less transparent ; the white portions of the costal margin in the apical half of the 

 cell are covered with much narrower scales than in P. vui ndarintLS ; the black 'bands 

 of the forewings are broader, especially the marginal and submarginal bands. On 

 the hiiidwings, the subbasal black band is always interrupted behind the median 

 nervure, owing to its being covered with white scales. In the male the abdominal 

 fold, when opened out, shows mucli less black; tlie rudimentary scent-organ at the 

 base of the fold is much whiter, and the scales composing it are obviously longer. 

 Hairs of the front of the head longer. 



While P. mandarinus is variable, its In<lian representative is almost constant 

 in its characters.

The specimen figured by Elmer {I.e.) is tamerlanus Obeith. and not alehiun 

 Gray, and I do not believe that the patria '• Nordchina " which Eimer gives to his 

 alebion (not Gray's) is correct. This mistake in the identification accounts for 

 his considering tamerlanus to be " ein einfacher iilclnoii.'' 



P. alebion and tamerlanus have the discoidal cell to the hindwings much 

 broader, especially so in its apical half, than any other species of the present 

 group. 



The chief characters by which P. alebion and tamerlanus can be distinguished 

 from each other are as follows : — 



The hindwings of P. alebion are much more produced in the caudal region, and 

 are, therefore, much narrower than those of P. lairteiianus ; the anal yellow mark 

 to the hindwings of P. tamerlanus is at least three tinies as broad (transversal ly) 

 as long, and divided (or almo.st so) into two spots by the black lower median nervule, 

 while in P. alebion that mark is abont as long as broad (and therefore much larger 

 than in P. tamerlanus), and not divided into two spots; the po.^tcellular portions of 

 the subbasal and median black lines, which form a very conspicuous angle on both
