For many years past, those most interesting of Hymenopterous insects—the Horntails and Sawflies — have received the closest study by some of the ablest Hymenopterists of the world. Cresson and Norton, in America; Newman, Westwood, Kirby, and Cameron, in England; Klug, Hartig, and Konow, in Germany; Lepeletier and Andrè, in France; and Thompson, in Sweden, have all contributed much to our knowledge of these insects, and made decided improvements in their classification.

Podalirius phenax, n. sp.—♂. Length about 9 mm.; appearance of P. maculifrons (cress.), with the same white pubescence (mixed with black on hind part of mesothorax and front part of scutellum), the same clear wings (but the second submarginal cell is less narrowed above), and the same legs, except that the tarsi are wholly dark. The black antennæ are considerably longer, when the head is thrown back they reach to postscutellum; scape with a broad white stripe; first joint of flagellum a little shorter than third. Eyes a beautiful dark lavender or gray-blue, instead of green. Clypeus (except the narrow black anterior edge) a transverse supraclypeal band, lateral face-marks (triangular, with the upper side deeply excavated), labrum (except the usual pair of spots), and large patch on mandibles, pure white, shining, like porcelain. Abdominal bands more or less interrupted in the middle; first segment without a band; apex with two spines.

XXIX. The Œdemeridae and Cephaloidae of Ontario and Quebec.

The family Œdemeridæ is of small extent, only five species, representing four genra, being recorded from the region under discussion. None of our species are very samll and two of them at least often reach a size sufficient to render them readily noticeable. With the exception of Nacerdes melanura, which frequents houses, wharves, lumber piles and shipping, they are to be found on bushes and trees or else under boards in wooded districts.

I have been so fortunate as to have, while making the following notes, the collection of Philanthus belonging to the Academy of Natural Sciences before me.

Philanthus Sanborni, Cress. (Philanthus Trumani, Dun. Ent. News, VIII.,70, ♂, not ♀.)

This species does not always have the W-shaped mark on face described by Cresson.

The Epiplemidæ are a family of moths fairly well represented in India. (see Hahpson's Moths of India, III., 121.) Only one larva is known, that of Epiplema latifasciata, Moore, and unfortunately the figure is insufficient to show more than that the feet are normal five abdominal pairs, and the setæ probably single. The family occurs also sparingly in America. Hulst lits three genera as a subfamily of Geometridæ the Strophidiinæ (Trans. Am. Ent. Soc. XXIII., 309); but I would certainly prefer Hampson's treatment, both as to the name and rank of the group.

Leptomeris nigrodiscalis, n. sp.

Expands 24 mm. Palpi and front black; vertex ochre-white; antennæ whitish below, blackish or smoky above; thorax and abdomen white, slightly ochre stained. Fore wings white, with four somewhat indistinct, broad, even, wavy, ochre lines, the first well out from base, the second just outside of discal spot, the third in outer space, the fourth marginal; hind wings with corresponding broad lines; discal points prominent, rather large, jet black; four fine marginal black points below apex on fore wings; beneath more diffuse, more fuscous, less ochreous, the lines less determinate; discal spots not so marked, black points as above on margins of fore wings, and some appearing below apex along margin on hind wings.
