third vein is exceedingly small and the fourth vein is distinctly recurved 
at the base ; seventh vein strong. Legs rather slender, middle and po¬ 
sterior tibiæ moderately setolose. Knob of halteres black, the stalk 
yellowish. 
Described from a female specimen collected at Vilcanota. Type in 
the collection of the Hungarian National Museum. 
This pretty species comes closest to A. aurea Ald., but differs by 
its larger size, different color, very minute costal cilia, and bristles on 
the second abdominal segment. I was at first inclined to consider it as 
a well marked variety of aurea , hut it is quite distinct morphologically.

There are two specimens from Vilcanota which evidently belong to 
this species, despite the great geographical separation in habitat.

Two specimens, one from Vilcanota and another from Callanga, do 
not seem specifically distinct from this wide-spread and extremely variable 
species. The veins are blacker then in any European or North American 
specimens that I have seen and the costal cilia are a trifle less closely 
placed.
