The type specimens of Hymenoptera species described by Frédéric Chevrier deposited in the Muséum d'histoire naturelle de Genève

The Genevan entomologist Frédéric Chevrier (1801-1882) was interested in natural history from an early age and amassed an important collection of Coleoptera which he was forced to sell in 1849 because of financial difficulties. After this he led a quiet life near Nyon in the canton of Vaud (Switzerland), where he began collecting Hymenoptera and published seven articles between 1862 and 1872, describing 35 species as new to science. His collection came to the Muséum d'histoire naturelle de Genève with that of Henri Tournier (1834-1904) in 1904. We present a list of the type specimens of Chevrier's species deposited in the Muséum, along with the current nomenclatural combination and some biographical information.
