John Murdoch described this species from Point Barrow and Cape 

 Smyth, Alaska, in 1885. In 1930 it was recorded from the Gulf of 

 St. Lawrence from specimens taken by the Cheticamp Expedition. 

 In the U. S. National Museum there is a male taken at Egg Harbor, 

 Labrador, by Owen Bryant, August 10, 1908. 



Murdoch's description being very brief and his figure lacking 

 nearly all detail, a figure of a male 20 mm. in length, and a short 

 diagnosis of the principal characters are given here.
