25. Hampson (Sir G. F.). 12 Sept. 1896. 



" That the genera of Hlibner's Tentanien be excluded for the 

 following reasons : 



That it has no possible claims to be considered a scientific 

 work or more than a tentative list of names. 



That its genera are entirely undefined and therefore excluded 

 by the British Association rules. 



That there is no evidence it has ever been published and that if 

 published no even approximate date can be assigned to it. The 

 first mention of the Tentamen known to me is by Ochsenheimer in 

 the preface to his volume IV. (writing in 18 16). He gives its full 

 title and says that it was distributed by Hiibner and that he re- 

 ceived it long after the publication of his 3rd vol. in 18 10. 



We know from Geyer's account of Hiibner in Thon's Entom. 

 Archiv, i. 2 p. 28, 1827, that Hubner's method was to print off a 

 few sheets of his various works and send them off to his correspond- 

 ents whenever it suited him and that his works were never regularly 

 published till Geyer issued them after Hubner's death, so that this 

 statement accords with what we know from other sources and the 

 passage was thus interpreted by Hagen who assigns to the Tentanien 

 the date 'before 18 16, possibly before 18 10' quoting the passage in 

 Ochsenheimer. 



In the preface to the VerzeicJiniss dated 18 16 Hiibner says that 

 he attempted a system of classification ten years before and im- 

 mediately made it known. This may refer to the Tentanien but 

 cannot be clearly shown to do so and in opposition to the theory 

 that the Tentanien was distributed in 1806 we have the fact that it 

 includes the Fabrician genus Glaucopis published in 1807."

"The genera of Hiibner's Tentanien are all recognisable as the 

 type is cited in each instance — they are more satisfactory than any 

 genera in the Lepidoptera which had preceded them. They were 

 adopted by Ochsenheimer in 18 16 (vide ScJini. Enr. IV. p. viii), who 

 regretted that he had not been able to employ any of the Tentanien 

 names in his 3rd vol. (18 10), as at that time he had not seen a copy. 

 Ochsenheimer moreover writes 'Herr Hiibner hat unter dem Titel 

 Tentamen ...den Entwurf eines Systems der Schmetterlinge auf
