ABSTRACT
The British Museum has already dealt with the Mosquitoes and Tsetseflies, and it is now proposed to publish on similar lines a further series of monographs on the other blood-sucking forms. The material at present at our disposal, however, is insufficient for this purpose, and it is therefore hoped that all medical men and naturalists residing in British Colonies, or in the tropics in any part of the world, will make special endeavours to obtain specimens and send them addressed to the DlRECTOR, BRITISH MUSEUM (NATURAL HISTORY), CROMWELL ROAD, LONDON S.W., together with notes on the names, habits, and distribution of the insects. This appeal is made especially to the medical officers of the Foreign and Colonial Services, to the medical officers ofthe Navy, Army,
and Indian Services and to all official representatives of H.M. Government in foreign parts.
