Key to North American genera 



a Ovipositor protractile, aciculate or nearly so, the terminal clasp segment of 



the male usually uni- or bidentate 



b Palpi quadriarticulate, the flagellate antennal segments with long, whorled 



hairs and two strongly sinuous and anastomosing circumfili, especially 



in the male 



c Ovipositor aciculate with lamellae apically; larval breastbone bidentate 



Schizomyia Kieff. 

 bb Palpi bi- or triarticulate, rarely uniarticulate 



c Circumfili in the female consisting of two comparatively simple bands 

 d Terminal clasp segment of the male uni- or bidentate, not pectinate 

 e Subcostal cell normal, not opaque, the ovipositor with a lobed pouch 

 proximally, not vesiculate Asphondylia H. Lw. 



aa Ovipositor exserted, apically with lobes or triangular plates; terminal clasp 

 segments of the male usually serrate apically 

 b Palpi quadriarticulate 



c Terminal clasp segment of the male apical; third and fourth antennal seg- 

 ments fused, the circumfili usually with many fine reticulations in the 

 male, the pul villi usually shorter than the claws Cincticornia Felt 

 bb Palpi triarticulate 



c Terminal clasp segment of the male serrate apically 



d Circumfili of male coarse, very irregular, there being four or five trans- 

 verse fill to a segment, the plates of the ovipositor triangular

Antennae consisting of 14 cylindric, sessile or subsessile segments, 

 those of the male slightly shortened distally and each with remarkably 

 stout, elevated, strongly convolute circumfili. Palpi with 4 segments. 

 The basal clasp segment of the male genitalia projects well beyond 

 the insertion of the terminal clasp segment, which latter bears 



1 Judging from larval characters this genus is closely related to, and may pos- 

 sibly be a synonym of Uleella Rubs., a genus founded upon a larva.
