PAPILIONID^. 



Yar. dehaani, Felder, " A bianore, Cram., cum quo cl. De Haan colore et signaturis fortasse 

 deceptus confudit, longe diversus et P. maacJcii, Menetr., valde similis, facile tamen digno- 

 scendus lunulis submarginalibus paginae inferioris alarum posticarum a margine multo magis 

 remotis. 



" Ycua et plica interna ramique mediani alarum anticarum maris in P. maaclii valde tomentosi 

 apparent, et maculae tres inferiores tomenti in unam fere connjncta; sunt. Specimen nostrum 

 P. raddei, Brem., ibidem parce tantum tomentosum est." (Felder, I. c.) 



Yar. alliacmon, de rOrza. " Tres-voisin du Manor, dont il n'est peut-etre qu'une modification 

 locale d'un tiers plus petite. II differe de cette espece chinoise en ce que chez le male les 

 trois croissants de la region abdominale sont surmontc's d'une petite lunule violette." {De 

 rOrza, I. c.) 



Yar. japonica, Butler. " Alae anticje subtus late fuscse : posticae caudis \\x spathatis ; supra 

 macula anali minus conspicua ; subtus prope marginem luteo roratte, maculis submarginalibus 

 minus lunulatis, macula anali bis baud distinguenda." {Butler, I. c.) 



This species exhibits considerable variation in the male. Some specimens 

 have very bright green scales thickly powdered over all the wings ; in others 

 the green scales are dull in tone and on the secondaries are eclipsed by the 

 more vivid tint of the blue colour on costal area of these wings. Green scales 

 are sometimes interspersed with the blue ones forming the submarginal 

 lunulcs ; these blue lunules are not always well defined and the lower ones 

 arc sometimes entirely replaced by the reddish colour, which, in other specimens, 

 is sometimes present in a greater or lesser degree, forming an outer edging to 

 one or more of the lunules. The blue colour, usually restricted to the im- 

 mediate vicinity of the ncrvule, is in some specimens diffused over the greater 

 portion of the tail. 



The Japanese summer form of P. bianor, which has been described as 

 dehaani by Felder, differs principally from the type in having the basal half 

 of primaries, on under surface, blacker, more clearly limited outwardly, and 

 the grey of outer lialf of these wings is whiter, broadly bordered exteriorly 

 with black, and forms a tapering band to inner margin. The Japanese spring 

 form \ii japonica^ Butler, wliich, like tlie Chinese spiing f(n'm,is mucli smaller 

 tliaii the type, and exhibits the same differences on the under surface as noted 

 ill the Japanese summer form. Alliacmov, de I'Orza, is also referable to the 

 .Iai)ancse P. hianor, and, as it is said to he a third smaller, probably to the 

 s])riiig brood, japonica, lUitler.
