About 3000 species of endemic insects are known in the Hawaiian Islands. Apparently a much larger number of endemic insects than have developed in any other group of oceanic islands in the Pacific. There are a good many endemic genera and in many of these a large number of species has developed. Often the geographical isolation has been the important factor in the evolution of species; and in many instances it has been the various food habits that has brought about such great production of species. As examples of genera in Lepidoptera with large number of species are Scotorythra with 30 species; Omiodes with 20; Phlyctaeniawith 25; Hyposmocoma with nearly 200 species. In the Coleoptera some interesting genera are Plagithmysus with 49 species; Rhyncogonus with 25 species; Proterhinus with 150 species. In Homoptera are Ilburnia with about 100 species; and Oliarus with 50 species. In Hymenoptera Odynerus has about 100 species; and Sierola 171 species. Many other similar examples could be given.
