1928 (3rd ed.) Reprint 1989 491 p., 70 figures, 95 coloured plates, hardbound (with worn dust jacket). Library stamps, else good copy. Although it bears the same title as the book by Ter Haar, this book was written by Keer and was based on another German Butterfly book âǘâÇÖGrossschmetterlinge und Raupen Mittel-EuropaâÇÖsâÇÖâÇÖ by Lampert. The text is written to match the Dutch Lepidoptera fauna. A good reprint of this work
