48 *HE CANADIAN ENTOMOLOGIST. 



Beyond a question, the Tentamen, though historically interesting, or 

 as a curious fossil, has not the least value as an authority for nomencla- 

 ture, and these 13 genera set up by Mr. Scudder must come down. 



The other Phalanxes of the Tentamen, and which cover about 80 per 

 cent, of that sheet, relate to the Heterocera, and I shall not say more of 

 them at present than that they one and all are subject to the same fatal 

 objection with the Papiliones ; and any system of arrangement based 

 upon these divisions is worthless. 



2. In the year 1825, a certain collection ot Lepidoptera owned by 

 the late M. Franck was offered for sale by his widow, and Hubner was 

 employed to draw up a sale catalogue, a copy of which, from the Mus. 

 Comp. Zool. Camb., I have examined. It is entitled ''Catalogue de feu 

 M. Franck, cette collection est en vente chez Mme. Ve. Franck, a 

 Strasbourg." Near the end is a classified list of all the species 

 embraced in it, divided according to the Stirps of the Verzeichniss, 

 merely the names and the habitat being given, as Archon Poly damns 

 L. Brazil, Astycus Proteus L. Surinam. Now these names are not 

 generic names in this Catalogue unless the Stirps names in the Ver- 

 zeichniss are also generic names. They, as well as the Stirps names, are 

 given to what modern systematists call a Family or sometimes a Sub- 

 Family. For example, Andropodum in this Catalogue embraces 44 

 species, including all the modern genera of the Family or Sub-Family 

 Pieridse, as Pieris, Anthocharis, Colias, Tcrias, Callidryas, Goneptcryx ; and 

 it is identical with the Stirps Andropodum of the Verzeichniss. Under 

 Archon, which is equivalent to Papilionidae, stand Papilio, Leptalis, Thais, 

 Parnassius, and so on. It is plain, therefore, that these names are in no 

 sense names of genera. And yet Mr. Scudder has set up several of them 

 as names of genera, being, as I have mentioned before, all those which 

 Hubner substituted in the Verzeichniss for the names of the Tentamen. 

 But instead of taking them directly from the Verzeichniss, he seems to 

 have adopted a round-about method. On page 93 Hist. Sketch, he says : 

 " Only those names !? (of genera) "are introduced which are connected 

 with the binomial nomenclature founded by Linne ; for this reason the 

 trinomials of Hubner " (such as Oreas nubila JVorina, Andropodum fugax 

 Palaeno, etc., astonishing appellations used in the iconographic works of 

 Hubner) " and other writers have been totally disregarded. All or nearly 

 all the trinomials of Hubner are actually used by him in some -work or other, 

 in the Tentamen or Franck' s Catalogue, with a binomial application, and in 

 those cases they arc here introduced, but only dating from the time at which
