two near apex on antero-ventral surface, and one near middle 
on postero-ventral ; hind tibia with two postero-dorsal, one 
antero-ventral, and three antero-dorsal bristles. Costal thorn 
of moderate length. 
Length 6°5 mm. 
Type, Higo Samula, Abyssinia, 30. x. 1911 (R. J. Stordy). 
Most closely resembles Teniomyia maculithorax, Stein, 
but the colour of the legs and bristling of hind tibia differ. 
Genus TaniomyIA, Stein. 
I have in another magazine cited as the type of this genus 
fascigera, Stein. I have before me a female of this species 
from Oshogbo, 8. Nigeria (Dr. T. G. F. Mayer), which 
enables me to designate as a character for distinguishing 
Teniomyia from Emmesomyia, Malloch, and Pegomyia, R.-D., 
the presence of a number of setulose hairs on the upper part 
of the pteropleura. In Emmesomyia there is a fine bristle on 
the upper margin at the middle of the pteropleura, and in 
Pegomyia the pteropleura is bare. I have not seen any 
species of Teniomyia from America, but several species of 
Emmesomyia are found there. 
Genus RuHoDESINA, nov. 
Generic characters—Apical genital segment in female 
with a pair of stout claw-like thorns. Third wing-vein with 
a few setulose hairs at base above and below. Lower

- postero-dorsal bristles. 
Genotype, the following species. 
Rhodesina ignobilis, sp. n.

thorax except laterally, the greater part of pleura, tergites of

white. Halteres yellow. 
Frons a little less than one-third of the head-width ; orbits 
narrow, each with three supraorbital and two infraorbital 
bristles, the lower supraorbital directed forward; inter- 
frontalia with a pair of strong cruciate bristles; third 
antennal segment over three times as long as second ; arista 
with the longest hairs not as long as width of third antennal 
segment ; parafacial in profile almost invisible; cheek not 
as high as width of third antennal segment. One strong
