The genera into wliich our author, after Fabri- 

 cius, has divided ^/»z,y are arranged under his tenth 

 and eleventh families. The characters of the first 

 of these families belong to those insects which I 

 liave considered as constitutins; one 2:enus under 

 tlie name Melitta, those of the other as peculiar 

 to genuine Apes. They are both drawn up, with 

 very great accuracy, in the following terms.
