APPARATUS USED HY ENTOMOLOGISTS. 309 



fined in a small gauze-bag, should constantly be kept, as the scent from 

 it not only tends to hasten the death of the insect, but stupifies and 

 prevents their fluttering. 



Pins. — Those used for the Oustaceaare 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. The 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 of Lepi- 

 doptera, such as the Tines, Tortrices, he. In collecting the latter, no 

 more than one specimen should l)c 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 jtrevent their rolling about, is by far the 

 safest way. 



Quills will also be found'uscful ; these must have one end care- 

 fully stopped up with cork or cement, the mouth with a cork stopper. 

 It is also advisable to tie a piece of waxed sewing silk roinid each end, 

 to prevent them from splitting : — the Entomologist may in these se- 

 cure with safety the most minute insects. 



Pocket Larv-i: Box. — This is essential in collecting for the safe 

 conveyance of Caterpillars, and is merely a cliip-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 surface, and covered with white paper. As many insects 

 require 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 

 or moved in putting the boards in, or drawing them out; this should 

 be kept in a dry place, and furnished with a door covered with fine 

 muslin to admit the air, and exclude the dust. 



Braces. — These are merely slips of card, used for confining the 

 wings of insects whilst drying, as shown in plate 3 2. 



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 larvee,) in the form represented in pi. 11.
