The series of papers entitled “Observations on the Chermidae (Hemiptera: Homoptera)” is to be considered as closed. Mr. Fred Klyver, author of the accompanying paper, will continue the series under the general title of “Notes on the Chermidae (Hemiptera : Homoptera).” There is appended herewith a bibliography of the former series and other papers on the Chermidae by the present writer.

♂ ♀. Head.—The rostrum equals the fore coxa in length. The maxillary palpi are slightly more than two-thirds the length of the rostrum. The frons is broadly rounded. There is a lower general row of three stout bristles and an upper genal row of six bristles. There is no genal ctenidium. The occipital bristles are arranged in three rows. The bristles of the second antennal segment are short and fine. The club of the antenna is distinctly segmented all of the way around.

The identity of Scotogramma oregonica Grote has always been a matter of some doubt to taxonomists. Smith gave his idea of the species in a paper entitled “Notes on Mamestra trifolii Rott. and Its Allies” (1910, Ent. News, XXI, 357); Wolley-Dod (1913, Can. Ent., XLV, 31) surmises a mixture of species in Grote's type lot of material and states that the male type in the Neumoegen Collection at Brooklyn (now incorporated in the U. S. Natioonal Museum) is the same as Smith's morana (op. cit., p. 361) ; following Dod morana was made a variety of oregonica in the 1917 Barnes and McDunnough Check List.

While endeavouring to secure my supper from the North Fork of the Ghost River, in the foot-hills of Alberta last summer, it was my good fotune to land an eighteen-inch trout. I immediately set to work dissecting his stomach to determine upon what he was feeding, and the contents surprised me in no small way.

Selandria Leach and Coryna Lep. include the nearctic sawflies of the subfamily Selandriinae in which the costal vein is strongly swollen at its apex. They are of a short and robust form. Enslin (1913) considers Coryna as a subgenus of Selandria, whereas Rohwer (1928) considers the two as distinct. The characters given in the table for the separation of the two genera seem to be sufficient for considering Coryna a good genus.

In checking over the described species of Tiphia the writer found seven uncorrected homonyms in the genus. Since the activities of the U. S. Department of Agriculture in fighting the Japanese beetle (Popilla japonica) have partially taken on the aspect of biological control, and many species of Asiatic Tiphia have been imported into America, it seems advisable to the writer that the following corrections of specific and variety names be made immediately :

Tiphia intermedia var. EXITIALIS n. n.

In view of the fact that several inquiries have been made concerning the type locality of two species of Staphylinidae described by Herr Hans Wendeler of Berlin, it appears desirable to clarify the published citations.
