of ringed and golden plovers, great abundance of snipes, plenty of small game, as starlings and wheatears, would furnish work for many barrels; not to speak of the multitudes of sea-fowl. On the whole, the scientific ornithologist, as well as the mere sportsman, will find both a varied and extensive field in Ultima Thule.

I shall conclude with a list of the arrivals and departures of our summer birds, as far as I have been able to ascertain them; the arrivals and departures of our winter species shall also be communicated to 'The Zoologist.'

The puffin almost always leaves on the 23rd of August. I have not been able to ascertain the exact time of arrival or departure of the Manx petrel (Procellaria Puffinus), as this bird comes towards the shore very quietly, and is rarely seen during the day; it seems later in its arrival than any of those I have mentioned. The Mammalia and fishes of Shetland will form the subject of another paper, and complete our vertebrate Fauna.

The Edible Frog. Through the kindness of Mr. Gray we are enabled to present our readers with a figure of one of the edible frogs mentioned by Mr. Bond, in a late

communication to 'The Zoologist,' as having lately been taken in Cambridgeshire, and deposited in the British Museum (Zool. 393).

Notes on Lepidopterous Insects. By EDW. DOUBLEDAY, Esq. F.LS. (Continued from page 198).

Genus.-HETERUSIA, Hope.

Heterusia Risa. Above: anterior wings olive-green, with a broad transparent yellow fascia before the middle, margined, especially externally, with black, over which however numerous blue and green scales are sprinkled. Posterior wings pure yellow, the base slightly shaded with blue and black, the apex broadly deep black. Below: the yellow band of the anterior wings is much wider than above, and all the wings have a curved fascia along the outer margin, and the extremities of the nervures are glossed with blue. Head and thorax above, green, the latter tinged with blue towards the base. Abdomen above yellow, the base blue, the apex olivaceous, the sides with a row of black dots; below olive, the segments margined with whitish. Expanse of wings, 2 inches, 6 lines.

Inhabits Nepal. In the British Museum.

Het. Edocla. Above: anterior wings nigro-fuscous or deep chococolate-brown, with an olive hue in certain lights, traversed before the middle by a broad, macular, whitish band, a spot at the base, one on the disco-cellular nervure, and nine others which form a flexuous series near the outer margin, also whitish. The nervures, where they traverse the macular band, are of a brilliant blue, and there is a more or less distinct shading of the same colour round all the markings. Posterior wings black, glossed with brilliant blue towards the outer margin and along the extremities of the nervures. The anterior margin

is pale, and there are four indistinct pale dots near the outer angle. Below all the wings black, the markings as above but more distinct, especially the four pale spots of the posterior wings. The anterior

margin of these wings wants the pale colour, but has a yellowish dot just within the discoidal cell. Antennæ black glossed with blue, head and thorax fuscous shaded with olive-green, the former with a tuft of brilliant blue scales between the antennæ, the latter glossed with blue at the sides, and marked anteriorly with two white dots. Abdomen above luteous, the two basal segments of a splendid blue, the sides marked with a row of black dots; below black, all the segments mar: gined with whitish. Expanse of wings, 2 inches 9 lines.

Inhabits Sylhet, in Bengal. In the British Museum.

Het. Edea. P. Edea, Linn. Syst. Nat. ii. 757; Clerck, Icon. t. 41, fig. 2. Acræa? Edea, Godt. Encyc. Méth. ix. 236, no. 19. This species, which Linnæus described as a Papilio, and which Godart, who had never seen it, thought might be an Acræa, may be at once known from the preceding by the broad whitish or yellow band of the posterior wings, which, commencing on the anterior margin, spreads across the disk so as to occupy more than half the inner and a portion of the outer margin. The space beyond this band is of a most brilliant blue, with four or more white and five jet black spots, the margin itself being narrowly edged with black. The anterior wings also

differ from those of H. Edocla in having two additional white spots near the apex, and the blue gloss around the markings is more distinct. These characters will be seen in the accompanying wood-cut, from a specimen in the British Museum, sent by Mr. Stainsforth from Sylhet.

