THE SUBSTITUTE. 
to give us tlie desired information, 
as it would not only confer a 
favour on us but would most cer- 
tainly render ‘The Substitute’ a 
paper of great importance to tbe 
young student. — T. Jones, Lower 
Road, Islington ; January 27, 
1857. 
[Small Coleoptera should be 
placed when captured in a glass 
phial with a wide mouth, contain- 
ing two or three laurel leaves cut 
into small pieces, where they 
speedily die. But as their limbs 
become rigid they should not be 
touched for a week or more, when 
all their joints will have become 
relaxed : tlien take them out, lay 
them on their backs, brush out 
their legs and antennae with a 
camel-hair pencil, turn them over, 
touch them with the tip of tbe 
handle of your pencil, previously 
wetted, to which they will adhere, 
transfer them to a card gummed 
ready to receive them, and then 
set out the legs and antennaj. The 
method of making the gum is de- 
scribed in the ‘Annual for 1855,’ 
second edition. The bottle of 
laurel leaves must of course be 
tightly corked, and it will be an 
advantage to have a stout quill 
going through the centre of the 
cork, and having a projecting 
stO])per of wood : this will obviate 
the necessity of taking out the 
cork every time you want to put in 
a small beetle. Large beetles 
may be killed by immersion in 
boiling water : they should be laid 
upon blotting-paper nntil dry, and 
then transferred to the laurel 
bottle until their limbs have be- 
come relaxed, when they may be 
gummed on to card or pinned 
through tbe right wing-case. 
Small Lepidoptera — Tortrices and 
Tinea — should be taken in pill- 
boxes, which should be placed in 
a jar, or canister having a tightly 
fitting lid, in which is a quantity 
of cut laurel leaves. The smallest 
genera, such as Nrpticula and Li- 
thocolletis, should be pinned and 
set out directly the insects are 
dead, say in half an hour; the 
others in twenty - four hours. 
Larger moths and the butterflies 
should be pierced on tbe under 
side of the thorax with a pen 
dipped in a solution of oxalic 
acid, which will kill them directly, 
and they should then be set out.] 
A Manual of British Coleop- 
tera . — I think a good Manual of 
British Coleoptera issued in parts, 
at a reasonable price, would be 
well received by entomologists 
generally, and that it would be 
well supported seems extremely 
probable, as there is nothing we 
stand so much in need of. I hope 
that it may be successfully and 
speedily carried out. — W.L. Con- 
stantine, 7, St. Andrew Street, 
Blackburn; January 26, 1857. 
W/iat's his Name — I feel 
much obliged to Mr. Proh Pudor 
for telling me how to spell Diph- 
theroides, and was not aware that 
there is another Noctua of the 
same name till he pointed it out, 
but I fear it is too late to alter it, 
otherwise I should be glad to give 
it a new name, as I think with 
him that it is very objectionable to 
have two specific names alike in 
one family. I am not acquainted 
with the German language, and 
therefore should be further obliged 
to him if he would translate his 
quotation from 'I’reitschke. Many 
of my brethren of the net are still 
in ignorance of the meaning of
