Aphiochæta cilipes n. sp. 
Female . Length 2*75 mm. Brownish-yellow, head black and abdo¬ 
men in part black ; legs yellowish testaceous, the hind femora and also 
the tibiæ tipped with black. Wings pale yellowish. Front sligthly but 
distinctly wider than high, brownish near the lower margin. Frontal 
chætotaxy rather peculiar ; the ocellar row straight as usual, middle 
row very strongly bowed downward. Aside from these there are only 
four more reclinate bristles placed in a pair on each side near the 
lower angle, one above the other. The four proclinate bristles large 
and well-developed especially the upper pair which are widely sepa¬ 
rated and higher up than usual. Antennæ small, oval, testaceous, the 
arista very weakly pubescent. Palpi large, strongly bristly. Proboscis very 
short, fleshy. Cheeks each with a pair of very stout downwardly directed 
bristles and a smaller series of four or five in front of these. Post¬ 
ocular cilia strong. Dorsum of thorax strongly arched with a single pair 
of dorsocentral bristles and only two marginal scutellar ones. Abdomen 
mostly black, irregularly marked with yellow. First to fourth segments- 
each with a narrow yellow posterior border, the second yellow on the 
sides and the fourth on the middle. Second segment with a bunch of 
black bristles on each side. Legs long and very stout, the posterior 
femora much thickened, less than four times as long as broad and 
ciliated below on the apical half with a series of long curved black 
bristly hairs. Four posterior tibiæ strongly setulose, the bristles of tho 
middle pair twice as long as the width of the tibia and those of the 
hind pairs which are arranged in two series fully as long as the width 
of the tibia. Middle tibia with one very long spur and hind ones each 
with one long and three short ones. Wings long, the costal vein 
reaching distinctly beyond the middle, its cilia of moderate length. 
First vein attaining the costa one half the way from the humeral cross¬ 
vein to the tip. Furcation of third vein forming an angle of about 
forty-five degrees, the cell thus formed of moderate size; fourth vein 
curved at the base and straight at the apex ; fifth, sixth and seventh 
nearly straight, all of them strong. Halteres pale. 
One female from Sattelberg, Huon Gulf, New Guinea, May 1899 
(Biró). 
This species is related to A. nigriceps Loew of North America 
and A . melanocephala v. Boser of Europe. From the first it is distin¬ 
guishable by the strongly bristly tibiæ the middle pair being distinctly 
setulose, by the shorter costal cilia, and the absence of a second pair 
of scutellar bristles. It differs from melanocephala which has also simi-
