steps by which that despised and almost unnoticed larva, that but a 

 few days befoi'e was grovelling in the earth, with its internal organisa-' 

 tion fitted only for the reception of, and assiniilation of, the grossest- 

 vegetable matter, has had the whole of its internal forni so completely

 air. The number of segments of which the body is normally composedi 

 is thirteen ; but some of them are so joined together, or concealedi, aS 

 to make it appear that fewer segments- are present.
