•clren, at the proper feafon, to collecl Ibnie of tliem for nie ; judging 

 tlr.it, when ilripped of tlicir wings with the cafes, and their heads and 

 ieet, the remainder would be found to reiemble Cochineah 



Thefe lady-birds, as they are called, I killed with the fmoke of 

 liilpluir, and afterwards dried them ; and when I had taken oft' the 

 red Ih.'lls or cafes which cover the hind parts of their bodies, I found 

 under them two red wings, the extremities of which were folded to- 

 gether, becaufe, being longer than the cafes, they cannot otherwife 

 be covered by them. I alfo took off their wings, feet, and heads, 

 and then I found, that the cavity which is feen on every grain of 

 Cocliineiil, is on the back or upper fide of the animalcule, and is 

 caufed by the drying ; that part of the grain which appears with a 

 kind of rifing, is the lov/er part or belly. As to thofe grains in Co- 

 chineal, wiiich have fmaller cavities than others, I conclude, that they 

 mull iiave been the female inl'edls, whole bodies, being filled with 

 eggs, do not admit of their contra61:ing in fo great a degree ; and 

 though the hind parts of the bodies of thofe infc6ls which compofe 

 Cochineal, do fomewhat difter from thofe of the lady-birds, yet, I 

 was now, more than ever, aflured, that, not only the inie^l which 

 produces the Cochineal, but alfo thofe others I have ju ft mentioned, 

 are formed from maggots or caterpillars. For, if we confider the 

 nature of all thole flying animals which are bred from caterpillars, 

 maggots, or, what are called gentles, we fhall find, that all thofe 

 annular i)arts, articulations, or circular creafes, which are in the 

 caterpillars, maggots, and gentles, are alfo found in the flying in- 

 fects bred from them ; and in the fame nund^er. To inftance in the 

 gentle, froin which tiie common fly is bred; if we examine the fly, 

 and confider its head to be comiwfed of one of the annular parts, or 

 articulations in the gentle, we Ihall find that tjic breaft to which are 

 joined the fix feet, contains three diftin^l articulations, and the hind 

 part of the body five moie. In a word, the body of the fly is divided
