426 Mr. J. R. Malloch on Faotic Muscaride. 
on upper margin in front of spiracle. Abdomen ovate ; 
~ basal sternite bare. Fore tibia without a median bristle ; 
mid-tibia with three or four posterior bristles ; hind femur 
with short fine bristles on antero-ventral and postero-ventral 
surfaces ; hind tibia with two or three antero-dorsal and two 
antero-ventral bristles, the calear short. Costal thorn short ; 
fourth vein not curved forward at apex. 
Female.—Differs from the male in having the frons over 
one-third of the head-width. 
Length 9-10 min. 
Type, male, allotype, and five male paratypes, Estcourt, 
Natal, ix.-x. 1896 (G. A. K. Marshall). 
Genus ALLUAUDINELLA, Giglio-Tos. 
This genus was erected by Giglio-Tos for the reception 
of one species, bivittata, Macquart, described from Isle de 
France. In his recent paper on the genera of Anthomyiide, 
Stein placed seven other species in the genus. I have not 
seen all of these species, but from an examination of the 
genotype apd some of them I am convinced that there are 
at least two distinct, though closely allied, genera involved. 
Both genera may be distinguished from their allies by the 
broad thorax and abdomen, moderately widely separated 
eyes in both sexes, the frons of the female being but little 
wider than that of the male, the hairs on prosternum, 
pteropleura, and basal abdominal sternite, and the remark- 
ably short stubby spines on the upper sides of the palpi. 
This last character readily separates the genera from their 
nearest allies. 
The two genera which have been confused may be 
separated as follows :— 
Alluaudinella, Giglio-Tos. 
Propleura bare in centre; pro- 
episternum hairy ; prosternum with 
a few setulose hairs; metanotum 
pilose on lateral elevation ; third 
wing-vein bare at base above and 
below. 
Genotype, bivittata, Macquart. 
Ethiopomyia, gen. n, 
Propleura hairy in centre ; pro- 
episternum bare ; prosternum hairy; 
metanotum with fine hairs on 
lateral elevation; third wing-vein 
setulose at base above and below. 
Genotype, Mydea gigas, Stein. 
I have before me an African species of Alluaudinella which 
agrees in structure and chetotaxy with the genotype, but 
differs as stated below.
