THE ENTOMOLOGIST'S WEEKLY INTELLIGENCER.

TO CORRESPONDENTS. 
An Etonian must forward us his name 
and address, not necessarily for publica- 
tion, but for our private satisfaction. 
T. W. is thanked for his letter. 
J. D. P. — How do your iusects de- 
cay? By mould or by mites? Camphor 
will keep away the latter, and a dryer 
situation will prevent mould. 
Maple Leaf mined dy the Larva of 
Liitiocolletis Sylvella. 
Our wood cut this week represents a 
sprig of maple, and will therefore be 
useful to some incipients in teaching 
them “ what maple is like.” The left- 
hand leaf contains a mine of Lilhocollelis 
Sylvella.

Forcing Pupce.— Last year I happened 
to have a pupa of S. Pavonia-minor, from 
a larva of 1856, and which I supposed 
would emerge about May last year, but, 
as it did not do so, I imagined it must 
be dead, so two or three weeks ago I cut 
open the cocoon, and found it, to my sur- 
prise, still alive. The idea then occurred 
to me to put it a little under the earth in 
a cucumber frame, and in two or three 
days it emerged, a fine and perfect female. 
I have since tried other pupae under the 
frame, and find it an admirable forcer for 
insects as well as plants: they get a 
moist, regular, and, at the same time, a 
natural beat. I would advise entomolo- 
gists who are fortunate enough to possess 
a frame to try it next winter: it is per- 
haps not so speedy as some former plans, 
but is certainly safer, the others appearing 
to me to be too sudden and violent. — 
W. C. Turner, 33, Bermondsey Square , 
S.E.; April 26. 
Larvce of Gnophos Pullaria . — I shall 
be particularly obliged to any of your 
correspondents who will forward me a 
few larvte of this insect: l have some 
from W ales, and wish to compare them 
with southern species. They abound, 
I believe, near Lewes. — Captain Cox, 
Fordwich House, Fordwich ; April 28. 
Coleophora Alcyonipennella. — I have 
found these larva; plentifully on Cen- 
laurea nigra, and shall be happy to sup- 
ply any one in want of them, if they will 
send a box and stamps for return post- 
age. — William Winter, Ranworth, 
Blofield, Norfolk ; May 3. 
Nepticula Agrimonice. — I think the 
following notice will rather surprise your 
readers. You are already aware that the 
Nepticula larva which 1 found here on 
Agrimonia Eupatoria has produced N,
