 seventh line can be traced across the wing, which also has dark marginal dashes at 

 the end of tlie veins. The hindwing is paler, with the markings clearer. On the 

 underside the whole of the forewing, except tlie red costal area, is blurred grey, 

 without any pale dusting, while the bands nf (lie hindwing and tlie basal speckling 

 are dark olive-fuscous and very distinct. Thi' pwlpi, shoulders, and ]iatagia are 

 all varied with red scales ; the red face has a dark lino down the midtllc,
