ENTOMOLOGICAL EXHIBITS AT THE NEW ORLEANS 

 . EXPOSITION. 



BY THE EDITOR. 



The United States Government exhibit, and those of several of the 

 States, at the New Orleans Exposition, included many features of interest 

 to the Entomologist. The Entomological Bureau of the Department of 

 Agriculture had a very fine display illustrating Economic Entomology, 

 which was brought together and arranged under the direction of Prof. 

 Riley, and was not only interesting, but very instructive. 



The first thing that caught the eye of the visitor on entering this 

 section was a series of large diagrams on cotton, illustrating the hfe history 

 of a number of injurious insects, such as the Plum Curculio, Cono-

 strawberry, raspberry, currant, gooseberry, melon, cranberry, persimmon, 

 grape, su^ar cane, hop, rice, Indian corn, small grains, cotton, grass, 

 clover, pea, bean, cabbage, potato, tomato, tobacco, asparagus and onion.

 insects the pupte and blown larvae, with specimens of the articles injured, 

 also the friendly insects which aid in subduing those which are injurious. 



There was a very interesting section relating to bees and bee-culture, 

 including all sorts of hives and apparatus, specimens of the different races 

 of bees, with dried specimens of the plants and flowers from which honey 

 is chiefly extracted. 



A large department was filled with every kind of spray apparatus for
