On specimen from Toyenmongai. 
This species is very much like the preceeding one, but seems to 
be distinguishable from it very easily by the characters given in tho 
key to the species on a previous page. 
Aphiochæta chipensis n. sp. (Fig. 15.) 
Female. Length 2 mm. Brownish yellow, the tips of the hind 
femora blackened and the abdomen black. Wings slightly, but distinctly 
infuscated. Front quadrate, light brown, faintly pollinose, infuscated 
abouth the ocelli and below them. Ocellar tubercle and median frontal 
line present. Lower margin of front with only one pair of proclinate 
bristles, the lower pair represented by minute hairs, scarcely longer 
than the scattered hairs which cover the front. Next row above forming 
a pair of bristles at each side of the lower margin, the lateral one close 
to the eye and scarcely higher 
than the median one which is 
equidistant between the eye 
margin and the proclinate 
bristle. Middle frontal row of 
four bristles forming a nearly 
straight Ime. Ocellar row as 
usual. Postocular cilia slender, 
not enlarged. Antennae small, 
rounded, fuscous, with a stout pubescent arista, one-half longer than head 
height. Cheeks each with two downwardly directed macrochætæ and a 
series of long bristly hairs running up each eye to the antennal cavity. 
Palpi brownish yellow, long, but not swollen ; bristly below on the apical 
half, the bristles slender and arranged in two series. Mesonotum subshi¬ 
ning, clothed with soft fuscous hairs and bristly along the lateral margins ; 
one pair of dorsocentral macrochætæ and two long scutellar bristles, 
the scutellum very sharply convex behind and more than half as long 
as broad. Pleuræ brownish testaceous, much lighter ihan the meso¬ 
notum, entirely bare, except for two very minute bristles above the 
base of each fore coxa. Abdomen black, subopaque and beset with 
minute scattered bristly hairs; genitalia yellow; none of the segments 
elongated, the second on the sides with several bristles. Legs mode¬ 
rately stout, but none of the tarsi thickened. Hind femora slender, very 
distinctly blackened at the apex. Middle and postorior tibiæ with mode¬ 
rately strong setulæ forming a single series just inside the hind edge. 
Wings (fig. 15) long and narrow, the costal vein nearly two thirds as 
Fig. 15. Aphiochaeta chipensis, wing.
