Sire*. HYMENOPTER A. 1 8 r 



Geoffroy has only defcribcd one fpecies be- 

 longing to this genus $ to that infect he has 

 given the generical- name of Urocerus^ a name 

 taken from the point which terminates the ab- 

 domen, and which it were to be wifhed that 

 Linnseus had adopted, fince he himfelf looks 

 upon the needlefs multiplication or changement 

 of trivial names as a fault. 



Schaeffer has followed Geoffroy in the names 

 and characters of this genus. Thefe two au- 

 thors add to the Linnaean characters, that the 

 tarfi are compofed of five articulations, and 

 the under wings Ihorter than the upper 

 ones. 



The Sirex is very rare to be met with, but 

 feveral fpecies of it have been caught in Eng- 

 land. It is generally called the Tailed Waff.
