SUBFAMILY MUSCIN^B. 

 TRIBE STOMOXYDINI. 



8. Haematobia St. Farg. & Serv. (1828), R. D. (1830). 



Type: Conops irritant L,., being designation by Westwood 

 in 1840. 



Syn.: Lyperosia Rdi. (1856-1862), which has same type. 



Repr, habit: Dung oviposition (Riley & Howard). 



Calls for dropping of Lyperosia and reinstatement in the 

 economic literature of the generic name, H&matobia for the 

 horn-fly. 



9. Lyperosiops o-en. nov. 



Type: Stomoxys stimulans Meig., herebj' designated. 



Syn. : Hirmatolia B. B. et Auctt. system, (nee St. Farg. 

 & Serv., nee. R. D., nee Auctt. econom.). 



This and 8 call for shift of H amatol i a from its former 

 significance. 



FAMILY EXORISTID^. 



SUBFAMILY EXORISTIN^. 



TRIBE EXORISTINI. 



10. Exorista Meig-. (1803). 



Type: Musca larvarum L,., being the only species. 



Syns.\ Jachina Auctt. (nee. Meig., nee. B. B ); Eu- 

 tachina B. B. (1889-1893). 



Repr. habit: Host-oviposition of flat macrotype egg 

 (Towns., Pantel, et al. )

 the EXORISTID^ instead of the Tachiuidae. I hereby desig- 

 nate Musca larrarnm Linne (Exorista, larvarum L. , Meig., 

 1803) the type of the family as the form most appropriate to 

 discharge this function. Some may consider Musca grossa 

 L. (Larvavora grossa L., Meig., 1800-1803) entitled to the 

 honor, as being the original Tac&ina, but I believe that usage, 

 propriety and still other considerations call more loudly for 

 the above designation. 



NOTE. In this connection a word may be said on the classification 

 of Girschner, followed by Bezzi and Stein, which groups nearly all of 

 the Muscoidea in the single family heretofore called Tachinidas and 

 hereafter to be known as Exoristidte, the comparatively small remnant 

 of Musca and its allies being thrown into the Anthomyiidae. From a
