LETTER XXXIV. 



"To the same. 



SELBORNE, March 30^, 1771. 



SIR, There is an insect with us, especially 

 on chalky districts, which is very troublesome 

 and teasing all the latter end of the summer, 

 getting into people's skins, especially those of 

 women and children, and raising tumours which 

 itch intolerably. This animal (which we call an 

 harvest bug) is very minute, scarce discernible to 

 the naked eye ; of a bright scarlet colour, and of the genus of 

 Acarus. They are to be met with in gardens on kidney-beans, or 

 any legumens, but prevail only in the hot months of summer.
