i6o I.F.PIDOPTERA. 



paier between the segments; s]iiracLil.iv region paler, with a 

 still paler line below ; head shining brown, jaws black ; 

 dorsal plate shining brown or dark brown, its anterior mar- 

 gin white, and sometimes edged with white behind ; anal 

 plate green or yellowish-green ; hairs of moderate length ; 

 spots paler than the ground colour, generally sm;ill Lnd 

 inconspicuous. (Mr. E. A. Atniore.) 



May to the beginning of July, on Mijrica f/alc, drawing 

 togetlier the leaves of a terminal shoot, very often includ- 

 ing an old seed-husk. Abroad it is said to feed also on 

 birch, hazel, and Vacciniuin vlif/iiiosum. 



Pupa blackish, with the wing-covers tinged with brown. 

 In a slight web in the larval habitation. 



The moth hides among its food plant by day, and is then 

 difticnlt to disturb, but the males become active at sunset 

 and II V with great swiftness over the same plants ; the 

 females commencing to fly a little later in the dusk, but 

 being very swift and powerful on the wing. In this country 

 it seems only to have been found among sweet-gale. It was 

 first met with here about the year ] 881, by Mr. E. A. Atuiore, 

 who reared it with other Tortrices from the sweet-gale grow- 

 ing upon boggy heaths in the neighbourhood of King's Lynn, 

 Norfolk. There it continued to occur pretty freely for some 

 years, but now has. as I understand, become scarce. Pro- 

 bably this is a mere fluctuation consequent on its being much 

 infested with ichneumon parasites, and I hope that it will 

 again increase in numbers ; but its close restriction to sweet- 

 gale here, even in places where there is plenty of birch, seems 

 remarkable. 



Abroad it is found commonly thi'oughout Central Europe, 

 also in Livonia and in North-west Russia.
