226 Mr, M aksh am' s further Obfervatlons on the Wheat I 



that I have not had any fuccefs in difcovering the perfect flat 

 this infect : however, I will relate exactly what has happen 



" I inclofed feveral ears of wheat, containing a number of the 

 fmall yellow larva?, in a flower-pot, clofely flopped at the bottom, 

 and covered with gauze at the top; and have at different times found 

 dead, at the bottom of the pot, two different forts of very {mail flies, 

 one of which was a fhort thick black fly, with very long trani parent 

 wings, and long {lender fmooth antennas, of which I have fent two

 flate ; and I hate alio inclofed fuck figures as I was able to make of 

 them, fee Tab. xix. No. vi. fig. 2, a and b. To your learned friend's 

 queftion as to the quantity of mifchief done by this unknown fly, ,1.

 of two grains in each ear deftroyed by this infect not too great, for I 

 fcarcely examined any ears in which there were not more than that 

 injured. But, after all, are not our fears with refpect to the injury 

 that the wheat has received from; this infect greater than they 

 ought to be ? and does not the wheat fufFer as much from infects 

 or fome other caufe every year, even in thofe years that are mofl 

 productive ? 



" By what I can learn from enquiries, and from my own obferva- 

 tion, there is a good crop of wheat in this neighbourhood: one farmer, 

 who has begun to threih out his wheat, has found it yield well ; 

 ajid when in my own field I had the curiofity to rub out a few ears,
