mz Mr. J. R. Malloch on Ewotie Muscaridee. 
first wing-vein bristly on upper side on entire length, third 
bristly at base above and below, not curved forward at apex ; 
arista very short-haired ; frons of female as in Phaonia ; 
hind tibia with a weak bristle at middle on postero-dorsal 
surface. 
Most closely allied to Pseudophaonia, Malloch, and 
Cyrtoneurina, van der Wulp. From the former it is 
separable by the setulose wing-veins, and from the latter by 
the straight third vein, bare prosternum, and long anterior 
intra-alar bristle. 
Genotype, the following species. 
Steinella prima, sp. n. 
Male and female——Black, slightly shining, with a faint 
bluish tinge. Head black, basal two antennal segments 
yellowish ; orbits and face with whitish pruinescence ; palpi 
black. Thoracic dorsum quadrivittate, the spaces between 
vittze densely brown pruinescent. Abdomen with bluish-grey 
pruinescence, a moderately broad dorso-central vitta, and 
faint lateral checkerings black, the pruinescence on fourth 
tergite in female yellowish. Legs black, tibiz brownish 
yellow, darkened except at bases in male. Wings clear, 
cross-veins inconspicuously infuscated. Calyptrz white, 
margins dark. Halteres yellow. 
Male.—Kyes almost bare, separated by a little more than 
width across posterior ocelli; orbits narow, setulose to anterior 
ocellus ; parafacial narrower than third antennal segment; 
cheek higher than width of third antennal segment; arista 
pubescent. Thorax without presutural acrostichals, with 
four pairs of postsutural dorso-ceutrals, the prealar bristle 
long. Abdomen ovate, depressed; hypopygium small. 
Fore tibia unarmed at middle on posterior surface; mid- 
tibia with two posterior bristles; hind femur with some 
widely spaced bristles on antero-ventral surface and some 
finer bristles on basal half of postero-ventral ; hind tibia with 
one antero-ventral, one autero-dorsal, and one postero-dorsal 
bristle near middle. Outer cross-vein curved ; veins 3 and 
4 subparallel. 
Female.—F rons over one-third of the head-width ; orbits 
narrow. In other respects as male. 
Length 6 mm.
