EXTINCT EMPIDIDZE : 
FOSSIL SPECIES AND GENERA 
All the described fossil Empidida come from the Tertiary. Some more recent species 
of Empis and Rhamphomyia are known from copal, but have not been described. Two pre-Tertiary 
species have beeri assigned to the Empididz, namely Empidia Wulpii and Hasmona Leo, but itis not 
at all certain that they belong to this family. The Baltic amber has produced a great number of 
specimens of Empididz; Meunier called attention to fifteen hundred inclusions that he had studied ; 
but the descriptions and figures too often miss the salient characters to be of much value in deciphering 
phylogeny.

It may be stated that the Tertiary Empididz almost all belong to genera of the present 
extinct genera, which have been assigned to this family.

Legs robust, front femora thickened, with two flexor rows of pale short, sparse hairs, front tibiae outwardly ciliate on
