The above description is taken from a specimen bred from 

 a cone rolled in a leaf of Alnus glutinosa, collected July 3,

 Four others collected July 3 to 22, issued July 14 to August 4. 



From material collected from the same food plant during 

 August, 1914, imagoes appeared in September, which are be-
