DOLICHOPID/E. 



A new species of Rhaphium from Gothland is described by Steinhammer, and 10 



new species of Dolichopus by Wahlberg, in the ' Proceedings of the lloyal Academy 

 of Stockholm,' 1850. 



MlTSCID.E. 



A memoir on the Silesian species of Tetanocera, by Dr. Scholtz, containing de- 

 scriptions of 18 species, appears in the 'Proceedings of the Entomological Section of 

 the Natural History Society of Silesia,' for 1850. 



M. Macquart has continued his descriptions of the European Tachenaria? (Ann. 

 Soc. Ent. Fr. viii. 419), containing the genera Phorocera (19 species), Frontina (3 

 species), Metopia (9 species), DeGeeria (21 species), Masicera (HI species). Four 

 crowded plates represent the wings and profile of the heads of the species, with full 

 figures of the four first-named genera. The species are parasitic on Lepidoptera, ex- 

 cept the MetopioB, which infest the fossorial Hymenoptera. 



The continuation of M. Robineau Desvoidy's memoir upon the Myodaires or 

 Muscidae found in the environs of Paris, has appeared in the Ann. Soc. Ent. Fr. ix. 

 177. The genera here treated upon are Thryptocera (5 species), Herbstia (1 species), 

 Aetia (2 species), Osmaoa (I species), Ramburia (1 species). The larvae of the species 

 whose habits have been observed, reside in the bodies of the larva? of Tineidae. A fur- 

 ther continuation, containing Zonia and the allied genera, appears in the 3rd trimestre 

 of the same volume of the ' Annales.' 



The natural history of numerous small species of Muscidae, the larvae of which 

 mine the leaves of different plants, together with that of the various Tchneuroonidae 

 and Chalcididffi which are parasitic upon them, has been described and illustrated 

 with figures by Colonel Goureau, (Ann. Soc. Ent. Fr. ix. 131). 



M. Robineau Desvoidy has described in the 'Revue Zoologique,' 1851 (p. 147), 10 

 species of Muscidae obtained by Col. Goureau from the chrysalides of various Lepido- 

 tera, chiefly Tortricidae, which roll up the leaves of different kinds of fruit-trees. A 

 second memoir by the same author, on species of Muscidae, the larvae of which mine 

 the leaves of different plants, appears in the same work, (pp. 229, 391). 



M. L. Dufour communicated to the Academie des Sciences, on the 11th of Au- 

 gust, 1851, the history of a species of Muscidae, Hyalomyia dispar, the larva of which 

 resides as a parasite within the body of a perfect beetle, Brachyderes lusitanicus, the 

 spiracles at the extremity of its body occupying one of the spiracles of the perfect bee- 

 tle, (Rev. Zool. 1851, p. 408; and Ann. Nat. Hist. viii. 425). 



A valuable memoir by M. Guerin-Meneville, has been presented to the Academie 

 des Sciences, on the natural history of the Oscinis Oleae, a small fly which deposits its 

 eggs in the young fruit of the olive, within which the larva resides, thus often doing- 

 great injury to the crop, and deteriorating the quality of the oil, (Rev. Zool. 1851, 241). 



A curious circumstance connected with the natural history of Musca vomitoria and 

 fulvibarbis, has been observed by M. Blanchard, (Ann. Soc. Ent. Fr. ix. p. lxii.) A 

 specimen of Platydactylus muralis, an Algerine reptile which had been fed upon these 

 insects, and throve upon them, was at length observed to have its bowels distended, 

 and shortly afterwards died, when its intestines were found filled with nearly full- 

 grown larvae of these flies, which had been swallowed at the time when ready to depo- 

 sit their eggs, and these had been hatched in the stomach of the reptile. A similar 

 circumstance had also occurred with a green lizard fed by M. Gratiolet.
