Notes on Some Types of American Muscoid Diptera in the Collection of the Vienna Natural History Museum.

Abstract

The United States National Museum, through the work of Coquillett, Townsend, and others, has become the repository of a large amount of type material in the muscoid group. Except in Anthomyiidæ, always to be included under the term muscoid (which is merely an equivalent for the older “Muscidæ Calyptratæ”, the National Museum contains most of the type material in existence in America in this group.
