Geographical distribution: — • Southern Sweden, Denmark and 

 England, but not known farther towards the south. 



Remarks: As Zetterstedt says "Stæg. in litt." the name is origin- 

 ally due to Stæger. I have seen Zetterstedt's types in Lund and 

 Stæger's specimens in our collection, which are co-types, The species 

 is, as said, known only from Denmark, southern Sweden and Eng- 

 land, but probably it is more widely distributed but has, as Verrall 

 thinks, been confused with boletina (see under this species).
