330 Mr. G. H. Verrall’s descriptions of 
joints dull black the former densely clothed with short bristles, first 
joint and basal third of third joint dusted with red pollen, third 
joint a little dilated for basal two-fifths then gradually tapering to a 
blunt end. Style missing in the specimen examined. Face nearly 
all covered with orange pubescence hardly obscuring the ground- 
colour and leaving bare only a narrow shining black middle line; 
the black line against jowls narrow; jowls and lower half of back 
of head with long orange pubescence, which becomes shorter and 
browner on the upper part of back of head but is longer, bent forward 
and orange on the vertex as far forward as the top ocelli, in front 
of which the frontal pubescence is dense, soft and rather upturned 
and when viewed from in front is very inconspicuous, frons moder- 
ately shining blue-black but slightly obscured by dust, lower half 
of sides of frons with an eye-stripe of whitish-grey dust continued 
(but yellower in colour) all down sides of face. Eyes when viewed 
from in front with a narrow conspicuous black band of pubescence 
running down just in front of the middle, and with long rather dense 
whitish pubescence before and behind it; this pale pubescence ex- 
tends all over the rest of eye leaving only just the middle of back 
part bare, and is most dense against the black band. The facial 
pubescence creeps up the sides of the frontal prominence leaving 
only just the prominence bare, and there is no sign of a black band 
of pubescence across frons. 
Thorax dull black (apparently having been cleaned), but probably 
of an aeneous colour in life because the sides are aeneous black, 
scutellum moderately shining black with a tinge of aeneous. Pubes- 
cence equal, all tawny. It is impossible to tell whether stripes are 
present or not. 
Abdomen moderately shining black tinged with aeneous; basal 
segment and a semi-circular depression at the middle of the base 
of second segment, dull black; across the middle of second and 
third segments (just after middle of second and probably interrupted 
on third segment) there may be indications of a very narrow dull 
black band. Pubescence all tawny and short except about basal 
corners of second segment. 
Legs red-tawny, coxae black but even tips of tarsi only a little 
obscured, pubescence abundant on femora, moderate but noticeable 
behind anterior tibiae, and all orange. 
Wings with brownish-orange infuscation about the veins on the 
front part even to tip of wing, also along discal vein to almost end 
of discal cell; discal cross-vein at two-fifths the discal cell; upper 
marginal cross-vein with a slight angle. Squamae glassy whitish- 
yellow, with long yellow fringes. Halteres brownish-orange. 
Length 11 mm. without antennae, which measures 4 mm.
