 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- 

 turingjh/ing 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
