fome of thcfe W cavils coupled tcge'iher, and from this time I fre- 

 quently ini"(ie6lcd ihem, but fuw no appearance of any living creature 

 hens; produced from them until the loth of June, wlien I obferved 

 lying- among the Weevils and the wheat, two fliort and thick little 

 maggots, cne of them about the fize of a large grain of fand, and 

 the other itbout t-^e fo.irth part larger : feeing this, I opened one of 

 the q-IafTeii in whirJi I had enclofed fix Weevils, and examined the 

 ditreierjt grains of wheat that liad been put in with them, and found 

 two of them to be entirely hollow and eraptv ; from another of the 

 grains, which by the external appearance was the leaft eaten or con- 

 fumed, but had many fmail perforations or little holes not difcerni-

In other grains of the wheat I found maggots of different fizes, and 

 from one grain I took out a perfedlly formed Weevil, whofe white 

 colour ^^^s changing to a red, and \\hich was continually in mo- 

 tion. 



KKamining the other glafles, I found fome of the grains of wheat 

 iiertorated with little holes, and others half eaten. Some of the 

 Weevils which had been Unit uj) in thefe glalles I opened, and in one 

 of the females, I found five white eggs, which I conceived to be of 

 their full fize: in others I obferved eggs, fome of which were ar-

Hence I concluded, that whereas the Silk-worm's moth, living
