This species is not known to me ; it would appear from the 

 description that its chief differences from the Macquart species, to 

 which it must be very nearh' aUied, Ues in the black-brown not 

 reddish antennae ; thorax with no reddish stripes or colour ; legs 

 with the base of the tibiae red, not black as in the Macquart species, 

 the posterior tibiae of which onh^ are reddish. The shape of the 

 forehead and frontal callus appears identical in both species.
