INSECTS. G7 
used for capturing Aquatic Insects, which are either lurking 
at the bottom, swimming 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 handie, may be made of such dimensions, as 
will answer the second joint of the Entomological net-rod, 
which will save carrying ancther handle ; or a walking-stick 
may be made to fit it. 
A Purat, 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 at the 
surface. 
A Dicerr, 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 
pupz of Lepidopterous Insects, at the roots and in the clefts 
of the bark of trees; and also for pulling of the bark, particu- 
larly from decayed trees, under which many curious and rare 
_ insects are frequently found. It is most useful with an arrow- 
headed point. 
Settina NEEDLES, plate IV. fig. 12. 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. 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- 
_ 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 antenne and palpi of insects of the minute kinds. 
Brass Purers, plate IV. fig. 14. These are used 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 vet free and not set up.
