Corixidae of Georgia. 



By J. F. Abbott, Washington University, St. Louis, Mo. 



During the summers of 1909 to 1912 Prof. J. Chester Bradley, in 

 his capacity of Special Assistant to the State Entomologist of Geor- 

 gia made important collections of insects, including many aquatic 

 Hemiptera. This group he turned over to Prof. J. F. Abbott, of 

 Washington University, who has worked up the Corixidae. The 

 editors trust that this is the beginning of a series of definitive 

 papers on the neglected families of this order. A practical key 

 for the determination of the species has not hitherto been ac- 

 complished. — Editors.
