1. Danais archippus, Fab. A few migrants seen almost every yeat. June. Have never seen a locally-bred specimen.

2. Euptoieta claudia, Cram. Two specimens on Pine Creek, July, 1897, and June, 1900; probably migrants. Lacombe, June 29th, 1900 (Gregson).

3. Argynnis cybele, Fab. Not common; very rare in some seasons. In the hills, July and August; Lacombe, June 29th (Gregson). Mr. Elwes has seen this form and considers it correctly named. It resembles cybele that I have from Iowa, but is slightly smaller.

3a. [A. leto, Behr. Recorded by Geddes from Macleod. The record may perhaps refer to cybele.]

4. A. cypris, Edw. Not common. July and August. Whatever may be the correct name for this species, it is certainly distinct from anything else here listed.

Reading in the April number of the Canadian Entomologist, Mr. Heath's account of the plague of fleas in Manitoba, recalled what I had read in the Agricultural Gazette of New South Wales. It appears that in the Australian bush fleas are as great a nuisance as they are in some parts of Manitoba. A settler, who had suffered greatly from their presence, wrote to the Gazette that he had occasion to use tar paper in his dwelling, when he discovered that fleas would not stay in the house with it, and from that time he had no more trouble with fleas in his house, although they were as plentiful out of doors as ever. Last autumn, or early winter, one of our local members, on his regular visit to the Society's room, started the enquiry as to what was the best way to get rid of fleas, as his house had got overrun with them from having allowed their dog to sleep in the cellar. I thought of what I had then recently read, hunted up the number of the Gazette, found the reference, and showed it to him, when he said he would try it.

The effort to control the “white fly” of the orange (Aleurodes citri) by hydrocyanic acid gas, naturally suggested an inquiry into the respiration of these insects. The author was enabred to pursue this inquiry, while recently in Florida, under the auspices of trre Florida Agricultural Experiment Station.

The only account of the organs of respiration in the young of this family is a brief note with a figure in Burmeister's Handbuch, which is very incomplete and not entirely accurate. Some very interesting and quite unique features are presented by these insects, not the least of which are the breathing folds, that are very conspicuous structures, and have been heretofore incorrectly interpreted. The view suggested by Riley and Howard (Insect Life, 1893, Vol. 5, pp. 219–226), that the anterior folds represent the original division between the head and thorax, is the one usually accepted. In rearity they are wholly thoracic in position, being nearer to the pro-mesothoracic line than to the head-thoracic boundary, and they are by no means vestigial structures, but specially developed organs of respiration.

Mordellistena pustulata, Mels., was reared June 6th, 1899, from stems of Ambrosia trifida, Giant Ragweed, collected October 13th, 1898. From the same species of plant collected November 10th, 1899, this insect was reared April 4th, May 12th and 31st, 1900.

Mr. Coquillett has found larvæ of this species in plant stems, under circumstances that render it highly probable that they were feeding on Lepidopterous larvæ. The stems of the Giant Ragweed are populated by Lepidopterous, Dipterous, Coleopterous and Hymenopterous larvæ. In my case only by Coleopterous and Hymenopterous larvæ.

The supposed “types” of Guenée in the British Museum have been examined, with the result that some well-established names of Noctuids have been displaced by an uncertain determination. Guenée's collection, which I saw in cbateaudun during the lifetime of the author, is now with M. Oberthier, and should be looked through. But the only evidence we have which is vital is the original description; where this is inapplicable the name should not be used. Only on this evidence can we assume that any of the British Musenm specimens are the real types of either Walker or Guenée, because the collections have not been kept intact as Walker left them, and because no type labels were attached by the latter to the specimens. In these pages I have, I hope successfully, rehabilitated Mamestra lubens, and, by publishing the following translations, perhaps other undoubted names may be restored to their rights. I maintain, for instance, that whatever may be written on the subject, a name like Apatela subochrea should always be retained for the species, in reference to the contradictory opinions which have appeared in print. What we want is certainty in designating the object, and, when circumstances clearly admit of doubt and authors disagree, the sure title should be preferred in every case. There is now far more confusion as to specific titles of our Noctuids than formerly, when the current determinations were mainly supplied by me.

The following list of the Coccidæ found to inhabit Canada is complete, so far as the published records show, together with some other information derived from corresponding with Prof. Cockerell, Dr. Fletcher, and Mr. John Dearness. Much, however, has been obtained from material sent to me for identification. In reviewing the list it will be seen that Ontario has 25 species of Coccids credited to her; while Ottawa has 18; Toronto, 6; Quebec, 3; Prince Edward Island, 3; Nova Scotia, 4; New Brunswick, 2; and British Columbia, 6. One has been found in an ants' nest, 8 in greenhouses, and there have been 8 new species described from Canada. There are 46 species, 27 of which are native to North America, 14 are introduced, and 4 whose home is unknown, but which were probably introduced. The large majority of the species have been found by Dr. Fletcher, or at least have passed through his hands. Much credit, however, is due Mr. John Dearness, who has taken great interest in looking for these very injurious insects, and has sent me several very interesting species.

Head narrower, eyes nearer together than in Salda, ocelli approximate, frontal ridge weak, becoming obsolete at base of tylus, bucculæ enlarged; antennæ with the two distal joints incrassate, rostrum as in Salda, basal joints very thick, second elongate, terminal very slender. Prothorax bearing two very prominent conical tubercles on anterior lobe, which is narrow, cylindrical, not carinate anteriorly; posterior lobe short, carinate laterally, widening rapidly to humeri.

In the February number of the Canadian Entomologist I gave the results of an experiment in the exportation of a few of our native lady beetles to South Africa. I now have the pleasure of giving the resurt of an experiment in the importation of some South African lady beetles.

March 27th, Mr. C. W. Mally, Assistant Government Entomologist, sent me several specimens of Exochomus nigrmaculatus, and, quite a large number of two smaller, unnamed species. All of these attack more especially the Mealy bug, Dactylopius, in their native home. The consignment was made by simply fastening twigs of Oleander very badly affected with Mealy bug, to the bottom of the box, and putting the lady beetles among them. The package reached me April 23rd, and, strangely enough, there were but very few of the specimens that were not alive and active. The importation was thus an entire success.
