ABDOMEN. 69 



a place for the egg, but in others of a set of carpenter's 

 tools, as it were, for boring and filing, and sawing and 

 cutting; some of these boring tubes being, indeed, three 

 or four times the entire length of the body, and with 

 these they are able to drill into the most solid wood 

 often to the depth of three or four inches, and there 

 deposit the egg in the body of the larva of some other 

 insect, or even within some other egg. Some of these 

 organs are fashioned as shovels or spades for digging in 

 the earth, others as scissors for cutting filaments of 

 leaves, or as stings endowed often with a powerful, acrid 

 poison, as many of us may have experienced from the 

 bee, wasp, or hornet. 



In this connection a great deal might be said in rela- 

 tion to the architecture of the nests of insects^ as that of 

 the honey comb, paper wasps' and mud wasps' nests, 

 dwellings of the carpenter bee, ant hills that we may ex- 

 amine in almost any forest, the gigantic structures of the 

 Avhite ant or termites, and many other forms that would 

 furnish of themselves a world of wonder and interest; 

 but we will be obliged, with this bare outline, to close 

 our remarks relative to the external anatomy of the 

 Imago J and ay a few words in. relation to its internal 

 anatomy.
