Not published, no date [but after 1936; probably ca. 1950]. Large 8vo (24.0 x 16.1 cm). 161 ruled pages with mounted strips with printed text. Mid-20th century black blind cloth over marbled boards.

A unique item from the collection of the malacologist, ecologist and entomologist Herbert Ant (1931-2010). It is essentially a long list of butterfly genera and species (numbered 259-402) with three columns: name, male, female, with occasional price-indications, for instance: Valeria Stph. oleagina F. Male 1.20, female 1.50. This is followed by an alphabetical index of 18 pp. These printed strips are derived from the Staudinger Preis Liste palaearktischer Lepidopteren based on Otto Bang-Haas's Catalogus lepidopterorum regionis palaearcticae, and published by Staudinger and Bang-Haas in Dresden from 1937 onwards. Additional notes have been made in pencil on the ruled paper, giving the impression that the author may have bought - or perhaps sold - the specimens indicated, or - more likely - noted their occurrence. Dr. Ant's tiny stamp on the front free endpaper recto, and bottom edge. Otherwise very good, clean.
