The European families of the Diptera presents an identification key and family descriptions of all 132 families of Diptera (midges, mosquitoes, gnats, true flies) occurring in Europe. It is written by a well-known Dutch specialist, in collaboration with over 30 European dipterists. For the extensive identification key a new combination of important characters is employed, enabling relatively easy identification of families which are aberrant or traditionally considered difficult to identify. Over 600 line drawings are included to illustrate characters and families. Apart from the key, the book includes an extensive chapter on terminology. Information on systematics and the number of genera and species in Europe, a survey of the main characters, a summary of the biology and of the pertaining identification literature is included for all families. Due to its design and content, the book will be of interest to the lay public and the serious amateur alike.

Part VI of Keys to the Insects of the European Part of the USSR covers the suborder Symphyta of the phytophagous Hymenoptera (sawflies and woodwasps), small superfamilies Trigonaloidea, Stephanoidea, Evanioidea of parasitic Apocrita, and the family Paxilommatidae of the superfamily Ichneumonoidea. Identification keys are provided for 18 families, 123 genera and over 900 species which include a large number of economically important species -- the pests of agricultural crops and timber as well as entomophages. A brief outline of morphology and biology, synonymy and geographic distribution is given for each family and genus and the known host-plants are indicated for every species. Three species have been described for the first time and 12 new subgenera have been separated. Bibliography -- 88 citations; 217 illustrations.

The most complete reference work on mosquitoes ever produced, Mosquitoes of the World is an unmatched resource for entomologists, public health professionals, epidemiologists, and reference libraries.
