THE INSECT GALLS OF CEDAR POINT AND VICINITY. 
Paul B. Sears. 
(Department of Botany, University of Nebraska.) 
The following list is based on rather careful collections made 
during the summer of 1914. Since the list contains many forms 
common throughout Ohio, I have aimed to make the synonymy 
fairly complete to date, as an aid to students, while the biblio¬ 
graphy has been limited to original description (where possible) 
and some more recent notice which should be helpful. 
In the course of this work I have become deeply indebted to 
Mr. W. J. Kostir, of Ohio State University, while Prof. Herbert 
Osborn, Prof. B. W. Wells, Prof. Myron Swenk, Miss Edith 
Patch, Mr. Nathan Banks and others have shown me various 
kindnesses.
