Psyche 
[October 
ened; second with a very inconspicuous tuft of minute bristles 
laterally, otherwise the first four segments are practically bare; 
fifth and sixth with scattered fine bristly hairs. Hypopygium 
small, almost bare. Wings long and quite narrow; costa ex- 
tending to barely beyond the middle, the costa and second vein 
close together; costal cilia closely placed and rather short, about 
three times as long as the thickness of the costa; first section as 
long as the second and third together, the third fully half as 
long as the second; fork of third vein acute; fourth vein gently 
and evenly curved, with recurved tip; fifth almost straight; 
sixth very weakly sinuate; seventh gently curved. Legs rather 
slender; front tarsi not thickened. Middle tibia with delicate 
but distinct setulse; those of the hind tibiae rather strong, in a 
single line just inside the seam; hind metatarsi conspicuously 
spinose beneath. 
Type from Taihoku, Formosa, April 1912 (Sauter). 
This species resembles the Formosan A. canaliculata Brues 
in the mesopleurse and wings, but differs by the different pro- 
portions of the costal divisions and much shorter costal cilia. 
Among the European species it will run to A. armaia Wood in 
LundbeclFs table (Diptera Danica, pt. 6, p. 219) from which it 
differs by the brown wings, darker palpi, shorter first costal 
division, and concealed ventral process of hypopygium. 
Aphiochaeta picta Lehmann. 
A single female of this species from Kankau, July 1912, con- 
siderably extends the range of this species which is already known 
from Europe, North America and southern Africa. 
Aphiochaeta lanceolata sp. nov.'
