characters of several new genera of the Cecidomyini and Lestremini, anextract from which is given in the Isis. The third, containing a distributionof the European Diptera into 35 families, is in theAnnali di Bologna (vol.vi),and an extract is given in the Isis (18411, p. 614.) There is, besides, afourth article upon the genus Phasia, and a fifth upon Chortophila, [withanother on a new genus of Svrphnhe.] I have not been able here to get asight of these Transactions as yet.

TipularijE. —Loew has proposed several new genera. Prionocera (Ent.Zeit. 170, pi. 2. f. 30, 31), intermediate between Ctenophora and Tipula, thewings and feelers as in the latter, the feelers serrated beneath, withoutwhorls of hairs, no frogs (pulvilli) to the feet, the body clothed with softalmost woolly down. A new species from the neighbourhood of Posen, Pr.pubescem, rather more than 3'" long. The generic name has been employedpreviously.— Mochlonyw (ibid. 121 note), established for Corethra velutina,Rutlie (Isis, 1831, p. 1205), which differs from Corethra, &c., by theshortness of the first joint of the feet, [one fourth the length of thesecond; an extinct species is M. sepultus in amber.] — Hamasson(ibid. 115, pi. 1, f. 1-5), beyond question identical with Phlebotonms,Rond. ; the species observed by Loew, in Hungary , Wallachia , andConstantinople, II. minutus, is probably Bibio papatasii , Scop.— Liponeura(ibid. 118, pi. 1, f. 6-10), for a species found in Silesia, L. cinerascens, agreesin many respects with Blepharicera, Macq., and Asthenia, Westw. (Report1843, p. 185, and 1842, p. 293), and is very probably not distinct, sup-posing that Westwood and Macquart may have overlooked the peculiar struc-ture of the feet, with the last joint toothed below and the claws serrated.

Macquart (Ann. Soc. Ent. Pr. ii, 69, pi. 11) has given additional par-ticulars of his genus Blepharicera. (Rep. 1843, p. 185.) He had previouslyknown only one sex, which he took for the male, on account of the eyesmeeting. He has since obtained the other sex, which, from the form of theabdomen behind, must be the male; it has also longer legs and broader wings,but what is remarkable, the eyes are smaller, separate, and composed of equalfacets. '1 lie eyes are hairy ; the last joint of the palps in the g long andflexible, as in Tipula. The assemblages of these males were seen alsoperforming their evolutions in the air at a greater height than the others.

Loew (Ent. Zeit. 324) divides Lestremia into two subgenera, Lestremia■with fifteen joints in the feelers of the g, and Cecidogona with eleven. Ofthe latter he has described a new species, L. earned , found at Posen.

[Rondani (Mem. ditterol. iii, Annali di Bologna, vi)has proposed severalnew genera, viz, of the Cecidomyini, which he distinguishes from the fol-lowing tribe by the shortness of the first joint of the feet and the constantabsence of eyelets (ocelli), 1 . Brachyneura (fuscogrisea , new species), 2.Dasyneura. iluteofusca, new species, and obscura , new species), differing from
