In the ‘Contributions’ Vol. V (2) 80/1, Benjamin has attempted to straighten out the synonymy of this species and the allied praefica Grt. Unfortunately, after carefully checking over the material in our Collection, I find that he has only added to the nomenclatorial confusion.

Two hitherto unnoticed generic names in the sphecoid wasps have recently come to my attention. Although the first, Dryphus, is clearly a synonym, as may also the second, Stercobata, be, nevertheless, since both will preoccupy any future usage of these names far valid generic entities, they are noted here in order that they may eventually find their way into the proper universal lists of generic names of animals.

Notes on several previously known generic or subgeneric names are appended at the end.

Male. Body almost entirely brown with the meso- and metathoracic tergites deep pitch-black. The three posterior abdominal segments are more opaque, somewhat deeper brown and show traces of geminate dorsal lines; ventrally these segments are paler.

The problem of controlling human lice and scabies is a serious one, especially under war conditions. During the World War or 1914-1918, lice and louse-borne diseases and the skin infection caused by sarcoptic mites were the source of large numbers of casualties arnnng the belligerents. Since that time several insecticides have been developed which show promise of being valuable pediculicides and acaricides.

In the present article I am describing a few unusually interesting species of Tipulidae from Washington, Oregon and northern California. The Oregon material was included in extensive series sent to me by Professor Herman A. Scullen, contained in the Oregon Agrircultural Experiment Station Collection, Corvallis. The Washington and California specimens, together with one species from extreme northwestern Oregon, were included in a small but very interesting series of specimens taken by Dr. and Mrs. Henry K. Townes and kindly presented to me by the collectors. I express my indebtedness to these entomologists for this continued interest in making known the crane-fly fauna of the Vancouveran faunal area.
