Wings cinereous-red, thickly sprinkled with reddish or fuscous : the anterior 

 above with three somewhat equidistant red- brown strigse in the middle ; the first 

 curved towards the base ; the second in the middle broader and of a deeper 

 hue; the third somewhat oblique behind the middle; the apex rufescent, 

 with a short semilunar striga: cilia with ustulated spots: posterior pale, with 

 sometimes an obsolete striga or a pale streak. Beneath, the wings are very 

 thickly irrorated with dark reddish-fuscous or cinerascent, the anterior have 

 three transverse strigae in the middle, the central one with a white lunule: the 

 posterior have a fuscescent striga before the middle, in whicli is a pale lunular 

 spot, and a white streak behind; from thence to the hinder margin the wing 

 is darker. Females in general darker than the males. 

 Extremely variable in tint, scarcely two specimens occurring precisely similar ; 

 the strigae are also more or less distinct, and sometimes vary slightly as to their 

 relative positions. 

 Caterpillar generally griseous, annulated with ferruginous, with some black and 

 yellow spots at the base of the tubercles and on the sides: — sometimes brown, 

 with a ferruginous-red dorsal line, and larger reddish spots on the sides of the 

 hinder segments : — it feeds on oak, willow, alder, &c. :— the imago appears in 

 March or April. 



Not very uncommon in woods and bushy lanes towards the end 

 of March and beginning of April within the metropolitan district.

Very similar to the foregoing, but always of much smaller size, and of a paler 

 hue: with the strigae more obsolete, and not equidistant; the wings more 

 dentated, and the females much paler than the males: the under surface of 

 the wings is of a brighter and clearer red, tinted with purple (especially in 

 the males), and the central lunule is less distinct. 



With regard to the specific distinctions between this and the foregoing species, 

 there is considerable doubt; the extraordinary facts relative to which are
