OF WASHINGTON, VOLUME XIV, 1912. 45 A READJUSTMENT OF MUSCOID NAMES. BY CHARLES H. T. TOWSEND. In these days dipterological nomenclature is getting a severe shaking up, and the Muscoidea come in for their share. The late resurrection of Meigen's 1800 paper, the recent discovery of various long-perpetuated nomenclatural errors as judged by the rules of the International Code, and the designation of certain genotypes by the late Mr. D. W, Coquillett call for a considerable amount of change in the names of muscoid genera, tribes, subfamilies, and in one notable case a change of family name. These changes are detailed below so far as they are apparent to me at this time. FAMILY PHASIID^. SUBFAMILY PHASIIN^. TRIBE PHASIINI. 1. Phasia Latr. (1804). Type: Syrphus hemipierus J. C. Fab., being the only species given by Latreille, as Thereva coleoptrata J. C. Fab., which is a synonym of the above, according to Bezzi and Stein. Syn.: Alophora'R. D. (1830), Girschner et al., which has the same type. Repr. habit: Subcutaneous oviposition (Pantel, Towns.). This compels dropping of Alophora, which will hereafter be known as Phasia, and likewise changes the meaning of the tribal and subfamily names derived from Phasia. 2. Hyalomyia R. D. (1830). Type: Phasia pitsil/a Meig., being designation by West-wood in 1840. Syn.: Parallophora Girsch. (1888), which has same type. Repr. habit: Unknown, but judged same as Phasia. This compels dropping-of I \irallophora, hereafter to be known as Hyalomyia. 3. Alophorella, g-en. nov. Type: Thereva obesa J. C. Fab., hereby designated. Syn.: Hyalomyia Girsch. (1888) et al. (nee. R. D.). Repr. habit.: Subcutaneous oviposition (Pantel). This and 2 call for a complete shift of the name J/va/t)i\'ia, hereafter to carry a different meaning.
