NARROW-WINGED PUG. 247 



Ash Pug {Eupithecia fraxinatd), 



Veiy similar to the last mentioned, but smaller, and the 

 markings are less distinct (Plate 98, Fig. 8). 



The caterpillar is variable, but generally some shade of 

 green, occasionally purplish red ; lines on the sides yellowish, 

 and sometimes there are dusky purplish marks on the back. It 

 feeds, in August and September, on ash, and is said to eat 

 Artemisia^ Laurustiiiics^ and the flowers of scabious. The 

 moth is out in late June and July, and sometimes a second 

 generation appears in the autumn. 



This species, which by some entomologists is considered to 

 be a form of E. innotata^ is widely distributed over England, 

 south Scotland, and Ireland. Tatnarisciata., Freyer, is also 

 considered by some authorities to be a form of E. innotata. 



Some moths reared from larvas obtained, in 1905, from 

 Tamarisk, in Cornwall, have been referred to tajnarisciata. 



Narrow-winged Pug {Eupithecia 7ia?iata). 



The rather variable species represented on Plate 99, Figs. 

 I and 2, will easily be recognised by its long pointed fore 

 wings, which in colour are whitish grey, darkened by brownish 

 cross-stripes ; a whitish spot before the small, black discal dot. 



The long, thin, caterpillar, which feeds on Hng or heather in 

 the autumn, is whitish with a greenish tinge : the sides are 

 marked with red, and there are some reddish spots on the 

 back. 



On almost all heather-clad ground throughout the British 

 Isles, this pretty little moth will be found, more or less commonly, 

 during the months of May and early June, and sometimes there 

 is a second flight in July and August.
