DIPTERA OF AUSTRALIA, 
brown, tinged with ochraceous, with four very long brown 
setse ; metathorax brown. Halteres yellow, with a minute pubes- 
cence. Abdomen much compressed from the sides, twice the 
length of the thorax ; segments brown, all excejit the first and the 
last two with a narrov’^ border of ochraceous posteriorly, the fifth 
and sixth segments ochraceous beneath ; densely clothed with short 
golden-yellow hairs ; ovipositor and terminal lamellte ochraceous, 
pubescent. Legs robust. Coxse and femora bright ochre-yellow ; 
fore coxae densely haired in front ; foi'e femora not as wide as the 
coxae, the hind pair very wide, the latter slightly tipped with 
brown. Tibiae brownish-ochraceous, hind pair slightly tipped with 
brown, the fore pair with a few short spines on the outer side, 
the intermediate pair with three ranges of long spines, one on the 
inner and two on the outer side, the hind pair with two ranges 
of long spines on the outer side. Spurs brownish-ochraceous, 
spines brown. In the fore-legs the taisi more than twice the 
length of the tibiae, the latter rather longer than the metatarsus. 
Wings longer than the abdomen, rounded off at the base, pellucid, 
of a pale brownish-yellow tint, with two small distinct light brown 
spots and faint trace of a third one : the first squarish, between 
the first longitudinal vein and the base of the anterior branch of 
the third logitudinal vein, enveloping the marginal cross-vein, as 
much appearing in the marginal as in the inner marginal cell ; the 
second spot indeterminate, rather paler than the last, about equal 
to it in size, filling up the portion of the marginal cell between 
the tips of the costal and second longitudinal veins, and a short 
distance from the tip of the latter*, extending half-way across the 
first sub-marginal cell ; a little below this starts a very pale narrow 
oblique spot, which continues very indistinctly almost to the 
anterior branch of the fourth longitudinal vein. Marginal cross- 
vein situated at about the middle of the first longitudinal v^ein, 
and over the base of the second sub-marginal cell, the latter- 
sessile ; base of the second posterior cell situated under the base 
of the second sub-marginal cell ; fifth longitudinal v'ein not 
reaching the base of second posterior cell.
