This is one of the best defined and most natural groups among 

 the Anthomyiidce. It includes the Ghorellice of R. Desvoidy, so named 

 from the habit of the males to perform choral dances in the air. The 

 peculiar structure of the last two longitudinal veins of the wing (see 

 fig.*) is common to this and the three following allied genera, viz., 

 Ccelomyia, Haliday, Piezura, Rondani, and Azelia, Desvoidy. 



* Wing of H. aprica.
