bined discal and second posterior cells (M 2 ), and a short area in 
the tip of the combined third posterior and anal cells (Cu+lst 
An). 
Total length, from notch of fronto-clypeus to apex of abdomen 
(alcoholic specimens): 5.5 to 7.5 mm.; length of wing: 5.5 to 7 
mm.; width of wing: 2.2 to 2.8 mm. 
L. pilosa is isolated in the genus Lynchia , owing to the uni- 
form covering of setulae on thorax and scutellum, the unusual 
development of the pronotum, the crowding of the longitudinal 
veins toward the costa of the wing, and the sexual dimorphism 
in the extent of the microtrichia over the wing membrane. Most 
of these characters differentiate L. pilosa also from the smaller 
species of the genus Lynchia.

This species is now known from Zululand, the Orange Free 
State, Transvaal, Bechuanaland, Southern Rhodesia, Tangan- 
yika Territory, Kenya Colony, Uganda, southern Abyssinia 
and Morocco. It is normally a parasite of the Otitidae (Bus- 
tards, Koris or Knorhaans) and will probably be found wherever 
these birds occur. In particular, it should be looked for in the 
savannas of the Katanga and the northeastern Uele (Belgian 
Congo), where Bustards are fairly common. The occurrence of 
this fly on Sandgrouse in Morocco is of unusual interest. The 
flies were taken on this host in winter (November 6, 1938). 
Colonel Meinertzhagen (in litt.) points out to me that “Sand- 
grouse inhabit much the same type of country as Bustard and 
in this particular area of Morocco the Bustard is not uncommon 
in spring and summer, but absent in winter. It is also to be 
1 “Paauw” is one of the vernacular names of the Bustards in South Africa.
