Whether they fill the listener with a train of happy thoughts, as Gilbert White says, or whether they produce a sadness because the days of summer are nearly gone, as Dr. Harris asserts, the songs of crickets and other Orthoptera have, nevertheless, the merit of always being interesting. An insect that can sing—that has something to say—even though it be the same, night after night, enjoys a sort of individuality, and this lon discussion of the Katydids and the quiet murmur of the tree crickets, constitute one of the chief charms of our summer evenings.

Not unfrequently do I read of the capture of Southern Noctuidœ found in Canada and the Northern United States, with the added remark that the speciment was so fresh that it must have just escaped from chrysalis. These remarks are made while I am always (for ten or fifteen years past) saying that these are wind visitors, immigrants.

On PAge 114 of the present volume of Canadian Entomologist Mr. A. R. Grote in his “Note on Mistaken Identifications,” mentions Dr. Harris' record of the capture of Carabus auratus Linn, in Massachusetts, and implies that Dr. Harris has made an erroneous, or “curious,” identification. This, however, is not the case, and it would be impossible for so careful an observer as Dr. Harris to make a mistake about a species so well known.

The object of this note is to draw attention to a paper printed at Demopolis, Ala., Dec., 1870, in which I endeavored to reply to Mr.Scudder's objections to our determination of Hübner's Plate of calanus. I say: “The chances are against Hübner's having figured both sexes of the ususally unspotted T. inorata with the spotted secondaries of calanus nob.

In my paper on “The North American Genera of Anthracina,” which appeared in the last volume of the Can. Entomologist (pp. 157–159), I proposed the nave Velocia for those species of Exoprosopa which have four submarginal cells in each wing. Through the kidness of Dr. Williston, I have been put in possession of a paper by Prof. Camillo Rondani, entitled “Dipterorum Species et Genera Aliqua Exotica.” published in 1863 in the Archivio per la Zoologia, Vol, iii, and on pages 56 and 57 of this paper Prof. Rondani proposes the name Hyperalonia for the above group; this name being the earlier, must supersede the one proposed by me.

To have the specimens in a collection look well, and at the same time be in a condition such as to render their examination as easy as possible, it is necessary that they should be properly collected. The ordinary cyanide bottles prepared either with plaster of Paris, or sawdust, which are used for Lepidoptera and Coleoptera, do not furnish good specimens of Hymenoptera, and those collected in alcohol are less satisfactory.

In my own collection I labelled a form in which a slight dentation of the terminal band on primaries was perceptible (and which in this respect agreed with Boisduval's figure in the Species General, and with Abbot's of fuciformis) as H. diffinis. It differed from tenuis by a greater breadth of band, a perceptible apical stain, a somewhat brighter or ore yellow haired body. Whether this was Mr. Strecker's Aettira, I Knew not, since I was unacquainted with this author's work, having seen only his numbers on occasion.

I have found in various collecitons in Europe, both public and private, specimens of the moth of our Cotton Worm determined after Hübner as above. From a note from Dr. Staudinger, I gather that in his collectin the moth is so determined and as proposed by me. Were I now to propose to call this species by its synonym, Noctua xylina Say, I do not think any of the entomologists in Europe would agree thereto, or be governed by Dr. Hagen's reasons for the change.

During the past summer I collected at Dublin, Wayne Co., Ind., a number of Œdipodini that seem to be a long-winged variety of the above named species. A comparison of the dimensions given by Thomas and Saussure for D. carolina and D. longipennis with measurements taken from eleven of these specimens, will show what the difference amounts to.

On page 38 of the February number of last year's Entomologist, is a note, written by myself, concerning an injurious Saw-fly larva which had appeared in abundance in the neighborhood of Quebec. I preserved quite a number of the cocoons of the species, hoping to obtain the perfect insect from them. Some of the cocoons were kept in a box in my study, others in a tin case placed in the cellar, and yet others in a glass jar half filled with moist earth.

In order to illustrate more fully his forthcoming work on New England Butterflies, the undersigned offers for sale for Two Hundred and Fifty Dollars, that wonderfully preserved Fossil Butterfly, Prodryas Persephone, of Colorado. The accompanying cut gives a rude impression of it. Less than twenty specimens of fossil butterflies are known in the world, and this is by far the most perfect and best preserved.
