WAVED UMBER.

sometimes in July. The species is generally distributed, and 

 sometimes common in the caterpillar state, but seems to be 

 absent from the Scottish Isles. 



Waved Umber {He?nerophila (Synopsia) abniptaria), 

 A male and a female specimen are figured on Plate 130. The 



males are usually darker than the females, but they vary in the 



amount of darker clouding and suffusion. Three forms of 



the species have been named as follows— ab. brimneata, Tutt, 



a modification of the female 



rather more strongly coloured 



than the darkest typical male. 



Ab. fuscata, Tutt, sooty brown, 



tending to blackish ; both sexes 



somewhat paler in central area 



of fore wings. Ab. unicolor, 



Tutt, similar to ab. fuscata^ but 



without pale marking ; the 



thorax is also darker. (Plate 134, 

 Fig. 7, ab. fuscata.) The eggs, 



furnished by Mr. Norman Riley, 

 were verdigris green when laid, 

 but on the third day changed to 

 greyish. 



In general colour the cater- 

 pillar is greyish brown some- 

 times tinged with green ; pinkish 

 brown blotches along the back, 

 often united on the front and hind rings. In some cases the 

 caterpillar is almost black, with a lighter mark on front of the 

 first ring. It feeds on privet and lilac, and is said to eat currant, 

 broom, and jasmine : May to August. (Plate 133, Fig. 3-) 



The moth is out in April and May, and is fond of resting on 

 palings, trees, and even walls. It appears to be most plentiful
