yellowish at their tip, shortly brownish haired. Prothorax one and 
a third times longer than broad, narrowed towards the apex and 
with rounded front angles, brown, with a very narrow, blackish 
median streak, disappearing towards the hind margin, and with 
broader, blackish, lateral horders; the hind and lateral margins with 
blackish tubercles, bearing long, yellowish brown bristles. Meso- 
and metathorax pale brown; scutella yellowish. Abdomen greyish 
brown, yellowish haired; the segments with yellowish hind and 
lateral margins. Legs yellowish 
white; tibiae with a dark band in 
the middle and at the apex; the 
bands are rather indistinct on the 
hind tibiae; tarsal joints with dark 
tip. Wings hyaline, shining, almost 
without any yellowish tinge. Hind 
margin near the apex somewhat 
concave. Nervation yellowish 
white, but many of the longitu¬ 
dinal veins with shorter or lon¬ 
ger brownish streaks; some of 
the cross veins totally or partly 
brown and in a few cases also brownish shaded. Pterostigma 
yellowish with brownish spots. The nervature with erected, dark 
or pale hairs. In the hindwing only some few cross veins near 
the hind and the apical margin are shaded, observable by one 
small and one larger spot. 
Length of forewing 18 mm; that of hindwing 16 mm. One 
female specimen (bred), Sydney, Coll. Ti Ilyard. 
As the apex of the abdomen was somewhat shrivelled I can 
not say anything about the apical appendages, but it seems to me, 
that they are formed on the same plan as in chrysops.
