the river, it was quite numerous, especially in August and September. The last date at which I observed it there, was the 13th September, when it was still abundant, and I then captured a specimen apparently just evolved. I saw several individuals at Grenville, October 14th and 18th, and on my return to Montreal on the 19th of that month it was still rather numerous there. As the larva of this butterfly feeds on various species of Trifolium it is not to be looked for in uncleared districts, and in fact it is only to be seen around clearings and open places, where the clovers have been introduced either by accident or design.

4. Pieris oleracea, Harris (Grey-veined White). Described in the "Canadian Nat. and Geol." vol. 2, p. 347. Abundant throughout the whole district. First observed near Grenville, 14th May, and was then numerous in the woods of that township. It continued abundant up to the end of June, but was not seen afterwards till the end of August, when I observed a few worn individuals at Hamilton's Farm. This species also, had the habit of pitching upon the dead fish and offal lying round our camps, but never assembled in any great numbers.

5. Danais Archippus, Fab. (Storm Fritillary.)-Figured and described in the Canadian Nat. and Geol. vol. 2, pl. 6, p. 350. A single specimen, which appeared to have been recently evolved, was seen by myself, flying across the Rouge, a little above Silver Mountain, on the 12th August. The different species of Ardepias, which constitute the food-plants of the larva, are sparingly distributed in this district, and accordingly this butterfly is seldom met with.

6. Satyrus Portlandia, Boisd. (Pearly Eye.) First seen about the camp on the south side of Bevin's Lake, Montcalm, on the 2nd July, after which it was met with abundantly in the woods along the Rouge as far as Silver Mountain, near which on the 6th August, those seen were much wasted, and they soon afte entirely disappeared. The specimens collected agree tolerably accurately with Boisduval's figures and descriptions of Satyrus Portlandia. It is figured under the name of Hipparchia Andromacha. Hübner, in Say's "American Entomology," vol. 2, pl. 36, and in Gosse's "Canadian Naturalist" p. 246. In the latter work it is spoken of as very rare in the Eastern Townships, and Prof. T. P. Kirtland, says it is among the most rare of the butterflies of Ohio. Being generally supposed to be a southern species, it is not little remarkable that it should be so abundant

to the north of the Ottawa. I have also met with it near Mon

treal.

7. Hipparchia nephele? Kirby. Abundant amongst grass on Hamilton's Farm, from the 22nd August to the beginning of September, but all seen were much worn. It is a common species in hay-fields at Montreal and Sorel, and is described in "Fauna Boreali-Americana," p. 297.

8. Limenitis Arthemis, Drury. (Banded Purple). Figured in Gosse's "Canadian Naturalist" p. 220. First seen at Sugar-bush Lake, Montcalm, on the 26th June, after which it became the most abundant species and continued so until the end of July, when all observed were much worn, but lingered on till the middle of August. It frequently assembles in astonishing numbers round old lumbering camps, &c., congregating about the tea-leaves and other refuse lying about such places. On the 15th July, on the site of a lumbering camp and timber rollway, on the banks of the Rouge, about three miles above the Indian Village in the Township of Arundel, I saw the most extraordinary assemblage of butterflies I ever beheld, several hundreds of this species being congregated together in groups consisting of from twenty to fifty individuals in each, whilst many others flew around and rendered it difficult to arrive at an accurate estimate of their numbers; nevertheless I am convinced that I am within the mark, when I state that there were more than three hundred assembled within a space of a few square yards. This species is very restless and active when on the ground, constantly opening and shutting its wings, unrolling its tongue, and running to and fro very rapidly, and even when feeding is not easily surprised. It flies freely in cloudy weather and quite late in the afternoon. According to Prof. Kirtland it is a rare species in Ohio.

9. Cynthia cardui, Linn. (Painted Lady). Described in the "Canadian Nat. and Geol." vol. 3, p. 346. But one specimen was met with, which was on the 21st August, at Hamilton's Farm, where the common thistle (Cirsium lanceolatum), the food-plant of its larva, is plentiful about the fields.

10. Vanessa Atalanta, Linn. (Red Admiral). I observed a butterfly which appeared to be of this species, on the 24th June, at Sugar-bush Lake, Montcalm.

11. V. Antiopa, Linn. (Camberwell Beauty). Figured and described in the " Canadian Nat. and Geol.," vol. 2, p. 93. Rather common at Grenville on the 13th May; a few specimens were seen

in the Township of Montcalm in June, and near Silver Mountain on the Rouge, on the 12th of August.

12. V. Milberti, Godt. furcillata, Say. (Forked). Common at Grenville, 14th May, not seen again until July 10th, on the Rouge, after which it was observed occasionally at Hamilton s Farm, up to the 31st August.

13. V. J. album, Boisd. (Compton Tortoise). A common species throughout the district, from the 19th May to the end of September. I observed one near Grenville on the 18th October.

14. Grapta Progne, Fab. (Green Comma). Abundant everywhere from the 14th May to the middle of September. On one occasion an individual of this species pitched on my hand and I caught it between my fingers.

15. G. C. album, Godt. (Orange Comma). The species of the genus Grapta (popularly termed Commas, from the silver spots in the centre of the hind-wings on the under side, which resemble an inverted comma) are so subject to variation, that it is extremely difficult to determine them, unless they are reared from the larvæ. I, however, took several specimens of a species which I believe to be G. C. album along the Rouge in July and August.

