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).

Allied to F. denudata, but differing greatly in important particulars, Fore wings are bright shining seal-brown, deep orange along the costa for the basal half. At the middle of the wing at base in a narrow denuded space, and the internal angle is also devoid of scales, but much more narrowly so than in denudata. The transparent space is golden yellow in shade. Lower wings transparent golden yellow, with very bright but dark opalescent reflection. The margin and spot at the extremity of cell dark brown. Antennæ bluish black, orange brown at the base. Head, disk of thorax, and the upper portion of the abdominal segements, black. Eyes black, palpi with black at their base. Front of head, collar, sides and base of thorax, posterior edges of abdominal segments bright orange. Feet and legs wholly orange without any black bands.

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.

Sergiolus bicolor, n. sp.Length, ♀, 8 mm. Cephalothorax and legs pale reddish-yellow, mandibles and sternum scarcely darker, basal half of abdomen pale gray, apical half and spinnerets jet black, the line separating the two slightly convex in front; venter pale gray except the apical two-fifths, which is black, but broadly indented by the gray in the middle. Cephalothorax rather slender, about one and three-fourths as long as broad, plainly longer than patella plus tibia IV., not much narrowed in front, no trace of a dorsal groove. Posterior eye-row plainly recurved, the P. M. E. round, about twice their diameter apart, and about as far from the scarcely larger P. S. E. Anterior eye-row much shorter than posterior, nearly straight, the A. M. E. slightly smaller than P. M. E., more than their diameter apart, and rather nearer to the slightly larger A. S. E., several stiff black bristles in eye-region.

Most northeastern North American Spiranthes are adapted to pollination by long-tongued bees (e.g., Bombus spp. and Megachilidae). The salient features of this adaptation are (i) a long, flat viscidium which attaches the pollinia readily to the flat rigid galea of the insect's proboscis, (ii) the nectar secreted into the base of the floral tube, (iii) the flowers are protandrous and sequential beginning at the base. In contrast, Spiranthes lucida apparently is pollinated largely by halictine bees. It differs from other northeastern taxa of Spiranthes in (i) having an oval viscidium which attaches the pollinia to the clypeus below the antennae, (ii) having the nectar available on the under side of the column behind the stigmatic surface, and (iii) in lacking protandry. In the characteristically Bombus-pollinated taxa, protandry is accomplished by a change in the position of the terminal portion of the column with respect to the lip, apparently due to cell elongation in both the column and the lip. The present investigation documents protandry in S. cernua var. cernua, S. lacera var. lacera, S. lacera var. gracilis, S. laciniata, S. magnicamporum, S. ochroleuca, S. romanzoffiana, S. tuberosa, and S. vernalis. Bees moving up the spike from the older female flowers to the younger male flowers act initially as pollen donors and later as pollen receivers; thus cross-fertilization is enhanced. Halictines occasionally act as pollinators of characteristically Bombus-pollinated taxa by visiting the flowers upside down so that the pollinia are inconspicuously attached to the lower side of the prementum. Data presently available for northeastern North American Spiranthes fail to establish pollinator specificity as significant in speciation except perhaps with respect to the separation of S. lucida from the other 14 northeastern taxa.

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.

Teras comandrana, n sp.Expanse of wings 13 mm. Head, palpi thorax, and basal half of forewings, light yellowish-brown or fawn coloured. A large cinnamonbrown tringular spot rests on the costa, extending from the middle to the outer fourth, and the apex extends nearly half way across the wing. The outer part of the wing is light cinnamon-brown, and the whole surface is crossed by numerous oblique, irregular metallic band, which are visible only in an oblique light. A row of minute black tufts alon ghe inner side of the costal spot, two or three more near the fold below, one on each side of the fold at the basal third of the wing, and three near the middle of the wing at the outer fourth. Fringe concolorous with the outer part of the wing.
