 Forhaudl. 1844, p. 37.) 



Also (ibid. 109) two new species from Lapland, Hi/dropliorus alpinus and 

 Medeterus paradoxus. The latter with Dolich. scambus, curvipes, femoralis, 

 pumilio, picticornis, &c., according to the author, seems to form a peculiar 

 genus, for which it will be best to reserve the name Medeterus, retaining 

 HydropJiorus for H. reyius, liputidaiits, litoreus, &c. The species with the 

 feeler-awn nearly terminal, and the end of the abdomen largely inflected in 

 \_rostratus, jaculus, truncorum, &c.], demand necessarily the formation of 

 a separate genus, which may be aptly designated Orthobates, from the manner 

 of walking as on tiptoe. 



[But Hydrophorus has been previously appropriated by Macquart (Ins. 

 Dipt. Nord. d. Er.) to designate this last group, the synonym Medeterus 

 being restricted to the second ; while the subgenus Camptosceles has been 

 proposed for the first section. (Zool. Jouru. 1831, vol. v.) The trivial 

 name alpinus has been employed already for a species of Medeterus. (Hal. 

 Ent. Mag. i, 163).] 



BOMBYLIATUI. Loew. (Entom. Zeit.) has added four new genera to this 

 family. Platypygus (p. 127, pi. 2, f. 6, 8) has the body slightly hairy, the 

 thorax gibbous, the abdomen broad and flat, the wings with a discoidal cell 

 emitting three veins, and one submarginal cell ; it resembles Usia in its 

 aspect and movements, but differs notably from the rest of this family in 

 the veining of the wings. PI. chrysai/thcmi, new species, from Rhodes 

 and 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) conies 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, as 

 well as in the veining of the wings, from the discoidal cell of which three 

 veins spring, forming one posterior cell more than in that genus. E. per- 

 spicillaris, new species, found in Asia Minor and the Greek Islands, upon 

 low plants, on the pollen of which it feeds, and E. gradlis, 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 the 

 short proboscis ending in a knob, and by the possession of pulvilli (frogs). 

 Ch. speciosm, from the southern coast of Asia Minor. Oliffodranes (p. 160, 

 pi. 2, f. 13-16) agrees with Phthiria in the double style at the end of the 

 feelers, with Geron in the veining of the wings, while it is distinguished 

 from either by the broader and rounder thorax, the straight proboscis thick 

 at the root, and the length and peculiar form of the palps. 0. obscuripennis 

 an&fumipennis, both new species, found in Asia Minor and in Greece, in the 

 spring months, hovering about the haulm of grass in the warm morning
