GREY SCALLOPED BAR. 329 



the second in July and August. It may be found in clover 

 fields and on chalk slopes, etc., where the food plants flourish ; 

 although it is an active day flyer, it is not difficult to capture 

 with the net. It is most plentiful in southern and eastern 

 England, but its range extends throughout the United Kingdom 

 to Clydesdale, and the species is widely distributed in Ireland. 



The distribution abroad extends to East Siberia, Amurland, 

 and Japan. 



Grey Scalloped Bar {Scodiojta fagaria). 



In its typical form this species (also known as belgiaria^ 

 Hiibner) is grey, more or less tinged with ochreous, speckled 

 with brownish grey, and crossed by black-marked brownish- 

 grey lines. The bulk of British specimens, especially those 

 from southern localities, are whitish grey, thinly sprinkled with 

 darker grey scales in the male, and sometimes heavily powdered 

 in the female; a pair are figured on Plate 144, 1^,2 $. The 

 whiter form of the male, occurring in Britain chiefly in the New 

 Forest, Hampshire, has been named albidaria^ Staudinger. 



The roughened caterpillar is figured on Plate 142 (photo by 

 H. Main). In general colour it is dingy brown, with a whitish 

 stripe along the back and some greyish marking on the sides. 

 It feeds on ling and heath ; growing slowly in the late summer, 

 but more quickly in the spring, after hibernation, when it may 

 be obtained at night from the tips of the heather twigs, either 

 by searching or by means of the sweeping net. The moth is 

 out in June and July in the south, and later in the north. It is 

 found on moist heaths, moors, and mosses ; when resting on 

 the dark-coloured earth it so closely resembles a stone that it is 

 probably frequently passed unnoticed. 



The species is apparently more plentiful in the New Forest 

 than in its other known southern localities (Kent, Surrey, Berk- 

 shire, Sussex, and Dorset). Its range northwards in England
