larly bristly tibiæ by the very short costal cilia which are very long 
in the European form, and by the longer costal vein which extends 
distinctly beyond the middle of the wing. 
Aphiochæta fumipennis n. sp. 
(Plate VIII, fig. 8.) 
Female. Length 2—2*5 mm. Black, antennæ and palpi brownish- 
yellow ; four anterior trochanters and tibiae, and all tarsi brown. Wings 
strongly infuscated, dark brown. Front very shining, with a very few 
fine scattered hairs, distinctly higher than wide. Ocellar tubercle and 
median frontal groove present, well-defined. Four proclinate bristles, 
the lover ones much weaker than the upper pair, a pair of reclinate 
ones at each corner; middle row curving strongly downward medially; 
ocellar row straight. Antennæ small, oval, with a strongly pubescent 
arista. Palpi small, their bristles stout only at the tips. Postocular cilia 
stout, cheeks each with three downwardly curving macrochætæ. Thorax 
longer than usual, the mesonotum sub-shining and strongly hairy, with 
only one pair of dorsocentral macrochætæ. Scutellum twice as wide 
as long, with two marginal bristles. Abdomen slender, the second seg¬ 
ment elongated, nearly as long as the third and fourth together. Geni¬ 
talia pale. Legs stout, but not especially thickened, the posterior femora 
less than one-fourth as broad as long. Middle tibiæ microscopically 
setulose, hind ones more strongly so, the bristles about one-half as 
long as the width of the tibia. Middle tibiæ with a single long slender 
spur, hind ones with one long and one much shorter one. Wings very 
long and narrow, strongly infuscated, more especially so along the 
veins. Costal vein reaching distinctly beyond the middle of the wing; 
third vein near to the costa for its entire length. First vein meeting 
the costa closer to the humeral cross-vein than to the tip of the third. 
Cell formed by the furcation of the third vein, very small and short. 
Costal cilia very short and thickly placed; fourth vein slightly but 
evenly arcuate, faintly recurved at the tip. Fifth broadly bent at its 
middle ; sixth sligthly sinuate ; seventh distinct and nearly straight. 
Halteres wholly black, except the basal articulation of the pedicel which 
is pale. 
Two female specimens from Sattelberg, Huon Gulf, New Guinea, 
May 1899 (Biró). 
At first glance this species might very readily be confounded with 
the European Aphiochaeta minor Zeit, on account of its polished 
front, infuscated wings, short costal cilia and setulose hind tibiæ. It
