Abstract
Four impressions of grasshoppers were discovered during investigations of fossil insects from the Ruby River Basin of Montana. The 4 specimens represent the first to be recorded from this locality. The fossils were found in paper shales of Oligocene age between Peterson and Morman Creeks, sec. 23, T. 7S; R.5 W., Madison County, Mont. The digging sites are located ca. 13 miles from the town of Alder, Mont. A brief description of the geologic history of this region can be found in a previous paper (Lewis 1971).
