OF WASHINGTON, VOLUME XIV, 1912. 49 



Phania as the type of the subfamily, following Brauer & von 

 Bergeustamm, notwithstanding Robiueau-Desvoidy's earlier 

 use of Ocyptera as the type of the group, since Phania is far 

 more typical of the group as a whole and Ocyptera and its 

 derivatives are now dropped. The subfamily is characterized 

 in general by a great or considerable development of the 

 female genitalia and presumably in most cases for the purpose 

 of subcutaneous larviposition or perhaps oviposition originally. 

 I place the Compsilurini here, and probably most if not all of 

 the forms having the habit of subcutaneous larviposition will 

 eventually be found to belong here. The group seems to 

 bear a considerable affinity to the subfamily Phasiinse, which 

 has a corresponding development of the female genitalia for 

 the purpose of subcutaneous oviposition. The Phasiinae are 

 in turn allied with the Conopidse on the same character, 

 though much differentiated from them in others. I can not 

 follow Bezzi and Stein in grouping Cylindrotnyia with the 

 Pseudodexiine and Pyrrhosiine stocks. 



TRIBE EUTHERINI. 



14. Imitomyia, nom. nov. 



For Himantostoma H. L,oew (1863), preocc. by Agassiz, in 

 1862. 



Type: Himantostoma sugens H. Lw., the only species. 

 Syn.\ Himantostoma H. Lw. (nee Agassiz). 

 Repr. habit: Unknown, but judged larviposition. 



SOBFAMILY ERYCIIN^B. 

 TRIBE CROCUTINI. 



15. Crocuta Meig-. (1800). 



Type: Mnsca geniculata DeG., being only species given by 

 Meigen in 1803, as Stomoxys minuta J. C. Fab. (by error ap- 

 pearing irritans), for his Siphona, which is the same genus 

 according to Hendel. 



Syns.: Siphona Meig. (1803); Bucentes Latr. (1809). 



Repr. habit: Host-larviposition (Pantel et al.). 



This compels dropping the time-honored name Siphona and 

 its derivatives. 



TRIBE ERYCIINI. 



16. Huebneria R. D. (1847). 



Type: Tachina a /finis. Fall. , being designation by Robineau- 

 Desvoidy in 1863 of Carcclia nigripes R. D., which is a syno- 

 nym of the above genotype according to Bezzi and Stein. 



Syii.: Exorista Auctt. p. p. (nee Meig., nee B. B.). 



Repr. habit: Host-larviposition (Pantel).
