500 morsitans, 552 palpalis, and 1,500 tachinoides. G. tachinoides is considered to be the most important fly, because it has now been shown to be a carrier of sleeping sickness and is also responsible for the death of large numbers of cattle; it was found to be able to subsist successfully on human beings and their stock in the practical absence of game, and its breeding habits, about which nothing was known previously, have been fully elucidated. A permanent camp has now been established in Kano Province for the purpose of carrying out experimental tests of various. possible control measures on a practical scale against G. tachinoides, A pathologist, Dr. W. A. Young, has just been added to the staff to assist in trypanosome examinations.

Gold Coast.-In August and September, 1922, Dr. J. W. S. Macfie made a survey of the tsetse-flies occurring in the vicinity of Accra. Only two species were found, G. palpalis and G. longipalpis, and these frequented the low hills to the north and west of the town. The large plain round the town is unsuitable for the flies, and it is very unlikely that they can establish themselves there; the nearest point at which they were found was about six or seven miles to the west. In the circum- stances the expense of inaugurating measures for the elimination of the flies does not appear to be justified at present.

Sierra Leone.-Prof. B. Blacklock of the Sir Alfred Jones Memorial Laboratory has agreed to carry out certain experiments in connexion with tsetse-flies and cattle in the vicinity of Freetown, but no details are available as to the work contemplated or accomplished.

REPLIES TO CIRCULAR LETTER AS TO HOLDING THE NEXT ENTOMOLOGICAL CONFERENCE IN 1924 ÖR 1925.

* No. 89.

Remarks.

Prefers 1924, as he will be on leave. Considers it advisable to utilise the opportunity afforded by the British Empire Exhibition (1924), as a consider- able number of officers, directly con- cerned with agriculture and forestry, will be in England during that period. Considers that the occasion of the Empire Exhibition would appear to be appro- priate for the holding of the Conference (1924).

Remarks.

In favour of the next Imperial Entomo- logical Conference being held in 1924 during the period of the British Empire Exhibition.

Considers there are obvious advantages for holding the Conference during the period of the British Empire Exhibition (1924) provided that there are matters of Imperial importance to discuss.

In favour of 1925 for financial reasons. -

Thinks it would be most beneficial if the Conference coincided with the British Empire Exhibition in 1924. It should in many cases facilitate the attendance of interested persons other than the dele gates. Unlikely that he will be deputed to attend as he is not due for leave until 1925,

1924 would suit better than 1925, as the Pusa Entomological Meetings are held in the odd years. Hopes to be able to

attend the next Conference.

Agrees that 1924 might perhaps be pre- ferable to 1925 for this meeting in view of the British Empire Exhibition. Un- likely that Ceylon will be represented by an Entomologist if 1924 agreed to. 1925 would be more convenient for Ceylon. The holding of the Imperial Entomo- logical Conference in 1924 instead of 1925 would suit him personally very well, since he hopes to be on leave during the former year.

Apparently 1924 would be as suitable for the next Entomological Conference as 1925.

It would be a great advantage to have the next Imperial Entomological Confer- ence at the time of the British Empire Exhibition (1924). It would be killing two birds with one stone, as some of the Entomologists could be detailed to look after exhibits.

Does not know whether it would be advis- able to change the year already suggested for the Imperial Entomological Confer- ence; possibly it might be better to keep to the original plan rather than hold the Conference in 1924, as it is probable that our meetings would be less interfered with if they were held in 1925 as decided upon previously.

Thinks it would be an excellent idea if the next Imperial Conference of Economic Entomologists was held next year (1924) in London when the British Empire Exhibition is held.
