124. young turnep-plants, and foon found my ex- 

 TENTHREDO pectation gratified in the fulleft extent ; for 

 THETURXEP the plants being fucculent and tender (the 

 rough leaves about an inch in diameter > and the 

 feedling- leaves fliil remaining), they imme- 

 diately began to depofit their eggs. I had put 

 the glafs over them, left they fliould fly away ; 

 but this was unneceflary : I therefore took it 

 off, and made my obfervations without re- 

 ftraint. The leaves were thin and tranfparent ; 

 the fun fhone full upon them ; and the flies 

 were fo tame that I could obferve the opera- 

 tion in any point of view I pleafed : even 

 touching them gently while in the act did not 

 difturb them. I faw not lefs than twelve or 

 fifteen depofits ; and Mr. Robert Bartram call- 

 ing upon bufmefs, while I was obferving them, 

 alfo law three or four. 



I put them upon the plants between nine 

 and ten o'clock in the morning ; and leaving 

 them between ten and eleven, did not return 

 until pafl one, when I found them ftill bufy 

 in the act of depofiting. My worthy and 

 fenfible friend, Mr. Parkinfon, calling at that 

 time, obferved two or three operations. They 

 ,. foon afterwards, however, began to droop, and 

 entirely left the plants. 



I have now no longer any doubt as to the 



opera"
