North- American Insects. 19 



HYMENOPTERA, RHYNCHOTA, NEUROPTERA, 

 AND ORTHOPTERA. By W. F. KIRBY. 



Only a few species of these orders were obtained, and in 

 most cases only single specimens. Some of these belong to 

 well-known and widely distributed North-American species ; 

 but several of the remainder belong to imperfectly studied 

 groups, in which the genera only can be determined with 

 certainty from the materials before us. Most of the specimens 

 were taken at Carberry, Western Manitoba, on August 4, 

 1892.
