802. PANTOPORIA. 

 1816. Hiibn., Verz. 44: Phaerusa, Nefte, Hordonia, Dorcas (Mar- 



dania). 

 Hordonia may be taken as the type. 



803. PAPHIA.* 



1807. Fabr., 111. Mag. vi. 282 : I. Jason (Jasius), Pollux ; II. Va- 

 ranes, Morvus (Laertes), Chorina^us; III. Medon, As- 

 tyanax (Ursula) ; IV. Odius (Orion), Isidora (Itys), 

 Acontius (Antiochus). 



1829. Meig., Eur. Schmett. i. 95 : uses it for Jason (Jasius) only, 

 which therefore becomes type, as stated by Crotch (Cist. 

 Ent. i. 66). 



It has subsequently been used in same sense by many naturalists, 

 but is preoccupied in Mollusks (Lam. 1801). See Charaxes and Jasia. 



804. PAPILIO. 



[1735. Linn., Syst. Nat. ed. i. (Fee's Reprint, p. 76): no species mentioned; 

 intended to include all Lepidoptera, divided into three groups, of 

 which butterflies form the first. 



1736. Ib., Acta Upsal. iv. 117 : species mentioned (without names) are, as given 

 by Hagen : * rhamni, brassiere, rapae, napi, erataagi, Apollo, Antiopa, 

 polychloros, urticse, c. album, lo. 



1740. Ib., Syst. Nat. ed. ii. 60 : no species mentioned ; divided into several 

 groups by the structure of the antennae and mouth parts, those 

 "pedibus 4," i.e. Nymphales, placed first. Essentially the same 

 arrangement occurs in the third, fourth, and fifth editions. 

 1746. Ib., Faun. Suec. ed. i. 232 : the butterflies are divided into two groups, 

 according as they have four (serviceable) or six legs. Species occur 

 again without names, but numbered from 772 to 807 inclusive ; 772 

 was afterwards named Antiopa. 



1748. Ib., Syst. Nat. ed. vi. 63 : species are introduced for the first time in a 

 general work, but still unnamed. Sixteen butterflies only are men- 

 tioned, all of them before treated of in the Fauna Suecica. Antiopa 

 heads the list. The arrangement of the seventh and ninth edition 

 is identical ; the eighth edition contains no animals. 

 I have introduced the foregoing only for its historic interest. The 

 reader will find fuller details in papers by Dr. Hagen and myself in the 

 Canadian Entomologist, vol. vi. pp. 143-145, 163-166. In this matter I 

 hold to the views of Agassiz, who lays down as a maxim for genera: 

 Cum binominalis nomenclatures Linnceus sit auctor, ilia de prioritatu lex ad 

 anteriorum auctorum opera non est retorquenda^ I do not therefore deem 

 even Linne's action (previous to 1758, when binomial nomenclature was 

 founded) to have had any binding force; yet, in view of the opinions I 

 expressed in my Systematic Revision (p. 16), without examination of
