SUBFAMILY ECTOPHASIIN^. 

 TRIBE ECTOPHASIINI. 



4. Ectophasia, gen. nov. 



Type: Syiphus{Thereva) crassipennis J. C. Pab. (female 

 equals T. analis}. C. Fab.), hereby designated. 



Syn.; Phasia Auctt. (nee Latr.). 



Repr. habit. Host-oviposition of flat macrotype egg (Pantel 

 et al.). 



This and 1 call for a complete shift of the name Phasia, 

 which hereafter carries a totally different significance. 



NOTE. Bezzi and Stein indicate Eratia occlusa R. D. (1863) as 

 synonym of above genotype. The description appears to me incom- 

 patible with specimens of crassipennis but conforms much better to 

 those of Elomya lateralis Meig., whose abdominal spots show more- 

 over a tendency toward the trigonal pattern. In the non-existence of 

 Desvoidy's types and improbability of the above synonymy I do not 

 consider the name Eratia available for use here. 



TRIBE RHODOGYNINI. 



5. Rhodogyne Meig-. (1800). 



Type; Musca rotundata L., being the only species given 

 by Meigen with his Gymnosoma (1803), which is manifestly 

 the same genus, according to Hendel. 



Syn. : Gymnosoma Meig. (1803). 



Repr. habit: Host-oviposition of flat macrotype egg (Pan- 

 tel, Towns, et al.). 



This calls for the dropping of Gymnosoma and its deriva- 

 tive names, euphonious and long in use. 



FAMILY MUSCID^E. 



SUBFAMILY MESEMBRININ^. 



TRIBE MESEMBRININI. 



6. Mesembrina Meig-. (1826). 



Type: Musca mcridiaua L., being designation by West- 

 wood in 1840. 



Syn.: Metamesembrina Towns. (1908), which has same 

 type. 



Repr. habit: Dung-larvipositiou, maggot apparently being 

 carried through at least first stage in utero (Portchinski). 



7. Hypodermodes, g-en. nov. 



J^ype: Musca mystacea L,., hereby designated. 



Syti. Meser;ibri)ia Towns. (1908), (nee Meig.). 



Repr. habit: Dung-oviposition of few large eggs, the mag- 

 got omitting its second stage (Portch.). 



This and 6 call for shift of Mesembrina from meaning given 

 in Tax. Muse. Plies (1908).
