ZOOLOGY. 239 



The Ci/nips or Gall-Flf, is best taken by collecting the 

 protuberances formed by the parent fly, on different kinds of 

 frees, and watching the developement of the perfect Insect. 

 The Ichneumo7ies, may be reared by obtaining for the 

 Insects in which their eggs are deposited, as Caterpillers, 

 Spiders, &c. The Sphex resides principally 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 found 

 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 Dipiera, as the various 

 kinds of flies and gnats; they are more particularly found 

 about all kinds of plants and flowers, especially umbellife- 

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

 different 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, their wings should be so expanded, that their 

 bodies become apparent and a small brace should be placed 

 under the body to prevent its becoming incurvated in drying. 



The Insects in the class Aptera, are so variously disper- 

 sed, that no general instructions are necessary for their cap- 

 ture ; the Scorpion, Centipedes, Julus, «fec., are found in 

 noisome places, as under decaying wood, stones, in damp
