Professor Lindberg having recently investigated the forms of 
this species, and published the result in ' Notiser ur Sallskapets pro 
Fauna et Flora Fennica Forhandlingar,' xiii., p. 401, and having 
also liberally communicated to me specimens of each, I take this 
opportunity of figuring them, since they constitute a series pre- 
cisely parallel to the three varieties of 8jph. subsecundum previously 
illustrated. 
Of the var. ^. I have not seen British specimens, but there is 
little doubt it will eventually prove to be indigenous.