Het. tricolor, Hope. The British Museum possesses a pair of this species, and I am thus enabled to correct an error in Mr. Hope's figure and in his character of the genus, though for some time I have hesitated as to whether or no I could consider them identical with Mr. Hope's insect, having been assured by Mr. Westwood that the antennæ in that individual were undoubtedly setaceous. This was about a year and a half since, when I first exhibited at the Entomological Society the specimen of H. Ædea now in the Museum cabinet, and after pointing out its identity with Clerck's figure, expressed an opinion that it was congeneric with H. tricolor. Since that time, however, Mr. Westwood, probably forgetting the precise words of my remarks, has stated that H. tricolor, Hope, is synonymous with P. Edea, Linn. Although this statement is incorrect, it confirms my opinion of the two insects belonging to the same genus, and leads to the inference that Mr. Westwood has found that the antennæ, as figured in the Linnean Transactions,' are erroneous.

The truth is that the antennæ of this genus offer a structure as singular as any which I know to exist in the nocturnal Lepidoptera. In the male they are strongly bipectinate; in the female they are much longer than in the male, the pectinations, except at the apex, so short as to be hardly observable, but at the apex they are longer and lamelliform, forming when closed a compact club, but evidently capable of being expanded, as in the lamellicorn beetles. On this, however, I have some further remarks, but must defer these to a future time, when I shall point out the tendency to this structure in the genera Chalcosia, Erasmia and Amesia.

Genus.-PAPILIO.

Papilio Turnus, L., and P. Glaucus, L. These insects in reality are but one species, the latter being an obfuscated variety of the former.* This fact was pointed out to me by Mr. D. Dyson, of Manchester, an intelligent young man, originally a weaver at Oldham, whose zeal for Entomology carried him out last year to the United States. To myself the idea had never occurred, but I have only once or twice seen P. Glaucus on the wing, and then soaring above the underwood, which I had only seen P. Turnus occasionally do, and which I imagined to be the constant habit of P. Glaucus, L. In this I have found

* Boisduval perhaps suspected this. He thrice, in his description of P. Glaucus, compares it to Turnus, and adds in a note, "Ce beau Papillon, malgrè sa couleur noire, a beaucoup de rapports avec Turnus sous ses premiers états."

range

from other sources that I was mistaken, and have ascertained the of P. Glaucus, L., to be more northern than I had believed. The larva and pupa of both as drawn by Abbott are identical. Henceforth the name Glaucus must be dropped. The merit of the discovery belongs not to any scientific naturalist, but to one whose only book has been the best of all books that of Nature.

Genus.-LOBOPHORA.

Lobophora polycommata. There is a misstatement in Mr. Humphreys' 'British Moths,' relative to a specimen of this insect in the British Museum, and which is figured in that work. Mr. Westwood states that this specimen belongs neither to the genus nor the species. Now the correct figure is from the Museum specimen, the incorrect one from Hubner, the error being in copying Hubner's figure, Geom. 89, which is A. Æscularia, by mistake for his fig. 90, which is L. polycommata. Of this fact Mr. Westwood is well aware. reference to the figure was reversed I cannot say.

EDWARD DOUBLEDAY.

Note on a remarkable Variety of Hipparchia Galathea. At the latter end of last July I captured a very remarkable variety of the common Hipparchia Galathea, in a field on the heights between Dover and Walmer. The specimen is a male, of a clear milky white colour, and has not, on either the upper or under side of its wings, the smallest speck of black. Its thorax, abdomen and palpi are also entireiy clothed with white. The varieties of this insect heretofore described appear to have been more than usually suffused with black or dark brown. My specimen so decidedly agrees with Galathea in form, that I have no hesitation in referring it to that species, which was very abundant at the spot. It is in perfectly fine condition.—Thos. Marshall; King William St., City, November 4, 1843.

Note on a singular Variety of the large Cabbage Butterfly. of an unusual variety of a male Pontia Brassica. It was captured in a garden in Leicester last

year, and is now deposited in our local cabinet at the museum of the Philosophical Society. J. Plant; Leicester, January 17, 1844.
