TO CORRESPONDENTS. 
Udolpho.— E nd of October and be- 
ginning of November. 
,1. D. II., Sidcot. — Pins for Rhopalo- 
erra, No. 6 and No. 8. We cannot un- 
dertake to look at boxes of insects during 
the season ; all sent to us after the be- 
ginning of April are generally discussed 
by the mites before we have found time 
to examine them. 
A. P., Harrow. — Cliickweed, dock, 
nettle or lettuce; the “little strangers” 
probably in a fortnight. 
T. L., Darlington. — The beech leaves 
sent are mined by the larva of a small 
beetle Orchestes Fagi : it is excessively 
abundant.

Preparing Dragon-flies for the Cabinet. 
— According to my experience the best 
mode of preparing the Libellulina is the 
following : — Choose a piece of thread, or 
string (according to the thickness of the 
body of the insect), and having threaded 
therewith a long needle, insert the needle 
in the end of the body at the anus itself 
(so as not to injure or destroy the anal 
appendages), and push it through till it 
comes out at the thorax between the first 
pair of legs ; then pull the thread back- 
wards and forwards two or three times 
through the body of the dragon-fly till 
the internal substance has been suffi- 
ciently removed. Finally, pull the string 
so far forward that the end of it no 
longer protrudes from the anus, and cut 
off the other end quite short between the 
fore legs. Specimens so prepared are 
durable and fine. Only in very thick- 
bodied species (such as L. depressa) is it 
necessary to open the body in order to 
remove the contents. If a species be 
sufficiently common to allow of many 
specimens being taken, we are sure to 
find that some of them keep their colours 
well without any preparation : these are 
specimens which had not long escaped 
from the pupa-state, and had not yet 
commenced their ravenous career: their
