(5 each), and An. argenteolobatus, An. cyddipis, C. argenteopunctatus,
C. decens, C. telesilla and Uranotaenia bal[ouri (4 times each). The halophilic
mosquitoes A edes durbanensis angolae, C. thalassius and C. tritaeniorhyinchus
were also recorded as associates, each in two of the univittatus
breeding sites. Figs. 5, 6 and 7 illustrate three typical breeding sites
of C. univittatus.
Only 13 9 and 5 were caught as adults, the remainder of our specimens
being laboratory-reared. Of them, 8 9 and 4 were caught at rest
on several kinds of outdoor shelters. Other catches were made by early
morning (6.00-8.00) either in cattle-sheds (2 ?) or in human habitation
(3 9 --one of them fed, in a window trap--and 1 ). Two of these
three females were taken at Calai (inland plateau) while the other one
was caught at Bocoio (ScarpmenU, both localities being at about 1,000
meters in altitude. These observations, showing the predominant zoophily
of C. univittatus in Angola, seem to be in general agreement both with
the findings of Someren et al. (49), in Kenya, and with those of
Hamon (37), in the Upper Volta.
7.5.32 --- Culex (Culex) watti Edwards, 1920
C. 4,atti was not found by the present writers.
The only known records of C. watti in Angola are those by G'andara
(lo) (l), from Dala Tando (14 reared males and females), Portugtlia
(circa Dundo) and Caconda (1 female each).
So far as we know, with the exception of those by Gandara, no
other new distributional data on C. watti were reported anywhere since
the original ones given by Edwards himself (8). As it was noted above
under C. dttttoni, the differences used by Edwards to distinguish watti
from duttoni seem to be more of the kind of an infrasubspecific variation.
In favour of this view is also the assumption of Hopkins (24) that
the larvae of watti (even though not yet described) are
