
taken, and the latter specimen of Mr. 
West’s in a situation a great deal less 
likely for either being imported in pupa 
or having flown to light, as in the case 
of C. Alchymista. Chorley does not, 
aboie all other places, possess any attrac- 
tion by light, and yet some twenty-five 
miles from a port; the canal is chiefly 
coal traffic, i cannot see a reason why 
England should not possess a genus 
distinct from those known as European 
as well as Indian : there is plenty of 
room in this island for species as large 
and as conspicuous as Pandesma to 
have escaped detection. — J. B. Hodg-

A Corticivorous Larva.. — Last autumn 
I beat three or four young larvae of 
Metrocampa Margaritata from oaks, on 
the leaves of which they fed and grew 
until the oak-foliage began to wither and 
fall; when, supposing they had given 
over eating till sometime in the coming 
spring, I put them out-doors on a small 
seedling oak enclosed in a glass cylinder, 
and left them to themselves. During 
the partial thaw which occurred on the 
30th of December, I was looking to see 
how my hybernating larvte had borne the 
hard weather, when, to my surprise, I 
found that these Emeralds had not only 
eaten all the buds of their oak-plant, but 
had also gnawed off all the tender bark 
of the young shoots. I then removed 
them in-doors and supplied them with 
oak-twigs, on the bark of which — not 
touching the buds at all — they continue 
to feed and thrive. I have known the 
larvae of Eupithecia Vulgata eat withered 
whitethorn leaves, and those of Acidalia 
Bisetata and Incanaria withered dande- 
lion, apparently from choice, as the fresh 
green food was as close to them as the 
dry, and I have been told of some small 
looper, which — more choice even than 
Mr. Burney’s blackberry-eating Eupi- 
thecia Coronata — was found feeding on 
raspberries, but I do not remember to 
have met with any instance of a bark- 
ealing Macro before, though doubtless 
others have made similar observations. — 
Q. 
Selenia illustraria treble-brooded. — On 
the 21st of last May, Mr.R. H. Fremlin, 
of Wateringbury, very kindly supplied 
me with a few eggs of S. illustraria, 
which had been laid but a short time 
previously to my receiving them : hatch- 
ing commenced almost immediately, and 
the larvte fed well and vigorously, not- 
withstanding the cold and rainy weather 
so much complained of as being so de- 
structive, even to in-door broods. They 
began to enclose themselves in the birch- 
leaves, upon which they had been feeding, 
on the 22nd of June, and had all spun 
up in the course of a few days. From 
the 9th to the 15th of July the imagos 
had all emerged. I had eggs from two 
females on the lllh of July, and within 
ten days these also began to hatch, and 
upon the 26th of August a few began to 
spin up. Upon the 8lh and 10th of the 
following month (September) two very 
fine female moths emerged, thus making 
three broods in one season. Unfor- 
tunately no males appeared, or I should 
much liked to have paired them, and 
endeavoured to get another lot of eggs, 
in order to ascertain if they would re- 
main over the winter and hatch in the 
ensuing spring. The majority of the 
remaining larvae continued feeding up- 
wards of three weeks after the appearance 
of the perfect insects, and the last dozen 
of them did not spin up to undergo their 
pupal change until the 17th of October 
following. Judging from the size of 
some of the larvae, from having fed so 
long, I shall expect some prodigiously 
fine specimens early in the spring. The 
larvae were all kept in-doors, and were
