Genus LOBODIPLOSIS Felt 1908, type Mycodiplosis acerina Felt. 

 Antennal segments 14. the flagellate more or less trinodose, the 

 circumfili and setx nearly e<|ual. J'alpi quadriarticulate ; basal clasp 

 segment with a distinct lobe apically, the terminal clasp segment there- 

 fore subapical. North America. 



Genus ANTICHIRA Riibs. 1910, type A. striata Riibs. 

 Allied to the preceding genus, the basal clasp segment with a large, 

 hyaline lobe at the internal apical angle. Europe. 



Genus COQUILLETTOMYIA Felt 1908, type Mycodiplosis lobata Felt. 

 Distinguished from the two preceding genera by the setose basal 

 lobe on the basal clasp segment and remarkable because of the strongly 

 chitinized ventral plate or harpcs. North America. 



Genus FELTIELLA Riibs. 1910, type F. tctranychi Riibs. 

 Allied to the preceding and presumably separable therefrom by the 

 ventral plate and harpes being as in Lcsfodiplosis Kieff. Europe. 



Genus KARSCHOMYIA Felt 1908, tyi)e Mycodiplosis viburni Felt. 

 Separated from the four preceding genera by the absence of a 

 'distinct lobe on the basal clasp segment ; flagellate antennal segments 

 of the male trinodose; terminal clasp segment subfusiform, greatly 

 'dilated and much shorter than the basal clasp segment. North 

 America. 



Genus MYCODIPLOSIS Riibs. 1895, type Diplosis coniophaga Winn. 



Antennal segments 14, binodose ; palpi quadriarticulate; terminal 

 clasp segment not abnormally produced or subfusiform: ventral plate 

 not produced, the lobes of the dorsal plate not divided, cleft or trian- 

 gularly emarginate ; ovipositor short. Europe, North America. 



Genus CLINODIPLOSIS Kieff.* 1894, type Diplosis cilicnis Kieff. 

 T'laced Iktc by Riibsaamen on accotmt of the dentate anterior 

 claws. Separated from Mycodiplosis by the greatly elongate, emar- 

 ginate ventral plate. The dorsal plate is deeply cleft and triangularly 

 emarginate. Euroi)e. 



Genus DIADIPLOSIS new genus, type D. cocci new species. 

 The unidcntate rniterior claws and binodose antennae of the male, 

 with the three circumfili show a relation, to ]\lycodiplosis Riibs. and 

 its allies from which it is easily separated by the triarticulate palpi. 



* Species previoii.sly referred to this genus belong to the recently erected 

 Parallelodiplosis Riibs.
