Tbe/eina/e has the markings of the wings larger than the male, and mostly of a 

 much paler colour ; the submargiual spots of the hindwings are esjiecially enlarged. 

 The forewings have often some minute linear spots between the outer margin and the 

 submarginal series of rounded markings in both sexes. The anal yellow mark is 

 slightly variable in size.

This Papilio inhabits Sikkim, Assam, Burma, Tonkin, Tenasserim, Sumatra, and 

 Borneo in four subspecies, which gradually run into one another. 



(a): P. slateri Hew. occurs in Northern India ; 



(6): P. sldteri tavoyanus Bntl. in Tenassoriin, L'pper Burma, tlie t^han t^tates, 

 and Upper Tonkin : 



(c): P. slateri jjersea Nicev. in Sumatra ; and 



(d) : P. slateri heioitscmi Westw. in Borneo. 



The pale bluish streaks of the forewings are long and exteriorly sharply cut oti' 

 in P. slaten; in typical tavoyanus these streaks are represented by some small 

 indistinct spots and patches ; in intermediate e.xamples the spots become larger, 

 better defined, and assume the form of the streaks of slateri. In the Sumatran race ^ 

 ( perses Nicdv.) the forewings have no blue, but in an aberration described liy I)e 

 Niceville as P. petra the streaks of slateri reappear, but are white, not bluish ; the 

 exterior region of the forewing o{ jjerses and its aberration is of a lighter brown colour 

 than the base, just as is the case in P. slateri tavoyanus, whereas in P. slateri 

 hevntsoni the forewings are of a uniform brownish black colour. 



In the shape of the forewings there is considerable variation; hewitsoni has the 

 most rounded outer margin ; in slateri that margin is sometimes as convex as in 

 heiL'itsoni, but often it is rather strongly concave. 



The hindwings are above of almost uniform colour in typical P. slateri and 

 Itewitsoni; in tavoyanus and perses they have a submarginal white band, which 

 consists of conical markings standing in pairs between the nervules. Now in slateri 

 these markings are .'sometimes slightly indicated; in other specimens they are clearly 

 visible, but much shaded with brown, and in a female from the Khasia Hills they are
