species encountered in The Gambia. The catches of mosquitoes by men using the device actually exceeded those of the controls. The description of these devices, by their manufacturers, as “mosquito repellers” would seem to claim a significant degree of protection from mosquito attack for the user. This is not supported either by earlier trials against diurnal Aedes spp. in North America (KUTZ, 1974; GORMAN, 1974) or by the results reported in this letter against nocturnal West African species. In the latter context, reliance on such gadgetry for protection from mosquitoes could prove disastrous where it certainly offers no alternative to antimalarial prophylaxis and more conventional personal protection measures such as nets and chemical repellants.

A preliminary epidemiological survey of human leishmaaiasis in Tuscany .%-In their paper under this title, BETTINI, PAMPIGLIONE & MAROLI (1977) kindly mention two papers of mine, both in Italian, on leishmaniasis and Phlebotomus in Italy, the second of which, written in collaboration with I. NERI, deals with an area of Tuscany: Monte Argentario. From the text of their paper I realize that the authors believe that Monte Argentario was the only area of Tuscany where my studies on Phlebotomus and leishmaniasis were made. Under the “Vectors” section they state that “so far the only studies on possible vectors of leishmaniasis have been done in the Monte Argentario area”. Apparently a more comprehensive paper, written in English (CORRADETTI, 1962) escaped their attention. That paper was presented to the First International Symposium on Leishmaniasis held in Rome jointly by the Societa Italiana di Parassitologia and the Istituto Superiore di SanitB. From that paper I wish to reproduce here a table showing the results on Phlebotomus in the different parts of Tuscany, which is the only area dealt with in the paper of BETTINI etal. I add here that all the Phlebotomus concerned in my paper mentioned above were prepared for study of the pharynx by I. NERI: now they constitute a collection which is preserved in the Laboratorio di Parassitologia of the Istituto Superiore di SanitB. I am, etc., AUGUSTO CORRADETTI Via San Domenico 12, Firenze, Italy
