Abstract
A new species of fossil syrphid has been discovered in the paper shale deposits of the Ruby River Basin of Montana. It belongs to the genus Tropidia Meigen, and represents the 1st species of this genus to be described from this locality. The fossil was found in layered shale of Oligocene age between Peterson and Morman Creeks, Sec. 23, T. 7 S, R. 5 W, Madison County, Mont. The diggings are located ca. 13 miles from the town of Alder, Mont. A brief description of the geological history of this region can be found in a previous paper (Lewis 1971).
