(Rothwell) have been taken by Major Nurse who also records from the same
district M. rossi and M. culicifacies.

     M. rossi.—I have found during its season in profusion at Delhi in the extreme
south-east, at Umballa and Amritsar in the central portion of the submontane
tract, and at Gujrat and Bhera to the north-west. Taking into consideration
also Adie's observations at Ferozepore and the experience of some other observers,
there can be little doubt that this species is during its season the commonest ano-
pheles throughout at least the eastern half of the Punjab.

     The common anopheles at Dera Ghazi Khan in September was, I am informed
by Major Perry, I.M.S., C. pulcherrima, whilst Captain H. C. Brown, I.M.S., also
speaks of this species as the commonest species at Dera Ismail Khan. It is
possible that towards the west, where the monsoon rainfall is only a few inches,
M. rossi does not flourish to the same extent as further east; but observations
are required on this matter.

     M. culicifacies.—Though it never or very rarely occurs in such profusion as
M. rossi is a very common mosquito and is found not only widely distributed
throughout the Punjab but also at almost all times of the year. I have found M.
culicifacies abundant at Palwal, Delhi, Umballa, Ghagger, Beas, Ferozepore,
Amritsar and Atari. Captain Brown, I.M.S., states it is very common at Dera
Ismail Khan.

     N. fuliginosus.—I have found abundant at Delhi, Armitsar, Lahore, Gujrat
and Ferozepore. It is like the two preceding species common throughout most
of the Punjab.

     N. stephensi.—I have taken at Delhi, Umballa, Beas, Amritsar, and Lahore.
At Delhi this species is found in enormous numbers in the wells of the city, several
hundred larvæ being brought up by a single cast of the net. Its larvæ also swarm
in pools in the river bed of the Jumna and elsewhere. As noted by Dr. Bentley
in the case of Bombay the adults which hatch out from larvæ taken in the wells
are small. Specimens bred from open pools are so much larger that it is difficult
at first to believe that they can be the same species. But I have not been able to
note any marked differences other than in size. Adults hatched out from nymphs
taken on the river bed at Beas in February were small like those from the wells at
Delhi. At Amritsar the species is chiefly found in pools. It occurs also in wells
about the outskirts of the city but not as at Delhi in large numbers.

     C. pulcherrima—Which at the time of its discovery seemed to be almost
peculiar to Lahore is evidently a common Punjab species. I have found it
sparingly at Delhi, Beas, Amritsar, Atari and Lahore.

     M. barbirostris.—I have taken at Atari, Amritsar and at Delhi. It is found
in large open wells, but as a rule single larvæ only are captured. Colonel Adie,
