Seven seminal works by the Czech entomologist Franz Xaver Fieber (1807-1872); each containing excellent descriptions and detailed drawings – by the author – of many new or poorly known genera and species. Published in the Abhandlungen der Böhmischen Gesellschaft der Wissenschaften, probably in 1844, as stated in Horn-Schenkling. In the top margin of the first title, a small printed label of "Bibliothèque d'Histoire naturelle de Dr Maurice Royer". Maurice Royer (1878-1942) was a French entomologist and Hemiptera specialist. A few pencilled notes in an old hand; some wear to the board edges; spine cover ends abraded, title with a vertical crease; short tear in one plate margin, a few pages lightly (ink) spotted but generally clean and in a very good condition.
