INSECTS. 77 



used for capturing Aquatic Insects, which are either lurking 

 at the bottom, swimming 1 through the liquid element, or ad- 

 hering 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 Ppi^. plate IV. fig. 11. 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 fitted 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 a larger size, a tin tube must be 

 introduced into its side, and terminating externally 

 surface. ^^ bu** ^ wRS* 2 



A PjfifrER. plate IV. fig-. 13. This 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 

 pupae of Lepidopterous Insects, at the roots and in the clefts 

 i the bark of trees ; and also for pulling off the bark, particu- 

 from decayed trees, under which many curious and rare 

 insects are frequently found. It is most useful with an arrow- 

 headed point. 



SETTING NRF.m.F.gj. plate IV. fig. 12. Fitted into a small 

 wooden handle, the needle itself should be about three inches A 

 long, and about the thickness of a small eta>imug=iiegdle 

 slightly bent from about the middle. Fig. 16. 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- 

 Jiair 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 antennas and palpi of insects of the minute kinds. 



BRASS PLIERS^ plate IV. fig. 14<. These are ased for 

 picking up small insects from the roots of grass, &c. They 

 may also be used for laying hold of small insects, while they 

 are yet free and not set up.
