GENERA. 



TN the preceding pages, I hop6, I have made it 

 •*■ evident, that the characters at present in use to 

 distinguish those insects, which Linneus considered 

 as Jlpes, whether we follow his system or that of 

 Fabricius, are not universally applicable to them : 

 I shall, therefore, now proceed to offer my own 

 ideas upon the subject, and to point out such 

 characters as will most constantly distinguish the 

 species they are designed to denote ; which a close 

 and frequent examination of the external parts of 

 many individuals has enabled me to discover. But 

 in order to prevent tautology, when I am drawing 

 out the Natural Characters of my genera and 

 families, that I may exclude from them such cir- 

 cumstances as appear to be common to all Hyme- 

 nopterous insects, I shall previously attempt giving 

 one of the Hymenoptera class.
