Enarmonia Cockleana, sp. nov.— Palpi pale fawn, tipped with black, Front of head or face very pale fawn, top of head and thorax a shade deeper. Fore wing rich reddish chocolate brown, by refracted light, scales prismatic, like burnished copper. A broad fawn-coloured fascia from costa at inner third obliquely to dorsal margin beyond half. A second oblique fascia parallels the first, begins on costa at outer two-thirds, and ends at anal angle; this is broader on costa, and lower half is not so well define.

Tortrix conflictana, Walk.— Five specimens: Lethbridge, Macleod and Pine Creek; VII., 8, to VII., 13. Larger and the bands more suffused than Eastern specimens.

Tortrix argentana, Clerck.— Three specimens; Macleod and Lethbridge; VIII., 8 to 15. I have a long series of this species from Western America, south nearly to Mexico, and north to British Columbia, likewise a series from Europe, and every time I examine them I am impressed with the feeling that our American species differs from the European, but further study is required before deciding either way, in the meantime the European name can stand.

The only apology for publishing the following descriptions at this time, is that the names have been made use of in identifying speciments for Messers. Saunders, Winn and Yound, and that “MMS” species are the bete noire of entomology—effecutally locking up a species indefinitely, and prohibiting any one form referring to it in any way, no matter how common it may be or how interesting a life-history someone else may have worked out.

The following list of Micro-Lepidoptera taken in the Province of Manitoba, is published for the purpose of recording the distribution of species, as well as an incentive to the collectors of the locality to make more than ordinaly efforts to add to the number. The work that has already been done is most gratifying, and compares very favourably with local lists of many of the States, from which a great deal mor would have been expected.

Exentera apriliana, Grote.—Aweme, IV, 30, to V, 21; Beulah. Thirteen specimens. This is a particularly interesting caputre. Grote's descripiton is remarkably brief, and his generic description, occurring on the same page, is misleading on account of an error. He states: “Hind wings 7-veined, 5 wanting.” I know of no Tortricid genus in which 5 is absent; frequently 3 and 4 are coincident or stalked for their entire length, but even this is not the case in any one of these specimens; 3 and 4 are stalked from a quarter to a half.

Diastictis argyralis, Hbn.— Beulah, IX, 14.

Nomophila noctuella, Schiff.—Cartwright.

Loxostege chortalis, Grt.— Aweme, VI, 6, to VI, 19; Souris.

Diasemia plumbosignalis, Fern.— Aweme, VII, 1; Souris; Wattsview.

This species, described by Mr. A. Busck, in the Proceedings of the United States National Museum, XXXVII., P. 746, 1904, paper No. 1375, is Sciaphila trigonana, Walsingham. [Lepidoptera-Heterocera British Museum, Part IV., p. 22, 1879; Dyar's Catalogue, No. 5413; Smith's List, 1903, 5831.] The species is well figured by Walsingham, Plate LXV., fig. 7.—

Proteoptervx Willingana, sp. nov.

♂, 18 mm. Head, thorax, palpi, antennæ and fore wings, same shade of very light tan or pale brownish-fuscous, overlaid with a few blackish brown scales.

Palpi: outer joint short, obtusely pointed; tuft on second joint flattened and appressed, lower scales extending to outer end of outer joint. Head roughtly scaled. Eyes black with coppery reflection. Antennæ annulated with fuscous and brown. Thorax smooth.

This species was named by Clemens* from the larval habit and foodplant only. He did not publish a description of the moth, nor, so far as I am aware, has any one else bred it, until very recently Mr. Arthur Gibson rediscovered the larvæ on basswood.

Proteopteryx Willingana, Kearf.—Two additional specimens; Regina VII., 20. One strongly marked ♀ and one almost unicolorous ♂, the same as the types.

Ancyclis mediofasciana, Clem.—One specimen; Regina, VI., 18. Does not differ from Eastern examples; already recoreded by Dyar from Kaslo.

I am very much indebted to Mr. T.N. Willing, a Regina, Assa., for the privilege of working up a very interesting collection of Micro-Lepidoptera. It is particularly notable in recording a number of species that have hitherto been only known by the types, and especially so in establishing a wide range of territory to species that have been only recorded from California. Following this paper I have one in preparation on the same subject, from material collected in Manitoba by Messrs.

Aristotelia Youngella, sp. nov.—Head. antennæ, palpi, thorax abdomen and legs shining iridescent green. Basal half of front wing and outer half along costa black or very dark brown, heavily overlaid with iridescent green. The dark basal half is outwardly margined by the black ground colour, owing to absence of the iridescent scales at this point. All the outer half of wing, except the dark costal streak, is dull ochreous, inwardly margined by a pale yellow line, the latter adjoining the dark line of ground colour outlining the basal half.

Through the courtsey of Dr. Harrison G.Dyar I have had the privilege of examining and assisting in the identification of all the specimens of the family Tortricidœ collected and bred by him and his assistants during the past summer at and in the vicinity of Kaslo, B.C. A completed list of all species will be included in Dr. Dyar's comprehensive paper on his summer's work, which is in course of preparation. All of the species that appear to be unknown are described in the following paper. Prof. C.H. Fernald has very kindly read over the MSS and examined the types, and confirmed my generic determiantions, and in the case of one species made a correction, for all of which I am glad to acknowledge my obligation.
