Käferbuch : allgemeine und specielle Naturgeschichte der Käfer Europas : nebst der Anweisung sie zu sammeln und aufzubewahren
Käferbuch is a German natural history guide to European beetles by Carl Gustav Calwer, published in Stuttgart by Krais & Hoffmann in 1858 for collectors and naturalists. Its pictures are numbered, hand-coloured, dorsal views of single beetles on plain cream paper, with precise legs, antennae and sheen on the wing cases, useful to a designer wanting scientific specimen plates.
