ADDENDUM 231 



ADDENDUM 



Mr. Ralph Hopping, of the Canadian Forestry Service, has very 

 recently submitted to me a species of Listrus, collected at Vernon, B. C. 

 It has proved to be an undescribed species to which I have given the 

 name provincialis, n. sp. The description will in all probability appear in 

 the Canadian Entomologist in the near future. The types will be placed 

 in the National Collection at Ottawa. Provincialis should follow difficilis 

 Lee. in the synoptical arrangement given above.
