On June 25th and 26th an old pasture supporting a thrifty growth of white spruce from 3 to 10 feet in height was inspected for spruce budworm injury. Very few budworm larvae were found but large numbers of Zeiraphera larvae were present. In the course of the study it developed that these were chiefly Z. ratzeburgiana with about 40% Z. fortunana. An older pasture adjoined and the growth was 15 to 25 feet in height. Here the relation was reversed. Z. fortunana formed over 75% and on the larger trees Z. ratzeburgiana was not found at all. No attempt was made to separate the larvae, and these figures are based on a study of the moths. In the case of old pastures where the small trees and reproduction were absent only Z. fortunana was found. Where the young growth was just taking possession and ranged from 3 to 8 feet, Z. ratzeburgiana was the dominant species.

Color pattern: Strikingly cross-banded throughout. Vertex, white or suffused wit11 yellow. Anterior two-thirds of pronotum, orange-red ; posterior third, white. First tegminal band occupying bases of tegmina to a point on costal margin slightly caudad of tip of scutellum, deep orange-red. Second band, white, extending to middle of clavus Third band, dark orange-red, about as wide as length of costal plaque; connected narrowly along costal margin with first tegminal band. Fourth band, white; rather narrow. Fifth band, golden yellow; somewhat wider than the fourth in middle; much wider at costal margin; margins uneven. Sixth band, white or transparent; narrower than the fifth; extending almost to cross-veins. Seventh band, smoky black; occupying rest of tegmina. Cross-veins, whitish ; most of base of cell M4, transparent ; costal plaque, purplish red with a white spot in either end; dorsum of abdomen and most of ventral surface, black or dark brown with the exception of the face between the eyes which shades off into a bright red band marked by several small white spots.

In the Fifty-sixth Report of the Entomological Society of Ontario, Mr. H. L. Viereck records a queen of Bremus kincaidii (Cockerell) from “Winter Ft. [specimen is labeled Winter H], Melville I [slandl, July 20, 1909 (F. C. Hennessey).” Due to the kindness of Dr. J. McDunnough this specimen was sent to me for examination. It proves to be either an unusually small queen, or a worker, of Bremus hyperboreus (Schonherr).

It is quite evident that this species has been wrongly identified in most collections owing to the fact that Williston erroneously placed his C. obscuripennis as a synonynl of brachyrhynchus. In Williston's table of species (Trans. Con. Acad. Sci., vi, 390) obscuripennis goes into couplet 2 under the caption: “Third joint of the antennae distinctly shorter than the second.”

Male. Intermediate in maculation between glaciana Moesch. and bipartitana Clem. Basal area dark black-brown, outwardly angulate in central portion of wing; antemedian whitish band broad on the costa, more or less perpendicular, with a few dark strigae; median dark band much as in bipartitana; whitish terminal area also much as in this species with three dark costal streaks and a small dark apical spot; slight dark reticulations below apex and a narrow dark patch at middle of outer margin (only evident on right side). Secondaries smoky. Expanse 18 mm.

The following notes have accumulated while collecting and naming species of Miridae during the past ten years. The records are chiefly of species where the distribution is new or of special interest, or to give data on host relationships. I wish to take this occasion to acknowledge the assistance I have received from several botanists who have from time to time determined plants for me.

This paper is to record the discovery of a mayfly nymph of very surprising form. It comes from the Ogden River in Utah. I collected it along with other aquatics on a hasty trip to that river, just before leaving Utah in July, 1926.

A collection of mosquitoes taken in Baffin Land, in 1925, by Mr. J. Dewey Soper, of the Department of Mines, has been received, recently, from Dr. R. M. Anderson of the Victoria Memorial Museum, Ottawa. The collection consists of eighty-four adults, two of which are males and the remainder females, and ten larvae. These specimens are of particular interest in that they are the first to be received from this island, and add to our rather scanty knowledge of the mosquito fauna of northern Canada. The collections were made on the east side of Nettilling Lake, the larvae being taken on June 28, and the adults on June 30 and July 9, 17 and 22.

During the summer of 1926, while collecting in Orillia, numerous small flies were observed on old fence posts in the hot sun. It was presumed that they represented some common species of Agromyzinae and only six specimens were captured after much difficulty, four of these proving to belong to a beautiful undescribed species of Mallochiella. In Melander's key to the Milichiinae (Jour. N. Y. Ent. Soc., XXXI, 1913) the members of this genus trace to Hypaspistomyia Hendel, an Asiatic genus, but the oral margin is not retracted. The carinate lunule is variable both in size and color in M. halteralis Coq. but always separates the antennae.
