centre of the wing, and a dark band below the middle 

 of the hind-wings are the most conspicuous. 



The larva is blackish-brown, marbled with ochreous 

 on the back ; the sides are much wrinkled ; there are 

 two minute humps on the back of the ninth and tenth 

 segments. It feeds on lilac and privet in July and 

 August. 



The perfect insect appears at the end of April and 

 during May, and we often see it sitting with all its wings 

 spread out on palings ; it may also be met with flying 

 in the evening, and it conies not unfrequently to light. 



FAMILY IV. 

 CLEORA LICHENAEIA. 



This pretty species is common and generally distri- 

 buted throughout England and Ireland, and has been 

 noticed in more than one locality in the west of 

 Scotland. 



The expansion of the wings i3 from 1 to IJincli. The 

 fore-wings are whitish, much dusted with greenish-grey, 

 with a central black spot and two transverse black lines, 

 the first, not far from the base, rather regularly curved, 

 preceded by a slender whitish band ; the second, which 

 is angulated and much indented, lies beyond the middle 

 of the wing, and is followed by some pale blotches. 



The larva is pale green, sometimes almost whitish- 

 green, sometimes more yellowish -green; there are two 

 small humps on each of the fifth to twelfth segments, 

 and between the humps there is frequently a black spot ; 

 the spiracular line is wavy, blackish. It feeds in the 

 autumn and early spring on the lichens growing on the 

 trunks of various trees.
