licorne, Zett. (Kroyer, Naturh. Tidsskr. N. R. 41; Ofvers’ K. Yet. Akad.Forhandl. 1844, p. 37.)

Also (ibid. 109) two new species from Lapland , Hydrophorm alpinm andMedeterus paradoxus. The latter with Dolich. scambus, curvipes, femoralis,pumilio, picticornis, &c., according to the author, seems to form a peculiargenus, for which it will be best to reserve the name Medeterus, retainingHydrophorm for H. regius, bipunctatus, litoreus, &o. The species with thefeeler-awn nearly terminal, and the end of the abdomen largely inflected ing [ rostratus, jaculus, truncwum, &c.], demand necessarily the formation ofa separate genus, which may be aptly designated Orthobates, from the mannerof walking as on tiptoe.

[But Hydrophorus has been previously appropriated by Macquart (Ins.Dipt. Nord. d. Fr.) to designate this last group, the synonym Medeterusbeing restricted to the second; while the subgenus Camptosceles has beenproposed for the first section. (Zool. Joum. 1831, vol. v.) The trivialname alpinus has been employed already for a species of Medeterus. (Hal.Ent. Mag. i, 163).]

Bombyliarii. —Loew. (Entom. Zeit.) has added four new genera to thisfamily. Platypygus (p. 127, pi. 2, f. 6, 8) has the body slightly hairy, thethorax gibbous, the abdomen broad and flat, the wings with a discoidal cellemitting three veins, and one submarginal cell; it resembles Usia in itsaspect and movements, but differs notably from the rest of this family inthe veining of the wings. PI. chrysanthemi, new species, from Rhodesand the Greek Islands, found in the spring months upon Chrysan­ themum , greedily devouring the pollen of the flower.— Eclimus (p. 154,pi. 2, v, f. 9-11) comes near to Systropus by its slender Dioctria-like figure, but differs in the form of the abdomen, which is not club-shaped but cylindrical, and in the structure of the face and palps, aswell as in the veining of the wings, from the discoidal cell of which threeveins spring, forming one posterior cell more than in that genus. E. per-spicillaris, new species, found in Asia Minor and the Greek Islands, uponlow plants, on the pollen of which it feeds, and E. gracilis, new species,from the southern coast of Asia Minor.— Chalcochiton (p. 157, pi. 1, f- 14-17), in habit like a Mulio, but distinguished from it, as a genus, by theshort proboscis ending in a knob, and by the possession of pulvilli (frogs).Ch. speciosus, from the southern coast of Asia Minor.— Oligodranes (p. 100,pi. 2, f. 13-16) agrees with Phthiria in the double style at the end of thefeelers, with Geron in the veining of the wings, while it is distinguishedfrom either by the broader and rounder thorax, the straight proboscis thickat the root, and the length and peculiar form of the palps. O. obscuripennisand fumipennis, both new species, found in Asia Minor and in Greece , in thespring months, hovering about the haulm of grass in the warm morning
