r have only examined the neuration of one of the species which I here place in this genus, but they are all evidently congeneric, and the neuration of L. lyonetiella while not that of L. cephalonthiella, nor of either of the three species figured Ins. Brit., v.3., does not differ therefrom more than they differ from each other. The limits of the genus are perhaps not so clearly defined as might be wished in respect to the neuration and the raised tufts on the primaries, but as the genus is at present recognized, the proper location of these species is in it.

The publication of the paper on this genus in the February number of this magazine, in its present form, was unfortunate, and resulted from a misunderstanding by the Editor of a letter addressed by me to him. The paper was prepared from specimens contained in Mr. Belfrage's first collection, and was sent by me to the Editor some months ago. Further study of that collection and of additional material, induced me to suppress some of the descriptions and to amend others, and with a view thereto I requested a return of that portion of the mss. Unfortunately my letter was misunderstood. and the wrong mss was returned to me, while the paper on Laverna was published.

Mr. George Norman has recently taken a number of the species of the genus Lithophane at Orillia. In a recent letter, Mr. Norman records the capture of petulca, ferrealis, disposita, Bethunci, semiusta, and “that lovely oriunda, a single specimen.” Mr. Norman also finds a number of specimens of a large light grey species allied to laticinerea, but differing from that species and cinerea in the position of the stigmata, the color, and the shape of the subterminal line. I propose to call the species Lithophane Georgii, after its discover.

Mr. George Norman has sent me specimens of a species of Agrotis allied to tessellata, which were taken at orillia, I propose to call the species Agrotis vennipellis. The male antennae are brush-like, eyes naked, all the tibiae spinose. The thorax and tegulae are dark brown; collar with a blackish shade in front, below which it is ashen.

Since the preceding portion of this paper, as well as much of that which follows in this and some following numbers, were placed in the hands of the Editor of the Can. Ent., I have received from Mr. Belfrage another collection of Tineina from Basque County, Texas, containing additional specimens of species found in the first collection, and several new species. The only species contained in this last collection which has been previously described from more western localities, and were not contained in the former collection, are Gelechia solaniella ? Cham. and strobisia iridipennella Clem. and Theisoa bifasciella.

Expanse 40 m. m. Length of body, 18 m. m. Palpi long and slender, the second joint light and contrasting, the third dark, tipped with light. Thorax as usual in the genus. Abdomen cylindrical, with slight white dorsal tufts. Anterior wings uniform dull gray-brown, sprinkled with black atoms; the usual black clear-cut transverse lines are obsolete, the subterminal line only is seen as a black diffuse shade crossing the wings; some basal black markings; ordinary spots black, very distinct, close together; the orbicular a round spot, the reniform a subiunate black mark; a series of black dots before the concolorous fringe.

Those of the members who accepted Mr. Jack's kind invitation to visit him on Dominion Day, left town on Thursday, the 30th June, by the 5 p. m. train, for Lachine, where they took the boat and had a delightful sail up the Chateauguay River as far as the Basin, where they were met by Mr. Jack, who conducted them to his beautiful residence, where they were warmly welcomed by the rest of his family.

In the Am. Nat., Sept., 1872, Mr. Scudder published an essay entitled “The curious History of a Butterfly,” in which it is stated that in two N. American species of the “genus Brenthis,” namely, myrina and bellona, occurs a phenomenon considered by the author to be quite unique among butterflies : there being two sets of individuals, each following its own cycle of changes,:apparently with as little to do with the other set as if it were a different species; each set having its own distinct seasons and thus giving rise to the apparition of two or three successive broods in the course of the year.

The following species were collected by Mr. Schwarz and Mr. Bela Hubbard, of the Detroit Scientific Association, among other most valuable scientific material, obtained during a recent visit to Florida. Megathymus yuccae (Bdv. & Lec.) Scudd.

The eyes are large and naked; caputal squamation of mixed flattened scales and hair. I cannot find any ocelli. The cylindrical, scaled antennæ are capitate, without terminal inflection or hooklet. The tibæ and tarsi are strongly spinose; hind and middle tibiæ with terminal claw.

Egg spherical, .04 inch in diameter, honey yelloW, shiny and smooth as polished glass; laid in straight rows. Larva, when first hatched,one eighth of an inch long, head small and black, body dark brown clothed with ten longitudinal rows of bunches of spreading hairs; dark brown on the sides, dark gray on the back. First moult somewhat increased in size, color unchanged. Second moult 3/8 inch long, dark sooty brown; hair dark brown on the sides, grayish brown above.

Since I am recently criticized for erecting new genera in the Sphingidæ as it is thought unnecessarily, I have put together some of my thoughts on the subject in the present Paper. In a review, the friendly spirit of which I most gladly recognize, Mr. Moschler speaks of my division of the old genus Smerinthus, which I have restrictcd to the type ocellatus, geminatus, &c.,and says in effect that since hybrids are known to occur between certain of the species, these could not be generically or tribally separated.

Expanse 34 m. m. Length of body 14 m. m. Eyes hairy; antennae of the male simple; villosity of the palpi coarse; thorax provided with the usual fore and hind tufts; abdomen short, stout and untufted; ground color of the anterior wings gray without ochreous or brown admixture, as in M. lorea Guen.; the ordinary spots are tolerably distinct, concolorous, black encircled, the reniform filled below with black, the clavifor small; the median lines are simple, black and conspicuous, the interior line perpendicular, forming a triangular projection above the orbicular spot, which it touches.
