tured many species in wooded districts during the even- 

 ing, when they were flying from one piece of woodland 

 to another. They occur in various species of trees, to 

 which the larvae do much damage by boring into them. 

 Many species are also found on flowers in autumn. 



CHRTSOMELID^;, Leaf-Beetles. These Beetles are 

 found on leaves and flowers of plants. They may be 

 collected by beating with a stout net. The infamous 

 Potato-Beetle is an example. The larvaB occur on 

 plants. 



COCCINELLID^:, Lady-Birds. These well-known 

 Beetles are found on plants and trees. 



Hemiptera, Bugs. The well-known Ciccadia be- 

 longs to this order. They may be captured with the 

 net. Many species of this order may be taken by 

 beating shrubbery with a stout net. 



Orthoptera, Grasshoppers, etc. I now kill mem- 

 bers of this order with the fumes of benzine. They 

 should be placed in a close box which is partly filled 

 with cotton cloth which has been saturated with ben- 

 zine. In pinning, I now double up the legs of the larger 

 species. 



GRYLLID.E, Crickets. They may be found under 

 stones, pieces of wood, etc., or in open fields. The 

 Mole-Cricket occurs beneath the ground, in damp lo- 

 calities. Its hiding-place may be detected by its song- 

 notes. 



LOCUSTEAI^I, Grasshoppers. The collector should 

 learn to distinguish members of this family by the 

 song. Some sing only at night, and may thus be cap- 

 tured with a light. They are always found on grass, 

 trees, or plants, and by carefully approaching them, 

 they may be taken in a net or with the hand. Some 

 species which inhabit high trees, like the Katy-did 

 (Cyrtophyllus concavus] are difficult to procure. The
