GENERA REMOVED FROM THE EMPIDID.E (1). 
The following genera have been held by various authors as belonging to the Empididz. The 
resemblances to members of this family have proved to be superficial and the genera have one by one 
been removed to other families. The forms here placed in the Bombyliidz are highly specialized in that 
family, with neuration reduced in accompaniment with their small size. "They can hardly be regarded 
as annectent forms, linking the Bombyliide with the Empidide. because they are more highly 
specialized in other respects than the Hybotinz with which they connect. "Their resemblances therefore 
are to be regarded as parallel developments. The status of the genera in question is given herewith.

Characters. — This genus contains a few small blackish bristleless species that run to the 
Empididz in existing keys of Diptera. The general opinion is that Hilarimorpha belongs to the 
Leptidz, in which family it is aberrent in having minute empodia, reduced tibial spurs and no discal 
cell. Five species have been described. A 
Tyne species : H. singularis, Egger.
