In a recent issue of the Canadian Entomologist, No. viii, Vol. vi, there appears from the pen of Mr. Scudder a paper on “The Linnean Signification of the Generic Term Papilio,” containing some statements on which I propose to offer a few remarks.

The data given by Scudder from Linné's works are-save some minor typographical errors-correct, excepting in two important points. On p. 144 he says “in the year 1846 the first edition of the Fauna Suecica was published, in which Linne for the first time treats of species, giving to them names in the language of the country,” (The italics are mine.)

Can there be two Antispila miners of the Dog-wood? Either there must be, and my specimens are specifically distinct from this species, or Dr. Clements' description is strangely erroneous in at least one particular, viz., the color of the fascia and streaks, which he says are golden in cornifoleilla, but which are silvery white in my specimens, all of which six in number–agree exactly in ornamentation, and all but one of which are bred specimens. The species of the genus generally resemble each other very closely, and some recognized species do not differ from each other more than my specimens do from Dr. Clemens' description.

Preparatory to a fresh edition of the “List of Lep.,” of 1868, a few memoranda of the necessary changes rvill be published.

Sesia uniformis, p iii. This species is distinct from thysbe, and has been noticed by Mr. Lintner in his valuable “Entomological Contributions.” Mr. Couper found it on Anticosti. This can not be Sesia ruficaudis Kirby, the description of which is given on p. 27 of the “Synonymical Catalogue” of 1865.

Since so much has been written upon the habits of our ordinary Leaf-cutting Bee, it would seem presumptuous for me to offer anything further in connection there with. But a few facts which came to my notice recently are sufficiently interesting and important to merit publication.

During the latter part of June, 1873, several cells, a half dozen in number, were sent to me by a friend, who had accidentally brought them to light while digging underneath the shade of a Spiræ corymbosa.

The following fragmentary notes are submitted to the readers of the Canadian Entomologist in the hope that they may assist in even a small measure in determining the number of this order occurring in the Dominion.

When in Canada I only incidentally captured Diptera, and the number I possess is very limited. I am indebted to F. Smith, Esq., of the British Museum, for the names of those given below.
