ENTOMOLOGY 947 
In the female from Stanleyville the infuscation of the wing is somewhat more 
extended than figured by Griinberg, the spots at the base of the second to fifth 
posterior cells being more or less fused with the smoky basal third and dark 
median cross-band, the latter being considerably wider than in Griinberg’s 
figures; brown spots are present at the apex of second and upper branch of third, 
and at the forking of the third longitudinal vein; in the distal corner of the upper 
basal cell a round, dark brown spot is conspicuously set off. In the male, the 
markings of the wing are more as figured by Griinberg, but the fifth posterior 
cell lacks a dark spot in the base. 
The males I have seen from the Belgian Congo fit the description of Surcouf’s 
T. vittata, which I believe is identical with 7. akwa. The author has failed to 
point out how the two are to be distinguished. 
The eyes in life, as observed in the female from Malela, are uniformly colored, 
without bands or other markings.

An interesting feature of these flies is the roof-like position which the wings 
assume in the living insect at rest, when they ‘“‘meet together at the base and 
then diverge slightly, sloping somewhat like the roof of a house’”’ (Austen). 
Haematopota, though very widely distributed, appears to be mainly an Old- 
World type. In the New World, only three species are known from North 
America and the genus is entirely absent from tropical America; but it is repre- 
sented in Argentina and Chile by a special subgenus, Archiplatius. The genus is 
unknown from Madagascar and the other islands of the Malagasy Region, as 
well as from Australia. On the African continent, however, it is unusually de- 
veloped, since of over two hundred described species no less than one hundred
