half the width of the tibia. Wings rather narrow, especially 
toward the tip, the costa and third vein not at all thickened 
apically, unusually far apart toward the base; costa just half 
the length of the wing with very short and densely placed cilia; 
first section as long as the second and third together; third one- 
third as long as the second; second vein very oblique, the cell 
narrow; fourth vein faintly curved near base, straight beyond; 
fifth and sixth each bisinuate, nearly parallel on the basal half 
and strongly divergent apically; seventh almost straight. In one 
wing the fourth vein is furcate near the tip where it gives off an 
oblique forwardly directed branch, an abnormality which I have 
never seen in any other Phorid. 
Type, four paratype males and one female all from Taihoku, 
Formosa, May 1912 (Sauter). 
In Lundbeck’s table of European species (Diptera Danica, 
Pt. 6, p. 212) this runs to A. uligmosa Wood, from which it differ 
by the brownish wings and extremely short costal cilia. The 
thorax is also much lighter colored than in the European species. 
It is not very similar to any described oriental species. 
The female is essentially like the male, with the front tarsi 
equally thickened; the costa is slightly, but quite distinctly 
longer than half the length of the wing. 
Aphiochaeta pedicellata sp. nov. 
9 . Length 2.0 mm. Thorax dull ferruginous, the meso- 
notum fuscous; legs dark brownish yellow; front black, whitish 
pollinose; abdomen piceous or black, the fourth segment with a 
yellowish stripe on each side of the median line; antennae rufo- 
piceous; palpi dark yellow. Wings distinctly tinged with brown, 
venation clear yellowish brown. Halteres light yellow. Front 
broad, fully one-half wider than high; its bristles strong, more 
nearly perpendicular to the surface of the front than usual; four 
postantennal bristles, the lower pair considerably smaller and 
not much more approximate than the upper which are separated 
by one-fourth the width of the front; inner bristle of lowest 
reclinate row midway between the upper proclinate bristle and 
on a level with it; lateral one but little higher, close to the ej^e;
