As I was in the habit of sending to the authorities, for determination, only such as I had in duplicate, thereby avoiding the inconvenience of returning them, and retaining single specimens of a kind as a reminder of what at look for, and in most cases where to look for them, I found that in Micros single specimens accumulated rapidly. Having changed my location, I wished to finish up with the old material and begin anew.

Havin been asked by Sir William Dawson to look over two collections of insects which had been sent in in competition for a prize, I was delighted to find in one of them a speciment of this very rare moth.

Knowing that everything in connection with the capture of such a rarity would be of interest, I asked Sir William to ascertain from Mr. R. McDougall, the collector, all the facts that he could furnish in connection with such an interesting event, and I duly received, through Sir William, a letter about it, from which I extract the following account:-

“The moth was caught at Ormstown, Chateauguay County, and was the only one observed during the summer.

Mr. Scudder, in Butt. N. E., argues at length in favour of considering Proserpina as neither more or less than a hybrid between L. Arthemis and L. Ursula(called Astyanax). I differ from him, holding Proserpina to be a dimorphic form a Arthemis, just as Papilio Glaucus is a dimorphic form of P. Turnus.

Orchelimum gracile, n sp.— A slenderer and somewhat smaller insect than either O. vulgare or O. concinum, from both of which it differs in the form of its pronotum and of the ovipositor. The tubercle of the vertex is short, broad, and has the apex rounded. The tegmina and wings are of moderate length, very delicate in texture, and in the male furnished with an inconspicuous musical apparatus very similar in proportions to that of agile and longipennis. Legs slender, the posterior femora not quite reaching the tips of the closed tegmina.

The genus Pseudohazis, Gr.& R., has only two typical representatives so far known, one being Eglanterina, Bd., with the purple colouring, and the other the white Hera, Harr., from Utah's salt regions. Hera has to be considered a distinct species, for, aside from its white colour, its primaries are falcated, while those of Eglanterina are broad and blunt. All the rest of named insects are variations of Eglanterina,“Pica, Walk., being especially recognizable by its heavy black markings and black basal areas.

Junoniacœnia, Hubn.

Egg.—Spherical, a little flattened at the base, with about twelve vertical ribs running to the micropyle; colour, shining pale green; diameter; .5 mm.

First Stage.—Head rounded, black and shiny; width, .25 mm. Body sordid greenish, with long black hairs curving forward, arising from small lustrous tubercles. Feet concolorous with the body.

Psecadia delliella n. sp.

Expanse of wings, 21 mm. Palpi white, with the outside of the first two joints black, Head white. Antennæ brown, white above basally. Thorax snow white, with two black bands, one across the middle and the other across the scutellum.

But little attention has heretofore been given to the Acrididæ inhabiting Indiana by the working scientists of the State. No record of any published paper relating to them can be found, and it is believed, we suppose, that because Indiana lies next to Illinois, where Dr. Cyrus H. Thomas did much of his work, that most if not all of the species of the family found in this State are included in the two lists of the Orthoptera of Illinois prepared by him.

Xiphidium modestum, n. sp.—Related to X. saltans Scudd. and X .stricutm Scudd., from both of which species it differs in its smaller size, slenderer form and in colour.

Vertex or cone of the head not quite so broad and shorter than in saltans, its closest ally; pronotum with the sides less bulging, and not reaching as low as in that species.

Sitzus speciosus is the largest native ground-hornet, and its formidable appearance and great activity generally secure it undisputed possesion of the square rod where it happens to alight. It is from an inch to an inch and one-half in length; the head and thorax are brown, and the abdomen is black with six irregular yellow blotches.

In the Trans. Am. Ent. Soc. I offered a revision of the species of this genus, in which I reduced the number of species to five; but, from recent experience, I am of the opinion that this number will have to be still further reduced. I have bred a moth that forms an intergrade between P. elegans and P. fusca, and have noticed no difference between the larvæ that produces geminata and albipunctata.

Lamenia Californica, n. sp.

