America has a great number of offshore islands, particularly in the fjord region of southern Chile, but there are also other truly oceanic islands lying far from the mainland and composed entirely of volcanic material.In this paper I shall attempt to present a general account of the composition of the terrestrial faunas of the oceanic islands, and to show their relationships with the faunas of other regions, before discussing the origin and possible antiquity of their older elements.Easter Island, Juan Fernandez, Desventuradas, and the Galapagos will be considered here, but the isolated Salay Gomez and the Cocos and Malpelo islands will not be dealt with because they are not sufficiently well known.In table 1 is shown the location of the islands to be considered, together with other basic data (see also fig. 1). Easter IslandThis remote island has a low and uniform topography relieved by a few craters which have no human record of volcanic activity.It is fairly arid, having no streams, lakes, or swampland, and showing surface water only in the depths of three of the craters.Its climate is warm-temperate, with its rainfall evenly distributed through the year (Cfa in the Koppen-Geiger classification).It is the only island of the four with a native human population.Man and his domestic animals, particularly sheep, have been largely responsible for the impoverishment of the flora and for this reason Easter Island has only 31 species of flowering plants.Skottsberg, in 1928, was therefore able to say

on a field trip in the hills north-east of Oakland, Califfornia, with his parents and his brother .^lan when he discovered the first larva of the genus Callomyia to be recorded for the New World. In fact, only three previous collections of the immature stages of callomyias are mentioned in the literature. All three records are from Europe. They are summarized by Lundbeck( 1927) as follows: one collection bySchnabl o{ Callomyia amoena reared from an unidentified fungus growing on /I /wws, a collection by deMeijere in July of the larvae of the same fly in an unidentified fungus growing on a fallen tree trunk, and the collection in September by himself of a larva of an undetermined species of Callomyia from a species of Corticium.
