In the Mediterranean countries the Mediterranean fruit-fly {Ceratitis capitata Wied.) was first recorded from Spain in 1842, from Algeria in 1859, from southern Italy in 1870, from Sicily in 1882, from Tunis in 1885, from Malta in 1893, from Egypt in 1904, and from France in This chronology, however, does not necessarily represent the spread of the insect, for it may have occurred in some of the countries long before any published record appears. In addition to the coun- tries enumerated it is also said to occur in Asiatic Turkey. In the Mediterranean vicinity it is recorded from the Azores, Madeira, and Cape Verde Islands. The writer has taken this insect at Valencia i This paper is of immediate value on account of the important information it contains bearing on the subject of the need of regulating the entry of citrus and other fruits imported from Mediterranean countries to prevent the entry of the Mediterranean fruit fly into the United States. The investigations embodied in this paper were made by Prof. Quayle during the summer of 1913 as a collaborator of the Federal Horti- cultural Board of this Department. Prof. Quayle is an expert on citrus insects and has previously made important studies in this field in California in connection with the State experiment station. Advantage was taken of the fact that he was proposing to use his sabbatical year to make a world-wide survey of citrus insects to commission him to make a much-needed preliminary survey of the citrus and other fruit insects in Mediterranean countries, more particularly in relation to the export fruit to the United States.
