LIST OF IOWA CLOVER INSECTS AND OBSERVATION ON SOME 

 OF THEM. 



The following list of Iowa clover insects comprises those species enumer- 

 ated by Profs. J. A. Lintner and C. M. Weed as clover feeders which are 

 known to occur in the State with such additions as personal observation or 

 accepted authority will permit. All insects listed occur in the collections 

 of the Iowa Agricultural College, and the notes in connection with any in- 

 dividual insect refer only to its occurrence on clover. 



A few doubtful determinations were referred to Prof. Herbert Osborn, of 

 Ames, Iowa.
