Tribe Eph.kim vnxi 



Tribe Epigrimyiini is close to Phaniinae, but best retained as a 

 separate tribe not actually coming within that subfamily. It in-

 within the subfamily Pyrrhosiinse. 



Tribe Leucostomini 

 Genus Leucostoma Meigen 



Lcucostonia nigricornis Townsend. — The species nigricomis and 

 senilis are distinct, and may be recognized by the characters given in 

 the descriptions. L. nigricomis is essentially a southwestern and 

 western species, and senilis an eastern and northeastern species. 

 The former has the antenna? more uniformlv blackish, the second
