The recent, acquisition of material in the present subfamily Malachiinae has brought to light several new species, as well as afforded an opportunity for observations on other species in the group that are believed to be worthy of recording.

The following reports the activities of the Montreal Branch of the Entomological Society of Ontario for the 73rd year.

Eight meetings were held during the 1945-46 season, six in the Lyman Room, Redpath Museum, McGill University and two in the Entomological Laboratory, University of Montreal. The average number present at the meetings was eleven, a reduction of four when compared with the figure for last year. This falling off in attendance can be accounted for in part, we believe, by the very severe weather experienced on the occasion of three of our meetings.

In his treatment of the Scoliidae in Fedtschenko's Reise in Turkestan, De Saussure divided the genus Myrmosa into two subgenera: Myrmosa sensu stricto, and Paramyrmosa, which he defined as having “the second cubital cell [of the fore wing] trapeziform; one of its sides common with [i. e. broadly sessile on] the radial cell” and by the first abdominal segment being depressed, triangular, funnel-shaped, and not as strongly nodiform as in typical Myrmosu. In this new Paramyrmosa, Saussure includes only his new Transcaspian species, Myrmosa Radoszkowskyi, which thus becomes the genotype by monotypy.

In late June, 1943, Professor G. J. Spencer and Dr. R. H. Hanford accompanied Mr. Ronald Buckell on an entomological trip into the Cariboo district of central-southern British Columbia. They planned to visit the grasshopper outbreak areas beyond the Gang Ranch, and so after driving through Clinton and up onto the Green Timber Plateau they turned west. Taking the Gang Ranch road and then the Dog Creek cut-off, they soon discovered that the preceding rainy weather and Chinook winds had made the road a quagmire. For several hours they bounced and slid from one mud-hole to the next, wading out to shove and swear when the car gave up; and upon occasion it was bogged to the running boards.

Ixodes soricis Gregson is known from the type series of adult females, nymphs, and larvae collected by Gregson from long-tailed shrews (Sorex vagrans and S. setosus) in southwestern British Columbia, and from one female collected by Robert Holdenried from Sorex trowbridgii in Marin County, California (Cooley and Kohls, Nat. Inst. Health Bull. No. 184, 1945).

Preliminary studies of the effectiveness of benzene hexachloride, or more exactly 1, 2, 3, 4, 5, 6–hexachlorocyclohexane, against the paralysis tick, Dermacentor andersononi Stiles, have revealed an acaricide more promising than any hitherto tested by this laboratory.
