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.
