one and slightly nearer to it than to the upper supraantennal, the 
bristles of the lower row and the upper supraantennals placed in 
a nearly straight transverse line; upper supraantennals about in 
the same distance from each other as the inner bristles of the 
middle row, the lower pair a little more approximated and some- 
what weaker than the upper. Antennæ black, of ordinary size, 
or perhaps somewhat small, arista distinctly pubescent. Palpi yel- 
low, of ordinary size and armature. Thorax black; mesopleura 
bristly, the bristles equal. Scutellum with two bristles. Abdomen 
black, rather tapering. Hypopygium brownish black, small or of 
medium size, a little higher than long, without bristles but with 
some small hairs on the sides below; ventral plate (so far as I 
could see) blackish; anal tube small, brown. Legs brown or yel- 
lowish brown, hind tibiæ as long as the three first tarsal joints, 
the bristles small and very delicate. Wings slightly yellowish or 
greyish tinged, veins yellow; costa not quite to the middle, about 
0,48 of the wing-length, costal divisions proportionately about as 
4—2—1 ; angle at fork somewhat large; costal cilia unusually long; 
fourth vein a little curved at the origin, but very indistinct or 
interrupted at the base. Halteres dark, blackish brown. — Female. 
Quite similar, costa not longer, fork more acute; halteres a little 
paler. Length about 1,2 mm. 
From superciliata the present species is distinguished besides 
by the longer costa by the hairs on hypopygium and the dark 
halteres.

A deep black species related to hirticrus Schm. and nigripcs 
Wood but amply distinet. 
Male. Frons black, low, about twice as broad as long; brist- 
les strong, inner bristle of lower row in the same height as the 
outer and the bristles of the lower row and the upper supraanten¬ 
nals placed in a straight transverse line; the inner lower bristle a 
little nearer to the outer than to the upper supraantennal; the supra¬ 
antennals of the same or nearly the same size, the upper pair in
