Grunow 1. e. places this species as a Hantzschia, but with a query. 

 This is however undoubtedly correct. Wben I give a figure of it, it is 

 because the form found by me is substantially larger and on the whole 

 somewhat more elegantly built than Grunow's H. dubrav.. but I have 

 no doubt whatever that they are identical.
