that in like manner as the maggots in the glafs tube quitted the wheat, 

 and lodged themfelves in the ftoppers, i'o in the granary they con- 

 cealed themfelves in the linings and beams, until their transforma- 

 tion into flying inledls fliould be compleated. And I was confirmed 

 in this opinion by obferving the granary to have been fo perforated, 

 or eaten into by thefe maggots, that not a fingers breadth was left 

 untouched by them. 



I alfo obferved tliat great part of the Hopper which was within 

 the glafs tube, was gnawed or reduced to powder, and many cliinks 

 or crannies formed in it, and though the maggots endeavoured to 

 conceal themfelves within the ftopper, yet three of them remained 

 in the glafs, in which they lay quiet the whole winter, and they

 efcaped through the holes perforated by them in the box. 



On the 23d of May, the aurelias before mentioned, had become of 

 a red colour, and the next day I faw a flying infe61, which is called a 

 Moth, fluttering about the glafs tube. This had proceeded from one 

 of the aurelias, which liad been the chief fubje6l of my obfervations, 

 and I law lying near it, a pellicle, or little fkin, which had been the 

 cafe or fheath in its aurelia ftate. 



Two days before difcovering this moth, I had obferved feveral of 

 the fame winged infefts flying about my fiudy, two of which I killed, 

 and upon examining them by the microfoope, I found them to be 

 formed in the fame manner with this in the glafs, fo that I was con- 

 vinced they had proceed from fome of the maggots which had efcaped
