and marginal scales dark fuscous, the latter with whitish bases. Cilia 

 whitish. Abdomen fuscous grey. $ Exp. al. 4-6J lin. Anterior 

 wings marked as in the tf , but usually more suffused, and not so 

 bright in colour. 



A very common insect on the Downs in the south of England, 

 variable in colour, and also in size. The ground-colour ranges 

 from pale drab to rich orange, and the markings from dusky 

 drab to rich ferruginous and chestnut colour. 



The imago appears in June, July, and August, among mixed 

 herbage, at Deal, Brighton, Dover, Mickleham, Croydon, San- 

 derstead, Charlton, in Hants, and other places.

 cJ Exp. al. 6-6 lin. 



Head mouse-colour, palest on the vertex. Face mouse-colour. 

 Eyes black. Palpi as long as the head, pale ochreous. Antenna? 

 pale fuscous. Thorax and patagia smoky brown or umber, the latter 

 greyish at the apex. Anterior wings with a rich satiny gloss ; dark 

 umber, inclining to smoky black, with the apex ochreous, and small 

 ochreous patches on the costal and dorsal margins, and lustrous blue 

 streaks upon the disk. The smoky-black colouring extends nearly 

 to the apex, where it softens into dusky ochreous. In the middle of 

 the costa is a geminated ochreous spot, and two smaller simple ones 

 near the apex ; near the base on the dorsal margin is a small 

 ochreous cloud ; at the base is an interrupted lustrous blue patch, 

 followed by a curved streak going across the disk ; another similar 

 one proceeds from the middle of the costa to near the anal angle, and 

 a third crosses the apical region ; all lustrous blue. Between these 

 streaks are several minute tufts of elevated scales, which assume a 

 lustrous blue tinge when viewed from the base, jet-black from above, 

 and greyish towards the base. Apical scales dull ochreous, mixed 

 with dusky scales towards the anal angle. Cilia paler. Posterior 

 wings glossy, fuscous grey. Marginal scales pale fuscous. Cilia 

 grey. Abdomen ochreous at the base, becoming blackish towards 

 the apex ; the caudal tuft mixed with black and ochreous scales. 

 $ Exp. al. 6-6 lin. 



A rare species ; constant in size but variable in colour, the 

 ochreous markings being more or less present. 



The imago appears in June and July, frequenting Oaks ; 

 occurring at Tonbridge, Darenth Wood, and Black Park. 



Obs. This insect seems ill-located here : from its having tufts 

 of elevated scales on the upper wings, it comes near Peronea, 

 but the shape of the wings themselves does not warrant its 

 position in that genus.
