 6 to 8 subsessile segments, the second greatly enlarged. 



Micromyia Rond. 

 d". Antennae not very short, the male with 14, the female with 11 

 to 22 antennal segments, the second not greatly enlarged. 



Campylomyza Meign.* 

 e\ Flagellate antennal segments with a more or less distinct col-

 /". Claws arched, enlarged slightly subapicad and with trans- 

 verse striations; the pulvilli about half the length of the 



claws Prosaprionus Kieff. 



f. Claws simple. 



g^. Pulvilli short or rudimentary Aprionus Kieff.

 stemmed disks. 



f. Claws with a minute subapical tooth Monardia Kieff. 



f. Claws simple, a little shorter than the pulvilli. 



Amblyspatha Kieff. 

 e'. Flagellate antennal segments with reniform processes sub- 

 apicad, claws bent at right angles, dilated subapicad. 



Biyomyia Kieff. 

 e\ Flagellate antennal segments with subapical whorls of short, 



stout, usually recurved spines Cordylomia Felt. 



e'. Flagellate antennal segments with series of whorls of short,
