[April 
Antennae wholly black; third joint not as long as wide, some- 
what pointed at tip, arista nearly basal. Lateral and inferior 
orbital cilia whitish, about five to six of the upper cilia on each 
side black. 
Thorax and abdomen green with bronze reflections; meso- 
notum dulled with gray or brownish gray, pleurae with white 
pollen; abdomen with white pollen on the sides. Hypopygium 
(fig. 3) black; its lamellae somewhat angulated and deeply notched 
at tip, yellow with the edge narrowly black, fringed with bristles 
which are deep black in color, some of them flattened, and a 
little enlarged at tip; there appear to be two pairs of inner ap- 
pendages, one blackish and the other yellow. 
Coxae and femora black; tips of coxae and narrow tips and 
the base of all femora yellow, the yellow at base of hind femora 
sometimes nearly reaches their middle. Middle and hind femora 
each with one preapical bristle. Tibiae yellow, posterior pair 
with their tips blackened for nearly one third their length; fore 
tibiae with only two or three slender bristles on upper surface. 
Fore and middle tarsi black from the tip of the first joints; anterior 
pair about as long as their tibiae, their joints in the proportion of 
24-8-6-4-6; hind tarsi wholly black, first joint scarcely as long as 
second. Calypters and halteres yellow, the former with black 
cilia. 
Wings slightly grayish; costa considerably enlarged at tip 
of first vein, this enlargement tapers quite rapidly at first, more 
gradually afterwards and extends nearly to the tip; third and 
fourth veins converge from the cross-vein to their tips, where 
they are about half as far apart as at the cross-vein; last section of 
the fifth vein about one and a third times as long as the cross- 
vein; anal angle rather prominent, its margin nearly parallel 
with the sixth vein.
