58 THE NATURALIST’S GUIDE. 
aquatic species may be secured with a net ; they should 
be carefully handled, however, to avoid the sharp sting, or 
piercer, with which some of them are armed. 
Grasshoppers, Crickets, ete., or Orthoptera, —- Members cf 
this order may be found everywhere, — the grasshoppers in 
the open fields and woods, where they may be canght in 
nets. The best way to kill them is to prick them on the 
under side of the thorax with the point of a quill that 
has been dipped in a solution of oxalic acid. If they 
are not to be mounted instantly, wrap them in paper. 
Crickets may be found in the ground in holes or burrows, 
under stones, and in the grass ; a few species may be taken 
on the leaves of trees or bushes; some species of the well- 
known Cockrvach may be found in houses, and some under 
stones and bencath the bark of trees. : 
All of the above may be mounted by placing the pin 
through the thorax, and arranging the legs as before de- 
scribed. ‘The wings are also extended in the same man- 
ner as the beetles’, with the exception of the wing-coverts, 
which are fastened with cards like the wings. 
Walking-Sticks are found on low bushes or on trees, some- 
times upon the ground. They are to be put into alcohol 
to kill them, then mounted like the beetles. These in- 
sects, when dry, require delicate manipulation while being 
moved, as they are very fragile. When the colors of the 
Orthoptera ave to \ve preserved perfectly, place them in 
pure glycerine. his is especially necessary in preserving 
the larvae of grasshoppers. Cirasshoppers may be put into 
alcohol if convenient, but it must be very strony. This 
method will generally change the colors completely. Cock- 
roaches and crickets should always be killed by placing 
them in strong alcohol. 
Moths and Butterflies, or Lepidoptera, — All butterflies 
are diurnal, and are generally caught with the net. They 
may be killed by pinching the body just below the wings,
