It has commonly been observed that grasshoppers readily feed upon dry bran that has never been wetted. From this it was thought that an efficient dry bait might be prepared by spraying concentrated poison solution directly on to an attractive carrier.

There is apparently no mention in Canadian literature of the genus Sandalus. No Canadian specimens are present in the collections of the Royal Ontario Museum, Toronto, and there are only two specimens of Sandalus niger Knoch, from London, Ontario, at the Ontario Agricultural College, Guelph. Previous to the writer's donation, there were none in the Canadian National Collection at Ottawa.

This report includes descriptions of five apparently new Diptera of the family Dolichopodidae. The Colorado specimens were studied through the cooperation of Doctors M. T. James and R. H. Painter. Doctor James is codescriber of Scellus coloradensis and Rhaphium colutis, which are here described as new.

There commonly occur in the bark of decadent elms certain species of coleopterous larvae which are often difficult to distinguish unless they can be positively associated with their maternal egg gallery. In handling large numbers of these larvae for precise experimental purposes and in field work, satisfactory criteria for exact identification consisting of definite external morphological characters, capable of rapid use, are necessary.

The genera here under consideration are largely western and southwestern in distribution. Little or nothing is known concerning their biology or host relationships. Characters common to both genera include the following among others: eyes bare; parafacials setose to bristled; facial ridges practically bare; epistoma narrow and somewhat elongated; arista short plumose; propleura bare; prosternum setose; apical cell closed with long petiole reaching costa far before wing tip; costal spine large; sides of postnotum beneath calypters haired.

The type specimens of the two species of Rhysodesmus described below were collected by Mr. Phil Rau, through whose courtesy the author received them for study. The specimens are at present in the author's collection.

I am by no means certain that flavicornis Sm. can be considered distinct specifically from propinquilinea Grt. Originally described as Demas flavicornis from a New Jersey specimen in the Graef Collection (which should now be in the United States National Museum) it was probably considered distinct from Grote's species, described under Charadra, on generic characters.
