236 THE MOTHS OF THE BRITISH ISLES. 



Triple-spotted Pug {Eitpithecia trisignaria). 



The most noticeable markings on the rather shiny, pale- 

 brown fore wings of this species (Plate 97, Fig. 13) are the 

 black discal spot and two blackish clouds above it on the front 

 margin. 



The stoutish caterpillar is green, with three darker green 

 lines along the back, and a wavy yellowish line low down along 

 the sides ; head, black. It feeds, in the autumn, on flowers 

 and seeds of angelica and cow-parsnip, but the former is its 

 chief food. 



June and July are the months for the moth, but it is rarely 

 met with in the open. The only English counties in which the 

 species has been noted are Surrey, Sussex, Dorset and Devon 

 in the south ; from Herefordshire in the west its range extends 

 through Worcester, Warwick, Leicester, and Derby to Lanca- 

 shire and York. In Scotland, Renton records it as common 

 at Hawick, in Roxburghshire; and it was recorded from 

 Argyllshire in 1902. Hardly known in Ireland. 



Larch Pug {Eupitheda lariciatd). 



This species (Plate 97, Fig. 3) is very like that next referred 

 to, but the fore wings are rather longer, the ground colour is 

 whiter, and the dark-grey or blackish cross lines are rather 

 more angled and slanting; the hind wings are paler, and 

 especially so on the front margins. 



The long caterpillar is bright green, with a darker green line 

 along the back, merging into reddish on the last ring ; some- 

 times reddish ochreous with the line along the back brownish. 

 It feeds, in June and July, on larch, and will also eat spruce. 



The moth is out in May and early June, and may be jarred 

 from larch trees, or sometimes be found at rest on their stems.
