ADDITIONS TO THE LIST OF HEMIPTERA OF IOWA, 

 WITH DESCRIPTIONS OP NEW SPECIES. 



BY HERBERT OSBORN. 



A number of additions to the Hemipterous fauna of the state 

 have been made during the last year, either by collection or by 

 the determination or description of specimens previously in 

 hand, and although there are certainly many others to add it 

 seems desirable to record such as have come to notice. In many 

 cases the record greatly extends the range of the species as 

 heretofore known.
