Abstract
This insect was first known in 1876, near Fremont, Nebraska, where it was taken and named. It then disappeared from that vicinity, its disappearance caused, it has been surmised, by the severe grasshopper invasions of 1875 and 1876, and was unknown until 1911 when it was reported as doing much injury to small grains in Alberta, Canada. During the succeeding years it appears to have moved south, or, possibly, to have multiplied locally, and in 1919 it was doing noticeable damage to crops in eastern Montana and western North Dakota. Its chief injury was to wheat and corn but it also attacked rye, barley, oats and, to a limited extent, flax and millet, also potatoes.
