 we have seen the first three pairs are articulated, the re- 

 mainder are membranous; the three first, a rude type of what 

 the perfect insect will ultimately possess, the five others will 

 entirely disappear in the first great change to pupa life. 



OaOANS OP VISION. 



The organs of vision in larvae are very different to what 

 we shall find them in the perfect insect ; they now are only 

 simple in their construction, consisting only of a single 

 lens, and are placed on the side of the head near the 

 mandibles, and vary in number, scarcely ever exceeding 

 sis, but amounting to thousands when the insect has 

 perfected its final condition. 



0EGA.N8 OF MASTICATION. 



Whilst in the larvae state the insect has a very different 

 mouth-piece to what it will ultimately possess : it has now 

 one adapted to the condition it which it has to exist. It 

 must feed from vegetable or animal substances. By the 

 laws of its economy it must attack our vegetable world out 

 of doors, and our animal products within. lu the larval 

 condition I believe there is no tree, flower, or shrub that 

 has not its parasite in the shape of some devouring cater- 

 pillar; and our woollen stuffs, our clothes, and our blankets 

 our museums of animals, our collections of birds, our 

 cabinets of insects, all are fit and proper food for larval life, 

 and all are preyed upon : indeed, it is but pollowinq
