Calliopsis andreniformis is a panurgine bee that inhabits much, if not all, of the eastern area of the United States. It is a small inconspicuous species. The females are about 8 mm. in length, exclusive of antennae, quite robust, general color gray, abdomen fasciate, maculation luteous. The males are more slender, smaller, maculation yellow, face and legs entirely yellow.

Since 1930 a study has been made of the lepidopterous stem borers and leaf rollers breeding on deciduous fruit trees as well as on uncultivated plants in or near orchards which have served as sites for Oriental fruit worm parasite liberations. Parasites of these lepidopterous larvae have been reared as an important phase of the study. The objects of these studies include a record of the Microlepidoptera and their hosts and parasites, and possible alternate hosts of introduced parasites of the Oriental fruit worm.

The present paper is an outgrowth of a collecting trip made by myself to the eastern arctic during the summer of 1935. The month of August was spent in the vicinity of Lake Harbour, Baffin Island, and brief stops were made at Port Burwell, Que., at Craig Harbour, Ellesmere Island, and at Pangnirtung and Clyde, Baffin Island. Results were satisfactory, considering the difficulties which the collector must experience in the region, and this success was due largely to indispensable aid received from Major D. L. McKeand of the Lands, Northwest Territories and Yukon Branch, Department of the Interior, and from Mr. James Bell and Mr. Nelson Adams of the Hudson's Bay Company, Lake Harbour.

Alate vivipara.—Color of head and thorax yellow to very light brown; abdomen pale yellow; cornicles, legs and the antennae concolorous with abdomen.

Meusurements: Body, 2.14-2.5 mm.; hind tibia, 1.08 mm.; antennal segments, III .80-.97 mm.; IV .51-.58 mm.; V .40-.46 mm.; VI .14 plus .84-.90 mm.; cornicles, .21 mm.

Female. Length about 7 mm., anterior wing 6.5 ; robust, without much hair, the abdomen bare and shining, without hair bands, but the mesopleura with rather abundant greyish-white hair; head and thorax dark green, the thorax posteriorly and at its sides almost black; mandibles black, faintly reddish apically; margin of clypeus black; face shining green; mesothorax dark, more bluish green, dull in front, shining posteriorly; scutellum steel-blue, postscutellum black, but metathorax, seen from above, olive green; legs and abdomen black; antennae black; tegulae dark brown, with minute punctures, only seen under microscope; clypeus flattened in middle, with several longitudinal grooves; front dull; vertex shining blue; mesothorax without distinct sculpture as seen under a lens, but with minute rather sparse punctures on a minutely lineolate surface; scutellum strongly bigibbous, the elevations shining; area of metathorax large, dull, with a shining margin, plications strong on basal half; posterior truncation sharply bounded; wings conspicuously reddish, stigma and nervures dull red ; second cubital cell large, receiving recurrent nervure near end; hair on inner side of hind tarsi pale reddish; hind spur with four very long oblique spines, and a fifth rudimentary one; abdomen without evident punctures, as seen under lens, the microscope shows excessively minute scattered ones.

The following is a report on certain specimens of Ichneumonidae found in a small collection of Hymenoptera made by Mr. J. A. Guignard of Ottawa, Ontario, and recently acquired by the writer, for the Canadian National Collection, through the kindness of a relative of the late Mr. Guignard.

In the last few years, Lepidopterists have devoted a great deal of interest to the genus Euphydryas. This interest, however, has resulted in a great many valid and invalid names, but in little organization or understanding of specific variation and interrelation. Gunder (Pan Pacific Entomologist, VI, 1-8. 1929), in a carefully prepared and well illustrated paper, made the mistake of lumping all American species under five specific names, which is taxonomically incorrect, regardless of genitalic similarities (Pan-Pacific Entomologist, XI, 144, 1935).
