Notes on Oregon Orthoptera with Descriptions of New Species and Races

While associated with the Oregon Agricultural Experiment Station, from 1919 to 1924, the writer collected and studied the Orthoptera of the state as opportunity permitted while carrying on the regular economic work. The more important results of these studies are brought together in this paper, which is not intended as a complete list of the Orthoptera of Oregon. The part on distribution and ecological relations is placed last so that reference to new species and races will not precede their description.
