232 IOWA ACADEMY OF SCIENCES. 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.
