CHARLES T. BRUES. 
slender bristles above each coxa and several more at the humerus ; 
metapleura with a short blackened streak just in front and bellow the 
halteres. Abdomen luteous below r , black on segments 3—5 and seven 
above ; dorsal segments one and two stained with fuscous and segment 
six yellow. Sides of abdomen faintly bristly but without a tuft of brist¬ 
les on the second segment; its surface subshining, genitalia yellow. 
Legs slender, all the tarsi especially so ; whitish, more luteous on the 
tibiæ, tips of femora and on the tarsi ; posterior femora blackened at 
the apex. Middle and posterior tibiæ each with a series of small deli¬ 
cate setulæ along the back, just inside the hind edge. Wings (fig. 16) 
narrow, tinged with pale yellow, and with weakly colored veins. Costal 
vein barely exceeding the middle of the wing, with short, but not very 
densely placed cilia ; tip of first vein scarcely nearer to the humeral 
cross-vein than to the tip of the second vein, the latter entering the 
costa at less than its own length from the tip of the costa; fourth 
vein curved at both base and apex, but nearly straight medially, not 
recurved at either base or apex; fifth and sixth each faintly sinuate, 
the wing tip midway between the tips of the fourth and fifth veins ; 
seventh long, almost straight, distinct. Halteres black. 
One female from Toyenmongai. 
This species is rather close to the preceeding in many of its cha¬ 
racters and its separation must depend upon the shorter costal vein, 
evenly curved base of fourth vein, pale antennæ, pale wing veins and 
generally much paler color throughout. 
Aphiochæta Sauteri n. sp. (Fig. 17.) 
Female. Length 2 mm. Brownish testaceous, the head and abdo¬ 
men black, the wings yellowish anteriorly, with strong, dark-colored 
veins. Front black, reddish along the anterior margin, its surface strongly 
grayish pollinose and sparsely beset with minute bristly hairs. Four 
proclinate setæ, the lower pair more approximate and smaller, but not 
greatly reduced; bristles of following row arranged in a pair near each 
anterior angle of the front, the bristles of each pair close together with 
the lateral one very close to the eye, and not much higher up than 
the median one. Bristles of median row four in number, equidistant, 
forming a line which curves slightly downward medially. Ocellar row 
as usual, the ocellar tubercle and median frontal line very distinct. 
Antennæ pale yellow, rounded, not enlarged, with a pubescent arista 
nearly half longer than the head-height. Palpi of the usual length, but 
rather slender, with stout bristles below on the apical half. Cheeks each
