Two new species of Ixodes are described herewith. Both have been recognized for the past ten years as differing in certain respects from known species. Published descriptions of them, however, have been withheld pending a fuller knowledge of their distribution and further studies on the stability or certain differences between them and allied species. The acquisition of further study material having shown that differences are constant, the writer now feels justified in erecting two new species, thus differentiating these ticks from allied species with which they have been confused.
