The State of Washington is remarkable for the possession of two very different fauneæ: that of the damp coast region, and that of the inland plains and valleys.* The bees of the coast region have become fairly well known through the collections of Professor T. Kincaid and others, but the inland bee-fauna has as yet yielded to science only a fraction of its riches.
