248 INSECTA, 
Empis, Lin.—mpides, Lat. 
Closely allied to Asilus in the form of the body and the position 
of the wings, but with the proboscis perpendicular or directed back- 
wards. The head is rounded and almost globular; the eyes very 
large. 
These Insects are small and live on prey and the nectar of flowers. 
The last joint of their antenne is always terminated by a biarticu- 
lated or short stilet, or by a seta. The males of some species—Hi- 
larie—have the first joint of the anterior tarsi strongly dilated. 
Some have triarticulated antenne. 
Sometimes the last joint forms an elongated cone. 
Here the proboscis is much longer than the head; the biarticu- 
lated stilet terminating the antenne is always short. The palpiare 
always turned up. 
Epis, proper. 
Such in Europe is the 
E. pennipes, Fab.; Panz., Faun. Ins., LXXIV, 18. Black, 
with obscure wings; posterior legs of the female furnished with 
hairs resembling feathers. 
RampHomyia, Meig. 
Only differing from Empis by the absence of a little transverse 
nervure in the end of the wing(1). 
There, the proboscis is hardly longer than the head. 
Hiraria, Meig. 
Where the antenne are terminated by a little biarticulated sti- 
let(2). 
Bracuystoma, Meig. 
Where the stilet is extended into a long seta(3).
