 band is broad on the costa, outer edge slightly incurved to vein 4, out- 

 wards to 2 and inwards to distal margin ; inner edge curved sharply 

 distad below vein 2 ; the outer edge passes through the cell near the 

 end and cuts veins 2 and 3, the inner edge passes through middle of 

 cell and cuts vein 2 and the submedian. Five small subapical spots of 

 greenish-blue, formed by loosely placed scales. Hind wing ochraceous- 

 orange (xv), with black basal area to middle of cell and scattered black
