A thorough update of Arnett's The Beetles of the United States, American Beetles, Volumes I and II cover the genera of beetles that occur in Alaska, Canada, and the contiguous United States. Built on the foundation of the original work and almost completely rewritten with contributions from more than 60 coleopterists, these volumes describe each fa

This publication provides a comprehensive review of the nomenclature and distribution of the Geadephaga of America, north of Mexico. Overall 2439 valid species-group taxa in 208 genera are catalogued along with their synonyms. Besides the usual information pertaining to author(s), date and page of publication, the type locality, location of name-bearing type, first reference establishing each synonym, and etymology for many patronymic names are provided for species-group names. Genus-group names are listed with the author(s), year of publication, page citation, type species with manner of fixation and etymology for most. The geographical distributions of all species-group taxa are briefly summarized and their state and province records are indicated. About 2500 references are listed with publication dates for many in order to assess priority of names.Several new nomenclatural acts are introduced including one new genus-group taxon, one new replacement name, three changes in precedence, five new genus-group synonymies, 65 new species-group synonymies, one new species-group status, and 12 new combinations.The work includes also a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of North American fossil Geadephaga, a list of North American Geadephaga larvae described or illustrated, a list of species described from specimens mislabeled as from North America, and a list of unavailable names listed from North America.

Along the San Marcos River, in and surrounding Palmetto State Park in south central Texas, lie two square miles of relict ecosystem named the Ottine Wetlands. This area of swamps, marshes, and ponds is especially notable for its geographic isolation from other wetlands in southeastern Texas and for its fascinating intermixture of eastern North American plants and animals and western flora and fauna. The scientific importance of the Ottine Wetlands in the surrounding, relatively dry region was first recognized as early as 1928, yet the swamps and marshes have not been thoroughly studied. This is the first examination of the invertebrates--insects, crustaceans, molluscs, and others--that depend directly or indirectly on the abundant moisture of the wetlands. With nearly 290 full-color illustrations, this book describes and illustrates 241 species of flies, beetles, grasshoppers, wasps, ants, bugs, spiders, scorpions, snails, crustaceans, and millipedes that inhabit the Ottine waters, wetlands, and woodlands. In a brief introduction the authors describe the geological formation of the region and discuss the plant life of the area. They also provide a description of Palmetto State Park, with its easily accessed hiking and nature trails. Following the species descriptions, the book concludes with a glossary and a thorough bibliography of other relevant works on invertebrates. Scientifically thorough, yet readable, this book will appeal to nature lovers of all kinds.
