12 . A. longiciliata n. sp. . 
A species related to nigripes Wood and Beckeri Wood but dis¬ 
tinet from both. 
Male. Frons greyish black, somewhat broader than long; brist¬ 
les strong, inner bristle of lower row somewhat below the outer 
and nearer to it than to the upper supraantennal; supraantennals 
unequal, the lower about half as strong as the upper; the upper 
supraantennals more approximated than the inner bristles of the 
middle row, the lower direct beneath the upper. Antennæ of or- 
dinary size, blackish, arista distinetly pubescent. Palpi yellow, well 
developed, with ordinary bristles. Thorax black; mesopleura bristly, 
the bristles equal. Scutellum with two bristles. Abdomen black, 
very slightly greyish, somewhat robust. Hypogygium not small, 
greyish, produced downwards and thus higher than long; there are 
no hairs or bristles visible; ventral plate yellowish, rounded at the 
end, reaching about to the end of the hypogyium ; anal tube some¬ 
what small, brownish, a little paler at apex, the apical hairs small. 
Legs light brownish, hind tibiæ only slightly longer than the two 
first tarsal joints, the bristles small. Wings somewhat brownish 
tinged, veins brown, the thin veins somewhat strong and the seventh 
vein only sligthly finer than the others; costa not reaching to the 
middle, 0,47 of the wing-length, costal divisions proportionately as 
11—5—3; angle at fork somewhat acute; costal cilia long, longer 
than usual; fourth vein evenly curved. Halteres black. Length 
1 ,6—2 mm. 
From superciliata Wood which may have the costa on the 
border between short and long the present species is distinguished, 
besides by the longer costa, by the unequal supraantennals, black 
halteres, not straight seam on hind tibia and larger size.
