6             SUPPLEMENT TO THE ANNUAL REPORT OF THE

              TABLE V.—The parasites found in the blood of children—cont.

       The very high propörtion of malignant tertian in all villages is noteworthy
and would point to the correctness of the local statements about deaths from
malaria.

       Another point is that in 53 per cent of the positive finding gametocytes
(mainly crescents) unaccompanied by a sexual forms were found. This is evidence
of the correctness of chart I (not reproduced), for it is what one would expect to
find after the end of an epidemic. There were practically no cases of acute
malaria at the time of the survey.

       Anopheles surrey—Adult mosquitoes.—There were many culicines, but
anophelines were very few indeed apart from the rather hardy non-carrying
species A. rossi. Seeing that the hot dry season was beginning this is not a
matter for surprise. With difficulty 128 adult anophelines were caught in houses
and cattle sheds in the villages of Mopad, Botlagudur and Inimerla see Tables VI
and VII.

                TABLE VI.—The species of adult mosquitoes caught.

               TABLE VII.—The number of adult anopheles caught, their species, sex and the
                                    result of dissection of the females.

       As is obvious from the tables, adults of species capable of carrying malaria
were found in the two villages of group A, and none such were found in group C.
Villages in group B were not searched, but the scarcity of adults other than rossi
makes this unimportant. All females were dissected, no zygotes or sporozoites
were found. This again is of no importance because of the small number of
adults other than rossi which has never been proved to carry malaria. Although
apart from rossi, so few adults were caught, yet possibly even so the preponder-
ance of culicifacies is rather suggestive of its being the main species carrying
malaria. This is supported by the large number of culicifacies amongst the larvæ
bred out. No conclusive evidence in this respect can be obtained until a second
visit is paid to the area in September. So, for the present, we must presume
that the carriers responsible are all those capable of carrying that were common as
larvæ or adults. As we shall see, these were culicifacies, stephensi and
fuliginosus

       Breeding places.—The survey was made at a time (March) when malaria was
at its lowest, and most of the breeding places were getting dried up or getting
too hot to allow of larval life, the water in places was actually unpleasantly hot
