transverse stripe ; and a specimen in Mr. Sydney Webb's 

 collection has the spots of the middle of the fore wings much 

 drawn together. Otherwise this species is rather constant in 

 markings. 



On the wing at the end of May and in June. 



Larva rather cylindrical, the second segment broader, with 

 side prominences ; from the fifth, each segment has a faint 

 dorsal swelling ; sides folded ; dull grey-brown or red-brown 

 mixed with paler; head shortly squared, in the middle is a 

 heart-shaped division deeply angulated. (Wilde.) 



August and September on lichens upon oak and birch. 

 (Dr. Hofmann.) 



Pupa dark red-brown, with a forked hooked spike upon 

 the end of the projection of the anal segment. In a slight 

 cocoon under moss or lichens on the trunk of a tree. (Hof- 

 mann.) Apparently the winter is passed in this condition. 



The moth is said to sit during the day upon the trunks or 

 branches of trees, much concealed by its close resemblance to 

 a patch of lichen. The late Mr. Samuel Stevens took many 

 specimens in the year 1849 by sweeping the upper branches 

 of oak-trees in the New Forest with a long pole; and the 

 late Mr. G. Baker informed me that it used to sit on the 

 trunks of beeches, as well as of oaks, in that Forest. Here — 

 near Lyndhurst and Brocken hurst — it was not scarce, but 

 about 1872 it suddenly disappeared. The Rev. W. W. Fowler 

 records that at the end of July, or beginning of August, of 

 that year, Mr. George Gulliver, of Brockenhurst, saw an 

 unusual number of examples sitting upon the tree-trunks, 

 but all were females in worn condition. A few days after- 

 Avards he could find none, and so far as can be ascertained 

 the insect has not been seen there since. In 1876 and 1877 

 Mr. W. H. B. Fletcher worked hard for it in that Forest in 

 its former well-known haunts, but could find neither moths 

 nor larva^. Another locality was Tilgate Forest, Sussex,
