NOMENCLATURE OF LEPIDOPTERA. 287 



einem Quartblatte abgedruckt herausgegeben,' &c. This can only 

 mean that the Tetitamen was published on a quarto sheet of 

 paper by Hiibner. 



Now as to date — Sir G. Hampson in his opinion, No. 3," [= Reply 

 25] "seems to doubt that Hiibner refers to the Tentaincn in the preface 

 to the Verzeichniss. Let Hiibner speak for himself: — Verz. bek. 

 Schin. 3 (18 16) 'Die Grundlage dieses Entwurfes habe ich sogleich, 

 unter dem Titel : Tentamen dcterminatioiiis, digcstionis atqiic deno- 

 minationis siugularimn stirpiiun Lcpidoptero7'iun bekannt gemacht, 

 damit sie von Verstandigen, bevor ich sie annahme, gepriift und 

 beurtheilt werden mochte.' Compare the words italicised with the 

 title of the Tentamen : ' Tentamen determinationis digestionis atqiie 

 denominationis singularium stirpium Lepidopteroriim, peritis ad in- 

 spiciendum et dijudicandum communicatum, a Jacobo Hiibner.' 



The words in italics are absolutely the same as those quoted 

 in the preface to the Verzeichniss, and it is impossible to imagine 

 that they were used in reference to any other work than the 

 Tetitamen. This being accepted as a fact it is not difficult to 

 arrive at the date of publication of the Tentamen. In the 

 preface to the Verzeichniss (p. 3), it is expressly stated that 

 Hiibner drew up the Tentamen ' vor zehn Jahren ' for his own 

 purposes and immediately made it known. This preface was 

 written in September 18 16, therefore 18 16— 10= 1806 (the approxi- 

 mate date of thtTentameji). 



Zeller writing to W. H. Edwards, 23 June 1876, said: 'The 

 Tentamen was printed not in 1806, but in 1805' [vide Ca?i.Ent.Vlll. 

 160 (1876)], but no reasons were given for this emphatic assertion. 



To recapitulate, Ochsenheimer informs us that the Toitamen 

 wdiS pnblished before 18 10, Hiibner indicates the date of publication 

 as 1806, while Zeller says that it was printed in 1805. 



The fact that Glancopis for phegea is common to the Tetitamen 

 and to Fabricius, 1808, proves nothing. Fabricius and Hiibner 

 corresponded and either author may have used the name in MS. 

 before the publication of either work. 



So far I have only dealt with the question of publication and 

 the acceptance of the Tentamen by Ochsenheimer, there now 

 remains the question whether the Tentamen genera can be accepted 

 as valid from the standpoint of a modern zoologist. 



The British Association Committee laid down two essential 

 points as necessary before any zoological term could acquire the 

 right to recognition in the following words (pp. lO-ii): 



'Two things are necessary before a zoological term can acquire 

 any authority, viz. : definition and publication! 



It has I think been proved that the essentials of publication 

 were complied with, for Sir George Hampson's contention that 

 Hiibner's works were issued at irregular intervals and were not 

 published until they were published by Geyer cannot be taken 

 seriously. All works issued to subscribers have after a time a
