COENOMYIA. 



GENERIC CHARACTER. 



Antennae porrect, triarticulate, first joint rather 

 long, cylindrical; second, cyathiform; third, 

 conical, eight ringed ; seta none ; palpi elevated ; 

 proboscis short; scutel bidentate; wings hori- 

 zontal, crossed upon the tergum. 



OBSERVATIONS. 



We are indebted to Latreille for this genus, 

 v^hich has been adopted by Meigen, w^ho, in his 

 European Diptera, describes but a single species 

 as belonging to it. Fabricius gave the name of 

 Sicus to this genus, a designation that Latreille 

 had already applied to a very different group. 

 The present name w^ill therefore be considered 

 as having the priority.
