antennal sockets^ slightly raised on the middle line. Posterior 

 orbits moderately broad, gradually narrowed toward the vertex. 

 Ocelli placed in an equilateral triangle, on a slightly raised tubercle 

 which is widely removed from the imier orbits. Proboscis large 

 and thick, slightly shorter than the head; with broad and long 

 labella which are obtusely pointed at the apex. Palpi compara- 

 tively short and thick, barely one-third the length of the proboscis. 

 Eyes bare, with all the facets approximately equal in size. Anten- 

 nas about as long as the face, of the usual shape in the genus (very 

 much like the drawing of the male antennae of A. ibis in Verrall, 

 British Flies, Vol. 5, 1909, p, 242, fig. 171) ; the two basal joints 

 almost of equal length; the third a little longer, of swollen kidney- 

 shape; arista slender, about one and one-half times the length of 

 the antennae, bare. Thorax and scutellum of the usual shape.

Legs comparatively long and thick. Femora distinctly swollen

 femora; fore tibiae without, middle and hind tibiae with two spurs. 

 Fore tarsi slender, slightly longer than their tibias ; their basal joint 

 e^dindrical, not thickened, about as long as the following four
