4. Zutraege zur Sam'l. Exot. Schmett. 



5. Verzeichniss bekannter Schmetterlinge.

 Of these, No. 3, begun 1806, was continued to 1833 by Geyer. 

 Vol. 1, 413 pi., title, Index, and 12 pages text. 



Vol. 2, 225 pi., title, Index. 



Vol. 3, 21 pi. 



Of No. 4, begun 181 8, continued to 1833, were published Vols. 1, 2, 

 3 and 34 pi. of iv., but without text. No mention is made in Geyers list 

 of the Tentamen. 



In Thon's Entom. Archiv., Jena, July, 1827, Vol. r, p. 28 — 30, Geyer 

 has given a biographical sketch of Hiibner, in which he states that 

 Hiibner was first a designer in a cotton factory near the Moldavian 

 frontier ; was entirely self-taught, but studied the Lepidoptera diligently. 

 That Geyer became acquainted with him and worked with him from 18 18 

 onward, and he continues thus : " but as in the beginning Hiibner felt the 

 necessity of a natural system to be able to give accurately the limits of 

 all groups of the Lepidoptera, he printed a provisional sketch after the 

 principles of Linne', Fabricius and Schiffermueller, on a quarto sheet, which 

 later 7c>as enlarged and published with the title Verzeichniss bckanier Schmet- 

 terlinge, 1 8 1 6, 8vo. What he believed erroneous in this work (Verzeichniss) 

 he tried to amend in his Lepid. Zutraege'' published 1820. Geyer then 

 gives a list of Hiibners works, same as that given in the Rev. Ent. before 

 cited, and makes no mention therein of the Tentamen. Mr. Scudder, 

 Hist. Sketch, p. 98, speaking of the Tentamen, says : " It is also included 

 by Geyer in his list of Hiibner's works." What Geyer says we have seen. 

 The Tentamen is included in neither of his lists of Hiibner's works, but 

 apart from the list, in Thon's Archiv., a " provisional sketch," not even 

 specified as the Tentamen, is stated to have been made, which later was 

 published as the Verzeichniss. The very word used by both Geyer and 

 Hiibner — a sketch — implies incompleteness, and means a rough draft, an 

 outline, and cannot possibly be construed to mean a "work," which is a 

 completed structure, and in this case a completed book. Dr. Hagen 

 calls my attention to the fact that Geyer's words, as well as Hiibners own 

 in the Preface to the Verz., (er machte bekannt.) to-day mean published, 

 but that formerly they were applied to any printed slip, and as used by 

 Hiibner and Geyer are equivalent to " printed, " as I have translated 

 them. The difference between printing and publishing I need not dilate 

 upon,
