A list of the Orthoptera at the summer biological station of the University of Michigan has been published, but no records of dates or habitats has been included. During the summer of 1912 the writer collected Acridiidae at Douglas Lake, in Cheboygan County, seventeen miles south of the tip of the southern peninsula. In addtion to records and habitat notes obtained, six species were taken which had not been listed from the region. The Tettiginae collected were few, and the notes below refer only to members of our other three sufamilies.
