Conteúdo: 	The present review includes all the 23 species  in this genud from North America, witch special emphasis on the polymorphism associated with feeding sites. Seventeen species have been redescribed and ilustrated in detail, each with a discussion of their morphological affinities and relationships. Their host and habits  zoogeography are summarized. The three species that have been recently redescribed- C. americana, C. kosztarabi and C. nyssae are also discussed, and the most important morphological characters and the plates prepared by the original authors for each of these three species are given in orden to better utilize the key to the species in North America. As a direct result of this research three new species have been discovered. This publication also includes many new distribution and host records for several species. The five species having typical bark and leaf forms, as well as intermediate forms, are discussed in more detail. A separate chapter deals with polymorphism, including a literature review of the subject. A hypothesis is given on the modes of transfer from the bark form to the leaf and vice versa, that result in different morphs in first or second fenerations. Two keys were preparated one for the genera of the sutribe and another of the determination of the species of Chionaspis in North America
