200 NYMPHALIDJE. 



fore wing, club long, narrow, gradual ; palpi slender, slight, oblique,. 

 3rd joint short ; body stout, robust. Male secondary sex-mark a 

 more or less rounded, thickly packed, large patch of specialized 

 scales on the disc of the hind wing. 



The forms of Discophora are all very closely allied. There is 

 little doubt that the variation in the size and colour of the spots 

 on the fore wing is to some extent due to seasonal dimorphism or 

 polymorphism, and that the number of distinct forms is really 

 very small.
