n corolla and the grain. It takes its flation in the longitudinal fur- 

 " row of the feed, in the bottom of which it feems to fix its roftrum; 

 " probably fucks the milky juice which f wells the grain, and thus

 " moifture, occafions it to fhrink up, and become what the farmers 

 " in this part of the world call pungled, \i your correipondent in

 " that only a fmgle grain in an ear is injured by it. I have myfdf 

 " feen ears in which a fourth part of the grain was deitroyed, or 

 " materially hurt. — I have frequently fcen two of the infects upon 

 *' a fingle grain, and am told that fometimes more are obferved. 

 44 What is fingular, when I met with them on the grain in the 

 44 imago Mate, they were often in pairs, one of which was apterous. 

 44 Thefe I take to be the fexes. I once found a large fpecics am 

 44 acukalo (Thrips aculaata Muf. Kirby) in which the fame diftinc- 

 * 4 tion takes place. The larva of Thrips phyfapus is yellow, has fix 

 44 legs, which, with the antenna? and head, are black and white. 

 %i Sometimes it is all yellow. It is very nimble in its motions, and 

 " although brought away in the grain, foon makes its efcape. — 

 44 The pupa is whitifh, with black eyes, and wings apparent. It is 

 " very flow and lluggifh in its motions. The imagoit is needlefs to 

 " defcribe; it is fo like itfelf in every ftate, that it is impofiiblc to 

 " miftake it. There was an orange-coloured powder in every grain 

 " in which the infect was found, which I imagine is its excrement. 

 " All the fanners that I confulted reflecting- it agreed in faying 

 44 that it did mo ft m if chief to the late fown wheats, and that fuch 

 44 as were fown early received little or no injury. This I think vary. 

 44 probable; for when the grain is arrived at a certain degree of 

 44 hardnefs and confiftency (which perhaps was the cafe with the 

 <* early fown wheats, before the infect made any material attack),
