with two stout downwardly directed macrochætæ and a series of long 
bristly hairs running up each eye to the antenna. Mesonotum rather 
narrow, brownish yellow, subshining clothed with minute black hairs 
which are longer behind ; bristly along the sides ; one pair of dorso- 
central macrochætæ. Scutellum evenly arcuate behind, less than half 
as long as broad, with two very stout marginal bristles. Pleuræ testa¬ 
ceous, paler than the mesonotum ; mesopleura bare, but the propleura 
bears along its posterior margin, both above and below, a series of 
fine backwardly directed bristles. Abdomen dull black, the second se¬ 
gment dull luteous and the sixth more or less brownish yellow ; sides 
of the dorsal segments with a few black hairs, and a tuft of larger, 
but not very conspicuous ones at each side of the second segment. 
Venter and genitalia pale yellow. Legs rather stout, the anterior tarsi 
slyghtly shortened and thickened. Posterior femora blackened on the 
apical fourth. Middle and posterior tibiæ each with a single series of 
quite long setulæ along the 
posterior side, just inside 
the hind edge. Wings (fig. 
17) of moderate size, faintly 
yellowish anteriorly. Costa 
reaching a trifle beyond the 
middle of the wing, its cilia 
rather short and closely pia- Fig. 17 . Aphiochaeta Sauteri , wing, 
ced ; third vein lying further 
from the costa than is usual ; first vein entering the costa midway 
between the humeral cross-vein and the tip of the second vein. Second 
vein forming a rather narrow cell at its furcation since the third vein 
curves forward the tip ; entering the costa its own length before the tip 
of the latter. Fourth vein more strongly curved basally, recurved at 
the extreme base ; fifth slightly bent near the middle ; wing tip midway 
between the apices of the fourth and fifth veins ; sixth and seventh 
slightly sinuate. Halteres black. 
A female from Chip Chip, February 1909. 
This resembles A. chipensis most closely, but differs by its shor¬ 
ter costa, broader wings, more bristly propleura, light-colored antennæ, 
and by the presence of the lower pair of proclinate frontal bristles.
