ZOOLOGY. 239 



The Cjjnips or Gall-Flk, is best taken by collecting the 

 protuberances formed by the parent lly, on different t:ind3 of 

 trees, and watching the developement of the perfect Insect. 

 The Ichneumones, may be reared by obtaining for the 

 Insects in which their eggs are deposited, as Caterpillers, 

 Spiders, dec. The Sphex resides priijcipally in flowers, and 

 about sand banks, in which it buries such insects as it 

 catches, and in them it deposits its eggs. The Chrysis, some 

 of which vie in beauty with the Diamond Beetle, is foujid 

 flying in sunny weather, about old walls, pales, posts, and 

 sand banks, in which it forms its nest. Wasps, Bees, and 

 Ants, are found on most kinds of flowers, fruits, and on 

 almost every thing that is sweet. 



There are but few places that do not produce abundance 

 of the Insects belonging to the class Diptera, as the various 

 kinds of flies and gnats; they are more paiticularly found 

 about all kinds of plants and flowers, especially umbellife- 

 rous ones, some of them are constantly flying about cattle of 

 difi'erent kinds, on the skins of which they deposit their 

 eggs, as the Oestrus, Gad-Fly ; Tabanus, &c. 



These insects may be readily killed by spirits of wine, or 

 turpentine, tiieir wings should be so expanded, that their 

 bodies become apparent and a sirall brace should be placed 

 under the body to prevent its becoraiag incurvated in drying. 



The InS;?cts in the class Aptera, are so variously disper- 

 sed, that no gv^neral instructions are necessary for their cap- 

 ture ; the Scorpion, Centipedes, Julus, &c., are found in 

 Boisoiac p'aces, as under decaying wood, stones, in damp
