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.

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.

The larva of Thyreus Abbottii possesses a peculiar interest to the Entomologist, as it is the only species of which the sex is supposed to be indicated by the coloration. Frequent reference to this is found in works of different authors, and nowhere have I seen any doubt expressed about the validity of the distinguishing markings between ♂ and ♀ (vide Harris' Ent. Correspondence, p. 284; N. Y. State Museum Report, p. 114; Can. Entomologist, 1874, p. 146).

In No. 4, Vol. ii, of the “Bulletin of the Buffalo Society of Natural Sciences,” Dr. H. A. Hagen gives an interesting paper on this moth and its parasites.

After a brief review of the previous literature of the species, Dr. Hagen says : “If columbia should happen not to be a distinct species, it must be either a variety of some other species or a hybrid of two species.”
