The Fire Brat, Thermobia domestica Packard, seems to have been in Eastern Canada for some time. Since, as its nick-name indicates, it is a heat-loving species, favouring steam-heated buildings, it has probably been established in the country for a long time although the records of its distribution in Canada are few and are all fairly recent.

Length 6-6.3 mm. ; width 2.6-2.7 mm. Oblong, moderately convex and elongate, parallel. Black; the legs and elytra very dark reddish brown, almost black; shining.

Mr. C. A. Frost, the coleopterist, to whom of recent years I have been indebted for many interesting and, indeed, rare Heteroptera, has again favored me with some unusual species taken by him this summer (1929), in Nova Scotia. Portaupique, so I learn from Mr. Frost, is on the North shore of Minas Basin, 30 miles west of Truro; Westchester is up in the hills at a lake in the spruce woods.

In working over nzaterial received for identification from S. C. Bruner and G. N. Wolcott, the following new species were found.

Studies by Eaton (1884), Dodds (1923) and Needham (1905, 1927) have contributed much to our knowledge of the nymphal forms of Ephemerella occurring in Western North America. Needham's recent paper on “The Rocky Mountain species of the Mayfly genus Ephemerella” contains a valuable discussion of the nymphs of that region and is the first attempt to treat of the species in a comparative manner.

In 1909 I was interested to hear from a farmer in Ontario, that barn swallows are undesirable because they harbour bedbugs which spread from their nests to human habitations. Several times since I have heard the same complaint from various sources. In 1926 an instance cropped up in Vancouver where cliff swallows nests were systematically knocked down from some public buildings, for the same alleged reason.

On August 8th, 1926, I captured a sawfly of the genus Croesus at the flowers of the common parsnip (Pastinaca sativa) at the foot of Mount Royal.
