APPARATUS USED BY ENTOMOLOGISTS.

feed in a small gauze-bag, should constantly be kept, as the scent from 
‘t not only tends to hasten the death of the insect, but stupifies and 
prevents their fluttering. 
Pins.— T hose used for the Crustacea are generally large, some being 
four inches in length ;— the size of the pin should correspond with the 
size of the animal. Those used for insects are of two sizes, small lace, 
and a much finer made only for this purpose. 1 he pins used for set- 
ting should be longer than those used for piercing the insects, and 
will be found much more convenient. 
Pill Boxes.— Of these the Entomologist should possess three or 
four dozen : — they are generally used for the smaller species ot Lepi- 
doptera, such as the Tinese, Tortrices, &c. In collecting file latter, no 
more than one specimen shotdd be inclosed ; and such boxes as con- 
tain them require some care in carrying, to prevent the insect being 
shaken, which would injure the wings : carrying them in the hat, with 
a handkerchief over them, to prevent their rolling about, is by tar the 
safest way. 
Quills will also be found useful; these must have one end care- 
fully stopped up with cork or cement, the mouth with a cork stopper, 
ft is also advisable to tie a piece of waxed sewing silk round each end, 
to prevent them from splitting: — the Entomologist may in these se- 
cure with safety the most minute insects. 
Pocket Larvit. Box. — This is essential in collecting for the safe 
conveyance of Caterpillars, and is merely a chip-box, with a piece cut 
out of the top and bottom, and covered with gauze, for the free ad- 
mission of air: a few leaves of the plants on which the caterpillars 
are found must be put in the box with them. Further instruction for 
the method of breeding insects is given below, 
Setting Boards.— These are simply a thin deal board of a conve- 
nient size, and covered with soft cork. The cork must be perfectly 
even on the surtace, and covered with white paper. As many insects 
tequire much time in drying, I should recommend the Entomologist 
to have a small box of about a foot square, with slips of wood nailed 
on the inside for the boards to slide on, and at the same time at a 
sufficient distance from each other, that the pins may not be displaced 
°r moved in putting the boards in, or drawing them out; this should 
tie kept in a dry place, and furnished with a door covered with tine 
muslin to admit the air, and exclude the dust. 
Braces.— T hese are merely slips of card, used for confining the 
wings of insects whilst drying, as shown in plate 12. 
Breeding Cages are used for rearing insects from Caterpillars, and 
may be made of wainscot, (deal is objectionable, as the scent from the 
turpentine is liable to kill the larvae,) in the form represented in pi. 11.
