Although specimens with fully developed white bastard-wings 

 are distinct enough from P. mcdaharicus, yet ever}' kind of inter- 

 mediate link is found between the two species, which appear, from 

 the evidence of specimens in the Hume collection, undoubtedly to 

 interbreed on the confines of their ranges,
