The following record of species represents the collections of Hemiptera made during four days (Aug. 28, Sept. 1, 1900) at points within five miles of Bellaire, all on the Ohio side of the river. Wooded hillsides, valleys, creek bottoms and shore and island of the river were worked during a part of each day and as the list includes one hundred and forty-nine species, it is probably fairly representative for the common species of the season.
