• The Cyntps or Gall-Flf, is best taken by collecting the 

 protuberances formed by the parent fly, on different kinds of 

 trees, and v/atchiog the developement of the perfect Insect, 

 The Ichneiimones^ may be reared by obtaining for the 

 Insects in v/hich their eggs are deposited, as Caterpillers, 

 Spiders, &c. The Sphex resides principally in ftowers, 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

 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 

 different kinds, on the skins of which they deposit their 

 eggs, as the Oestrus^ G ad-Fly ; TabamiSy &c. 



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

 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-

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

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