DWARF PUG. 225 



Marbled Pug {Eupitheda irriguata). 



The fore wings are whitish and rather shining, the discal 

 spot is black and very distinct, but the dark grey-brown mark- 

 ings, which are only well defined on the front and outer 

 marginal areas, vary in intensity (Plate 93, Fig. 9). 



The long, slender and roughened caterpillar is dull yellowish 

 green ; three lines along the back, the central one reddish and 

 expanded on the middle rings, the others yellowish ; head, 

 reddish. It feeds on oak, in late May and in June. The moth 

 is out in April and May, and is sometimes found on fences or 

 palings in the neighbourhood of oak woods, but may be jarred 

 from the oak boughs, on the undersides of which it usually sits. 



The New Forest in Hants is, perhaps, the best British 

 locality for the species, but it has been found in Dorset (Glan- 

 ville's Wootton), Devon (Exeter district, Tiverton, etc.), Sussex 

 (Abbots Wood, St. Leonard's Forest, etc.), Wilts. (Savernake 

 Forest) ; also oak woods in Surrey, Berks., Gloucester, Here- 

 ford and Glamorgan. On the eastern side it occurs in Suffolk 

 ^Bury and Needham), and Norfolk. 



Dwarf Pug {Eupithecia pusillata). 



The fore wings of this species (Plate 93, Fig. 12) are p»le 

 greyish white, discal spot black, cross lines irregular dark 

 grey inclining to brownish, usually most distinct on the front 

 margin. 



The long, slender caterpillar is orange-red or dull ochreous 

 green ; three dusky olive lines along the back, the central one 

 often only distinct on the front rings ; a yellow line low down 

 along the sides. It feeds, in June and early July, on spruce 

 {Picea excelsa). The moth is out in May and June, and rests 

 by day among the branches of the spruce.
