Microdon aurigaster n. sp. 
Male. Length 9.5 mm. 
Head: entire insect, except antennse, tibise and tarsi, dark 
shining brown, nowhere blackish. Antennse light orange 
brown, elongate, third joint a bit longer than first and three 
times length of second. Arista short, concolorous, quite 
thickened at base; no pedical. Vertex somewhat swollen, 
its pile, that of front and face depressed and golden and 
rather long. Face broad, transversely rugose and grossly 
punctate. Eyes sparse, short, pale pilose. Thorax: whole 
dorsum short, thick, greatly appressed golden pilose, visible 
only from the right angle, but with bands standing out at 
other angles as a transverse sutural band and a prescutellar 
band. Of these bands, only one-half (the right or left half) 
may be seen at one time. Scutellum short, inconspicuously 
golden pilose, with two small close set spines. Squamae and 
halteres brown, the former with a golden fringe. Abdomen: 
apical corner of second abdominal segment, side margins of 
third, its narrow posterior margin and the whole of the 
fused remainder brilliant golden pilose, the pile much ap- 
pressed and set as if it were flowing on each side in diagonal 
and opposed directions. Legs: pile of femora pale, the 
surface of hind femora deeply and grossly punctate. The 
tibise and tarsi light orange brown, remarkably densely 
covered (for tibise) with long golden bristles. Hind tibise in 
the middle and the thickened hind femora basally with dia- 
gonal cicatrices. Wings: on basal anterior border cream yel- 
low, posteriorly grey ; the yellow continuous apically, to bend 
down as a yellow spot towards the tip where on either side 
the wing (basally and apically) is a little darker grey; wing 
else where light grey. A spur is present from third longi- 
tudinal vein but nowhere else. The terminal section of the 
fourth longitudinal vein forms a most pronounced and prom- 
inent outward bulge.
