Adalbert Seitz, full name Friedrich Joseph Adalbert Seitz, (24 February 1860 in Mainz – 5 March 1938 in Darmstadt) was a German entomologist who specialised in Lepidoptera.
Early in his career he studied butterflies in Brazil, and was later a director of the Frankfurt Zoo.
He was the editor of Die Gross-Schmetterlinge der Erde (The Macrolepidoptera of the World).
This is a sixteen-volume work with four supplements published in German, French, and English.
For details see Griffin, F.
J.
(1936).
The first four volumes describe the Palaearctic fauna and volumes 5–16 describe the exotic Fauna (Volumes 1–4, Palaearctic Fauna, with 4 supplements; Volumes 5–8, American Fauna; Volumes 9–12, Indo-Australian Fauna; Volumes 13–16, African Fauna).
The coloured plates were made by 10–14 colour lithography.
Seitz planned to finish the whole work in 1912, but this proved to be quite unrealistic and publication stopped in 1954.
