Tableaux analytiques des coléoptères de la faune Franco-Rhénane (France, Hollande, Belgique, Région rhénane, Valais). Famille XXXIII Cryptophagidae.

Toulouse, J. Bonnet [for Miscellanea Entomologica], 1929. 8vo (24.0 x 15.8 cm). 197 pp., 141 text engravings. Near contemporary half calf over marbled boards. Spine with four raised, gilt-chained bands and gilt title. Marbled endpapers. A rare work by the French entomologist and parasitologist Louis Falcoz (1870-1938) separately published from the "Faune Franco-Rhenane" series (Revue Miscellanea Entomologica volumers 31 and 32). This work deals with the silken fungus beetles. "[B]oth adults and larvae appear to feed exclusively on fungi although in a wide variety of habitats and situations, such as rotting wood and shed animal fur and feathers. Around 600 species have been described and are placed in about 60 genera" (Wikipedia). Falcoz's work contains descriptions and illustrations of whole animals and taxonomically important parts of adult specimens. Included are descriptions of the general characters, tables to the genera, subgenera and species, a bibliography and index. A very good, clean, and well-bound copy.
