and the femora denticulate beneath, founded on a new species from an undeter-mined locality; Campylocera , with the third antennal joint rounded beneath,with a new species from Senegal ; Acanthineura, characterized by spinouswing nervures, with a new species from Bengal;—in the Sepsid®: Omalo-cephalct, remarkable for a flat posteriorly attenuated head, with a new speciesfrom Guiana ;—in the Leptopodites: Cardiacephala (Calob. longipes, F., Wd.);—in the Hydromyzid®: Blepharitarsis, with simple anterior femora and cili-ated posterior tarsi, with a new African species.

Goureau (Ann. d. 1. Soc. d. Fr., 2 ser. i, p. 77) bred from Helix conspur-cata , a Fly, which he has described under the name of Melancphora helicivora.The larva is probably the same as that which had been already observed byRudolphi in the same Snail. It was located in one of the antennae.

Guerin (Rev. Zool. p. 202) has communicated a “ Note monographique”on the genus Rutilia, Rob., in which he is the first to separate theMusca mirabilis of the ‘Voyaged. 1. Coquille’ as a distinct new genus,Formosia, agreeing with Amenia, Rob. (M. leonina,Y7 &..) in having the antennalsetae plumose, but differing in the conjoined eyes of the male, and the narrowtarsi with very long claws and much extended pulvilli, an arched (notstraight,) transverse nervure at the apex of the wings, and broad abdomen,somewhat emarginate at the extremity. Rutilia differs from it in the simpleantennal set®. The author enumerates 14 species of this genus: (1) R.regalis, Guer.; (2) R. imperialis, G., n. s.; (3) R. formosa, Rob.; (4) R.decora , n. s., though perhaps scarcely differing from (a) R. splendida (Muse,spl., Don.), with which the author conjoins M. australasia, Griff.; (6) R.lepida, n. s.; (7) R. inornata , is Tachina imista , Wied.; (8) R. Besvoidyi(R. vivipam, Rob.); (9) R. Dtirvillei , Rob.; (10) R. vivipara {Tack, vivip.,F., Wd.) ; (11) R. simiaia iiMusc. sinuata, Don.); (12) R. speciosa, Er.; (13)R. fulvipes, Guer., which, however, does not differ from the preceding, forthe differences adduced by the author are in part individual, and in partowing to misapprehension, because Guerin regards the portion of the thoraxsituate anteriorly to the transverse suture, peculiar to the Muscari®, as theprothorax; (14) R. vidua, which is, however, distinct from the rest in severalpoints, as Macquart had correctly recognized, who, in consequence, consti-tuted from it a distinct genus, Amphibolia.

As Musca (Sarcophagd) Icemica, White has characterized a new Fly(Dieffenb. Travels, ii, 291, n. 136) : Black, with greenish abdomen, legs andhead yellow.

A review of the Silesian species of the genus Psila, Meig., has been givenby Schummel (Arb. u. Verand. der sohles. Gesells., p. 186); among them aretwo new : Ps. dispar, the male of which has curved and clavate posteriorfemora, and Ps. abdominalis, 3"' long, rusty yellow, with black spotted headand thorax, and black abdomen.
