246 THE MOTHS OF THE BRITISH ISLES. 



Maple Pug {Eupithecia inturbata). 



The fore wings are greyish brown, with many darker cross 

 lines ; the outer margin is darker and traversed by a pale line ; 

 discal dot, dark grey and not very distinct (Plate 98, Fig. 6). 

 This species was long known as subciliata^ Guenee, but is now 

 referred to iiittirbata^ Hiibner. 



In May and June the caterpillars may be beaten from maple, 

 which is apparently the only food plant, and of which they have 

 a decided preference for the flowers. When full grown the 

 larva is yellowish green with a purplish stripe along the back, 

 and whitish lines along the sides. 



The moth may be jarred from the branches of the maple in 

 July and August ; it is occasionally seen resting on fences, etc. 

 It seems to be found in England and Wales, in most places 

 where there is a mature growth of maple. 



The Angle-barred Pug [Enpithecia hmotata). 



The greyish-brown fore wings of this species (Plate 98, 

 Fig. 7) are crossed by darker oblique lines, which are angled 

 on the front margin ; the submarginal line is white and irregular, 

 especially at each end. 



Caterpillar, ochreous grey, inclining to pinkish, marked on 

 the back with white-edged, ptu-plish- or reddish-brown blotches, 

 and on the sides with reddish or purple spots ; a whitish line 

 low down along the sides. It feeds on the flowers of wormwood 

 and mugwort {Artemisia)^ from August to October. 



The moth, which is uncommon and very local in England, is 

 out in July. It occurs in Devonshire (Exeter district), Kent 

 (Wye), Essex (Shoeburyness), Lincolnshire (Skegness, etc.), 

 Lancashire and Cheshire (coast sand-hills, Macclesfield, etc.), 

 and Durham (Hartlepool).
