As this insect is coustautly dift'ereut from P. phlloxenan, especially in the 

 position of the large white patcli on the hindwings, it represents certainly a distinct 

 species. 



c?. Upperside, hinchvings: the wliite spot between the snbcostal and upper 

 discoidal nervules is often very small or even absent ; on the disc between the lower 

 median veins there is in one example a small reddish white mark above, half-way 

 between the cell and the submarginal lunule ; another specimen has, moreover, a 

 small anal .spot; the geminate spot at the apex of the tail is very small and 

 sometimes obliterated. 



Underside: some specimens have a small white submarginal spot behind the 

 costal margin ; besides the pinkish white anal mark there are mostly some discal 

 spots, often forming a complete macular band which connects the large white patch 

 between the di.scoidal veins with the anal spots ; in one individual the di.scal spot 

 between the upper median and lower discoidal veins is merged together with the 

 corre.sponding submarginal mark. The spots at the apex of the tail are always larger 

 than above. 



? . Varies in a similar way as the male. The hindwings have above always 

 a distinct anal mark, and besides mostly some discal markings, of which that before 

 the upper median nervule is in two of my specimens joined to the submarginal mark. 

 The underside of the abdomen is mostly as black as in P. philoxenus lama Oberth. 



//«?). Cashmere (Kulu ; 7 tj, 2 ?); Kumaon (1 ?); (Darjeeling; 1 ?,;Stoliczka 

 ler/., coll. Felder). 



lly supposed Sikkim specimen is rather larger than those from Kulu. As no 

 specimen of ravaiia has been found in Sikkim more recently, the occurrence of this 

 .species in that country remains still doubtful (see P. latreillei Don.).

Differs from P. rnvana Moore, especially in the absence of the red spot near 

 the apex of the tail, and in the scent-organ of the male, which is blackish brown 

 in ravana and creamy white in nevilli. 



The first white or reddish white submarginal spot on the upperside of the 

 hindwings, standing behind the subcostal nervule, is sometimes absent or greatly 

 reduced ; the large white mark is also variable in size, and so are the three posterior 

 submarginal spots, of which the two last are wanting in a few specimens ; the spot
