£24 THE MOTHS OF THE BRITISH ISLES. 



The Cream Wave (Acidalia {Lepiomeris) remuiaria). 



This species (Plate 49, Figs, i, 2) has the wings white or 

 -ochreous white, becoming rather smoky grey on the front edge 

 of the fore wings, and sometimes this tinge spreads all over the 

 wings. In well-marked specimens there are two dark, wavy, 

 cross-lines, a dusky central shade, and a dusky shade-like stripe 

 along the outer area beyond the second line ; the first line of 

 the fore wings is often placed close to the central shade, and 

 sometimes it is merged in it. Not infrequently the lines are 

 barely traceable, but almost as often the wings appear to have 

 a pair of lines only, and these distinctly darker than usual. 



The caterpillar is rough, long and slender; grey-brown with 

 irregular darker marks, a pale line along the middle of the back, 

 and a dark cross on the back of ring ten. The notched head 

 is pale brown with a black V-mark. It feeds, from July to 

 September, on bedstraw {Galium)^ woodruff {Asperuld)^ dock, 

 sallow, etc. 



The moth is out in May and June, and often is plentiful in 

 woods throughout the greater part of England and Wales ; in 

 Yorkshire and northwards through Scotland up to Moray it is 

 rather local. In Ireland it has been found in Wicklow and 

 Louth, but more commonly in the south and west. 



The range abroad extends to Amurland and Japan. 



The Lesser Cream Wave {Acidalia {LeptomeHs) 

 immiitata). 



White, more or less tinged with ochreous or ochreous grey 

 in the male, is the general colour of this moth ; the wings are 

 crossed by several ochreous lines, the third line of the fore 

 wings and the second line of the hind wings rather wavy. All 

 the wings with central black dots, most distinct on the hind pair, 

 occasionally absent from fore wings. (Plate 49, Figs. 36,4?-)
