y-s HISTORY OF 



given the history of grubs changing into their 

 corresponding winged animals. These, like the 

 former, undergo their transformation, and appear 

 as grubs or maggots, as aurelias, and at last as 

 winged insects. Like the former, they are bred 

 from eggs ; they feed in their reptile state ; they 

 continue motionless and lifeless as aurelias, and 

 fly and propagate, when furnished with wings. 

 But they differ in many respects : the grub or 

 maggot wants the number of feet which the ca- 

 terpillar is seen to have; the aurelia is not so 

 totally wrapped up but that its feet and its wings 

 appear. The perfect animal, when emancipated, 

 also has its wings either cased, or transparent like 

 gauze ; not coloured with that beautifully painted 

 dust which adorns the wings of the butterfly. 



In this class of insects, therefore, we may place 

 a various tribe, that are first laid as eggs, then are 

 excluded as maggots or grubs, then change into 

 aurelias, with their legs and wings not wrapped 

 up, but appearing; and lastly, assuming wings, 

 in which state they propagate their kind. Some 

 of these have four transparent wings, as bees ; 

 some have two membranous cases to their wings, 

 as beetles ; and some have but two wings, which 

 are transparent, as ants. Here, therefore, we 

 will place the Bee, the Wasp, the Humble Bee, 

 the Ichneumon Fly, the Gnat, the Tipula or 

 Longlegs, the Beetle, the May Bug, the Glow- 

 worm, and the Ant. The transformations which 

 all these undergo are pretty nearly similar ; and 

 though very different animals in form, are yet 

 produced nearly in the same manner.
