PAPILIO IDAS. 



SPECIFIC CHARACTER. 



Wings entire brown. An equal marginal row of red fpots both 

 on the upper and underfide. A black fpot in the middle of the 

 anterior wings. 



Papilio Idas : alls integris fufcis, fafcia marginal! utrinque rubro- 

 maculata, anticis macula media nigra. 



This infedl muft not be confounded with the Papilio Idas of 

 Linnaeus. The Linn^an P. Idas is evidently the female of P. Argus, 

 a circumflance unknown to that author, who confiders them as a 

 diftin<51: fpecies from their very diffimilar appearance. In one fex 

 the upper fnrface is brown, and in the other a fine blue ; this is not, 

 however, peculiar to the P. Argus, for feveral of the Papilio tribe 

 known amongft Knglifii colle^lors by the trivial name Blues differ in 

 the fame manner. 



We fufpeft that our Infedl has not been defcribed by any author; 

 it is certainly unnoticed by Fabricius in his lafl: Syftem of Entomo- 

 logy, and the fpecific name Idas omitted. This name is therefore 

 preferred for our Infecl, which feems to approach nearer to the 

 female Argus defcribed by Linnaeus as Idas, than to any other. 

 Found in May.
