Remarks. — The species is well established on southern Vancouver 

 Island, British Columbia, and probably will be found in Washington 

 State, across the Straits of Juan de Fuca, where oak is abundant. 



There is considerable variation in this species, wliich probably 

 accounts for some of the synonymy, but all figures of this species I 

 have seen are readily recognizable.
