A common species ; variable in size, and especially so in colour. 

 The ground-colour ranges from pale drab to dull ferruginous, or 

 subochreous. The is extremely rare in cabinets, and is very 

 much smaller than the cJ .

 at Sanderstead, Stoat's Nest, and other Downs south of London. 



6. Branderiana, Linn. Alis anticis favillaceis ; fascia lata basi al-

Head dull, ash-coloured in front, with an ochreous tinge behind. 

 Eace dull, ash-colour, palest below. Eyes black. Palpi as long as 

 the head, dull, ash- colour, fuscous at the apex. Antenna dull, ash-

 fuscous. The costa maculated throughout towards the apex, the 

 maculations disposed in pairs ; the basal patch occupies one-fourth 

 the length of the wing ; very slightly streaky ; the central fascia 

 angulated on both edges, and dilated at the -dorsal margin, on which, 

 near the anal angle, is a dark brown, sometimes blackish, quadrate 

 patch ; the pale portions of the wing and apical margin streaked and 

 maculated with brown. Apical scales fuscous, with dull, drab bases. 

 Cilia similar, but paler. Posterior wings very pale grey, clothed with 

 coarse fuscous scales, slightly darker at the margin. Marginal scales 

 fuscous, with pale drab bases. Cilia very pale drab at the apex, grey

This species varies considerably in the ground-colour of the 

 anterior wings, also much in size, as well as in the intensity of 

 the markings. It is far from common. 



The imago appears at the end of June, and beginning of July. 

 It occurs at the New Forest, Hants ; Ardley Wood in Essex ; in 

 Worcestershire ; among Aspens and Poplars, on which trees the 

 larvae feed. ^_
