A New Species

The following is a description of a new species of predacious mite of the subfamily Phytoseiinae. It is found in orchards in Nova Scotia on the bark of apple trees, but in no instance has it been taken from the foliage. This species is similar in structure to Typhlodromus tiliae Oudmus. (Nesbitt, 1951), but its habits differ. In this paper the differences between T. tiliae and the species herein described are noted and details of a laboratory study of the life-histories and food habits of these species are given.

Typhlodromus pyri Scheuten (= T. tiliae Oudms.) is the predominant species of predacious mite on apples in Nova Scotia. It feeds on a wide range of prey species (Herbert, 1959). Chant (1960) investigated the life-history and habits of this species in southeastern England and Herbert (1956) studied its life-history under controlled laboratory conditions. A knowledge of the life-histories of various components of the fauna is basic to an evaluation of predation; therefore, a study of the life-history and habits of T. pyri in the field was undertaken. This was supplemented by a laboratory study in which an attempt was made to duplicate field temperarures. The results of these studies are presented here.

A New Species

In the Proceedings and Transactions of the Nova Scotian Institute of Natural Science (1868-9, p. 78-87), I have given a list of some specimens of Nova Scotian Lepidoptera, sent me for determination by the esteemed President of the Institute, J. Matthew Jones, Esq., of Halifax. Among these was included a new species of Anarta, the description of which I reprint here, as many of those interested in this department of Entomology may not have access to the original publication.

AbstractThe relative densities of phytophagous and predacious mites within mature apple trees were examined. The eggs of phytophagous mites Aculus schlechtendali (Nal.) and Panonychus ulmi (Koch) were more numerous in the lower position of the tree while the reverse was true for the predacious mite Zetzellia mali (Ewing) and its eggs.

A New Species

The ‘clover’ mite, Bryobia praetiosa Koch, has long been known to be a complex of closely related species or biological races differing greatly in host range, life-history, and habits. Morgan and Anderson (1957) reviewed the problem and described the form occurring on fruit trees in British Columbia as a new species, B. arborea, to be known as the brown mite, and these authors (Anderson and Morgan, 1958) also published a detailed study of the life-histories and habits of this species and of the true clover mite, B. praetiosa. Although the presence of Bryobia mites on fruit trees in Eastern North America, including Ontario, has long been recognized, they have seldom received more than casual mention and no extensive study of their biology in this area appears to have been undertaken. The species has little economic importance in Ontario (Putman and Herne, 1959).

Specimens were collected from soil under pistachio trees at Boshroyeh vicinity, south Khorasan province, Iran. Also a known species, S. pilatus Kuznetzov, collected from soil under plum and apple trees at Maryanaj vicinity, Hamedan province, Iran, is re-described. A key to all known Iranian species of the genus is provided.

Group 1

Macrochemical reactions are reported on 15 species of Suillus, 3 of Fuscoboletinus, 2 of Gyroporus, and 1 species each of Boletellus, Boletinellus, Pulveroboletus, and Strobilomyces, together with a number of tests on species of Tylopilus and Boletus not available for an earlier paper. Three species of Suillus and three Boletus species are new records for Nova Scotia, and two of these are new for Canada. Also included are tests for a new species of Boletus to be described in another paper.Similarities in the macrochemical tests are used to divide 13 of the species of genus Suillus into two groups. Suillus luteus was selected as the type for group 1 and S. americanus for group 2. Two species did not belong to either group and were distinctly different from each other. Two species of Fuscoboletinus could be placed with group 2, but the third, F. paluster, differed widely. Boletus piperatus, which has been placed in Suillus by some authors, does not appear to be related on the strength of these tests. No attempt was made to group other species in Boletus or Tylopilus.

A New Species

Holasaphus centropyge Matthew, 1895, the type species of the genus, is redescribed using known and new material from the Middle Cambrian of Nova Scotia. A new species, Holasaphus mesopotamicus, described from the Derik–Mardin district of southeastern Turkey, marks the only other known occurrence of the genus. The presence there of Holasaphus and the agnostid Peronopsis in the middle portion of the Sosink Formation suggests that the latter may be no younger than Middle Cambrian and lends additional support to evidence for the probable regional absence of Upper Cambrian strata.
