" Magnus. Alae omnes integerrimae fuscae, anticis fascia fere 

 obsoleta, posticis disco albidis. Ocellus magnus cceruleus, iride 

 flava pupillaque alba alarum posticarum et subtus duo ejusdem 

 coloris, quorum posteriori interdum ocellis minor pupillatus 

 adnatus." 



There is considerable diversity in the pale shade of the fascia 

 of the fore wings, and hence Clerk's figure has a much greater 

 extent of white than Donovan's or Cramer's. Cramer's figure also 

 in his plate 6 exhibits a variety with a minute ocellus, joining to 

 the large discoidal one as described by Fabricius.
