REMARKS ON THE PRESERVATION OF 
LEPIDOPTEROUS INSECTS. 
Of all the varied tribes of insects, the lepidoptera 
are probably the most perishable. They are parti- 
cularly subject to mouldiness, and are very liable 
to the attacks of mites, and other minute insects, 
which eat into and consume their bodies. Cabinets 
should therefore be kept in very dry situations ; 
and care should be taken that the insect is perfectly 
dry when first placed in the cabinet. But when 
they do get mouldy, it may be washed off with a 
camel’s hair pencil, dipped in camphorated spirits 
of wine. After which the insect must be placed in 
a dry or warm situation till thoroughly dried, he- 
fore being returned into the cabinet. 
Each drawer should always have a piece of cam- 
phor kept in it, for the purpose of preventing the 
mites from entering, although this does not always 
prove successful. The presence of mites is easily 
known by small parcels of dust, which will usually 
be found deposited where they are. ‘They must be 
immediately picked out, and their lodgement care- 
fully cleaned with a camel hair pencil, which has 
been previously dipped in a solution of corrosive 
sublimate, and then dried. -
