3. After full discussion, in which the procedure of the Tropical Diseases Bureau was compared with that adopted by the Bureau of Entomology, it was agreed that, bearing in mind the object of the Review of Applied Entomology, the present system of abstracting and indexing should be continued.

4. The Sub-Committee considered the further suggestion that in the Review of Applied Entomology the group to which an insect belongs should be indicated whenever an insect is mentioned. The Sub-Committee agreed as to the desirability of indicating the group or order, but considered that the indication now given in the abstracts as published in the Review was sufficient for all practical purposes.

5. It was agreed that when new volumes are started the price of the Review of Applied Entomology and the Bulletin of Entomological Research should be raised in consequence of the increase in the cost of paper, printing, etc.

41881

The arrangements decided upon by the Sub-Committee were as follows:-

Bulletin.Annual subscription to be raised from 10s. to 15s. (post free).

Cost of separate parts to be raised from 4s. to 5s. (post free). Review. Annual subscription for sections "A" and "B" to be raised from 12s. to 188. (post free); annual subscription for section "A" only, from 88. to 128. (post free); annual subscription for section "B

only, from 58. to 6s. (post free). Cost of separate parts of sections "A" and "B" to be raised to 18. 4d. and 8d. respectively.

Back parts of Bulletin to be sold at the "part" rate (not post free). Back parts of Review to be sold at the " volume rate (not post free). The prices laid down at the date of publication to be adhered to in selling back numbers and parts, unless the stock gets very low, when the ques- tion of raising the price should be brought up.

NORTHERN RHODESIA.

THE ADMINISTRATOR to THE BRITISH SOUTH AFRICA COMPANY. (Received in Colonial Office, 17th July, 1919.)

SIR,

(No. 258.)

Administrator's Office, Livingstone,

Northern Rhodesia, 20th May, 1919

I AM directed to forward, for the consideration of the Board, copy of a memo- randum by the Principal Medical Officer on the subject of entomological research towards the study of Glossina morsitans in Northern Rhodesia.

I am, &c.,

J. C. C. COXHEAD, Acting Secretary to the Administration.

Enclosure in No. 93.

Medical Department, Livingstone,

Northern Rhodesia, 13th May, 1919. Entomology: Glossina.

ENTOMOLOGICAL research which had been directed towards the study of Glossina morsitans was discontinued in December, 1915, on the release of Mr. LI. Lloyd for active service in Europe. The staff had previously been depleted by the release of the late Mr. R. A. F. Eminson for a similar purpose, and by transfer of the late Mr. Dollman and Mr. Otter to the Native Department.

Mr. Lloyd has recently resigned his appointment as Chief Entomologist. The present position is, therefore, that should the work be continued a new staff will be required.

In considering the question of the resumption of this work, the following points are submitted for His Honour's consideration.

It is generally supposed, although no definite information on the subject is available, that the fly areas in this territory are increasing in extent, and that such increase constitutes a menace to the whole territory.

231

The results of previous work carried out by Messrs. Lloyd, Dollman, and Eminson in this territory, while they threw considerable new light on the subject, have not determined a practicable method for dealing with the problem.

It should be appreciated that the problem presented for solution is an immense one; that years of co-ordinated and systematic work will be required; that the expenses involved will be large; and that it is only by centralization and a pooling of resources that such can be obtained.

It is thought that the essential conditions on which life and propagation of Glossina depend will be found to be similar in all parts of the continent, and, there- fore, that it will prove unnecessary in investigating the subject to provide facilities for local research.

It is considered that further investigations into the relationship which exists between fly and game are required, and that a careful study of the conditions obtaining in fly areas where game is almost completely absent is most likely to give results which will assist in determining this relationship.

In a recent speech at the opening of the Legislative Council the Adminis- trator of Southern Rhodesia laid some stress on the proposed work in this con- nexion in that territory, and intimated that the sum of £1,000 had been set aside for the purpose of preventive measures.

The Union Government are now undertaking research into the game and fly question in Zululand.

(A suggestion has been made, for His Honour's consideration, that the Union Government be given facilities to undertake this research in this territory, where it is considered that the material available is probably more suitable than in Zululand.)

The sum of £1,000 has been provided for in the current year's health estimates for entomology.

The above sum represents, roughly, the salary and travelling axpenses of one entomologist only; it excludes the possibility of experimental research. No more than the compilation of facts resulting from trained observation could be expected from its expenditure. These would, no doubt, be useful if systematically compared with other such observations made in the various parts of Africa; there is, how- ever, at present no machinery for this purpose.

The tsetse fly problem is one which affects the whole continent of Africa, and a factor in its future will have, perhaps, the biggest individual influence as development.

The methods of investigation at present adopted by the various Governments and Administrations in Africa-namely, each individually engaged in a small way. each handicapped by the need of economy, by the want of opportunity for large experiments, a great many duplicating both the work and the expenditure of the others-will, it is considered, either fail to arrive at a solution of the problem or to realize when the problem is proved to be insoluble.

The benefits accruing locally under the present methods are negligible— practically nothing has resulted.

It was at one time hoped that the entomological staff of this Administra- tion, having had some years' experience both in tropical African conditions, which is probably essential for work in this particular field of research, and with years of experience and observation on such work as has been done on the subject would, in conjunction with the facilities which this territory offers for such research, form a "cadre" for the centralization of such research. Unfortunately for this scheme (with the exception of Major Kinghorn, whose work on the subject in connexion with sleeping sickness is well known, and whose experience of the conditions obtaining in tsetse fly areas is unrivalled) the War has, by the dispersal of all the members of the entomological staff, rendered such impossible.
