large ones on the scutellum. The scutellum bears a few, 
lateral, tine, black hairs. The pleura are dark brown, 
yellowish on the metapleura and upon the suture between 
the pteroplenra and mesoplenra. The scutellum has a 
prominent wide preapical depression. The squamae are 
pale yellow with dark brown border and fringe. The 
halteres are orange with pale yellow knob. Legs: the 
femora are very dark brown, the hind pair black becom- 
ing deep brown distally. All of the tibiae are very dark 
reddish sepia. The tarsi are all nearly concolorous with 
the tibiae. The middle and posterior basitarsi are a little 
lighter brown in color. Pile of the legs almost entirely 
black. Wings: hyaline except for a pale yellowish brown 
tinge which seems to be largely caused by the villi but 
may be partly caused by the wing itself. There are sev- 
eral brown spots on the wing. There is a quite long, 
deep brown spot at the confluence of the subcosta and 
costa which is about three or four times as long as wide ; 
the apex of the costal cell is barely included in this spot ; 
beyond this brown spot, in nearly the middle of the stig- 
mal area of the subcostal cell, there is a faint rectangu- 
lar brownish smudge or spot. There is a darker brown 
spot covering the furcation of the third vein at the base 
of the submarginal cell and immediately below it. There 
is a trace of brown about the remaining central cross- 
veins. The marginal cell is widely open. Abdomen: 
the first segment is brownish yellow, the second has a 
pair of prominent, distinct, narrowly separated, rounded 
and horizontally elongate triangles of brownish yellow. 
The remainder of this segment is shining black. The 
third, fourth and fifth segments are quite black with a 
faint, opalescent greenish reflection which in some lights 
is a pale brassy or reddish. First and second sternites, 
except the posterior margin of the second, together with 
the basal margin of the third sternite, brownish yellow. 
Remainder of sternum shining black with sparse subap- 
pressed pale yellow pile.
