 VATIONS SUGGESTED BY THE SUBJECT. 



I NOW proceed to the treatment and description of the 

 genera severally, and the enumeration of the species in 

 due scientific consecutive order. 



The generic names adopted are those of the first 

 describers of the genera; hut the generic characters 

 given by them could not be employed, they having been 

 usually framed to suit special purposes. 



All the generic characters introduced into this work 

 are therefore quite original, and have been made from 

 a very careful autoptical examination of the insects 

 themselves.

 to the species described in Mr. Kirby's work, where he 

 is not the first describer, or to those of such other 

 English works wherein the species may have been de- 

 scribed in ignorance of its previous registration. 



The observations appended, wherein the habits of the 

 insects are described, will be found to embrace discur-
