In 1806, Hübner, as we have seen, printed for his own use and in order that it might be submitted to certain competent persons, to be examined and judged of, the sketch of a plan for the arrangement of the Lepidoptera, called the Tentamen, &c.; and this sketch “was afterwards enlargcd and publishcd as the verzcichniss bekannter schmetterlinge,” as stated by Geyer, Thon's Archir, vol. 1, p. 28, 1827.

The simple fact which Mr. W. H. Edwards published in this journal last May has thrown great doubt over the relationship of all the American species of Cyaniris. From eggs laid in September, 1874, by C. Pseudargiolus, he reared in the following February C. violacea. From this fact he is led to conjecture that in W. Virginia, where his experiments were made, C. neglecta may prove to be a goneutic form of the same species, reducing the entire series in that district to one.

Soon after the issue of the “Systematic Revision,” and while I was trying to master the intricacies of its analysis, it occurred to me to tabulate the generic descriptions in some family, if, haply, I might thus discover the exact points of discrimination, By chance I took first the tribe Adolescentes, producing the table which accompanies this paper. In this table, if any expression or word which could distort the obvious meaning of the author, has been omitted or wrested from its proper connection. such change has been through inadvertence or mistake.

Some years ago I proposed the generic name Glaucopsyche for a group of blue butterflies of eastern N. America having a glaucous sheen to the upper surface of their wings; I had not then recognized its strictly generic alliance with a group of similar forms in Europe and on our pacific slope, which do not all possess this peculiarity, and to which the older generic name Nomiades Hübn. must be applied. A recent study of their common structural features, however, shows that GlacoPsychw can no longer be retained.

Rev. Cyrus Thomas, in his Acrididæ of North America, page 132, says: “There are no permanent characters by which to distinguish alcoholic specimens of Œdipoda corallipes, Haldemanii, paradoxa and rugosa from each other.” He therefore considers them the same. Probably Œ. discoidea might be considered as another as another variety of the same. This much named grasshopper is abundant in Nebraska from the middle of June to about the middle of August.

The species is closely allied to C. polygama Guen. Its distinctive features may be more clearly appreciated by a differential cotnparison with that species. The basal region is conspicuously and broadly shaded with black, deepening toward the anterior transverse line ; in polygama, shaded with ferruginous. The anterior transverse line is moderately oblique in its general direction, tending to the posterior third of the internal margin, geminate, distinctly separated by white below and slightly above the submedian : in polygama the line is quite oblique, tending to, or very near to, the internal angle; preceded below the submedian by gray and ferruginous scales.

My attention having recently been drawn to the “Historical sketch of the Generic Names Proposed for Butterflies, a contribution to Systematic Nomenclature, by S. H. Scudder, Salem, 1875,” in which some hundreds of names have for the first time been advanced, I was led to investigate for myself the sources whence part of them were derived, especially the works of Hübner.

There is not in the whole group of caterpilrars a more innocent and harmless-looking object than the larva of Lagoa opercularis–especially just previous to the fourth moult. As it reposes curled upon a leaf, with its long, wavy, white silken hairs the sport of the slightest zephyr, it resembles nothing so much as a tuft of the finest white cotton, and seems almost to invite the touch of caressing fingers.

During the season of 1875 I collected Noctuæ near Orillia, in the Province of Ontario. The locality where I resided was the Couchiching Hotel, a place of great beauty, situated on a wooded isthmus dividing Lake Couchiching from Lake Simcoe.

From the varied nature of the ground, enormous forest tracts, swamps, etc., I fully expected the locality would have been more productive in insects than my last year's place of sojourn, St. Catharines, which was, comparatively speaking, very poor and with very little timber. In this I was much disappointed, possibly owing more to the bad season than to the locality.

Last year I observed a female comyntas depositing eggs upon Desmodium Marilandicum Gray, a common and troublesome weed in this region, called “shoestring” by the country People, from its toughness of stem,and bearing a sticking burr in the fall. On 9th July, 1876, I set a female in a bag over a stem of this plant, and several eggs were laid on the tender tenlinal leaves. Mr. Mead noticed that this butterfly laid also on red clover, and a number of eggs were obtained by the same process, on the 13th July, deposited on the young leaves and on the flowrets of the head.

Eyes naked, tibiae unarmed, tufting of body obsolete, so that it approaches oligia, but is stouter than those species. Fore wings light gray. basal line black, distinct; t.a. line geminate, black outwardly and white inwardly, irregular; t.p. line geminate, produced above the reniform, curved outward, joining the reniform inferiorly.

Elytra and wings longer than body; elytra spotted; wings blue at base, gradually merging into black.

Female–Vertex broad; middle foveola circular, open in front with a slight median carina; frontal costa rather narrow, somewhat expanded at ocellus; sulcate, expanding at lower extremity. Lateral costa nearly parallel to frontal, Median carinn of pronotum crested, as in Œ Carolina, only much higher ; cut in front of middle by last transverse incision of pronotum.

In Vol. 4, p. 137, of the Canadian Entomologist, Mr. Grote first published a description of the large and characteristic Tineid above named. The imago has been very common with us for several years, but until the present season its larval history had eluded my investigation.

Early in April I found among the roots of a bit of white clover sod a very active and singular larva, whose long and rather sprangling thoracic legs gave it, at first glance, the appearance of a Coleopterous larva. A second look, however, discovered the characteristics of a Lepidopteron of which the following description was taken:

Length, 0.75 inch.; diameter greatest at head and 1st joint, slightly tapering thence posteriorly.

Taking into consideration the great difference in the lives and habits of the orders in question, I do not think the interbreeding of species of the genus Tetreao is any strong proof of the correctness of Dr. Hagen's conjecture. Robert Mudie, in his “Feathured Tribes of the British Islands,” speaking of Tetreao tetrix, says: “During the latter part of autumn and winter the males live together in flocks and in a state of the most perfect harmony