16. Argynnis Daphnis? Cramer (Small Silver-spot Fritillary). First seen at Bevin's Lake, Montcalm, 2nd July, andfrom that date it was abundant all the way up the Rouge as far as Hamilton's Farm, at which place, on the 25th of August, I saw a specimen perfectly fresh, whilst many others were flying about in a worn condition. It was very numerous on the flowers of Asclepias incarnata, near the Indian Village on the 18th July. The last date at which it was observed by me was 12th September. I am of opinion that Boisduval was in error in considering A. Aphrodite, Fab., and A. Cybele, Fab. as one and the same species. There are at least three closely allied species of Argynnis inhabiting Canada, but nothing short of breeding each from the larvæ will satisfactorily separate them. Two of my specimens agree best with Cramer's figure of A. Daphnis, but a third differs considerably and may be another species. They are all too small for A. Cybele, Fab.

17. A. Myrina, Cramer. (Pearl-border Fritillary). First seen at Grenville 5th June. Common at Bevin's Lake, Montcalm, at the beginning of July, and at Hamilton's Farm up to the 31st August.

18. A. Bellona, Fab. One specimen taken near Mr. Thompson's clearing on the Rouge, in the Township of Arundel, on the 30th June. It was not again met with.

19. Melitaa Tharos, Cramer, Cocyta, Hübner, (Pearl-crescent Fritillary). First observed at Sugar-bush Lake, Montcalm, 29th June. In copula and rather worn 2nd July about Bevin's Lake. A few seen a few miles up the Devil's River, 14th July.

20. Thecla (?) A large Thecla was seen by me at the Huckleberry Rapids on the Rouge, 2nd Range of De Salaberry, on the 30th July, but I failed in my attempts to secure it, and could not recognise the species, nor did I meet with any other of this genus.

21. Lycana Americana, Harris (American Copper). Numerous from the 21st to the 31st August, on grass-land at Hamilton's Farm, where its food-plant, the sorrel (Rumex acetosella), abounds.

22. Polyommatus pseudargiolus, Boisd. (Spring Azure). Numerous on the 14th May, in the woods of the Township of Grenville. The males were extremely abundant, congregating round putrid fish on the shores of Sixteen-Island Lake, at the end of May; I saw worn specimens as late as the 2nd July, about Bevin's Lake. When in a canoe on Sixteen-Island Lake, one of these beautiful little butterflies pitched on my hand and remained there for some time.

23. Pamphila (?) Two specimens of a dingy grey species of Shipper were captured, one at Sugar-bush Lake, June 26th, and the other at Bevin's Lake, 2nd July.

24. Pamphila (?) One specimen of a Pamphila, resembling P.paniscus (Chequered Shipper) of Europe, was taken near Bevin's Lake, Montcalm, 2nd July.

Two or three other species of Pamphila were taken in the Townships of Montcalm and Arundel, and at Hamilton's Farm, in June, July and August, which I have been unable to determine, and which are probably undescribed species.

Heterocera,

SPHINGINA.

Sphinx. I captured two species of Sphinx on the Rouge, in the Townships of Arundel and DeSalaberry, in July, allied to S. kalmia, Abbot and Smith, and S. gordius, Cramer, but not agreeing satisfactorily with the descriptions of those species as given by Dr. Harris in his Catalogue of American Sphinges, (Amer. Jour.

Sci. vol. xxxvi). According to Mr. Walker, neither of them is in the collection of the British Museum. Dead fish appear to be very attractive bait for Sphinges as well as other Lepidoptera, one of the species above mentioned having been taken whilst hovering over a dead carp lying by the water side, and many others were seen under similar circumstances. On the 11th August, when camped on a low flat at the base of Silver Mountain on the Rouge, I obtained a Sphinx larva, which from my notes, appears to have resembled that of S. Kalmia, as described by Harris (vide Amer. Journ, Sci. vol. xxxvi, p. 295). It was light green, with seven oblique yellow stripes edged above with dark purple, on each side; head yellow, with a vertical band of dark brown on either side; caudal horn, blue, covered with small black tubercles, and tipped with black. It appeared to have been washed by the heavy rain which had just fallen during a violent thunder storm, from the soft maples (Acer rubrum), which almost exclusively surrounded the tents, and on one of which it was crawling. Another splendid larva was found on the 19th September, feeding on a bush of Myrica gale, growing on the shores of Green Lake, adjoining the Lake of Three Mountains, in the county of Ottawa, about five miles from Hamilton's Farm. The following is the description of it which I made at the time: "Deep olivegreen, covered with minute spots of white, edged with black; seven oblique pink stripes, edged above with black and below with pale yellow, on either side; caudal horn, black; spiracles, orange; pro-legs, yellow; a stripe of light green on each side of the head." The minute white spots surrounded by black, thickly covering the whole upper surface, gave it a striking and most interesting resemblance to the scurfy resinous dotted leaves of its food-plant, the Bog Myrtle or Sweet Gale. This beautiful larva changed to a pupa which unfortunately perished during the following winter. Smerinthus. I obtained two larvæ, belonging to this genus, under elm trees at Hamilton's Farm, on the 3rd and 4th September, of which the following are descriptions: No. 1, pale green, whitish on the back, with oblique stripes of white and dark green on the sides. No. 2, green, with oblique tuberculated stripes on the sides, and two tubercles on each of the second and third segments.

Trochilium. On the 25th June, at Sugar-bush Lake, I captured a beautiful and apparently undescribed species of Trochilium, sitting on the blossoms of Viburnum opulus which were
