158 Mr. O. E, Janson's Notes on 



at the apical angle, tails black, tipped with white, margin 

 between the tail and anal angle slightly eniarginate and edged 

 with black ; beneath brownish-ochreoiis ; primaries with a 

 narrow brown streak at the end of the cell, and a transverse 

 brown band (almost divided into spots by the nervnres) midway 

 between it and the apex, extending from the costa almost to the 

 inner margin, where it becomes narrow and of a darker brown ; 

 secondaries with a brown streak at the end of the cell, and a 

 fine transverse white line beyond the middle, divided by the 

 nervnres, and edged with black on its inner side, commencing 

 at the costa, tnrned inwards posteriorly, and ending just above 

 the anal angle, which is orange-red and the lobe black, Ex- 

 2)anse of wings 16-22 lines. 



Allied to T. liiteu, Hew., but it is of a darker orange above, 

 without the black spots on secondaries, has more elongate wings, 

 and is very differently marked on the underside. 



A. few specimens of this very distinct and interesting species 

 were found by Mr. Jonas flying about a chesnut tree near the 

 River Yokawa, at the foot of Assamayama. 



Papilio iiiucilentus, u. sjj. 



Allied to F. demetrms, Cram., but with all the wings narrower 

 and much more elongated ; primaries above dusky black, the 

 black streaks between the nervnres very narrow ; secondaries 

 Avith the outer margin strongly notched, the tails long and nar- 

 row, black, costa pale yellow, four small indistinct spots along 

 the outer margin, and a broad ring on the abdominal margin 

 dull red ; beneath the primaries are paler than deiitetrms and 

 somewhat shining ; secondaries with four luniilar s])ots along 

 the outer margin, an interrupted ring on the abdominal margin, 

 and a sj^ot near the anal angle pale red. Expanse of wings 3| — 

 4^ inches. 



The very long slender wings are sufficient to distinguish this 

 species at once from P. dcmetiius, Cram., the only species which 

 resemble it in other respects ; it appears to be confined to the 

 mountains, and has been taken by Messrs. Pryer and Jonas on 

 Oyama. 



Papilio alcinous, Klug. 



Mr. Murray has erroneously referred the female of this species 

 to P. menchis, Feld., both sexes of which are figured by Gray 

 as a variety of alcinous, but 1 have not seen it from Japan.
