be needed. These can be purchased from the shop of any Natural 

 History dealer at about 3^. per dozen, nested (in four sizes). 



For collecting aquatic insects and their lar'ocz we shall require a 

 water net, made of fine zinc-gauze, about six inches in diameter, 

 to group about among stones and other rubbish at the bottom of 

 pools and ditches. This instrument should be made so as to 

 slip on and off a walking-stick when required. 



A killing bottle charged with cyanide of potassium or with 

 chopped laurel leaves completes the outfit. 



Little need be said as regards the mode of collecting insects, 

 as their habits may be gathered frc m the following pages. 



They may be found almost everywhere, in woods, fields, gar- 

 dens, in pools, ditches, canals, and rivers, under dead leaves and 

 the bark of trees, among moss and stones, etc., etc. They may 

 also be found at all times of the year; even in the depth of 

 winter some species may be met with. 



Most insects may be preserved in the same manner as Butter- 

 flies and Moths. They should be set on flat setting-boards, and 

 left to dry thoroughly before being removed. 



The smaller species may be gummed to cardboard in a similar 

 way to Beetles. 



In the arrangement of the insects in the cabinet the classifica- 

 tion and order given in these pages may be followed. About 

 half-a-dozen of each species will be found a convenient number to 

 collect.
