No examples of this species are found in the 

 Ottawa Museum collection and only one Canadian 

 specimen in that of the Philadelphia Academy. 

 Professor Reighard, however, took it frequently 

 during the explorations in Lake Erie, several 

 times on the Canadian side, and Miss Ryerson 

 found it common in Georgian Bay.
