Œdipoda obliterata, nov. sp.

Male and female. Length to tip of elytra 1.50, to tip of abdomen 1.10 to 1.30. Pale reddish-brown or dull yellowish tinged with rufous, with irregular transverse bands of dark fuscous spots.

Occiput not prominent. Vertex broad, moderately deflexed, margins with sharp carinæ forming a distinct sub-quadrate, median foveola, which is divided into two equal sections by a distinct longitudinal, median carina that extends back part way upon the occiput; sides of the foveola parallel between the eyes, and bending abruptly inward toward the fastigium in front, continuous with the sides of the frontal costa; fastigium with a double indentation.

Pamphila Byssus.

Male.—Expands 1.6 inch.

Upper side dark glossy brown ; the basal half of costa of primaries ferruginous, as well as a little of cell below adjoining; at the end of cell an irregular yellow-fulvous bar within ; across disk a bent yellow-fulvous band, starting on costal margin about three-fifths the distance from base to apex, bending round cell and continued to middle of submedian nervure, narrow at top, but below cell widening rapidly; the basal half of inner margin washed fulvous.

In the proceedings of the Zoological Society of London, Feb. 17th, 1880, is an interesting contribution to the Tineidæ chiefly of this country, by Lord Walsingham, entitled “On Some New and Little Known Species of Tineidæ.” The author states, from a comparison of specimens and figures of Adela schlœeri Zell. (which I had previously recognized as Adela (Dicte) coruscifasciella Cham.), that it is identical with A. Ridingsella Clem., preserved in the collection of the Entomological Society of Philadelphia; a fact which I should not have suspected from Dr. Clemens' description of A. Ridingsella.

In my Report on Silk-producing Bombyces and other Lepidoptera, reprinted from the “Journal of the Society of Arts,” Feb. 13th and March 5th, 1880, I speak of the disastrous effects of the weather on most species during the year 1879.

This year (1880), although the splendid weather we had in August and at the beginning of Sept. allowed of the successful rearing of several species in the open air, the wet and cold weather lasting till about the end of July affected and retarded Lepidoptera, as in 1879; the moths of Samia promethea, for instance, had not all emerged before the end of August. With a ferv exceptions, none of the Indian species emerged at all, and ova of many well-paired female moths were partly infertile.

Euchaetes collaris. Fitch.

On Jnne 7th, 1879, I obtained some eggs from a ♀ captured the day before. The eggs were smooth, pale green, spherical in shape and inch in diameter. The eggs hatched on the 12th. Larva ⅛ inch long, pale green, largest at middle of the body and tapering slightly towards both ends. Head slightly bilobed, of a faint brownish color, with a dark brown spot on each side.

EGG—Conoidal, depressed at top, flat at base, shaped generally like the eggs of Argynnis ( Idalia, Cybele, &c.), but taller in proportion to its breadth than in the species named, with the sides less rounded ; marked by about 20 prominent, vertical, straight ribs, half of which extend from base to summit, forming around the depression a serrated rim, the rest ending irregularly at two fifths to four fifths the distance from base, the shorter ones occasionally joining the others ; marked horizontally by numerous prominent stræ. Duration of this stage from 5 to 12 days, according to the season.

Ochyria designata, Pack.

Mature larva, five specimens.—Head roundish, flattened, as wide as the first segment, yellowish green ; jaws brown. Body thickest at the 9th segment, attenuated anteriorly; yellowish green, the dorsal and subdorsal spaces reticulated and lined with brown ; a narrow stigmatal brown line and a dorsal row of triangular brown spots, one each on the 4th, 9th and 10th segments, and two on each of the intermediate ones; a minute substigmatal black spot on the anterior part of each segment from the 6th to 9th.

But little is generally known regarding the life history and habits of mites. They have not yet engaged the attention of many naturalists, still their tribes are many, and the hosts of individuais composing them “too numerous to mention.” We purpose to present our readers with a few facts relating to two of the better known species of mites.

I desire to call the attention of Entomologists to a very valuable contribution to Entomological literature recently made by Lord Walsingham. The work is entitled Pterophoridæ of California and Oregon, and is published in an octavo volume very neatly gotten up, and containing sixty-six pages of letter press, fully illustrated by forty-eight colored figures on three plates. Forty-one species are figured, of which three do not belong to the Pacific fauna as far as known, but are given for convenience of comparison. Twenty-seven new species are described.

A few of the members of my zoology class and myself have taken here 821 specimens of Catocalæ in nine consecutive days, collecting from August 16th to August 26th inclusive, omitting Saturday and Sunday, during which no collecting was done. These were all taken in the afternoons, usually from one to four o'clock, by whipping the trees, and all within easy walking distance from the University.

Packardia Goodellii, n. s.

Entirely blackish with a faint brown shading about internal angle, where are two white unequal spots as in geminata. Fringe blackish, concolorous, interlined with pale and with a distinct white fleck or spot below apices ; this distinguishes the moth from any of the genus.
