which, though really diftinct, are yet fo very nearly al- 

 lied to each other, as to be eafily regarded, on a curfory 

 view, as the fame fpecies. All the cicadas proceed from 

 eggs, which are depofited by the parent infects in and 

 about the roots of trees, near the ground : they hatch 

 into larva?, which, when grown to a certain flze, are 

 the Tettigometrze of the older writers. Thefe larva?, 

 after having continued in this ftate two years, call their 

 fkins and produce the complete infect. Fig. 3. {hews 

 the larva or Tettigometra of the cicada piebeia. I 

 fnould obferve that in our own country we have feveral 

 fpecies of this genus, which however are extremely 

 fmall, and are not diftinguiQied by any found fufficient 

 to excite attention.
