INSECTA DIPTERA. 189 



and the femora denticulate beneath, founded on a new species from an undeter- 

 mined locality; Campylocera, with the third autennal joint rounded beneath, 

 with a new species from Senegal ; Acanthineura, characterized by spinous 

 wing nervures, with a new species from Bengal ; in the Sepsidae : Omalo- 

 cepfiala, remarkable for a flat posteriorly attenuated head, with a new species 

 from Guiana ; in the Leptopodites : Cardiacephala (Calob. longipes, F., Wd.) ; 

 in the HydromyzidsB : 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 Ply, which he has described under the name of Nelancphora helicivora. 

 The larva is probably the same as that which had been already observed by 

 Rudolphi 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 the 

 Musca miraltilis of the ' Voyage d. 1. Coquille ' as a distinct new genus, 

 Formosia, agreeing with Amenia, Rob. (31. leo>ih/a,Wd.) in having the antennal 

 setae plumose, but differing in the conjoined eyes of the male, and the narrow 

 tarsi with very long claws and much extended pulvilli, an arched (not 

 straight,) transverse nervnre at the apex of the wings, and broad abdomen, 

 somewhat emarginate at the extremity. Rutilia differs from it in the simple 

 antennal setae. 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, u. s., though perhaps scarcely differing from (5) R. splendida (Muse, 

 spl., Don.), with which the author conjoins M. australasiae, Griff. ; (6) R. 

 lepida, n. s. ; (7) R. inornata, is Tacliina inusta, Wied. ; (8) R. Desvoidyi 

 (R. rh-ipara, Rob.) ; (9) R. Durvillei, Rob. ; (10) R. vivipara (TacJi. vivip., 

 F., TFd.) ; (11) R. simtata (Muse, simtata, Don.) ; (12) R. spedosa, Er. ; (13) 

 R.fah-ipes, Guer., which, however, does not differ from the preceding, for 

 the differences adduced by the author are in part individual, and in part 

 owing to misapprehension, because Guerin regards the portion of the thorax 

 situate anteriorly to the transverse suture, peculiar to the Muscariae, as the 

 prothorax ; (14) R. vidita, which is, however, distinct from the rest in several 

 points, as Macquart had correctly recognized, who, in consequence, consti- 

 tuted from it a distinct genus, AmpJiibolia. 



As Musca (Sarcophoffo) leemica, White has characterized a new Fly 

 (Dieffeub. Travels, ii, 291, u. 136) : Black, with greenish abdomen, legs and 

 head yellow. 



A review of the Silesian species of the genus Psila, Meig., has been given 

 by Schummel (Arb. u. Yerand. der schles. Gesells., p. 186) ; among them are 

 two new -. Ps. dispar, the male of which has curved and clavate posterior 

 femora, and Ps. abdominalis, 3'" long, rusty yellow, with black spotted head 

 and thorax, and black abdomen.
