Written by the French entomologist René Martin (1846-1925). Part of a larger series, initiated and financially supported by the Belgian entomologist and father of modern odonatology, Baron Michel Edmond de Selys Longchamps (1813-1900). This is the only part dealing with the dragonfly family Corduliidae, or emeralds. The illustrations are truly excellent. Several species are described as new. According to Wascher and Dupont, "Selys" shaped the classification of Odonata and described over 700 species, established 134 valid genera within the Odonata. "Importantly, his influence in Odonate studies reached beyond his death. The millions invested in the huge project 'Collections zoologiques Selys Longchamps' made it possible for a next generation within the Odonate community to travel to diverse collections and publish in the spirit of Selys. There are few animal taxa, and fewer groups of insects, whose behaviour and ecology are well enough documented to permit the integrated, taxon-focused treatment attempted in this book. All these facts put the taxonomy of the group on a solid footing and provided the base to make Odonata one the best studied animal groups known" (Wascher and Dupont). As indicated by the title, this work was largely based on Selys's magnificent collection. In 1909 a four-page supplement (pp. 99-102) was published. It is included. Provenance: Inscribed Erich Schmidt in the top margin of the front wrapper, and in the top margin of the first Addenda leaf. Erich Walther Schmidt (1890-1969) was a German entomologist specialized in Odonata. A few annotations, including a drawing (probably by Schmidt) in light pencil, otherwise a mint copy. Very rare. We found no auction records whatsoever. Wascher, M. T. and H. J. Dupont (2013) Life and work of Michel Edmond de Selys Longchamps (1813-1900), the founder of Odonatology.
