THE CANADIAN ENTOMOLOGIST. 47 



see that Hubner does net use the names of the 13 secondary divisions of 

 the Papiliones of the Tentamen at all in the Verzeichniss. The species 

 Polymnia, for instance, stands in the former as " Nereis Polymnia ; ' ; in 

 the latter it is Mechanitis Polymnia ; Potamis Iris is changed to Apatura 

 Iris, and so on through the entire list. And only a part of the Stirps of 

 the Tentamen are retained in the Verzeichniss, five of them, namely, all 

 the Gentiles, being changed for others, as Principes to Archontes, &c. 

 Moreover, one Stirpsin addition is given to each Tribe. 



Yet the author of the Sketch, in disregard of Rule 12, has 

 given the names of these 13 secondary divisions of the Tentamen as 

 so many names of genera, crediting them to Hub., 1806. Thus Nereis 

 Hub., 1806; Consul Hub., &c, adding to each the species accompanying 

 it in the Tentamen, with the words " sole species and therefore type." • 

 These names have never been used, and several were dropped by Hubner 

 himself, but the systematist of to-day must reinstate them, as he terms it, 

 as if they had ever had one moment's standing, and claims for them an 

 honest priority over the labors of other men. And not only has Mr. 

 Scudder given a set of names based upon these divisions of the Tenta- 

 men, but a complete set of other names for the equivalent divisions of the 

 Verzeichniss. Thus Hubner, as I have said, changed all the Stirps of the 

 Gentiles, Principes into Archontes, Rustici into Astyci, &c, and we have in 

 the Hist. Sketch a genus Princeps and a genus Archontes ■, a Rusticus and an 

 Astycus, each pair in Hubner standing for precisely the same thing. But 

 apparently to escape the appearance of their duplication, the last set are 

 attributed to " Franck's Catalogue/' a production much subsequent to the 

 Verzeichniss and of which I will speak presently. 



But to return to the Tentamen. In the Hist. Sketch we read " Potamis 

 Hub. Tent., 1806 ; Iris sole species and therefore type. This name never 

 since used must be restored." " See Apatura" Turning over the leaves 

 we find u Apatura Fab." and three species ranged under it, Iris, Bolina 

 and Alimena, and read : " in 1806 Hubner (Tent.) selected Iris as type of 

 Potamis. Consequently Apatura must be restricted to the other two, which are 

 congeneric, and Bolina may be taken as the type. This, however, is not in 

 accordance with subsequent usage (from 1806), as will be seen by the follow- 

 ing^ &c. And then are given a dozen authors, including Hubner himself 

 in the Verzeichniss, nearly every one of whom has employed Iris as the 

 type of Apatura. And Mr. Scudder adds with amusing naivete', "this 

 result is from want of familiarity with Hubner's Tentamen \ "
