Lygus Chagnoni, n. sp.— This species of the genus Lygus is of a form near to L. pabulinus, Linn., in appearance.

It is ovate, convex bright green in living specimens, with irregular purplish-brown markings at the base of the membrane, smooth and without bristles, and a silky pubesecence on the sides of the pronotum, which has an orange-yellow border next the head, shading backwards in narrow lines into the green coloration, so as to make the reen appear in broad bands.

I have spent more time than I like to think about identifying bees of the genus Megachile, so I have no apology to make for offering somenotes which will, I hope, make the process easier for others:

Megachile frugalis, Cresson.— This species was described from the male. I have before me a female collected by Dr. Davidson at Lancester, California. It practically agrees with the description of M. zaptlana, Cresson, ♀, except that it has no lines of white pubescence on the thorax. M. occidentalis, Fox, ♀, is very similar, and has the lines of white pubescence, but it has a different clypeal margin, and the very scanty hair on the disc of the clypeus is white. In M. frugalis, ♀, the clypeus has long black hair; the ventral scopa is creamy white, black on the last segment. These bees are all of the elongate narrow type. The anterior margin of the clypeus in frugalis, ♀, can hardly be called excavated, but presents three gently-rounded prominences, the margin between them being slightly concave.

Dryophanta rydbergiana, n. sp.—Gall: on leaf of Quercus rydbergiana, Ckll. (Torreya, Jan., 1903). solitary, 6 mm. diameter, spherical, faintly shiny, light ferruginous, with a microscopically tessellate surface and a scattered stellate pubescence; base concave, point of attachment small; contains a single large cell; the space between the cell and the exterior filled with spongy tissue, which is light green within and ferruginous outwardly.

In the July number of the Canadian Entomologist, Prof. J.M. Aldrich attempted to rescue Dr. Williston's Culex inornatus, from the synonymy by referring the true Culex eonsobrinus, Desvoidy, as a synonym of Culex pipiens, Linné, and denying that any of the other species which the writer originally placed in the synonymy of consobrinus is identical with inornatus.

The erratic migrations of certain insects, often in countless swarms, have been noticed and put on record by many observers. In a country where, perhaps, they are scarce, or, it may be, almost wanting ordinarily, they may suddenly put in an appearance in such numbers as to defy all attempts at computation; or immense swarms of them may sometimes be seen far out at sea, flying steadily in a direction which may take them out so far as to effectually prevent any return.

Bombus Cooleyi, n. sp.— ♀. Length, 16–17 mm. Integument black; clothing black, yellowish white, pale ochreous yellow and rusty yellow. Head, seen from in front, about as wide as long. Malar space abont one-sixth the length of eye. Third segment of antenna one-half longer than fourth, and scarcely longer than fifth. Face thickly clothed with pale yellowish-white hair, on the sides mixed with black. Vertex clothed with yellowish-white hair, which is fringed in front with black. Cheeks clothed with brownish-black, sometimes slightly mixed with whitish, hair. Clypeus shining, sparsely punctured, labrum fringed on free edge with rusty yellorv hair. Clothing of thorax above and on sides yellowish white, mixed with black in front of insertion of wings. A broad patch of black berween the wings surrounds the smooth, polished mesothoracic disc and extends back in a point over the middle of metathorax. On each side of metathorax is a tuft of yellowish white bair.

Phlepsius collitus, n. sp.— Resembling fulvidorsum, but smaller and paler. Colour fulvous, elytra brown, with two imperfect light bands. Length,♀, 6 mm.; width 2 mm. Vertex short, obtusely rounded, but little longer on middle than against eye, three times wider than long; disc convex; the anterior margin distinct, but not sharply angled; elytra rather long and narrow; venation distinct, claval veins separate, parallel. Colour: vertex fulvous, sometimes with faint brownish mottling; face unifrom dull brown; pronotum fulvos, usually mottled with brown on the disc; scutellum fulvous.

Xiphydria erythrogaster, sp. nov.— ♀. Length, 9.8 mm. Head and thorax black, marked with yellow as follows: The black of the head is confined to the occiput, a large spot on the crown is dilated on each side, but does not quite reach the eye, while the yellow is confined to the cheeks, the face to above the insertion of the antennæ, the front orbits and a V-shaped mark above the eyes. Mandibles yellow, with black teeth; prothorax yellow, with a black line on collar above and a black mark in the lateral depressions; mesonotum black, with two yellow spots on the disc; scutellum with the axillæ yellow; meso- and meta-sternum yellow, with black marks.

I have taken, in the Province of Quebec, the undermentioned species of two-winged flies, the names of which do not appear in the Toronto Check List

Little is known regarding the sounds produced by the Rhynchota, and that little refers almost exclusively to the Cryptocerata, of which Corixa has had the most attention; and some few observations have been made on Nepa, Sigara and Notonecta. It seems to me, therefore, that it would be well to put on record the observations and notes made by me on the stridulation of Ranatra, together with a few other remarks on this insect.

In Dr. Dyar's recent very full and careful List of North American Noctuids, Wash. Cat., pp. 98–247, are a few errors which I would briefly point out in this journal. They have mostly arisen from a neglect of a couple of papers in Can. Ent., and one in Proc. Am. Phil. Soc., 1895, as well as from a two literal following of Prof. Smith's Washington list. With regard to the general sequence of the order adopted, I have given that preferred by myself in these pages, and can only repeat here that the Noctuid series (Lithosia—Noctua) affords a parallel to that of the blues and skippers in the butterflies, and that I should place them below the series Bombyx, Lachneis—Geometra, disturbing as little as possible the older classifications.
