Egg.—Conical, truncated, the top nearly flat, slightly depressed, covered with a fine network of irregular six-sided meshes; these form fourrings about the central rosette, in middle of which in the microplye; the lower part and base rounded and thickly covered with shallow indentations; the sides ribbed, the number of ribs about 34, vertical, slightly sinuous, more so at lower end, narrow with rounded spaes between, which are crossed by many fine lines; color yellow-green. Duration of this stage about 12 days. The egg is like that of Galactinus, but has fewer ribs.

After examining the European Ammoconia caecimacula (in which the ♂ anntennæ are dentate and furnished with pencilled setae or hair; the form stout; the tibiae, of the middle and hind legs only, spinose; the thorax and abdomen with slight dorsal tuftings), I find that my species are not congeneric, and I accordingly refer them to this genus named in memory of a Brooklyn Entomologist, Harvey J. Rich, who died while yet young, and whom I knew “before the war.” The type of Richia is Chortalis and its probable dimorphic form Aratrix, though we do not know quite surely whether the two are so related or not; they occur over the West and Southwest, to Texas.

In 1863, Mr. W. H. Edwards described a male Hesperian from Michigan under the name of Hesperia Pontiac, closely resembling the species figured by Boisduval and LeConte, under the name of Arpa, as well as the larger Florida species Edwards subsequently described under the name of Pilatka. In the same paper in which Pontiac was described and immediately preceding it, he described, also from Michigan, a female under the name of Hesperia conspicua.

Young Larva.—Length .10 inch; body cylidrical; head broader than the body, oblique. Color of the upper part and sides of joints 2,4,5,7,8,9,12 and 13, reddish purple; the rest of the upper part and sides and the venter dull whitish; six rows of tubercles from which proceed small clusters of brown hairs, the four rows of dorsal clusters longer than the body; head black; feet purplish. Duration of this period, 4 days.

1. Dryopteris rosea Walk.

The full grown larvæ, in the beginning of July, feeding on Vibrunum acerifolium, the “Maple-leafed Arrow-wood,”* are, in their last stage, olivaceous brown, pale dorsally; dorsal line single, dark; a triangular dark patch on each side of the body commencing on segment 4 (I do not count the head) and bordered above the abdominal feet with pinkish; anal segment prolonged.

Whether they fill the listener with a train of happy thoughts, as Gilbert White says, or whether they produce a sadness because the days of summer are nearly gone, as Dr. Harris asserts, the songs of crickets and other Orthoptera have, nevertheless, the merit of always being interesting. An insect that can sing—that has something to say—even though it be the same, night after night, enjoys a sort of individuality, and this lon discussion of the Katydids and the quiet murmur of the tree crickets, constitute one of the chief charms of our summer evenings.

During the past summer I collected at Dublin, Wayne Co., Ind., a number of Œdipodini that seem to be a long-winged variety of the above named species. A comparison of the dimensions given by Thomas and Saussure for D. carolina and D. longipennis with measurements taken from eleven of these specimens, will show what the difference amounts to.

On page 38 of the February number of last year's Entomologist, is a note, written by myself, concerning an injurious Saw-fly larva which had appeared in abundance in the neighborhood of Quebec. I preserved quite a number of the cocoons of the species, hoping to obtain the perfect insect from them. Some of the cocoons were kept in a box in my study, others in a tin case placed in the cellar, and yet others in a glass jar half filled with moist earth.

Having newly arranged the Coccidæ of our collection, which have been named by Prof. J.H. Comstock, I compared them with the professor's Catalogue for 1883, and ascertained the presence of two-thrids of the 168 numbers enumerated. I find that only 27 N. Amer. species are wanting. Among the insects received in the collection of the Peabody Academy is Lecanium tiliœ, A. Fitch, from Mt. Carroll, Ill., by Mr. Shimer, very probably identical with A. Fitch's species, and Lecanium tulipiferœ, Cook, by typical specimens.
