Burgeff, H. & F. Bryk — Lepidopterorum catalogus: Zygaenidae I and II (complete).

1926-1936 Two parts in two. 332 p, paperbound (original uniform printed covers). These are parts 33 and 71 of the series, and containing separate title pages, and in part II a combined title page an index for both. It is unclear why Hans Burgeff (1883-1976) abandonned the project. Stamped on the front wrappers is the text "Verlag Gustav Feller". It is unclear if Feller took over Junk stock, or simply is a redistributor. Uncut. Back wrapper of part 71 missing (blank wrapper, no loss of information), otherwise a good clean set.
