In 1886, Professor Herbert Osborn and Professor L. M. Underwood published, in the "Canadian Entomologist," a preliminary list of the Acarina of North America. This list included 99 species in 28 genera. In 1907, Nathan Banks published his "Catalog of the Acarina, or Mites, of the United States," which includes about 450 species in 133 genera. This number probably represents less than one-third of our mite population.
