valuable of the Lipedopterous class, in their fly state, make* 

 this method the most eligible. 



Insects of the Coleoptera class, are found in the grub or 

 caterpillar state, (in which they are often extremely injurious 

 to the Agriculturist,) at the roots of trees and plants, or in 

 the decaying hollows of trees, and may be reared as directed 

 ,rfor the Lipedoptera, paying attention to their peculiar 

 iinds of food. This class of Insects are easily obtained in 

 itheir perfect state ; some crawl about and fly in the day 

 time, w*hile the sun shines warm, others, like the moths, only 

 appear in the evening; they inhabit a great variety of places, 

 some, the decaying hollows of trees, as the Stag Beetle, and 

 riany of the Cerambyces ; others, the dung of various 

 animals, some reside in putrid bodies, as the Sylpha 

 Vespillo ; numbers are found on tlie stems and leaves 

 oif plants, as the Scardbeus Melolontha, the Cock-Chaffer ; 

 Cbccinella^ Lady-Bird ; Chrnomelce, Curailwnes, &c. ; 

 others delight in the flowers of plants ; some abide entirely 

 in -woods, as many of the Cerambi/ces ; and they are often 

 found in considerable numbers under the bark of decaying 

 trees, some are found on the surface of stagnant waters, or 

 on the stems of aquatic plants ; others in pools, ditches, 

 ponds, and the like ; some are discoverable by the light 

 they emit, as Lampyris Noctiluca, the Glow- Worm, and a 

 vast number are to be found on dry path -ways, sandy 

 banks, and sand pits, particularly when the sun shines warm. 

 As this class of Insects are not liable to injury by being 

 carried a distance, the best mode is to have a number of com- 

 mon pill boxes, into which they may be put, and wheu the 

 collector returns home, they may be instantly destroyed.
