Mr. J. R. Malloch on Exotic Muscaridee. 165 
thorns. Legs long and slender; fore and mid tibize each 
with one antero-dorsal and one postero-dorsal bristle ; hind 
femur with very short weak antero-ventral bristles ; hind 
tibia with one antero-ventral, one antero-dorsal, and one 
postero-dorsal bristle. Inner cross-vein at middle of discal 
cell ; penultimate section of fourth vein over two-thirds as 
long as ultimate section. Lower calyptra much longer than 
upper. 
Length 10 mm. 
Type and paratype, north of Mt. Kenia, British East 
Africa, 8300 feet, 18. 11. 1911 (7. J. Anderson). Two 
females. 
This genus is allied to Limnophora, R.-D., but the absence 
of the posthumeral bristle separates it from that and all 
allied genera known to me. 
Genus Eutimnopuora, Malloch. 
I erected this genus for the reception of three North 
American species in 1920. ‘There are several African species 
which belong to the genus, four of them being in the material 
before me—mervinia, Walker, tonitrui, Wiedemann, versi- 
color, Stein, and fascigera, Stem. Stein lists the four species 
in the genus Limnophora. 
Eulimnophora may readily be distinguished from Limno- 
phora by the presence of a fringe of setulose hairs on the 
posterior margin of the basal abdominal sternite in both 
sexes. The abdominal dorsal markings are usually produced 
forward at the inner extremity of the large spot at or near 
the posterior margin of each tergite, a character which I 
have not seen in the true Limnophora species. 
Genus Limnornora, Robineau-Desvoidy. 
All species of this genus have the prosteraum with setulze 
ou its sides and the third wing-vein with setulze at base. 
The prosternum is larger and more distinctly triangular than 
in Eulimnophora. There are mauy species of this genus in 
Africa, including odsignata, Rondani, simulans, Stein, and 
perfida, Stein, which are in the material before me. 
Limnophora latilamellata, sp. un. 
Male.—Black, shining. Frons opaque brownish black ; 
orbits black, whitish anteriorly ; face, parafacials, and cheeks 
whitish pruinescent. Thorax without differentiated vitte, 
margin pale grey pruinescent. Abdomen with a pair of black
