tion, the bag-net just described is preferable. 
4. Scarcely any implement seems a greater favourite 
with British collectors than what may be called thejly- 
net*. This is universally employed by them for cap- 
turing flying insects, especially Lepidoptera. It is simi- 
lar to what is called a bat-fowling net, and should be 
made of green or white gauze or coarse muslin. The 
former colour, as being less visible, is most proper for 
mothing in the night; but the latter is best for the day, 
as this net is useful to hold under the branches of trees 
and shrubs to receive the insects that fall when they are 
beaten. The rods for the net we are considering, — which 
should be about five feet long, half an inch in diameter 
at the base, and gradually tapering to the end, — must be 
made of some tough wood ; each should consist of about 
four joints for the convenience of carriage, and each 
joint should be fitted with a socket at the lower ex- 
tremity, to receive the top of the joint below it : the ter- 
minal joint must either be bent into a curve, or fitted 
with an angular socket or ferrule, so as to form an ob- 
tuse angle with the rest of the rod b . The gauze which is 
to form the net, being cut into the requisite shape, should 
be welted round, except at the bottom, where it should 
have a deep fold or a bag for preventing the escape of 
the included insects — in order to form a slide for the 
rods to slip in. At the apex where they meet, a few 
stitches should be set, or a piece of leather sewed in, to 
prevent their going too far. At the bottom, on each 
side, two strings must be sewed on the net, to receive
