Professor Morse's well-known “Manual” treats of the orthopterous fauna of Massachusetts in general, but of the eastern maritime area in particular. The region extending from the Worcester Plateau to the New York State Line includes a variety of environment which apparently have not been examined from the standpoint of Orthoptera nearly as thoroughly as the eastern half of the state. The present list of Acrididae is the result of collections made by the writer chiefly at Cummington and about Amherst, during the past three years. Like our native ferns,grasshoppers arc usual1y found amid surroundings suited to the ecological complex of the particular species concerned. Mention of some differences shown by the Life Zones of western Massachusetts may be helpful in understanding the distributional factors of local Acrididae.

In the course of an investigation of the secondary sexual characters of Saprinus assimilis Payk, the writer found five specimens of an hitherto undescribed species of Saprinus. At the request of Mr. Henry Dybas, who submitted the material for determination and study, the description of the species is included with the following notes.

Aphids of many kinds persist in causing injury to range plants as well as to shade, forest, ornamental and crop plants. The following report deals largely with aphids taken in Utah and nearby states. The writer is indebted to Dr. A.A. Granovsky of the University of Minnesota for identifying a number of the species belonging to the tribe Callipterini.

In handling some miscellaneous material belonging to the U. S. National Museum the writer noticed a unique specimen of a new genus and species of much interest as presenting additioiial evidence of the close relationship of those two large and important families, the Arctiidae and the Lymantriidae. A similar specimen, submitted by Dr. J. McDunnough, has served to amplify the descriptions.

While at the University of Toronto in the spring of 1934, the author had the privilege of examining the Plecoptera of the collection of the Royal Ontario Museum of Zoology. It soon became apparent that a number of undescribed species were represented therein, and the present paper describes three of the most interesting of them. It is the interest and assistance of Dr. E. M. Walker and Dr. F. P. Ide that has made possible the descriptions appearing in this and in subsequent papers.

The nematine genus Dineura has had assigned to it at various times several species of nearctic sawflies. A close study of these species indicates that Dineura itself is not represented in our fauna, but instead three genera which resemble it in wing venation. This complex was considered by MacGillivray as the sub-family Dineurinae, but as pointed out by Rohwer it is in reality part of the Nematinae. The three genera involved may be separated from the other Nematinae by having the front wings with the base of vein 2A and 3A absent and the second radial cross-vein (2r) present. The extreme differences between the genera suggest strongly that the segregate is purely an artificial one based only on accidental similarity in venation.
