Dr. H. T. Fernald (4) gives as synonyms of Sphex aberti (Hald) the names Ammophila yarrowi Cress. and A. moontezuma Cam. This species was one of the first of our wasps to which has been ascribed the rernarkable habit of using a pebble or other suitable object as a tool. The observation was made by Dr. S. W. Williston (9) in 1892 on specimens determined as A. yarrowi. He considered the habit so unusual that he refrained publication for a time thinking the act might be doubted. It is now an accepted fact, though somewhat variously interpreted, and has been witnessed by a number of careful and accurate observers in this and other species.

In a recent number of the “Canadian Entomologist” (LXII, 75, 1930) the writer reported on a collection of Heteroptera made on the north shore of the Gulf of St. Lawrence during the summer of 1929, by Mr. W. J. Brown. From collections made in the same region during 1930, fifteen additional species were obtained. These additions are given below following which is a complete list of Homoptera obtained during the two summers, 1929 and 1930. All localities cited are within the Province of Quebec.

The Canadian bees now described were received from Mr. Albert F. Winn; the types are in my possession.

Andrena lucifera n. sp.

♀. Length about 9 mm., expanse 18; black, including mandibles and legs, the antennae black with the flagellum thickened and faintly brownish beneath beyond the base; pubescence of head and thorai very scanty, dull white, the thorax almost nude above, the sparse hair easily deciduous; head broad, facial quadrangle conspicuously broader than long; mandibles ordinary, malar space linear; process of labrum very large, obtusely triangular, shining; clypeus wholly dull, with a minutely granular surface, and sparse punctures; no smooth line, though the middle is slightly elevated: on each side above the clypeus, from the antennae to the orbits, is a broad highly polished area, but the supraclypeal area and middle of front are dull; facial foveae moderately broad, with shining white tomentum; distance from upper end of fovea to lateral ocellus about or nearly as great as width of fovea; below the foveae extend (with approximately even width) below level of antennae, and are separated from orbits by a shining line; cheeks shining, convex, very broad, the upper part strongly keeled behind; third antennal joint fully as long as 4+5; meso-thorax dullish, more shining posteriorly, without evident punctures under a lens, but the microscope shows a minutely tessellated surface and scattered small punctures; scutellum polished, with a median impressed line; mesopleura glistening, rugulose, the lower part produced into a sort of tubercle, and the shining anterior face of lower part having a triangular outline; metathorax dull and granular, but the large basal area triangular, with numerous conspicuous plicae, radiating at sides and a few stronger ones in middle; tegulae reddish brown, anteriorly blackened; wings conspicuously reddish, stigma dark reddish brown, the middle darker than the margins, veins brown; basal nervure falling well short of nervulus; second cubital cell narrow, much higher than broad, receiving recurrent nervure not far from end; legs with pale brown hair, the hind tibial scopa wholly pale, faintly reddish, the hairs on outer side simple; spurs normal, pale reddish; abdomen broad, highly polished, nude above, without bands, the hind margins of the tergites obscurely brownish; under a lens no distinct punctures are visible, but the microscope shows sparse minute punctures; apical depression of first tergite short, of second less than half distance from base to apex, but rather more than two-fifths; apical fimbria pale brown; venter with dull whitish hair.

This rather small species was named from specimens taken from apple near Lawrence, Kansas. It has since been taken from the same host near Bentonville Arkansas.

General ground color semihyaline to yellowish white marked with reddish orange. Vertex with semblance of five white spots more or less surrounded with orange bands.

In November, 1930, spruce stands throughout a great deal of the interior of the Gaspe peninsula were found to have been partially defoliated by a sawfly. In some areas the greater part of the foliage had been eaten; about ten cocoons per square foot were found in moss and litter on the ground, beneath the trees.

The occurrence in Canada of that unique and interesting species, Thylodrias contractus Mots., which Felt (2) has dubbed “the odd beet1e”, is a matter worthy of note.

This species was first discovered in North America, in May, 1902, by Mrs. Annie Trumbull Slosson, who found the insects in a box of neglected entomological specimens stored in an old closet in her home in New York.

Male.—Length 2 mm. Black, shining. Antennal plumes black; basal antennal segment dull black, segments of flagellum brownish.

Thorax black, pleural membranes brownish, dorsum greyish pollinose; scutellum and metanotum dull black with faint pollen. Halteres dark brownish with creamy white knobs.

Several interesting records of Hemiptera are recorded from Utah in the following short list. The writer is indebted to Mr. H. G. Barber of the National Museum for naming the material.

As I was working over a series of Nemestrinid flies with Curran's key, certain variations at once became apparent. The series consists of 93 females of Rhyncocephalus sackeni, Williston, identified by Mr. Curran himself, and it seemed advisable to list the points used in the key and to assign therein the irregularities occurring in the flies, together with some variations in wing venation.
