DARK-BARRED TWIN-SPOT CARPET. l8l 



feeds on lady's mantle {Alchemilla), chickweed, groundsel, etc., 

 from September to May. 



The moth is out in July and August, and in England is 

 only found in the mountain districts of Yorkshire and the more 

 northern counties. It has been reported from the high-lying 

 district on the border of Cheshire, between Macclesfield and 

 Buxton (Day), and from Llantrissant, Glamorganshire, S. 

 Wales (Evan John). Generally distributed through Scotland 

 and the Isles. Widely spread, but local, and not always 

 common, in Ireland. 



Abroad, the range extends to Eastern Siberia, Amurland and 

 North America.

Portraits of three examples of this species will be found on 

 Plate 75, Figs. 1-3. The ground colour of the fore wings is 

 whitish tinged with pale ochreous or greyish ; the central band 

 is blackish with darker wavy lines running through it near the 

 edges, and not infrequently the middle area is greyish, either 

 on the upper half, or throughout from front to inner margins ; 

 a narrow patch at the base of the wings is of the same colour 

 as the central band, and is followed by a reddish-brown streak ; 

 as a rule, there is an irregular reddish-brown line, commencing 

 in a cloud on the front margin, and sometimes stripe-like, 

 beyond the pale edging of the central band ; in ab. coarctata^ 

 Prout, the central band is much narrowed ; the two black dots 

 on upper part of the outer margin, generally well in evidence, 

 are occasionally united, but sometimes they are very tiny. 

 The hind wings are whitish, more or less sprinkled with dusky 

 scales, chiefly on the basal two thirds, and crossed by dark- 

 grey wavy lines.
