Parnassiana Nova [C. Eisner] — Parnassiana Nova. I-L.

1954-1975 In five volumes, first three bound in half morocco and last two in half cloth. Library stamps and first volume with discoloured spine, else a good set of the first 50 (of 59) papers that Eisner wrote on Parnassia. The German entomologist Curt Eisner (1890-1981) was a specialist on the butterfly subfamily Parnassinae, and started a series of papers that he named Parnassia Nova after the journal of that name (without Nova of course) by the Swedish entomologist Felix Bryk.
