of Ctenojphora, if Ctenojrfiora and Tanyptera are kept apart as distinct 

 genera. In 1832, Bridle, overlooking Latreille's work, also founded a 

 new genus (Xiphura) onatrata, and in 1833 lie separated Ct. birhacidata, 

 L., as a distinct genus, Dictenidia, leaving Meigen's two remaining 

 speciesin Ctenopliora, where they have peacefully stood until Coquillett's 

 unwarranted innovation. What Latreille, five years later (in 1910), did 

 with the genus Ctenopliora has no bearing on our nomenclature. 

 Kertesz's citation (Cat. Dipt. II, p. 269) of TanyiAera under the genus 

 Ctenoplwra is wrong. The correct synonymy of these genera is : — 



Tanyptera, Latr. (1805). 

 Xiphura, Brulle (1832). 

 Type: atrata, L. 



Ctenophora, Meig. (1803). 

 Phoroctenia, Coq. (1910). 

 Type : pectinicomis, L.
