Predators are the most important natural enemies of the European red mite. Notes are given on the life history and habits of the following predaceous enemies of this mite, Seiulus pomi Parrott; Diaphnidia pellucida Uhl.; Diaphnidia capitata Van D.; Hyaliodes vitripennis Say; Stethorus punctum Leconte; Plagiognathus obscurus Uhl.; Camptobrochis nebulosus Uhl.; Anystis agilis Banks; Campylomma verbasci Mey., and an unidentified species of Syrphidae.

The life history of Phaeosaccion collinsii Farlow, a species which is known from a single locality in Nova Scotia, has been completed in culture. There was no indication of a sexual phase and zoospores gave rise directly to the tubular thallus. Completion of the life history occurred at 5 °C only. At higher temperatures spores failed to germinate, or growth and differentiation were suppressed. Light intensities exceeding 100 ft-c inhibited spore germination, although growth and differentiation were not similarly affected. In nature mature plants occur sublittorally, and are present only in spring when the water temperature is around 5 °C. Zoospore flagellation is of the typical heterokont type with the flimmer bearing bilateral hairs. On this basis P. collinsii can be placed either in the Chrysophyceae or Phaeophyceae.

New Pest

Stibaropus tabulatus, Schiödte, a Pentatomid bug of the subfamily Cydninae, is remarkable in having the unusual habit of living underground and attacking the roots of tobacco, and to the best of the writer's knowledge this is the first record of this species as an insect of economic importance; though Lefroy has mentioned the allied S. molginus, Schiödte, in his “Indian Insect Life” (p. 674) as having been observed at the roots of a palm in South India at a considerable depth below the surface. As the insect under report was something of a novelty and was a pest of such a valuable crop like tobacco, the writer made special efforts to study its life-history and habits, and it is the aim of this paper to place on record the results of his observations and studies, though he regrets that they are somewhat fragmentary in character.

A comparative study of Dibotryon morbosum (Sch.) Th. & Syd. on peach and plum showed the life cycle to be the same on both hosts. Peach knots were less prominent and produced very few mature perithecia. Plum inoculum was considered to be largely responsible for infections on the peach. The morphology and cultural characteristics of the isolates from the two hosts were similar. Ascospores from plum knots readily infected peach seedlings but those from peach knots did not infect peach or plum seedlings. The colonization of knots by extraneous organisms affected the maturation of perithecia. Of the fungicides used thiram was the most satisfactory for the control of black knot on plum. These investigations indicate that black knot is not of serious economic importance on peach.
