The list of species determined or confirmed follows, with comments.

The collection from which this study was made was obtained through the courtesy of the Entomological Branch, Canadian Department of Agriculture, and was of particular interest in that it not only contiained excellent series of many of the described forms but also several undescribed species. Descriptions of the latter are submitted in the present paper together with notes on some of the others.

The following descriptions of five new genera and species of Tachinidae are based upon material received from several sources as indicated below. Most of the species have been standing in my collection for a number of years pending the accumulation of longer series. My thanks are due A. R. Brooks for the loan of some additional material recently discovered in the extensive tachinid collections in the Canadian Department of Agriculture. The type or paratype specimens, of the two species represented by this material, are returned for deposit in the Canadian Collection, as detailed under the descriptions.

In 1957, a program of introducing insect predators for control of the balsam woolly aphid, Chermes (= Adelges) piceae Ratz., was begun in Oregon and Washington. This program was made possible through the generous cooperation of the Canadian Department of Agriculture, which provided many of the predators. Eighteen predator species from Europe, Asia, and Australia were liberated from 1957 through 1960. Four of the species are known to have survived one or more winters and show promise of becoming permanently established.

During 1954, I had the opportunity of examining a large collection, circa 3,500 of unidentified Corixidae which had been accumulated in the Canadian Department of Agriculture over a period of years. These notes consist of a list of species identified, with observations where pertinent when these records are new state or country records compared with the full lists of localities given in H. B. Hungerford's ‘The Corixidae of the Western Hemisphere’ 1948, Univ. Kansas Sci. Bull. Vol. XXXII, pp. 1-827.

In 1937-38 the Argentine Department of Agriculture initiated an exchange of grasshopper parasite material with the Canadian Department of Agriculture which was engaged in a study of the natural control of grasshoppers in various provinces of Canada. By 1942 it was considered desirable to introduce exotic species of parasites into Canada on as wide a scale as possible, and the temperate regions of South America were selected as being the most promising for a survey. The parts of the temperate zone of South America to which preferential attention was to be given included the countries of Uruguay, Argentina, and Chile. The well known grasslands of the Rio de la Plata area have been partially transformed into one of the world centres for cereal production and as in other parts of the world increased grasshopper populations constitute a major problem in the agriculture of the region. Here species of the genus Dichroplus are frequently pests in the way in which members of the closely related Melanoplus are in North America.

The first reindeer were introduced into Canada for humanitarian rather than commercial reasons. Encouraged by the success achieved in Alaska, where 1280 reindeer imported by Dr Sheldon Jackson from Siberia between 1892 and 1902 had increased in a few years to several times that number, the missionary physician of Labrador, Wilfred Grenfell, hoped to develop a reindeer meat-and-dairy industry in his region, where tuberculosis was common and infant mortality high. In 1908, with financial support from the Boston Transcript and the Canadian Department of Agriculture, he bought 300 reindeer in Norway and brought them to St Anthony, Newfoundland. Under the supervision of four Lapp herders, the animals quickly adjusted to their new environment

The name Pseudolitomastix was applied (Eady, 1960) to a genus erected for the new species P. nacoleiae, bred from Nacoleia octasema (Meyr.). This unfortunately overlooked the valid and prior use of the name Pseudolitomastix, by Risbec (1954). The two species for which Pseudolitomastix Risbec was erected are generically quite distinct from P. nacoleiae, so that a new generic name is required for this latter species. The name Pentalitomastix, indicative of the five-segmented funicle of the female antenna, is hereby proposed. I am grateful to Dr. O. Peck, of the Entomology Research Institute of the Canadian Department of Agriculture, for drawing my attention to the homonymy, and to my colleague Mr. G. J. Kerrich for suggesting the new name.

Since the publication of my revision of the genus Exenterus (U. S. Dept. Agr. Misc. Pub. No. 354, 1940) several pertinent items of interest have come to my attention.From the Canadian Department of Agriculture, through G. Stuart Walley, I have received specimens of two undescribe species, one in considerable nnmbers, the other represented by only a single specimen.

Recently Dr. R. N. Sinha, of the Canadian Department of Agriculture, sent in for determination some spider mites causing serious damage to barley in Manitoba. Previously this same mite had been collected in North Dakota and Oregon. The mites proved to be an undescribed species of Tetranychus, a genus not usually associated with grasses.
