158 BANKS [466] 



Leaving out the species restricted to Alaska (some of which 

 will doubtless be found on the West Coast), it will be seen that 

 the fauna is very similar to that of the State of Washington. 



The Perlidae are represented chiefly by species of moderate 

 size ; the Trichoptera are represented by many species of large 

 size. As a whole the collection is more brightly colored than 

 those of more temperate latitudes.
