CHRYSOCORYS, C.rtis. 



Chrysocorys festaliella, lluhuer. 

 (Plate I. Fig. 1.) 

 iSchreckenstehna festaliella, Hiibn., Wocke, Cat, 2705. 



Of this species six specimens occurred on the 29th 

 May, 1871, in Mendocino County, California, and 

 three more early in June of the following year on 

 the coast near Klamath River. They appear to be 

 in all respects the same as European specimens, 

 having also the same habit of frequenting one or 

 more species of the genus Ruhus. 



The only Chrysocorys at present described as 

 occurring in North America, C. erythriella, Clemens 

 (Proc. Ac. Nat. Sc. Phil. 1860, p. 168), is very closely 

 allied to this species. 



I have examined Dr. Clemens's type in the collec- 

 tion of the Entomological Society of Philadelphia, as 

 well as two specimens in Mr. Stainton's collection. 



The differences which exist between them are well
