I. Argynnis Semiramis.

Male.—Expands about 2.3 inches.

Upper side bright fulvous, very little obscured at base; the black markings much as in Adiante, that is, slight on primaries, and still nore so on secondaries, the spots on disk and to base being scarcely more than streaks.

Under side of primaries cinnamon-red at base and along inner margin to median, the upper two median interspaces more or less buff in middle; this red also crosses basal half of cell, and borders median to the arc; the remainder of cell and the discoidal and costal interspaces buff; a brown sub-apical patch, and hind margin brown; the sub-marginal crescents brown, and near apex lost in the ground color, from upper branch of median containing imperfectly silvered spots, the others without silver; the two spots on the patch well silvered.

Having examined a good number of dead trunks of the basswood or American linden, Tilia Americana L., here this fall, I have found quite a list of Coleoptera in them either under the bark or in the decayed wood. The following is the list, which embraces thirty-four species taken from 13th October to 3rd November, 1885. Some of the species are only of accidental occurrence in the trunks, but will be readily known, and are given to record them from this locality. The determinations are mostly by Dr. Horn:—

Tachys flavicauda Gyll. Colonies or scattered individuals mixed with colonies of Silvanus planatus Germ., or by themselves, under the bark of the less decayed trunks.

Within the first year of work in this branch of entomology in the Ottawa district, I was able to make acquaintance with all the 26 orders into which Hymenoptera are divided in Mr. Brodie's Canadian list; and now at the end of our second year, out of 247 genera, only about 70 remain unrepresented, while 13 genera are added not yet before met with in Canada, two of which have never been described.

I shall leave out the Uroceridœ and Tenthredinidae, and not include them in the following figures, as Mr. W. H. Harrington has given especial attention to those two orders, and has already published an article on them.

Brotis vulneraria Hüb.

This moth appears to be the only one of its genus so far known in the United States.

Head small, yellowish red, almost hidden between the large and prominent eyes, which are naked; palpi medium, slender, lighter colored; thorax long, covered with long fine hair; abdomen much shorter than the anal margin and Hesperi-shaped. Posterior wings elongated, costa straight, somewhat curved at apex, outer margin straight, inner margin somewhat rounded. on anterior wings the anal margin is longer than upper and outer margin, the latter being strongly rounded.

Prof. F. W. Putnam communicated to me a larva of Scenopinus found in his house under a carpet. It belongs very probably to Sc. pallipes Say, which was reared by Mr. Sanborn out of larva found under a carpet. The larva is figured by Prof. A. S. packard, Guide, p. 1 and 401, and Proc. Essex Just., October, 1867, p. 94, where three other larvae found under the carpet are mentioned. There are three European species reared. Sc. senilis (Bouché Naturg. Ins., p. 46) is said to live in rotten fungus on willows and other trees. Sc. fenestralis (Assman Stett. Ent. Z. 1863, p. 400) in over-ripe strawberries; but it has been later suggested that it may belong to another species. Frauenfeld (Verh. zool. Bot. Ges. Wien. 1864, vol. xiv) has reared Sc. fenestralis from larvae found in a horse hair mattress. Prof. Loew records the larvae living in a swallow's nest. Mr. Perris (Ann. Soc. Ent. Fr. 1870, vol. x., p. 230) tells that Dr. Cartereau found in a swallow's nest a pupa of Lucilia dispar containing an imago of Sc. fenestralis which had not been able to leave the pupa of Lucilia, so the larva must have fed on it.

Rheumaptera brunneomaculata, sp. nov.

Abdomen and ground color of wings white. Head, thorax and antennæ cinereous. Inner third of fore wings containing three irregular ashcolored lines more heavily shaded towards the thorax. Mesial band crossed by two narrow, irregular and somewhat interrupted cinereous lines, between which on the inner margin of the wing is located a very distinct sub-triangular spot of deep brown color. Another larger, nearly quadrangular, very distinct brown patch, widest on costa, extends from costal margin to near the middle of the wing, in the lower part of which is located the oblong very dark brown discai dot.

As my former notes on the Ant Lions were of interest to some of your readers, perhaps a few additional particulars on the same subject may not be objectionable to them. Having had another opportunity of observing their habits, I made the best use I could of it. The abdomen of the nymph is somewhat heart-shaped, flat beneath and very much rounded above, thickest near the thorax, and sloping off suddenly to the sides and tail, which is an acute point. The thorax is long, and with the head is narrow and flat above, a form no doubt well adapted to its requirements. Its mode of travelling is backwards, always “advancing to the reat,” one side contracted, which produces a circular movement, so that when one was placed in the centre of,the palm of the hand, it made two rounds before it dropped over the side. As soon as it touched the sand it put itself instantly out of sight under the surface, where it lay for a short time perfectly quiet. When it began the formation of its pit, which I watched to its completion, it commenced by a jerk of the head and thorax, which threw the sand off and exposed them to view. It lowered them at once, made a sudden start back, when the sand covered them; then another jerk and another backward move rapidly executed, always throwing the sand to the outside.

If a specimen becomes oily, it is generally believed that its beauty can never again be restored; but with a trifling cost and a little labor, any specimen will in a short time have again its former lustre, without injury to the insect. This remedy has been tried on the most tender Diurnals, as well as on Sphinges and Noctuids; it can be used on every insect. Should a specimen be oily throughout, body and wings, it may be put in the following fluid: One part of sulphuric ether to two parts of the strongest alcohol, and left therein for about 24 hours. Should the specimen be very oily, another bath may have to be applied. Should this second bath, after removing the insect, be only slightly discolored, the insect may be put in the last bath, which consists of pure sulphuric ether, in which it is left a few hours only. After being taken out and partly dried, it is put on the spreading board.
