must consequently die, which but too frequently happens from 
mismanagement. 
Some seasons are more favourable than others for the pro- 
duction of Caterpillars, and to keep each kind by themselves 
would require an immense number of cages, as well as occupy 
much time in changing the food, and paying due attention to 
them. ‘To obviate this, some persons have large breeding ca- 
ges, with a variety of food in them, which must be cleaned 
out every two days, and fresh leaves given to the catérpillars ; 
as, on due attention to feeding, the beauty and vigour of the 
coming insects will much depend. 
The Larvz of insects, which feed beneath the surface of 
the earth, may be bred in the following manner: Let any box, 
that is about three or four feet square, and two or three feet 
deep, be lined internally with tin, and a number of very 
minute holes be bored through the sides and bottom. Put 
into this box a quantity of earth, replete with such vegetables 
as the Caterpillars subsist on, and sink it into a bed of earth, 
so that the surface may be exposed to the different changes of 
the weather. The lid should be covered with brass or iron 
net-work, to prevent their escape, and for the free admission 
of air. 
CasineTt.—Such is the advanced state of Entomological 
science, that a collection of British Insects requires a cabinet 
of from 50 to 100 drawers, which are generally about fourteen | 
or fifteen inches in length, and eighteen in breadth, and about | 
_two inches deep, The bottoms should be lined with cork, of 
about the sixth of an inch in thickness. It must be chosen as 
free from cracks and knots as possible. Each drawer must 
have a lid of glass, with an edge of wood very nicely fitted, so 
as to prevent, as much as possible, the admission of air or dust. | 
This lid must rest on a rabbit. 
The young Entomologist should obtain a cabinet of about 
| thirty drawers, arranged in two tiers, and covered in with 
folding doors. There is a great convenience in this size, as the 
cabinet is rendered more portable, and at the same time ad- 
mits of having another of the same size, being placed above the 
top of it, as the collection increases, without injuring the uni- 
formity, and thus the drawers may be augmented to any 
extent. It is immaterial whether the cabinet is made of ma