Form and size of L. vulgaris. Black, shining, densely pruinose; head, pectoral pieces, and legs fulvos. Length, 4 mm.

Front but little wider across the middle than next the vertex. Head fulvous, tinged with brown on the vertex, apex of the clypeus, margins of the cheeks, and on the front each side of the central carina. Eyes dark brown. Pronotum fulvous, more or less embrowned on the disc; propleura, base of the intermediate femora and the claws dusky or blackish.

The Great Salt Lake of Utah has been easily accessible for many years, and its shores have been visited by various entomologists; so that it seems strange that no one has hitherto published a comprehensive or even partial list of the insects occurring in that interesting locality. During the present summer, while on a short excursion to Utah with Mr. H. G. Hubbard, we had the opportunity of spending some time in the investiagation of the insect faune of the Lake.

Meigenia websteri, n. sp.

Female.—Head a little wider than thorax and abdomen. Eyes brown, very sparsely hairy; front and face not quite one half the width of head; front a little prominent; frontal vitta about one-fourth the width of front, brown, lighter behind where it splits on each side of the ocelli; frontal bristles in a single row, descending a little below base of third antennal joint, some fine hairs on sides of front outside them; two orbital bristles; sides of front with a slightly brassy tinge; sides of face moderately wide; a little less than one-half the width of the facial depression, silvery, bare; face slightly receding, facial depression silvery, facial ridges cliliate to a little below base of third antennal joint; cheeks moderately wide, cinereous, hairy, with bristles on lower border; vibrissæ inserted at a little distance above the oral margin; antennæ not as long as the face, blackish, third joint slightly reddish at base; second joint not elongate, bristly; third joint not widened, more than three times as long as the second; arista black, microscpically pubescent, thickened more than half its length, three-jointed, the second joint hardly elongate; proboscis, brown, fleshy, not so long as height of head, labella well developed, palpi well developed flavous club-shaped, thickened and curved at the tip, black bristly; occiput cinereous, gray hairy below, with fringe of black hairs on orbital margins.

Pyrgus pelagica, n. sp.

Habitat: San José del Cabo, Lower California.

Expanse, 1.25 inches.

Descripition.—Under side of palpi and head covered with whitish hairs; top of same blackish-brown gray; forehead with some whitish hairs mixed with the darker. Thorax and abdoment blackish above, end of abdomen shading into gray, beneath whitish. Legs covered with whitish hairs, brownish at end. Antennæ blackish, with small white annulations at abse of each joint; club above blackish, tipped with light brown, below light brown down to joint.

Philonthus quediinus Horn. A male specimen of this fine species was taken here As the anterior marginal puncture of the thorax is placed so unusually far behind the margin, and on a line with the three discal ones, the discal punctures are apparently four. In this speciment the singular bunch of bristles on the penultimagte ventral segment consists of about six, all differing in length, and rising from a small median pit resembling somewhat that seen in the male of some species of Dermestes.

The Dysderidœ is a small family of spiders occupying in a certain respect an intermediate postion between the Tetrapneumones and the Dipneumones; the openings to the tracheæ are just behind the lung-slits, so that they may appear to have four lungs. The eyes are six in all of our forms. The mandibles are not small, in Dysdera quite large. The male palpi are quite simple in structure.

It is forty years ago since Lederer used the male genitalia to group the European species of Agrotis. According to the latest general work on the subject, the 127 European species of Agrotus fall into nine groups, characterized chiefly by changes in the form of teh male genitalic appendages. The failure to correlate these European groups with the American subdivisions of Agrotis, prevents me from considering Prof. Smith's recent revision as complete, since I have demonstarted the near relation between the two faunæ exhibited by Noctuinœ of the Old and New World.

My collecting at Little Metis having been confined to July and August, my knowledge of the forms occurring there is necessarily very incomplete; but as the insect fauna of the Lower St.Lawrence seems to differ considerably from that of Ontario and the western part of Quebec, I venture to give a list of the species I know to occur there, and hope that in the event of my not going there again, some other entomologist will give us a list of additions.
