This translation of the original description is introduced here for the 

 benefit of the many entomologists who are not likely ever to see the 

 rare volume in which it so unexpectedly occurs ; also in the hope that

 recovering and placing within the reach of American students this con- 

 spicuous representative of the fauna of the Pacific coast.
