 grey spot, often absent. Hindwing with the costa broadly black, narrowing round 

 the apex, and continued narrowly round the outer margin to the anal angle. Cilia of 

 both wings brown. Underside dull red. Forewing with the whole space below the 

 sub-costal vein black, the red space being confined to the costa narrowly and to the 

 apex broadly. Hindwing with a broad straight whitish streak, from the base, through
