THE SUBSTITUTE. 
important thiup; to Aicilitate ex- 
changin<T is to return any box re- 
ceived by next post if possible. 
Now many of my correspondents 
suffer at the present moment from 
this cause alone. It persons re- 
tain your boxes from three to six 
weeks, bow by all that s slow 
can we get along. Therefore re- 
member to “Relurn Boxes per 
Return.” — E. S. Nokcombe,

CAPTURES. 
PhlogopJiora Einpyrta, — I am 
pleased to communicate the infor- 
mation to the readers of ‘ The 
Substitute’ that on the 14th iiisl.

Fertile Eggs from single Female 
Insects. — I have been engaged for 
some time past in investigating 
the h’stoiy of Daphnia Schtejf 'eri, 
an animal the hmale of which 
produces fertile eggs even when 
kept separate from the male, and 
I write to you to solicit from the 
numerous entomologists, who will 
1 know see this letter if yon kindly 
insert it in ‘The Substitute,’ the 
details of any similar facts which 
may have occurred to them in the 
course of their observations : not 
only in the Aphides and Cyni- 
pidft, but also in the moths, I be- 
lieve such instances not very tin- 
frequently occur. Jourdan has 
jiublished several, and 1 shall feel 
greatly obliged to any entomolo- 
gist who will forward to me any 
similar observations. Permission 
to publish would enhance the ob- 
ligation. — John Lubdock, High 
Elms, Famborovgh, Kent; No- 
vember 8, 1856. 
[We shall be happy to pnblish 
any communications on this very 
interesting and obscure subject.] 
The Lancashire Collectors. — 
Did you ever read such nonsense 
as Mr. Gregson’s in the ‘Zoolo- 
gist?’ I have no time for contro- 
versy, but surely he invited “ a 
setting down” by some old col- 
lector, and it is hardly fair of the 
editor not to allow’ him to have it. 
Can you translate his Latin, — 
what is “ 7 iigrifoldella P” Stark, 
staring nonsense! Compare onr 
dog-latin with the beautiful classic 
of Zetterstedt and see how refresh- 
ing it is to the scholar after the 
trash we print in England ; or 
look to the beautiful introduction 
to Mar.sham, by the Bishop of 
Carli.sle, and think of the T.iatin of 
this time. PROH PUDOR! 
Jlybernating Larvie and Pupa. 
— Can any one tell me where the 
cocoons of those Bombyces which 
pass the winter in the pupa state 
are to be found. Eriogaster La- 
nestris must always pass the win- 
ter as a pupa. The larvai of 
Lnsiocampa Quercus, Trifolii and 
Rubi, are said to hybernate, yet 
all the larva? of L. Quercus that I 
have ever had sptiu up in the 
autumn, passing the winter as 
ptipa; ; jirobably Trifolii and Rubi 
sometimes do the same, and very 
likely Gastropacha Hid folia, yet 
I never heard of the pujia) being 
found. Saturuia Jhivonia-minor 
we know attaches its cocoon to 
heath or other jilants. Do others 
do the same? But even sup- 
posing that the larvae hybernate 
they must surely be pretty well
