The genus to which this very interesting species belongs differs so widely from the rest of the Cynipidæ that it has been separated from the them as a sub-family, under the title Ibaliinœ. Its members can be readily recognized by the cultriform abdomen and more strongly veined wings, as well as by their greater size. The cultriform—i. e., knife-shaped—abdomen is in itself remarkable enough to attract the attention of all who may chance to see the insects.

The first to express this belief and put it in a tangible shape before the public was Mr. A. G. Butler, who published a paper in the Ann. Mag. Nat. Hist., based upon a collection of moths made by Lord Walsingham in Oregon. He states he does not hesitate to stay that he believes that the different forms do not represent several distinct species, but different forms or varieties of one extremely varaible species.

How then can Mr. Sudder claim that this feeble relic of the tertiaries, stranded, as he tells us, on the loftiest peaks at east and west at the close of the glacial period, unchanged in all respects since that, its imago showing itself but onec in two years, the individual living at most but a few days, always in tribulation and peril, saved only from extinction by its acquired habits of dropping into a crevice, or of clinging to the rocks by the feet, its wings of sacrcely any use whatever, but a constant source of danger—that this miserable creature stands at the head of its genus, its sub-family, its family, of the American fauna, and in fact of the world, the ideal butterfly!*

The study of representative species of butterflies and moths shows us that very different grades of resemblance exist between allied forms inhabiting Europe and North America. I have shown that the modification shows itself sometimes mainly in the larval state; again the perfect insects depart more or less strongly. I have also ventured to decide that these representative species are entitled to specific rank in our nomenclature. They fulfil the conditions of species, since they do not intergrade, and they can be distinguished quite surely by competent specialists.

Just about the time the lilac bushes open their fragrant blossoms the grand insect shown at figure 9 may be seen either hovering over gardens and sipping the nectar of flowers, or sailing majestically down some woodland glade. It generally appears at Ottawa about the first of June, and may be seen for a month or more. Farther to the north it comes later, not appearing at Nepigon, north of Lake Superior, until the end of June. This insect has many characters which make it of interest to the collector.

The lapse of time and further observation on some of the things treated of in papers previously published in the Entomologist, render it desirable to make some corrections and additions.

Trogoderma ornata, Vol. XV., 91, and XVI., 37.— The treatment of this pest there detailed so completely annihilated it that it has not been seen since.

Ameria Texana, nov. sp.

Expanse .80 inch. Of the size of shape of A. Unicolor; the hind wings more rounded at anal angle, in that respect more like Euphanessa Mendica; body slender, antennæ pectinate; palpi slender, short, projecting beyond the front less that in A. Unicolor. Color uniform gray drab, the wings diaphanous, antennæ concolorus except the inside of pectinations at base where they are black, sides of head, back of eyes and a little at base of fore wings and abdoment slightly ochraceous.

This list is presented as a slight contribution to our knowledge of the geographical distribution of the North American Hemiptera. As our literature of this order is by no means overburdened with faunal lists, I trust that the present will find sufficient excuse for its appearance in the mater it contains. I have made every effort to have the list as accurate and complete as possible, under the circumstances. The material was accumulated during brief collecting tour in the Muskoka Lake District of Canada, in the interval from July 25th of August 3rd, 1888.

Egg.—Sub-ovid, boradest on lower third, the base flattened; covered with a very slight rhomboidal network over the upper third, with low knobs at the angles; on the middle the network is still more slight, but the knobs are distinct, and on the lower third the knobs are minute and unconnected by lines; summit flattened, concave; the micropyle in centre of very fine network without knobs; colour bone-white. Duration of this stage about 20 days.

Egg.—Fusiform, thick in the middle tapering to a small rounded summit, the base small, flat; ribbed longitudinally after the manner for the genus; colour yellow-green. Duration of this stage four to five days.

Young Larva.— Length at 24 hours from egg, .06 inch; cylindrical, even; colour brown-green; thickly covered with black points, from each of which a short fine hair; head rounded, blackish-brown. Duration of this stage five days.

We have seen in several of my previos papers that the Owlet Moths, or Noctuidœ of temperate North America, the United States and Canada, resemble most strongly those of Europe. The divergence lies chiefly in the greater number of species belonging to the Noctudiœ fasciatœ, or Catocalinœ; and this is a tropical feature, such forms becoming more plentiufl as we go southward, although Catacala, the typical genus of the group, does not seem to cross the equator, to which latter fact I have already called attention.

Pyrameis Cardui— Usually common; some years quite rare.

Junonia cœnia.— Quite local; never very common. Mr. Scudder, on page 501, speaks of its “rapid, strong and enduring flight.” This would seem to indicate that the habits of this insect in the New England States differ materially from those in this locality or further south. It is rare that this butterfly is here observed over a foot from the ground, and then its flight is most erractic, and usually consists of a new fluttering strokes of the wing followed by an idel sail. This is also the manner of flight from Virginia to Florida, according to the observtions of E. M. Aaron.

Somewhat to my surprise I found this species not uncommon here during the collection season of 1887. Although my entomological interest lies in another direction, and I have, consequently, made no special effort to obtain Lepidoptera, I find Ihave ten specimens of this striking Colas in my collection, all of which I have taken during the summer and fall of 1887. On looking over the collection I discover that these specimens were taken at three different times.

Our President has asked me what methods I adopted for the raising of C. jutta from the egg. I will endeavour of describe them.

As it is well known the larvæ of the genus Chionobas feed on grasses, my first care was to determine what grasses were to be found in the haunts of Jutta, and to notice the circumstances under which they grew. I found several, all rooted in the sphagnum of the swamp. I took home roots of ever kind, and potted them in sphagnum, being careful to close the hole in the bottom of each flower pot with a cork, and to soak the plants throughly with rain water.

Since the food plant and early stages of Graptaj-Album appear to be unknown, perhaps the following notes (incompletee as they are owing to my ignorance of the species larvæ I was rearing) may still be of some value of shed a little light on the early stages of this fine butterfly.

Appreciating the value to students in geographical distribution of faunal lists of a given region, with notes thereon, on the interest that such lists have for beginners in the same field in after years, we have concluded to publish here a list of the Diurnal Lepidoptera known to us to have been taken in the vicinity of Philadelphia. A circle drawn around the new City Hall, with a radius of ten miles, is the line of limit to the “vicinity” here treated of.

The following is a list of the entomological works of Dr. C. Zimmermann:-

1. Monographie der Carabiden, Erstes Stueck, Berlin and Halle, 1831, 8vo., pp. 8 and 76, contains the family Zabroides, five genera, with twenty-six species; review in Oken Isis, 1832, vol v., p. 539, vol. x, p. 1117; extraced in Silbermann Revue, 1833, T.I., p., 45–47. The author's copy belongs to the library of the museum.

By frequent trips to the woods and marshes in spirng, to gather and sift the moss for hibernating coleopterta, by minutely examining the debris on the shore of Lake Erie, and by the use of umbrella and sweeping net later in the reason, I have added to my collection of beetles, since 1886, several hundred good species, The following list contains those of my captures that do not appear in the lists of Candadian Coleoptera.
