The new speciesdescribed in this paper were incruded in very
extensiye collections made in Alaska by Dr. J. M. Aldrich, and in
IVestern LTnitedstates, British c.lumbia and Araska, by Dr. [ra""i"on
G. Dyar. The two collections taken together, rvhich belong to theunited states National Museum, constitute one of the mosi important seriesof thesoflies that has yet beeubrought togetherfrom thisregion. rn the present psper a part of the undescribetl forurs areincluded. rt is hoped that detailed recordsof all the included species can be brought together and published in a second report onthese flies. All types have been deposited in the collection of theUnited States l{ational Museum.

Very similar to P. tenu,ipes(Say), with the following exceptions:
Antennae of the male short, if bent backward barely reuching thewing-root. 'Ihoracic stripes very distinct, dark brown, confluent.
