Synonymy and Types. 



The following is only a partial synonymy of the genera, and many 

 names are retained as valid which future study will degrade to the 

 rank of synonyms. As here given, several changes are made in the 

 names of genera from those adopted by Meade in the Ent. Mon. Mag., 

 1 881-1883. Thus, Hyctodesia is replaced by Phaonia, a much older 

 name ; Spilogaster is united to Mydcca, as Strobl and Stein already 

 have done ; Trichophthicus is a synonym of Lasiops, as stated by 

 Meade, who preferred to perpetuate the error of Rondani rather than 

 to correct it ; Homalomyia gives way to Faniiia, an older name, and 

 Cd'Iomyia becomes a synonym of it, following Strobl and several others ; 

 Choi'tophila and Phorbia, which have been united by Stein and some 

 others, are merged into Pego/nyia, as the slight difference in the color- 

 ing of the legs is hardly of generic importance ; and finally, Melano- 

 chelia is a synonym of Limnophora, as Rondani has already stated in 

 Dipt. Ital., VI, 103.
