INSECTS. 61 



Another method is to spread a large table-cloth under trees 

 and bushes, and then beat them with a stick. An umbrella re- 

 versed has frequently been used for the same purpose. Bose, the 

 celebrated naturalist, used this last method — he held the umbrella 

 in the left hand, while he beat the bushes with the other. 



The Hoop or Aquatic Net, fig. 2G. — This net is used for 

 capturing Aquatic Insects, which are either lurking at the bottom, 

 swimming through the liquid element, or adhering to plants. It 

 may also be successfully used in sweeping amongst grass and low 

 herbage, for Coleopterous Insects, and others which are generally 

 to be found in such situations. The socket, for the handle, may 

 be made of such dimensions as will answer the second joint of 

 the Entomological net-rod, which will save carrying another 

 handle ; or a walking-stick may be made to fit it. 



A Phial, fig. 33. — This may either be made of tin or crystal, 

 and used for collecting Coleopterous and other Creeping Insects. 

 The mouth should be nearly an inch wide, and a cork exactly fit- 

 ted to it, in the centre of which must be inserted a small quill, to 

 afford air, and inserted about an inch beyond the cork, to prevent 

 the insects from escaping. If the bottle is made of tin, and of t 

 larger size, a tin tube must be introduced into its side, and ter- 

 minating externally at the surface. 



A Digger, fig. 28. — The instrument is either made of iron or 

 steel, and is about six or seven inches in length, fixed into a turned 

 wooden handle. It is used for collecting the pupse of Lepidopter- 

 ous Insects, at the roots and in the clefts "of the bark of trees ; and 

 also for pulling off the bark, particularly from decayed trees, 

 under which many curious and rare insects are frequently found. 

 It is most useful with an arrow-headed point. 



Setting Needles, fig. 29. — Fitted into a small wooden handle, 

 the needle itself should be about three inches long, and about the 

 thickness of a small darning-needle, slightly bent from about the 

 middle. Fig. 30 is a straight needle, which is used for extending 

 the parts of insects ; at one end of the handle is the needle, and 

 at the other a camel-hair pencil, which is used for removing any 

 dirt or dust which may be on the insects. The pencil may be 

 occasionally drawn through the lips, brought to a fine point, and 

 used for disposing the antennae and palpi of insects of the minute 

 kinds.
