Since the discovery of the Oriental Peach Moth in Ontario in 1925, yearly studies have been conducted to determine the extent to which our native parasitic hymenoptera have transferred their attention to this new source of host material. These studies have disclosed 15 of our native species attacking the Oriental Peach Moth, but as yet, little assistance in the form of actual control has developed from their efforts. During 1929 only 2.2 per cent. of 3298 larvae reared were parasitized by them; thus it seemed advisable to attempt the introduction of species which have proven of major importance in controlling the pest in areas of older infestation.

During the summer of 1929, Mr. W. J. Brown collected numerous specimens of Hemiptera at various stations on the north shore of the Gulf of St. Lawrence from Trinity Bay, Que. eastward to the Labrador boundary. Though the number of species obtained is not large, the distributional records are of considerable interest in that they extend the recorded distribution and add further data on the boreal and holarctic tendencies of certain groups.

In “Wasp Studies Afield” we recorded the enormous mortality of these hibernating queens in the crevices of rocky bluffs. Since that record was made, on half a dozen different occasions, I have found handfuls of dead wasps on the window-sills of several club-houses.

In his “Monographie des Guêpes,” published in 1904-05, R. du Buysson describes a new form under the name of Vespa rufa, var. intermedia. His description was based on material in the Paris and British Museums and the localities given are Lake Hanka in Manchuria and Hudson's Bay. I am not aware of any subsequent records in North America.

Male: Length 2.6-3 mm. Head, thorax, abdomen, legs and feet thickly white pruinose, but the ground color showing through; face moderately wide, wholly pollinose, this pollen yellow in the middle, reaching the orbits at the suture, sides of upper part narrowly, below the suture widely white pollinose, sonsetimes the yellow pollen covers most of upper part and extends onto the inner part of the palpi; palpi with snow white pollen, each nearly as large as upper part of face; antennae wholly yellow, small, arista whitish; orbital cilia white, rather long on the sides; occiput, front, thorax and abdomen reddish coppery, posterior margins of abdominal segments sometimes green ; bristles of thorax small, black; hairs of ahdomen very short, white; pleura and coxae black with ground color nearly concealed with white pollen, tips of coxae yellow; hypopygium small, with a long, straight, black appendage extending forward under the abdomen and small yellowish appendages inside of this long one; femora, tibiae and tarsi pale yellow, last two joints of all tarsi blackish; the minute hairs on all femora and tibiae white, the small bristles on tibiae black; fore tibiae with a row of long white hairs on upper surface, which are as long as diameter of tibiae and extend to fourth tarsal joint, becoming shorter towards the end; apical joint of middle tarsi very slightly widened; pulvilli not enlarged ; joints of fore tarsi as 20-8-6-5-7 ; of middle ones as 32-14-9-6-6; joints of posterior pair as 25-19-11-6-7.

Length 3.6-4 mm.; width 1.7-1.9 mm. Elongate oval, subequally narrowed in front and behind. Dorsum very dark brown, the anterior portion of the head pale brown, a median band extending across the pronotum sometimes slightly paler, elytra near basal and lateral margins sometimes very slightly paler; antennae reddish-yellow, the segments except the basal four each strongly infuscate except at base; legs and prothoracic venter reddish-yellow; remainder of venter black, shining.

Resembling fabae in size, form and appearance, but with distinct genital characters. Size 3 mm.

Vertex strongly produced about one third its length before anterior margins of eyes. One third wider between eyes than length at middle. Pronotum one-third longer than vertex.

On May 23, 1929 a species of Phenacoccus was found in ant's nests of the genus Lasius. Some of these were feeding on the roots of grass and were well guarded by the ants. Mature males were also found in the nest. After going carefully through the literature I find that it agrees well with the description of P. wilmattae Ckll. However, since a number of very obvious characters were omitted in the original description it will be profitable to mention them, and emphasize the outstanding differences between this species and P. stachyos Ehrhorn.
