Genus MIKIOLA Kieff. 1896, type Cccidomyia fagi Hart. 

 Antennal segments 22 to 24, the flagellate ones stemmed in the 

 male, subsessile in the female ; palpi quadriarticulate. Venation similar 

 to that of Phvtophaga rigidcv, closely related to, if not identical with 

 Phyiophaga. Europe. 



Genus JANETIELLA Kieff. 1897, type /. thymi Kieff. 

 The third vein unites with costa well before the apex of the wing,, 

 a character separating it from the preceding genus. Antennal seg- 

 ments 12 to 16, the flagellate ones stemmed in the male, subsessile in 

 the female ; palpi quadriarticulate. Europe, North America, South 

 America. 



Genus OLIGOTROPHUS Latr. 1805, type Tipula juniperina Linn. 

 A large form with 20 antennal segments, the flagellate ones 

 stemmed in the male, sessile in the female; palpi probably quadri- 

 articulate, though Kieffer states that these organs are triarticulate, a 

 condition true of the American forms provisionally referred to this 

 genus. Specimens of this type species in the British Museum, iden- 

 tified by Winnertz, have the general appearance of Phytophaga rigid(C, 

 Europe, North America, South America. 



Genus LYCIOMYIA Kieff. & Jorg. 1910, type L. gracilis Kieff. & Jorg. 



Antennae of female with 17 segments, remarkable because of the 

 five or six slightly looped circumfili on the flagellate segments, the 

 fifth cylindric, with a length about 2j/< times its diameter and with 

 a short stem. Palpi triarticulate. South America. 



Genus ULEIA Riibs. 1905, type U. clKsitr Riibs. 

 Antennal segments 22 to 25, the flagellate ones with a short stem. 

 Closely related to the preceding genera and separated therefrom by 

 the bi- or triarticulate palpi and the thickly scaled legs. South 

 America. 



Genus RHOPALOMYIA Riibs. 1892, type Oligotrophus tanaceticola Karsch. 

 Antennal segments 12 to over 20, the flagellate ones stemmed in 

 the male, usually subsessile in the female; palpi uni- or biarticulate ; 

 terminal clasp segment of the male short, stout, fusiform; ovipositor 

 of the female fleshy, at least moderately long, not enlarged ; terminal 

 lobes rather short and stout. Europe, North America, South America.
