ASPHONDYLIARI.^ 



Key to the genera.* 



a\ Ovipositor protractile, aciculate or nearly so, the terminal clasp seg- 

 ment of the male usually uni- or bidentate. 

 b^. Palpi quadriarticulate. 



c'. Flagellate antennal segments with long whorled hairs and two 

 strongly sinuous and anastomosing circumfila, especially in the 

 male. 

 d\ Ovipositor aciculate, without lamella apicad; larval breastbone 



bidentate Schizomyia Kieflf. 



d.-. Ovipositor subaciculate, with two very small lamellse apicad; 



larval breastbone unidentate Kiefferia Mik. 



c". Flagellate antennal segments with short hairs, not whorled. 



ci\ Flagellate antennal segments sessile, without an appreciable stem. 

 e\ Claws much longer than the pulvilli; the basal segment of the 

 ovipositor with rows of minute spinules. 



Tetrasphondylia Kieff. 

 e-. Claws as long as the pulvilli; the first segment of the ovi- 

 positor finely striate, without spinules. 



Parasphondylia Kieff. 

 d'. Flagellate antennal segments subsessile, with a stem about one- 

 fourth the length of the basal enlargement; claws shorter than 



the pulvilli Xenasphondylia . Felt. 



6'. Palpi bi- or triarticulate, rarely uniarticulate. 



c*. Third vein uniting with the margin near the apex of the wing, 

 cf. Circumfila in the female consisting of two comparatively simple 

 bands, 

 e*. Terminal clasp segment of the male uni- or bidentate, not 

 pectinate. 

 /'. Subcostal cell normal, not opaque, the ovipositor with a lobed 

 pouch proximad, not vesiculate basad. 



Asphondylia H. Loew. 



(Syn. Monasphondylia Kieff.) 



/". Subcostal cell opaque, the ovipositor with a globose, striate 



basal enlargement Bruggmanniella Tav. 



e-. Terminal clasp segment of the male pectinate. 



/'. Terminal clasp segment apical; ovipositor subaciculate, with 

 submedian groups of hairs on the distal segment. 



Proasphondylia Felt. 

 f. Terminal clasp segment of the male subapical, the ovipositor 



probably as in Schizomyia Bruggmannia Tav. 



d'. Circumfila in the female forming five irregular, anastomosing 



bands; ovipositor as in Asphondylia Oxasphondylia Felt. 



C-. Third vein uniting with costa near the distal fourth. 



cr. Palpi triarticulate, the circumfila low, very irregular, tei-minal 

 clasp segment slender, unidentate, dorsal and ventral plates 



deeply emarginate Acroectasis Riibs. 



b\ Palpi uniarticulate. 



c\ Terminal clasp segment of the male subapical, conical. 



Houardiella Kieff.
