florets which produced this little plant ; but fome ears of a kind of 
bearded wheat, which I cultivated in my garden, were quite dif-

infects that are found in wheat, the Thrips phy/apus, in all its 
ftates, is by far the moft numerous. I do not recolle&t examining a 
fingle ear in which it was not to be found; and my opinion: ftill

nor can I look upon the fpecies of this genus as carnivorous, any 
more than thofe which belong to its neighbouring genera, 4phis, 
Chermes, and Coccus.
