Colias Eclusa hybemating . — On the 
24th of February last I was out pupa- 
hunting, and on pulling down some 
thick ivy from an old wall I discovered a 
very good specimen of Colias Edusa in 
an interstice in the wall : when it had 
been in a warm room for two or three 
hours it revived a little and crawled 
about : it is now in my collection. —

Forcing Pupae . — The readers of ‘ The 
Substitute’ may have observed a short 
notice from me on this subject. The fol- 
lowing results have attended my method 
this spring. I have bred, within the 
last three weeks of March, 2 S. Carpini, 
14 E. Centaurearia, l E. Coronaria, 12 
C. Ferrugaria , 1 M. Lituraria, 5 C. Cur- 
tula, 1 N. Dromedarius, 2 N. Trepida, 1 
N. Dodoncea, 1 N. Cluwnia, 1 N. Cucul- 
lina, 1 N. Dictcea, 1 A. Megacephala, 
2 A. Menganthedis, 2 N. Camelina, 1 Y. 
Irnpluviaria, 6 B. Piniaria. The insects 
which appear in the ordinary course of 
nature at this season I have, of course, 
omitted. Two objections to the forcing 
system have been made to me by friends : 
first, that it tends to cripple, and second, 
that forced specimens are paler in colour. 
My experience satisfies me that there is 
not the slightest foundation for either of 
these objections. Not a single specimen 
of the insects enumerated above is, in the 
least degree, paler than usual. The pair 
of Palpina and the two female Trepida. 
are, by far, the finest I ever saw. The 
two Carpini were a little crippled in the 
under wings, a circumstance, however, 
which constantly occurs in that species. 
With this exception all, even the Little 
Pugs, were in the most perfect condition. 
I consider this discovery, or system, or 
whatever it may be called, of the utmost 
value, as the collector is thus enabled to 
set his insects in the early spring months, 
and commence the season with undis- 
turbed mind and unshackled hands. 
Thus, too, I hope to be able to supply 
(as far as is in my power) my corres- 
pondents with the insects promised last 
autumn, six weeks or two months earlier 
than would otherwise have been the case.

Forcing Pupae. — I have lately beeu 
breeding Lithocolletis alnifoliella and 
pomifoliella, and many of the Taenio- 
campce. I must tell you the reason of 
my having them out so early: I have 
forced them, that is, I put them into our 
hothouse, where it ranges about 60° by 
night and 75° by day. I first removed 
them into a greenhouse, and let them 
remain there for a week or ten days to 
imitate spring, and then removed them 
into the hothouse, where it is sximmer, so 
by this means I shall be able to get most 
of my r breeding cages at liberty by the 
time they are wanted again ; besides it 
saves so much time, which is a very 
precious article in the busy collecting 
season. — E. Parfixt, 4, Weir field Place,

Coleophora juncicolella. — Having re- 
ceived some specimens of this insect in 
the larva state from Frankf'ort-on-the 
Maine, I had learnt what to look for, and 
accordingly visited the heath-field at 
West Wickham Wood for the purpose of 
obtaining a supply. I found them very 
plentiful, though hard to find from the 
smallness of the cases and their resent-
