Von Mitis says that this " is most certainly nothing more 

 than an aberration of D. mindanaensis, in which the whole 

 of the marginal spots on the under surface of the hind wings 

 have become white." If this is correct, D. cathara must be 

 a parallel form of D. hyparete ; but, to my mind, there is no 

 certainty in the matter. Both insects are considerably 

 smaller than the red-spotted species, and fall naturally into 

 the D. singhapura group.
