figured in the Zutrage were new to Science. The Zutrage was one of the few works of 
Hiibner to which complete letterpress was issued, The introduction deals with nomenclature, 
and other generalities, and the letterpress states the locality, sex, collector, and affinities 
of the specimen figured. It rarely, however, contains information of permanent value, and 
we have therefore replaced it by alphabetical and systematic Indices, only quoting one or two 
specimens to show its character, In the alphabetical Index the numbers in the systematic 
Index are quoted, so that-every species can be referred to without difficulty. 
The following are the contents of the five parts of the Zutrage. 
Erster Hundert (dated 1818), 32 pages (of which 2 are Title and Introduction) and 
8 pages of Index, giving separate lists of the species figured, and their generic and specific 
names, and similar lists of the allied species with which they are compared. 
Zweyter Hundert (dated 1823). Letterpress similar. 
Drittes Hundert (dated 1825), 40 pages, of which 2 are Title and 4 Introduction; and 
8 pages of Indices. 
Vierter Hundert (by Carl Geyer) (dated 1832); 48 pages of which 2 are Title, 
4 Introduction, and 6 Indices. 
Finftes Hundert (by Carl Geyer) (dated 1837); 52 pages including 2 Title, 2 Intro- 
duction, and 6 Indices.
