In connection with our studies on the Oriental fruit moth, large numbers of the insect are reared in the insectary on apples. The fruit moth eggs are placed on apples in closed containers such as No. 10 tins, and when the larvae are mature the majority of them come to the top of the containers and are placed on strips of corrugated paper in lantern globes for pupation and emergence.The remaining larvae are allowed to pupate and emerge in the rearing containers.

The hemlock borer (Melanophila fulvoguttata Harr.) belongs to a buprestid genus, the larvae of which bore in the bark and cambial area of the stems of conifers. They generally breed in trees which have been weakened. injured, or recently felled. Several species, however, including fulvoguttata, are reported to be capable of attacking and killing healthy trees and doing a large amount of damage. In other words, they belong to that class of cambial feeders which normally finds conditions most favorable when the host is about to die, but occasionally appears to be capable, when numerous, of breeding in healthy trees which would otherwise live. They are faculative tree killers.

In the Canadian Entomologist (1882 and 1883) Marten describes 7 species of Tabanus from the western United States of which the location of the types is unfortunately unknown. Certain characters now considered essential for comparative analysis were not adequately treated by him and as the descriptions were apparently based on damaged specimens in 2 instances, and on very restricted numbers in others, some confusion has arisen as to the identity of certain of these species.

As our knowledge of the western Ephemerid fauna, particularly in its nymphal stages, increases, cur conception of the individual species becomes more accurate, necessitating in some instances corrections of previous statements, and enabling us to differentiate closely allied species in various groups which here-tofore had been lumped under one name. The basis for the following notes has been the rearings carried on by my assistant, Mr. A. N. Gartrell, in the Okanagan region of British Columbia in 1934.

In an attempt to discover the native hosts of the parasites of the oriental fruit moth (Grapholitha molesta Busck) the larvae of a considerable number of microlepidoptera were collected and reared. The economic results of the work have been1 presented by the writer in a previous paper; the present paper comprises a list of the lepidoptera which were reared, with their food plants and parasites. The lepidoptera were determined by Dr. J. McDunnough of the Entomological Branch, Ottawa, and the hymenoptera by Mr. G. S. Walley of Ottawa and the specialists of the United States Bureau of Entomologym, Washington.

Among the material sent for identification by Mr. J. L. Sperry was a small series of what appears to be a new species of Pherne; at any rate the specimens do not agree with any of the three species at present listed under this generic name and figured in the Barnes and McDunnough “Contributions” III, Pl. XV, figs 7, 8. 14. As is usual the antennae are bipectinate in both sexes, the pectinations in the female being distinct but much shorter than in the male; the palpi are distinctly shorter than in subpunctata Hlst.; the apical portion of the outer margin of primaries is less excavated and the angle at vein 5 less sharp than in the other members of the genus.

In 1924 (Proc. U. S. N, M. Vo1. 64, Art. 20, pp. 4-6) Cushman reviewed the North American species of Cidaphus pointing out diagnostic characters for the separation of C. paniscoides from two species which he described as new under the names C. occidentalis and C. australis. At that time the only Canadian record for a member of the genus was that of the female type specimen of occidetalis from Revelstroke, B. C. The distribution given for paniscoides, N. H., N. Y., Pa. and Md. indicated that this species also probably would be found to occur in Canada.
