I04 
DIPTERA 
pi'oximad of the proximal end of the R-M crossvein; first anal vein delicate, short, incomplete (Allodia, 
Winnertz) or entirely wanting (Brachycampta, Winnertz), second anal delicate and incomplete. 
The characters given by Winnertz for distinguishing Allodia from Brachycampta are as follows : 
In Allodia (PI. 6, Fig. 18) the first anal vein though short is more or less distinct; in Brachy- 
campta (PI. 6, Fig. I 7) it is wanting; in the latter the fork of the cubitus is sometimes formed as in 
Rhymosia, the base of the fork being retracted proximad of the proximal extremity of the R-M crossvein, 
while in Allodia this is not the case. These characters, while sufficient to separate most of the European 
species thus far described, fail utterly for some of the North American still undescribed forms, and for 
this reason, the two genera are combined.
