Heteropogon vespoides was described in 1878 by Bigot from a single male specimen. The rather indefinite type-locality was given merely as California, as was often the practice in those days. The description was written in French, Bigot's native language. However, an excellent translation was made by Back (Trans. Amer. Ent. Soc. 35:329, 1909) who appended thereto a note to the effect that he did not believe that this species was known to recent collectors.

The dominant genus of Larrine wasps in warm countries throughout the world is Motes Kohl (olim Notogonia Costa seu Notogonidea Rohwer), but it is rather poorly represented in the Nearctic fauna. Hitherto only five species have been recorded from the United States: argentatus (Palisot de Beauvois), 1811, aequalis (Fox), 1893, nigripennis (Fox), 1893, occidentalis (Viereck), 1902, and subaequalis (Rohwer) 1909. To this roster may now be added the following two very distinctive southern forms.

In the 69th Annual Report of the Entomological Society of Ontario (1938), pages 56 and 57, the writer compares the Rhagoletis reared from dogwood (Cornus Amomum Mill.) with the morphologically similar apple maggot from apple and hawthorn.

Everyone who travels the forests or roads of Ontario and the provinces east of it must be familiar with the tent caterpillars of the genus Malacosoma. The best known of these is the orchard, eastern, or American tent caterpillar, Malacosoma americana Fab., which makes its large grey “tents” on chokecherry, apple, hawthorn, wild plum and other trees and shrubs, chiefly of the family Rosacea.

Proctacanthus brevipennis Wied. [C. T. Green]. Many of these robber flies were seen at Ranken, Missouri, on September 6, 1934. Several pairs were in copulo, and one was feeding upon a grasshopper, Syrbula admirabilis Uhler [A. B. Gurney].

It is known that selenium is highly toxic to mammals (1, 3) and to some insects (6, 8). Aphids cannot tolerate any appreciable quantities of selenium in host plants (4, 5, 10). A selenium content higher than 5 p.p.m. in cotton plants was reported toxic to cotton stainers (Dysdercus howardi Ballou) and to pink bollworm (Platyedia gossypiella Saund.) (6, 8).

During the past decade a severe outbreak of budworm has been in progress on jack pine in northwestern Ontario, following similar infestations in Michigan and Minnesota. It has been observed that budworm on jack pine does not spread to adjacent stands of balsam fir and spruce, and similarly that outbreaks on fir and spruce do not spread to adjacent jack pine stands.

The name nubilata Pack. which has been generally applied to the species with black hair-pencil at base of primaries on underside and which was figured in the Barnes & McDunnough “Contributions”, will have to be dropped as a homonym. It is preoccupied by C. nubilata Pack., 1867, Proc. Bost. Soc. Nat. Hist., XI, 48, proposed for a Labrador species; this name was later sunk by Moeschler (1870, Stett. Ent. Zt., 368), as a synonym of his lugubrata, an action concurred in by Packard (Mon. Geom., 118) who, however, wrongly transferred the name to another species in a varietal sense.
