On the evening of the 31st July, 1899, while collecting moths at the electric light, close to the entrance to the Central Experimental Farm, I was fortunate enough to secure a female of Euprepia Caja, L., var. Americana, Harr. I enclosed her alive in a small box over night, and by the morning she had laid nine eggs. From these eggs five larvæ hatched, and as I have succeeded in bringing two of these through all their stages, my notes may be of interest to some of the readers of the Canadian Entomologist.

Egg.—Semi-ovoid, about .75 mm. in width, at widest part; pale yellowish, smooth, shiny.

The following apparently new species of Anaphorinæ have been received since the paper published in Can. Ent., XXXII., 307, was prepared:

Genus Atopocera, Walsingham.

Wals., Proc. Zool. Soc., London, 1897, p. 169.

Lord Walsingham would probably not have proposed this name if he had been aware of the previous use of the masculine form of the same term (Atopocerus, Kraatz, Deut. ent, Zeit., XXXII., 360, 1888. However, the different endings will probably sufficiently distinguish the two genera.

At the first meeting of the autumn, held on the evening of October 15, sixteen persons present, Mr. Wm. H. Roever, of Washington University, presented an elaborate paper discussing in detail the subject of the establishment of the method of least squares. Professor F. E. Nipher presented two papers, entitled respectively Positive Photography, with special reference to eclipse work, and The Frictional Effects oi Railway Trains upon the Air; and Mr. C. F. Baker exhibited an interesting collection representing nearly all of the species of fleas thus far known, which he had prepared for the United States National Museum.

The species here brought together were most of them collected by Mr. A. P. Morse, in the summer of 1897, and as they belong to miscellaneous genera, none of which require special revision, the descriptions are here collected for publication.

Loboptera americana Scudd.

The single original specimen of this species was taken in Arizona, and was apparently collected in alcohol, as two fresh specimens taken by Mr. Morse at Cahon Pass, Cal., July 18, differ in colour and in the shape of the pronotum, requiring its partial re-description.

Nothing is more aggravating than to be compelled, soon after completing a monographic work, to make changes in the nomenclature and synonymy; yet this is the purpose of this paper concerning the genus Acronycta, which was monographed by Dr. H. G. Dyar and myself in Proc. U. S. Nat. Mus., XXI., pp. 1–194, 1898.

It was explained in the introduction to this paper that, because of its interesting early stages, the late Dr. C. V. Riley had been, for years, accumulating material for a thorough study of Acronycta; therefore I had made no effort to become closely familiar with the species. Some time before, Dr. A. G. Butler, of the British Museum, attracted in the same way by the larval difference, had divided the species among several genera, referred to several families; allowing superficial and secondary characters to mislead him, as be has since admitted. In 1886, while arranging the Grote material, Dr. Butler made comparisons with other types in the Museum, the results of which were published in 1887 in “Entomologica Americana.”

Thamnotettix chiragrica, n. sp.—Form and size of T. parallela nearly, superficially resembling Cicadula punctifrons, var. Americana. Length, 6 mm.; width, very nearly 2 mm.

Vertex twice wider than lone, half longer on middle than against eye, disc convex slightly sloping, rounded to the face, front very broad and short, width at base and length about equal, the disc convex. Pronotum a third longer than the vertex, over twice wider than long; elytra long, almost parallel margined to the apex, venation distinct, apical cells short, their bases truncate, the anteapicals long.

(1) Parasa prasina, Dyar, Psyche VIII., p. 273, 1898 (Central America), is preoccupied by Parasa prasina, Alph., Deut. ent. Zeit., 1895, p. 186 (Western China). The Central American species may be called Parasa wellesca.

Papilio asterias, Fabr. Var. semi-alba, ♂, nov. var.

On July 31st, 1899, I captured a very interesting form which is out of the ordinary run of the variation which prevails in this species. The size and markings are the same as the normal form, but all the maculations on the primaries are pure white, while the markings on the secondaries are of a deep golden yellow. The under side is the same, but not so conspicuous. Two males in my collection.

Myiocnema, new genus.

This new genus falls in a table of the genera of the Aphelininæ next to Encarsia, Forster, the antennæ being 8-jointed and the club in the female being 2-jointed.

The head is transverse thin antero-posteriorly, the occiput concave, the vertex impressed; the thorax has several long bristly hairs, and the parapsidal furrows are distinct but very delicate, almost invisible; the front wings have a large discoidal cloud beneath the marginal vein as in Coccophagus orientalis, Howard, the stigmal vein is distinct, not very short, but still shorter than the marginal vein and a tittle shorter than the post-marginal, the marginal vein being a little longer than half the length of the submarginal vein.
