126 THE MOTHS OF THE BRITISH ISLES. 



specimens are shown on Plate 49 ; two from Eastbourne, 

 Figs. 5 $ , 6 ^ , and one from Essex, Fig. 7 ^ . 



The long caterpillar is very pale slaty-olive, with three paler 

 lines along the back, the central one edged on each side with 

 olive, darkest on the last three rings ; spiracles black, and 

 under surface of the body pale slate blue (adapted from 

 Porritt). It feeds on various low-growing plants, among 

 which, yarrow, mugwort, chickvveed, cinquefoil, and knotgrass 

 have been mentioned ; also, it is said, on sallow. There are 

 certainly two broods in the south, one feeding up in the 

 summer, and the other hatching in September, and after 

 hibernation attaining full growth in May or June. Moths 

 of the first generation are on the wing in June and July, and 

 of the second in August and September. Although sometimes 

 found inland, the species is more especially attached to the 

 coast, and is found in nearly all the seaboard counties of 

 England, Wales, and Ireland. In Scotland, it occurs in 

 Wigtownshire, and very dark specimens have been obtained 

 on rocks in dry pastures at Ardrossan ; June to end of July. 



The Lewes Wave {Addalia {Leptomeris) immoratd). 



Although the late Mr. S. Stevens exhibited a British specimen 

 of this species, as a curious variety of Strenia clathrata^ at a 

 meeting of the Entomological Society of London in 1868, it 

 was not until the year 1887, when Mr. C. H. Morris captured 

 two specimens in Sussex, that the insect became recognized as 

 a native. It is probable that the earlier example, taken some 

 years before it was shown at the meeting referred to, may have 

 come from the same locality in the Lewes district where the 

 later specimens were captured. Anyway, the species has, so 

 far, not been recorded from any other part of our islands, but 

 it continues to be found in its original haunts, described as 

 " some heathy ground," up to the present day. (Plate 49, Fig. 9.)
