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-

uhat 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 siiperciliala 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 hirticriis Schm. and nigripes

Wood but amply distinct.

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
