I use the name Gortyna in preference to Hydrœcia as, without pretending to be an authority upon the question, it appears to me that there is better authority for the former, as used by Mr. Grote, than for the latter. My acquaintance with the moths of this genus, which I have always admired, dates back about thirty years, but in spite of that length of time my knowledge of them up till last year was of the most meagre description, and apart from the species which has stood so long in our collections under the name Nictitans, and a few specimens of Velata, Walk., I only possessed about half a dozen specimens, mostly in poor condition, representing Immanis, Stramentosa, Rigida, Nebris, Rutila, and a form which Mr. Bird believes to be new.

Habitat: Bogata district, Colombia. Expanse: 1.50 inches.

Head, palpi, thorax and abdomen above, dark mouse colour; beneath, nearly white. Between the eyes are three white dots. Antennæ black. Legs grayish white.

Upper side of fore wing dark mouse colour. There is a broad prominent yellowish-white band extending from costa down to submedian nervure, its inner edge straight, the outer edge swelling outwards somewhat. The interspaces between this distinctive band and the hind margin, also the interspaces upwards towards costa, are heavily dusted with light monse-coloured scales. The nervures and nervules are nearly black. The hind margin bears a slight hairy fringe and a very slight darkish thread.

On the 22nd June, 1901, I received from Mr. A. Kwiat, of Chicago, a batch of eggs of Arctia virguncula, Kirby. These eggs were laid on the 18th June and hatched on the 25th and 26th. The following notes on the early stages of the species were taken. A brief description of the mature larva was published by Mr. Coquillett, in the first number of Papilio, in 1881.

Hagen, in his “Stray Notes on Myrmeleonidæ,” published in the Canadian Entomolgist for 1887 (Vol. XIX., p. 210), called attention to the fact that there are several species of ant-lion-flies in this country which lack tibial spurs. He placed these species in Maracanda, McLach., a genus based on one species from Turkestan. McLachlan's description of the genus agrees moderately well with our forms, except in a few minor particulars. But on examining the figure of the Turkestan insect it is at once apparent that our forms are not congeneric with it. The figure [Fedtschenko's Reise in Turkestan, Neuroptera, Plate 1, fig. 1] shows that in Maracanda there are five or six crossveins before the origin of the radial sector, and that the first branch of the radial sector arises far beyond the end of anal vein. These characters place the genus in a different section from the species we have included in Maracanda.

During the last week of my holidays at Biddeford, Maine, this summer, Colias philodice was abundant and in fine condition, and a great many were taken, in the hope that among them there might be some C. interior, but none of this species were found.

About ten years ago, in sifting swamp mosses for Coleoptera, I met with certain active little insects which, despite their wingless form and almost microscopic size, were recognized as members of the order Hymenoptera. Some of the individuals so captured were afterwards described by Ashmead, in his Monograph of North American Proctotrypidæ, as Bœus minutus and B. piceus. Subsequently, B. americanus, Howard, and B. niger, Ashmead, were also discovered at Ottawa. My solitary example of the former species was found sluggishly crawling on the under surface of a stone in the chilly temperature of early spring, and one example of B. niger was taken with a sweeping-net at the end of September. With these two exceptions, all my specimens of the genus were taken from moss collected at the beginning of winter. All were females, as might be expected, for it is the females oniy of bees and wasps, and probably of all hymenoptera hibernating in the imago condition, that survive the winter in these northern lands.

Eulecanium Fitchi, Sign. This seems to be a very serious pest. The specimens sent by Dr. Fletcher came from Mr. J. D. Evans, of Trenton, Ont., and the scales were infesting a plot of six acres of blackberry bushes, just as they were about ready for the market. Fortunately, however, of the first lot received, over one half of the scales were destroyed by a fungus, and of the second lot, about one third at least. Trenton is a new locality for this scale. In addition, the scale insects were infested to a remarkable extent by two species of Hyperaspis and two species oi Chalcid parasites.

Form and size abour as in D. Citri; pink, distinctly segmented, with a slight covering of mealy powder; caudal tassels short but well-developed; lateral fringe of tassels very short, irregular, but plainly visible in fresh specimens. Females full of young show no signs of producing ovisacs.

The generic title Burtia was proposed by me in the first part of the Notes on the Zygænidæ of Cuba, read February 12, 1866, before the Ent. Soc. Phil., and published in July of the same year. The genus is, however, incorrectly dated “1867” by Kirby in his catalogue of 1892, where B. rubella seems also wrongly given as a synonym of Gundlachia cruenta, H.-S., the two species being presumably distinct. Now, Moeschler had previously, in 1890 (Lep. Porto Rico, p. 349), given “Horamia plumosa, H.-S.,” as a synonym of B. rubella, and “G. cruenta” as a synonym of Callicarus pennipes, thus according to my paper priority over Herrich-Schaeffer's in the Correspoudenz Blatt, although these reversed references may chiefly show that Moeschler could not make out H.-S. descriptions, which are usually scanty.

Brachycistis gaudii, n. sp.—♀. Length about 6½ mm.; shining black, brown on prothorax, at bases of wings, and at extreme (usually covered) bases of abdominal segments; antennæ long, dull reddishbrown, first joint of flagellum equal to second; head broader than thorax; eyes very prominent; ocelli in an equilateral triangle, the area between them elevated; edge of clypeus, and mandibles, dark ferruginous, the latter tridentate; mesothorax shining, hairs and punctures very sparse; metathorax minutely transversely lineolate; tegulæ light ferruginous; wings hyaline, iridescent, nervures pale except the costal, stigma large, dark brown; three submarginal cells and two recurrent nervures, the second recurrent sometimes failing below; marginal cell extremely short, broader than long, its greatest diameter about half length of stigma; first submarginal large, extending along stigma to marginal; second submarginal minute, triangular, entirely cut off from marginal; third submarginal minute, long and narrow, its tip reaching marginal; first recurrent nervure joining first transverso-cubital, second joining third submarginal cell near its base; abdomen shining, very sparsely punctured, with long sparse yellowish hairs; first segment swollen, about twice as long as broad, with a deep constriction between it and the second; apical curved spine long, ferruginous; legs black, knees, apices of tibiæ and tarsi light brown.
