A large robust blackish pilose fly, with dense white hairs across base of 

 abdomen. 



$. Eyes bare ; vertex occupied by the large circular ocellar triangle, which

 black area anterior to the posterior ocelli, and clothed with brownish-black 

 hairs (fig. 57) ; front ferruginous, sometimes reddish-grey, a broad velvet- 

 black band across the middle (its form shown in fig. 57) ; across the anterior 

 margin of this band is a furrow, posterior to which the blackish pile, 

 clothing the front, is erect but proclinate anterior to furrow ; lunular 

 area inclined to orange-yellow ; 1st and 2nd antennal joints shiny black, 

 the 3rd transversely oval, brownish-black but with a lighter reflection ; 

 arista orange-red but darker apically ; a broad velvet-black band extend- 

 ing from eye to eye across roots of antennae and upper part of face beneath 

 antennae (fig. 60). Face fulvous, darker in some lights ; oral margin and 

 lower part of face shiny black, as shown in fig. 60 ; a silvery area at lower 

 eye-angle ; a groove across face from eye to eye just beneath the pro- 

 tuberance ; above this groove face clothed with delicate black hairs, but 

 bare below ; face deeply dished on upper half, thence produced to protuber-
