Anterior wings very pale yellowish-orange, with slightly darker clouds, and 

 with some very obscure streaks of silvery dots, most distinct on the costa, 

 and vanishing towards the inner margin ; cilia pale luteous : posterior wings 

 pale yellowish-brown.

Anterior wings glossy brown-black, very dark at the base, the apex tawny-

The posterior wings are sometimes pale, with a dark spot on the anal angle : 

 — probably a sexual distinction. 



Not very abundant : taken occasionally at Darenth, Birch, and 

 Coombe woods, in June; also near llipley, and in Devonshire.
