PAPILIOKID^. 



ground-colour paler and the red streak in discoidal cell of primaries broader and darker. 

 Secondaries have a short broad tail, the anal ocellus is larger, and there is a submarginal 

 series of red lunules and a marginal series of red spots ; beyond the cell there is a pale cloud. 

 Under surface as in the male, but the red submarginal markings are broader, those towards 

 anal angle forming complete oval ocelli ; the pale cloud on disc is more conspicuous than 

 above. 



In Chinese specimens there is always a broad red streak at the base of 

 discoidal cell of primaries ; the anal ocellus is well defined, and in some 

 specimens the outer angle of primaries is suflEused with {^reyish scales. On 

 the under surface of secondaries there is sometimes a complete series of red 

 submarginal lunules and usually a bluish cloud at outer angle. In one 

 example there are three red spots on outer margin and in the first median 

 interspace, remnants of the complete ocellus seen in the female. 



This species does not appear to be common in China. I have only 

 received it from Chang-yang and Ichang, Central China, and from Chia-ting-fu 

 in "Western China. The only female that I have was taken at the last-named 

 locality. 



Refemng to the occurrence of P. rhetenor in Sikkim, Mr. Elwes says : — 

 " Found not uncommonly in the lower valleys, and up to 5000 or 6000 feet, 

 from April to October. Two forms of the male exist, which I am not able to 

 separate except by the colour of the hind margin of the fore Aving, Avhich in 

 one form is more or less overlaid with grey or white scales close to the angle. 

 There is also some variation in the white lunules which are present at the 

 abdominal angle of the hind wing, and in some specimens show more or less 

 on the upper surface. The female form described as icarius is, Avithout doubt, 

 the female of this species. It is rare in Sikkim." {Elwes, Trans. Ent. Soc. 

 Lond. 1888, p. 428.)

Male Ground-colour of !ill the wings black. Primaries and anteiior portion of socondarios ihiclvly 

 Bpriiikled with whitish scales on each side of the nc'rvures and nervules, whicli gives the 

 iiisnct a groy and streaked appearance, roslorior portion of secondaries black with a bluish 

 tinge, ornamented with five deep red crcscent-shapcd marks and an ocellus; the latter is 

 bordered with wliite on its external edge, and is situated at the anal angle. Along tlie outer 

 margin arc four sniall red marks, bordered externally with wiiitc, that situated between the 

 extremities of the llrst ami second median nervules being niucli the largest. Under surface:
