 kind. Thirty species. 



Case R. Objects of insect architecture, with the species employed 

 in producing them. Forty-eight specimens. 



Cases S and T. In these two cases are shown seventy species of 

 the most common forms of our beneficial insects. [These should have 

 been placed after the insects they destroy, in the general collection, 

 but it was decided to group them together for the present.] 



Case U. Thirty-one species of insects beneficial as scavengers, by 

 removing filth and carrion. 



Case V and IV. These two cases are devoted to silk-producing 

 insects, and contain about thirty specimens illustrating this industry. 



Case X. In this case are gathered together a few " insecticides," 

 so-called, and traps or devices for destroying insects. 



I have thus endeavored, briefly, to give an outline of the plan of ar- 

 rangement of this collection, mentioning merely the groups illustrated 

 as a catalogue of the insects themselves would take more space than 

 could be spared for the purpose.
