The wings are broad and much dentated, dark brown with 

 the abdomen paler. An ochre-yellow band crosses the wings 

 obliquely, and is intersected on the hind-wings by a brown line, 

 running on the fore-wings on the outer side of the ocellus, 

 where it becomes attenuated and finally lost in a white band, 

 which commences at the costa, and meets it at an angle.
