Genus LOEWIOLA Kieff. 1896, type Diplosis centaurecc F. Lw. 

 Separated from the two preceding genera by the ventral plate, 

 which is as long as the dorsal plate, being deeply bilobed and the 

 ovipositor not longer than the body. The circumfili are slightly pro- 

 duced, the palpi triarticulate, the terminal segment being greatly 

 produced ; ])ulvilli rudinicntary. Europe. 



Genus HAPLODIPLOSIS Riibs. 1910, type Diplosis equestris Wagn. 

 Separated from the preceding genus by the ventral plate being 

 narrowly truncate, not emarginate. Europe. 



Genus MONARTHROPALPUS Riibs. 1892, type Diplosis bit.vi Lab, 

 The binodose antennal segments have short, stout circumfili simi- 

 lar to those of Hormomyia ; the flagellate antennal segments of the 

 female with two rather high circumfili ; palpi uniarticulate, the pul- 

 villi not longer than the claws, the ovipositor terminating in a long, 

 stout, chitinous spine. Europe, North America. 



Genus FRAUENFELDIELLA Riibs. 1905, type F. coiissapocc Riibs. 



Separated from the preceding genus by the ovipositor having two 

 large dorsal lobes apically, the female antennal segments with " worm- 

 like " loops as in Asplwiidylia (presumably like those of the male) ; 

 palpi uniarticulate. South America. 



Genus BRAUERIELLA Kieff. 1896, type Diplosis phillyrccc F. Lw. 

 Apparently closely related to Hormomyia, since the circumfili are 

 nearly equally developed in both sexes ; second node of the fifth 

 antennal segment in the male, with a length two and one half times its 

 diameter; palpi biarticulatc ; pulvilli longer than the claws, ovipositor 

 short, lobed. Europe. 



Genus DICHRONA Riibs. 1899, type D. galianim Rubs. 

 Separated from the preceding genus by the second node of the 

 fifth antennal segment in the male having a length one and three 

 fourths times its diameter, the pulvilli being nearly as long as the 

 claws. Probably cogeneric with the preceding. Europe. 



Genus ORSEOLIA Kieff. and C. MassL 1902, type O. cynodontis Kieff. and 



C. Massl. 



Distinguished from the two preceding genera by the fifth antennal 

 segment of the female having circumfili less developed, while those 

 in the male are more strongly developed; palpi biarticulate or quad-
