 from their bafe to their middle, are folded

Geoffroy adds to the above characters of the 

 Notonecta, that it has an efcutcheon, that its 

 tarfi have two articulations, and that all the fix 

 feet are equally formed for fwimming, which 

 they appear to be in all the Linnsean fpecies,

 genus termed Corixa> with the following diftinft 

 characters :
