abruptly, without communicating with any 
other Part ; fo that unlefs it be an Inflru-

If I could have found any more of this 
Kind, fo as to have ventured killing it, by 
viewing it in the Solar Microfcope I might 
have given you a fuller Account of it, efpe- 
cially of the Inteilines : but as I was curious 
to difcover what Changes it might undergo, 
I was very tender of it; however I was dis¬

in a Week after it was gone to Pieces, fo

with a Rat's Tail, of which he has given an 
accurate Account, Mem. ii. VoL 4. of his ex¬ 
cellent Memoirs. It is it feems the Vermi¬ 
cides of a Fly with two Wings *; and if I

and Colour of the common Bee, having only two Wings : the 
Tail Part broad and flat, and., without any Sting.
