P. chaon is the Iiidiaii reineseiitative of P. ;ie^.>ftc^((8, and very closely allied to 

 that species ; the distinguishing characters seem to me to be of no great importance, 

 and I shall not be surprised when intermediate examples between chaon and nephelits 

 turn up some day from i^iani. Tenasserini, or the northern parts of the Malay 

 Peninsula. 



The subapical band of the furewiugs of uephelus is here indicated only in the 

 female ; the marginal apical white mark is mostly of the same size as in itephehca, 

 but sometimes obliterated; the submarginal lunules of the hindwings below are of 

 a yellowish buff colour, not white. I must, however, state that in a sjiecimen 

 of P. iiephelus arauus M>ym. these spots are also huffish, though paler than 

 in P. chaon ; in most specimens the submarginal lunules are smaller than in 

 P. nephelus satunuts Guer., often partly obliterated, but sometimes they are large, 

 and, as in saturnus, partly merged together with the marginal spots.

yiy smallest male, from ShiUong, Assam, has the forewing of a length of 43 mm. ; 

 in my largest 'male, from Sikkim, that wing is 65 mm. long. 



Tonkinese and Chinese specimens are unknown to me.

Very constant. The patch of the hindwings is sometimes connected with the 

 abdominal margin by means of a narrow yellowish band. The red streaks in the 

 basal region of the hindwings, below, are very peouliai'. The species has no near 

 relative at present.
