The following descriptions of five new genera and species of Tachinidae are based upon material received from several sources as indicated below. Most of the species have been standing in my collection for a number of years pending the accumulation of longer series. My thanks are due A. R. Brooks for the loan of some additional material recently discovered in the extensive tachinid collections in the Canadian Department of Agriculture. The type or paratype specimens, of the two species represented by this material, are returned for deposit in the Canadian Collection, as detailed under the descriptions.
