This list was commenced on page 291 of Vol. XXIX of this magazine. Since then another season has come and gone, and Mr. Heath, of Cartwright, has kindly submitted all his moths to me for names. Some good collecting has also been done by Mr. Marmont, at Rounthwaite. The result is, as will be seen by a perusal of the subjoined list, a very respectable addition to the Sphingidae and Bombycidae of this Province.

Collections made by Mr. Criddle, at Douglas, and Mr. Hutchinson, at Kinosota, have not been seen yet; they no doubt will yield some new or rare species, especially as both localities should be good ones. At Douglas there is a very large spruce and tamarac swamp, and Kinosota is close to Lake Manitoba, and has besides extensive forest lands in the district.

This subfamily is rather poorly represented in Arkansas, only eight of the thirty-one genera recognized by me as occurring in North America having been found within its borders, and only one genus, Orphula, is represented by more than a single species.

Mermiria rostrata, McNeill.—Has been found in the State, but its occurrence at Mackay, I. T., makes it altogether probable that it belongs to our fauna.

In answer to Dr. Butler's comments (Can. Ent. XXXI., p. 19) upon my revision of the species of Euchloé (Bull. Am. Mus. Nat. Hist., X., pp. 235-248), I could state that Dr. Butler may possibly be right in considering creusa (var. elsa), hyantis and lotta seasonal forms of ausonides, but with the present knowledge it is not possible to place them so, and for this reason I concluded it would be best to allow the species to remain distinct until more light could be obtained on the subject. At any rate I was certain that what we had labeled in our collections as creusa was not Doubleday and Hewitson's species, which Dr. Butler definitely asserts is my var. elsa.

While the Canadian species of this family are not numerous, they are of considerable interest, and because of the scattered nature of the literature, often quite difficult to identify. The present paper, while containing little that is new, will serve to bring together in conscise form the information necessary to enable the beginner to examine his material intelligently.

In the Leconte and Horn “Classification,” the following characters are used as defining the family: “Mouth-parts normal, palpi flexible, front and middle tarsi with five, posterior with four joints. Anterior coxal cavities open behind, head not strongly constricted at base, middle coxae not very prominent.

Lemonias Duryi, Edwards.—I have before me a ♀ taken by Mr. S. Macgregor in 1898 between Mesilla Park and the Organ Mts. N. M.; that is, in the exact type locality of the species, originally collected by Mr. Dury in 1881. The specimen expands an inch and a half, and is thus larger than Dury's but is otherwise the same. I do not know why Dr. Holland states (Butterfly Book, p. 230) that the ♀ L. Duryi figured by him is the only one known: Dury took several and Edwards described from both sexes.

Some time ago in examining our species of ant lions I noticed that our two large genera, Myrmeleon and Brachynemurus, could readily be separated by the position of the origin of the radial sector; in one much nearer to the base of the wing than in the other. The characters previously used for Brachynemurns, as the forked costal veinlets, the length of the tibial spurs, etc., had not been satisfactory; and the discovery of this distinction led me to examine the other forms of the family with a view to their better classification.
