usually are scattered over a forest area, undisturbed, as 

 the fruit serves to support useful animals during the time 

 that insects, caterpillars and eggs of insects cannot be 

 had. 



The various kinds of lizzards, most of the snakes, the 

 blind worms, frogs and toads are also useful animals as 

 they devour not only obnoxious insects, but many of 

 them attack also rats, mice and other small rodents. 



But even among the insects we find many which are 

 carnivorous, and feed mainly upon the smaller and 

 noxious kinds of tlieir own tribe. To this class belong 

 the following beetles : 



(1. ) The lion beetles Galasoma calidum and Calasoma 

 scrutator, of which the former hunts mostly during the 

 night, while the latter kills and eats all soft-bodied larvae 

 during the daytime. 



(2.) The elongated ground beetle, Pasimachus elonga- 

 tus, preys also upon all soft-bodied larvffi. 



(3.) The Cicindelidm are very appropriately named 

 "Tiger-beetles.'' They live in burrows, and are contin- 

 ually at the top of their burrows waiting for insects 

 which they catch and drng into their holes where they 

 eat them at leisure. 



(4.) The most widely known and justly appreciated 

 beneficial beetles are the Lady-birds, CoccinelUdce. They 

 perform the work of extermining noxious insects quietly 

 and silently, and devour countless numbers of their vic- 

 tims in a short time. 



Beetles are not the only beneficial insects ; a still larger 

 number is found among the Hymenoptera. Special 

 notice deserve : 



(1.) The dragon-fly or adderbolt-fly {Libellula), ants 

 and wasp-flies. The latter two are even in their larvae 

 state carnivorous, and prey upon other insects, devouring 

 also their eggs. 



(2.) The white faced hornets are busy all day long in
