the antennae longer and with a denser pile than in 

 rapce. 



The larva is described by Kaltenbach (Pfl., 431). It 

 is 9'" long ; the head is orange-yellow, body olive green, 

 with small white points ; on the sides and belly the 

 colour is dirty white, while on the inner side of each 

 segment there are two green spots, one under the other. 

 It feeds in September on low growing ash trees (Fraxi- 

 nus), eating along the edge and underside of the leaf. 



Rare. I have only seen one $ from Norwich (J. B. 

 Bridgman). 



Continental distribution : Sweden. France, Tyrol, 

 Austria.
