In 1951 to 1955 Mr. N. H. Anderson of the Belleville laboratory, and Mr. C. V. G. Morgan, Entomology Laboratory, Summerland, B.C., collected plant material in southern British Columbia to investigate the distribution there of phytoseiid mites. Many phytoseiids in this material were apparently undescribed, and in 1956 the author collected further specimens. Nine undescribed forms were found; descriptions of these are given below, with a key for identifying the adult females of all phytoseiid species known to occur in British Columbia. The new species all are of the genus Typhlodromus Scheuten, 1957, as defined by Chant (in preparation). The mites were cleared in chloral hydrate or lactic acid and mointed in Berlese's fluid; but some were mounted directly in De Faure's fluid. The measurements given are of the greatest lengths and widths of the dorsal and ventri-anal shields, and whenever possible are the means for 10 specimens. The setal terminology of Garman (1948) and Nesbitt (1951) is followed. All specimens referred to were collected in British Columbia unless otherwise stated.

The genus Hystrichopsylla is Holarctic in distribution; its species include the largest known fleas. Only a few of the species exhibit marked host preferences. H. talpae (Curtis), the type of the genus, occurs through much of Europe and Asia, where the favoured hosts are insectivores and small rodents. It differs from all other known species chiefly in the presence of true combs of long, pigmented spines on abdominal terga II to IV (Fig. 1). Because of the differences, Ioff and Scalon (1950, in Ioff and Scalon et al., p. 273) proposed the subgenus Hystroceras (type, H. satunini Wagn.) to contain a group of Palaearctic species (satunini Wagn., microti Scalon, and nicolai Scalon) that have the abdominal combs reduced to series of apical spinelets (Fig. 2); this taxon would include all the known Nearctic species of Hystrichopsylla. Ioff and Scalon considered Typhloceras Wagn., known only from the Palaearctic region, a third subgenus, but this interpretation will probably not be generally followed.

Cases of furuncular myiasis in humans have been reported in the literature from time to time, many of them having been attributed to parasitism by sarcophagid flies. O'Rourke (10) described a case of furuncular myiasis due to Wohlfahrtia vigil (Walk.) in a month-old infant at Ottawa. He reviewed the life-history and distribution of the species and previous records of myiasis cawed by it. Israels and Shuman (4) published an informative general review of myiasis dermatosa. Hunt and Edwards (3) reported a case in a three-month-old infanr at Montreal. This is a report on similar cases that occurred at Lethbridge, Alberta, in 1953 and in 1955 and a review of other records for Western Canada and the United States.

Since 1945, the European red mite, Metatetranychus ulmi (Koch) [=Paratetranychus pilosus (C. & F.)], has been one of the major pests in apple orchards in southwestern Quebec. Though it had been noted by Petch on fruit trees at Ville LaSalle, Que., in 1930 and at Lac Mégantic, Que., in 1931 it was not reported as causing serious injury to apple trees before July of 1945, when Beaulieu (1948) reported that it was responsible for the first important damage in a few orchards at Rougemont, Que. By 1946, infestations were general in the apple growing areas of southwestern Quebec and occurred as far east as the Quebec City district.
