Aristotelia Youngella, sp. nov.—Head. antennæ, palpi, thorax abdomen and legs shining iridescent green. Basal half of front wing and outer half along costa black or very dark brown, heavily overlaid with iridescent green. The dark basal half is outwardly margined by the black ground colour, owing to absence of the iridescent scales at this point. All the outer half of wing, except the dark costal streak, is dull ochreous, inwardly margined by a pale yellow line, the latter adjoining the dark line of ground colour outlining the basal half.

Eucosma Pergandeana, n. sp.— Expanse of wings, 16–20 mm. Head, palpi except a touch of fuscous on the outside, basal segment of the antennæ, whitel flagellum of antennæ fuscous, annulate with white. Thorax varying from white to pale straw colour.Ground colour of fore wings white or pale cream colour; the outer half of the costa with about eight oblique fuscous lines, which are lost in the fuscous dorsal portion of the wing. The remaining portion of the wing is streaked longitudinally with fuscous, but so diffuse as to render the lines very indistinct, and the surface behind and beyond the cell is nearly unifromly pale grayish fuscous in some specimens; the ocelloid patch near the anal angle is represented by fragments of three fine blackish lines, more or less obliterated and broken by a short vertical bar of more of les distinct metallic pale gray scales; a similar one beyond follows the outer margin and joins the first below, but is broken near the middle of its course.

During his study of the ecology of red pine plantations, Mr. J. L. Martin, Forest Insect Laboratory, Sault Ste. Marie, Ontario, found a species of Laspeyresia feeding as larvae under the bark of living trees. This species is described here to enable him to report on the results of his investigation.Laspeyresia resinosae, new speciesAntenna, head, thorax, and abdomen powdery-grey. Basal half of forewing grey; outer half blackish, with cupreous reflections, the tips of the scales ochreous; outer three-fifths of costa with four pairs of silvery-white geminations; the basal pair of geminations fuse into a single, angular, transverse, shiny-leaden fascia, that extends to the trailing margin just beyond the middle; a similar fascia arises from the second costal geminations, and extends only to the fold; a third leaden fascia arises from the apical geminations, extends irregularly to the tornus, and is broken into three almost equal sections; the central portions of the second and third fasciae are narrowly margined with a few black scales, representing a very poorly defined ocelloid patch; outer margin with a very distinct black line basad to the shiny leaden fringe; the black line cut by three white dashes, two opposite the breaks in the outer, transverse fascia, and the third at the tornal end of that fascia. Hind wing powdery-grey; fringe dirty-white with darker basal line. Under-surface and legs silvery-grey. Tarsi black banded. Wingspread: 9.5-10.5 mm. Moth in late June and early July.

Yellow Stripe

Length 1.20 inches; cylindrical, rather slender, two warty elevations on the dorsum of joints 5 and 12, elsewhere the piliferous spots scarcely perceptible, except for the single hair that arises from each. Color green; a dorsal pale yellow line, bordered on each side on joints 3 and 4 by a purple line; outside this a pale yellow stripe that diverges on joint 2, gradually diverging again on joints 4, 5 and 6, where it reaches below the usual region of the subdorsal line, extending from this back to joint 11, from which it gradually converges to the elevations on joint 12, touching these on the outside, the diverging and converging referring to the stripes on both sides of the body. These stripes send more or less prominent deflections down the sides of joints 7 and 10. In some examples the space between these stripes and the dorsal line contains a pale whitish stripe each side of the dorsal; the deflections, and a little on joint 5 and the elevations, are reddish purple.

A New Species

This paper includes descriptions of a new species of Iziphya Nevsky and one of Euschizaphis Hille Ris Lambers. The former genus is well represented in North America, but Euschizaphis, which is best known for its association with the Juncaginaceae, has not been previously recorded from the western hemisphere.Iziphya punctatella, new speciesApterous Viviparous Female.–Colour when alive: Ground colour of head and body yellow with black spots around the bases of most of the setae (Fig. 4). Antennae dark except for the basal half of segment III which is yellow; apex of rostrum dark; legs black except apical two-thirds of tibiae which are colourless. Colour when macerated: Essentially as when alive, but yellow areas colourless or nearly so.

New Form

Prionia levis, n. var. or sp.Primaries without the delicate frosted or silvery appearance, and without the numerous short, fine, strigate, brown lines of bilineata. The brown scales are present, but are uniformly and evenly distributed, save where they form the two brown lines which cross the wing, and a little darker shading near the outer edge and apex. These two transverse lines are about a third wider apart that in bilineata, the second narrowly edged externally with the clear, pale yellow ground-colour of the wing.

Pyrgota Chagnoni, n. sp.♂.—Head reddish, vertex reticulated with brown, cheeks and occiput yellowish, antennal foveæ brown; antennæ yellow, thorax and scutellum red; numerous fine brown specks are so arranged as to form two obsolete dorsal lines and two spots on each side divided by the suture; this character is especially noticeable when looking from the head toward the scutellum, and gives the disc of the thorax a rugose appearance. Abdomen narrow, brownish, shining, posterior margins of the second, third, fourth and sides of the fifth segment more or less blackish. Halteres yellow. Legs variable in colour, with thick black hairs, especially on tibiæ, anterior and middle coxæ, basal half of all the femora and tibiæ, and all except the terminal joint of the tarsi yellow; posterior coxæ and the terminal portion of the femora reddish; outer half of all the tibiæ and the terminal joint of the tarsi blackish; the outer portion of the posterior tibiæ is intensely black, while the black of the anterior tibiæ is due largely to long thick hairs. The wings can best be described by reversing that of P. valida, Harris, given by Loew (Monog., Pt. III., p. 75).

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.
