from Nikko, Central Japan. 139 



Papilio niccomcolenSj sp. n. 



Very near to P. Jielenus^ but constantly differing in the 

 creamy-yellow patch of secondaries being carried below the 

 radial vein in the form of a large squamose spot, and in the 

 submarginal lunules on the under surface of the same wings 

 being far more arcuate. Expanse of wings 5 inches 3 lines. 



Papilio tractipemiis, sp. n. 



S . Intermediate in size between P. macilentus and P. de- 

 metrius; similar to the latter, from which it differs in its 

 greater size, its more elongated Avings, longer and broader 

 tails, also in the greyer tints of the primaries, upon which the 

 black outer border appears more prominently ; below the pri- 

 maries are distinctly paler and greyer, the markings upon the 

 secondaries are brighter in colour, redder, and there is an 

 abbreviated additional red fasciole, bounded below by an 

 arcuate streak of blue scales, across the first median interspace. 

 Expanse of wings 5 inches 2 lines. 



? . This is the P. demetrius of Gray (nee Cramer) ; but 

 when fresh this sex is nearly as dark as the male, although 

 browner in tint, and with two ocellated and several submar- 

 ginal lunate red markings on the upper surface of the secon- 

 daries : as usual, it is broader in wing than the male, and the 

 tails are shorter. Expanse of wings 5 inches. 



A tolerably common form, which may possibly prove to 

 be a seasonal variety of P. macilentus ; but until this species 

 can be reared, it must necessarily be separated as a distinct 

 species. The examples of P. macilentus taken by Mr. Maries 

 are much worn. 



Papilio spatJiatuSj sp. n. 



Possibly a seasonal form of P. alcinous ; the latter species, 

 however, was not obtained in Niphon by Mr. Maries ; he 

 obtained shattered males and a single fine female in Yesso ; 

 it is therefore more probable that this is a local representative 

 of P. alcinous. It differs in its considerably greater size, 

 much longer and more spatulate tails, in the heavier black 

 borders and veins on the female, in the much obscured red 

 submarginal lunules on the upper surface of the male secon- 

 daries, and the broader and dingier submarginal curved spots 

 on the female secondaries. Expanse of wings, ^ 4 inches 

 1 line, ? 4 inches 10 lines. 



This is a commoner species than P. alcinous^ which (owing 

 to the fact that Klug erroneously figures its female as that sex 

 of his species) it generally represents in collections. P. alci- 

 nous ? agrees with the male in size and form.
