The water mites of the genus Atractides belong to a small subfamily, the Hygrobatince. About ten species have been described by European hydrachnologists for Europe; two of these species have been reported by them also from North America, while one species is described for Madagascar. Three new species are now added to the list for the United States. All of the material, thirty-eight individuals, was found by the author in small lakes in Wisconsin.
