the middle, its cilia rather short and fine ; first vein ending a little nearer 
to the humeral cross vein than to the tip of the third; cell at furcation 
of third vein rather large ; fourth vein evenly curved, following ones almost 
straight; seventh distinct. Halteres pale brown. 
One female specimen from Bombay, India (Biró, 1902). 
This species is very distinct by its peculiar coloration, recalling 
strongly the Conicera bicolor described on another page. 
Aphiochæta tibialis n. sp. 
Male. Length L2 mm. Brownish yellow, head black, abdomen piceous, 
hind tibiæ arcuate. Head considerably flattened ; front subshining, faintly 
gray pollino se, broad, but distinctly higher than wide ; vertex elevated ; 
ocellar tubercle large, its marginal groove deep as is also the frontal 
groove which attains the lower frontal margin. Proclinate bristles only 
two in number; next row of four strongly curved downward medially; 
following row straight ; ocellar row as usual. Post-ocular cilia stout, espe¬ 
cially below; cheeks without any strong macrochætæ. Antennæ orange 
yellow, oval and more pointed than usual ; corner where arista is inserted 
black ; arista almost bare. Palpi orange yellow, bristly along entire lower 
surface. Thoracic dorsum more or less yellowish, tinged with brown, 
nearly twice as long as wide, with a single pair of dorsocentral macro¬ 
chætæ. Scutellum subtriangular, as long as wide, marked with three or 
four faint, whitish pollinose, diverging lines on each side, bearing four 
equally strong marginal bristles. Abdomen narrow, piceous, with a few 
scattered bristles, especially toward the apex. Hypopygium not projecting ; 
venter testaceous. Legs testaceous, the tarsi slightly darker, front and 
middle tibiæ distinctly setulose ; hind ones strongly so, the bristles being 
almost as long as the diameter of the tibiæ which are thickened, and 
distinctly arcuated near the base ; posterior femora slightly thickened, 
external edge curved, internal one straight. Wings hyaline, the veins 
weak brownish; costal vein falling distinctly short of the middle of the 
wing, its cilia rather long and thickly placed ; first vein ending midway 
between the humeral cross-vein and tip of third ; cell at furcation of third 
vein small; fourth vein more strongly curved b as ally ; fifth and sixth 
faintly bisinuate; seventh distinct. Halteres testaceous. 
One male, Matheran, East India (Biró, 8. July 1902). 
The present species is most easily recognized by the swollen, ar¬ 
cuated hind tibiæ, and by the form and chætotaxy of the thorax.
