ANISOTA STIGMA 285 



Tlie larvae are to be found on low-growing oaks, 

 their anal props fixed on a twig or leaf-stem, and their 

 bodies lying along the edge of the leaf on which they 

 are, or have been, feeding, for they frequently rest 

 where they have fed, their horns standing out like the 

 points of an oak-leaf, although they cannot be said to 

 resemble the leaf. 



The moths are not very pretty. They are ocher- 

 brown, more or less suffused with pinkish purple. The 

 fore wings are crossed by a purplish line, and are 

 thickly dotted with black. There is a conspicuous 

 white discal dot. The hind wings are less dotted, 

 more purplish, and crossed by a purplish band. The 

 male is smaller than the female, but has similar marks, 

 and his antennae are broadly pectinate at the basal half 

 and simple at the tip. The female's antennae are simple 

 throughout their length. Like all the ceratocampids, 

 stigma has a small head, a large thorax and abdomen, 

 and is very " furry " in parts. 



The larvae are said to live on hazel and chestnut as 

 well as oak, but we have found them on oak only, and 

 more on red and scrub oaks than on any other.
