CHAELES T. BEITES. 
little weaker than the median pair. Mesopleura above bristly, beset 
with numerous small bristles, of which one or two are much larger 
than the others. Abdomen deep ochre-yellow, blackened at the tip, its 
surface opaque, bare ; none of the segments elongated, but the second 
at the sides with a tuft of black bristle-like hairs. Legs rather slender, 
pale testaceous yellow, the tips of the posterior femora blackened; 
middle and posterior tibiæ sparsely but quite distinctly setulose just 
inside the posterior edge; all tarsi long and slender. Wings (fig. 8) 
hyaline, tinged with yellow along the veins; costal vein just attaining 
the middle of the wing, its 
cilia closely placed, short 
and fine ; first vein ending 
a little closer to the tip of 
the third than to the hume¬ 
ral cross vein ; second en¬ 
tering the costa sharply, 
close to the third, so that 
a small narrow cell is for¬ 
med by its furcation ; fourth 
vein weakly curved on its basal half, straight beyond ; fifth bent mainly 
near its middle, ending as far from the wing tip as does the fourth ; 
sixth nearly straight; seventh straight, distinct. Halteres deep yellow, 
concolorous with the body. 
Described from a female collected at Takao, November 1, 1907.

bristles, the median pair very much weaker than the lateral ones and 
placed almost in front of them; next row above of four, placed toward 
the lower angles of the front as usual ; row above of four equidistant 
bristles which form a line that curves down strongly at the middle; 
ocellar row as usual. Postocular cilia long, but not especially stout; 
cheeks each with a pair of stout downwardly directed macrochætæ and 
a row of smaller ones extending from them to the base of each antenna. 
Antennæ yellowish brown, moderate in size, slightly oval, with a slightly 
pubescent arista as long as the head-height. Palpi moderately large and
