INTRODUCTION. 



Ochsenheimer's first family is named Schecken-Falter, Papiliones variegati ; 

 Scheindornraupen, Larvce pseudospinosce ; Schmetterlinge von Europa, vol. i. pp. 



17 to 51. 



This is precisely the character of Fam. L. of the Wien. Verz., p. 178 : and of eleven European 

 species enumerated by Ochsenheimer, seven are found here, viz. P. Phcebe, Maturna, Cynthia. 

 Dyctynna, Cinxia, Trivia, Lucina. This family is now admitted as a genus with the Fabrician 

 name of Melitjea. 



The second family is marked Edel-Falter, Papiliones nobiles ; Halsdornraupen, 

 Larvce collospinosce ; Schmett. v. Eur. i., pp. 52 — 100. 



This constitutes the Fam. K. of the Wien. Verz., p. 176: and of twenty European species 

 enumerated by Ochsenheimer, ten are contained in this catalogue, viz. P. Pandora, Paphia, 

 Adippe, Aglaja, Niobe, Latonia, Euphrosyne, Pales, Dia, and Daphne. This family is now dis- 

 tinguished as a genus with the Fabrician name of Argynnis. 



The third family is marked Eckfluegelige-Falter, Papiliones angulati ; Scharf- 

 dornraupen, Larvce acutosphiosoe ; Schmett. v. Eur. i. pp. 101 — 134. 



It agrees with the Fam. I. of the Wien Verz., p. 174 : and of twelve European species enume- 

 rated by Ochsenheimer, eleven are contained in this catalogue, viz. P. Atalanta, Cardui, lo, 

 Antiopa, Polychloros, Xanthomelas, Vau album, Urticce, C — Album, Prorsa, Levana. This family 

 now constitutes a genus with the Fabrician name of Vanessa. 



The fourth family is named Bandirte-Falter, Papiliones fasciati ; Halbdorn- 

 raupen, Larvce subspinosce ; Schmett. v. Eur. L, pp. 135 — 149. 



It constitutes the Fam. H. of the Wien. Verz., p. 172 : and of five European species enume- 

 rated by Ochsenheimer, four are found in this catalogue, viz. P. Populi, Sybilla, Camilla, Lucilla. 

 This family is distinguished as a genus with the Fabrician name of Limenitis. 



The enumeration of these four families is sufficient to show, that the families of 

 Ochsenheimer and the genera of Fabricius, in this tribe, agree with the families 

 of the Vienna Catalogue, and both may be considered as derived from them. The 

 remaining families of Ochsenheimer's Papilionidas may be traced to the same source, 

 and the comparison will be found highly conducive towards obtaining distinct views of 

 the early merits of this catalogue. In the work of Ochsenheimer, each of the families 

 is preceded by a precise and well-defined descriptive character ; he considered them 

 indeed as genera, although he neglected the opportunity of imposing a name. In 

 the preface we find the following passage. " It has long been wished, and it has 

 also been attempted, to divide the numerous host of diurnal Lepidoptera into several 

 genera ; I therefore entertain the assurance of not venturing too much, when I 

 consider, and treat as a genus, each of the families employed in the sequel." In 

 the fourth volume, which contains a systematic arrangement of genera and species,
