DIPTERA OF AUSTRALIA, 
piceous-castaneous, nitidous. Palpi yellowish-brown. Thorax 
piceous-castaneoiis, nitidous, with two longitudinal slightly con- 
vergent single rows of short brown hairs extending to the 
scutellum ; the lateral margins and scutellum setose; humeri 
tij)ped with yellowish ; scutellum pitch-brown. Pleurie piceous- 
castaneous. Halteres very pale yellowish : the apical half of the 
club deep brown, with a short fine pubescence. Abdomen twice 
the length of the head and thorax taken together, narrowed at the 
base and extremity, in the middle narrower than the thorax ; the 
segments piceous-castaneous, yellowish on the anterior border, 
the first segment being more than half yellow, the last entirely 
brown ; densely clothed with a long brown pubescence ; forceps 
rather wider than the terminal segment, its last joint short, 
bidentate, densely pubescent. Legs densely covered with a brown 
pubescence. Coxie of the fore-legs yellow, brownish at the apex, 
densely setose in front ; those of the intermediate- and hind-legs 
with the apical half piceous-castaneous. Femoi’a of the fore- and 
intermediate-legs ochraceous-brown, the first pair paler than the 
othei’s ; of the hind-legs piceous-castaneous, somewhat ochraceous 
at the base and towards the apex. Tibiae and tarsi dusky, almost 
cinereous-brown. Wings almost hyaline, with three distinct 
fuscous spots ; the first, a narrow irregular nebulous band, 
stretches obliquely across the wings from below, and a little 
})Osterior to, the junction of the first longitudinal vein with the 
costa to the posterior angle, bordering a yellow patch between 
the fourth and fifth longitudinal veins, and extending behind it 
in the posterior angle ; a more or less cuneate spot, having its 
base on the posterior margin, and enveloping the tip of the fifth 
longitudinal vein, runs obliquely to the anterior branch of the 
fourth longitudinal at a point opposite to the root of the fork of 
the third longitudinal vein ; the third spot is a broad undulated 
transverse band near the apex of the wings, just enveloping 
anteriorly on its inner side the anterior branch of the second 
longitudinal vein, extending on each side of the tip of the anteidor 
branch of the foui’th longitudinal vein on the posterior margin. 
Besides these markings there is an indistinct longitudinal fuscous
