Interpretive Summary: Species of grass stem borers, such as the wheat stem sawfly in north central and western United States, cause extensive economic losses in wheat and other grain crops. A new species of grass stem borer was discovered in Oregon and California. The species is described and illustrated, and an identification key is given. The results will be of use to federal, state, and local agricultural agents by aiding in the identification of causes of damage to agricultural grain crops in western United States.

Technical Abstract: Calameuta middlekauffi, n. sp., is described from southern Oregon and California. It is the second species of Calameuta in North America and is differentiated from C. clavata (Norton) by the head shape and coloration. Illustrations, descriptions, and a key are given to separate the two species. The food plant is unknown, but Palearctic species of Calameuta are known to feed in grass stems.
