In the Report of the Entomologist and Botanist to the Dominion Experimental Farms for 1905, at pages 179 and 180, considerable space is given to a discussion of an outbreak of a large noctuid caterpillar, which appeared in considerable numbers in Canada during 1905. Complaints of injury by this insect were received from a wide area, extending from Nova Scotia as far west as Lake Superior. During July many kinds of plants in gardens were attacked by smooth cutworm-like caterpillas, which when small were greenish in colour, having the body divided into two equal areas above and below the spiracles by a wide black stigmatal band.

When seven years ago I had the honour of occupying the Presidential chair of this Society, I ventrued in my annual address, as some of you will doubtless remeber, to suggest the formation of a North American Entomolgists' Union on similar lines to those on which the American Ornithologists' Union has been so successfully carried on; and in my second address the following year I again returned to the subject.

1. Chœtopsylla setosus sp. nov.— Nearest to Ch. ursi, Rothsch. (1902), but easily recognized by the shape of the abdominal sclerites and the tarsi.

Head.—The labial palpus consists of about ten segments, reaching beyond the trochanter, while in ursi there are seven or eight segments only. There is one row of four or five bristles before the eye. The occiput bears two or three hairs behind the base of the antenna, a lateral row of four or five bristles in the centre, and a subapical row.

The purpose of this article is to place before the fruit-growers and all interested in practial entomology, the main facts regarding the lifehistory, habits and appearance of the Oyster-shell Bark-louse Scale, and of the scales which are often mistaken for it. The damage done by this scale of late years has attracted so much attention, and so many enquiries have been received concerning the best methods for its eradication, that it is hoped earnest efforts will be made at once by all concerned to get it under control.

Who is not interested in the insects that persist in living in our homes as unwelcome guests? Some of these intruders are blood-thirsty creatures, and torment the bodies of their helpless hosts; some confine their attnetions to the carpets, woollens, and upholsters, and others are partial to the pantry, but all are heartily hated by the industrious housewife.

Hymenopterous parasite.— On April 13th, 1906, chrysalis No. 112 gave birth to an ichneumon fly, which Mr. D.B. Yound has kindly identified for me as Anomalon pseudargioli.

In most parts of temperate North America the true Dragon-flies are among the most conspicous members of the insect class in any community where water is at hand. Strong of flight, quick as a thought in their darting movements, wary in the highest degree, they are usually well known to all by sight, yet not often captured by the amateur collector unless he takes the time to devote his special attention to them at some favourable place.

488. Hydriomena quinquefasciata, Pack.— Veru common. Middle July to middle Aug. Exceedingly variable. The specimens that I have from the mountains (Banff) are duller in colour than those taken nearer Calagary, with less green. Mr. Taylor says: “It is best for the present to use the name quinquefasciata, Pack., for the moth we have been calling sordidata. It is probabaly the same as the sordidata, Fabr., of Europe (but a good variety), but it is not the sordidata of Packard's Monograph, which I think must bear Packard's name, nubilifasciata”.

The genus Incisalia was proposed by Minot in 1872, to separate from the unwieldy genus Thecla thos small butteflies which, on a basis of general similarity of structure in teh imago, seemed to be most intimately related to Hübner's niphon, which stands as the type.

The forty-third annual meeting of the Society was held in its new quarters at the Ontario Agricultural College, Guelph, on Wednesday and Thursday, October 10th and 11th. The chair was taken by the VicePresident, Dr. James Fletche, Entomologist and Botanist of the Dominion Experimental Farms. Among those present were Mr. John D. Evans, Trenton, the retiring President; Mr. Henry H. Lyman, Montreal; Mr. Arthur Gibson, Central Experimental Fram, Ottawa; Mr. C. H. Yound Hurdman's Bridge; Dr. Brodie, and Messers. C. W. Nash, J. B. Williams and Paul Hahn, Toronto; Mr. G. E. Fisher, Burlington; Mr. J. Fred. Smith, San José Scale Inspector for Ontario; President Creelman, Professors Hutt, McCready and Bethune, Messer. Jarvis. Eastham, Howitt, Zavitz and Pearl, of the Ontario Agricultural College, and a large number of students from both the College and the Macdonald Institute.

The following list of Odonata is mainly the result of four seasons collecting in various parts of Ontario, but chiefly in three localities, viz: Toronto, De Grassi Point, Lake Simcoe, and Algonquin Park.

Although most of the material was collected by the writer, the list has been considerably lengthened by the records of captures made by other collectors. Among these should be mentioned the collections of Dr. Wm. Brodie, in the Educational Dept., Toronto; many specimens taken in Algonquin Park by Prof. Macoun in 1900, and by Mr. Paul Hahn in 1903–4; a considerable number from the collection of the Biological Dept. of the University of Toronto, consisting chiefly of alcholic specimens of nymphs and imagoes taken at the Biological Experiment Station at Go Home, Georgian Baym and a few collected and presented to the Department by the late Mr. R. T. Anderson; and finally, a small collection from Thessalon, Algoma, belonging to Miss Rounthwaite, of Toronto.

In the revision of my Manual of North American Diptera, now in press, it has been necessary for me to examine ciritically the recent publications on the classification of the Culicidæ. Although I have never ceased to be an interested reader of dipterological literature, I was hardly prepared for the flood that has nearly swampted me in the attempt to reach terra firma.

Time of flight.—Species single brooded; butterflies to be found during late April and early May. I have taken the male as early May. I have taken the male as early as th 11th of April, but usually the first imagoes appear about the 20th. They become abudant by the first of May, after which time the females may be observed oviposting, and the males rapidly disappear. After May 10th worn individuals only are seen, some of which may endure even to the end the first week in June.

Some years ago Mr. J. M. Espin, of Guantanamo, Cuba, sent to Dr. L. O. Howard for names some parasitic Hymenopetera, among which I indicated a new genus, but which I neglected to describe. As Mr. Espin has rcently written about it aand desires its early description, I submit the following:

Neslinoceras, new genus.

I have carefully separated out my material by Mr. Pearsall's latest (Can. Ent., xxxviii, 33, 1906) and find all the forms before me. I cannot agree that the arrangement in final. In the first place, in describing the genus Nomenia, Mr. Pearsall mentioned as type 12-lineata, Pack., which he now transfers to EuchŒca, and makes a new name, unipecta, Pears., for the types species. This strikes me a contravention of the rules.

My last paper, npholding Dr. Hulst's determination that E.perlineata. Pack, is the above species, was intended also to convey the idea that until we knew positively that he was wrong it was better to accept his decision. Nor was it my desire to belittle the judgment of Mr. Prout, as I expressly stated.

Shortly before the destruction of my laboratory in 1903, I began to study some of the young females of several species of Coccidœ, for the purpose of determining if there were any constant structural characters present that would enable one to identify the adult female scale, and if there were any characters could be used in the classification of the several genera.
