Very rare everywhere in Middle Europe. In this country a single speciaen 

 (o) is found in gnaw-crumblings in a hollow beech in Dyrehaven at Copenha- 

 gen (S8. 4. 191?. E. Fosenberg), an other (o ), supposedly also from Nord- 

 sjaelland, but of an older date, in in the author's collection. In Middle 

 Europe it is found in company with ants ( Lasius f uliginosus ) , hut also under 

 bark of trees and at outflowing tree«ap. In North Europe it is hereto- 

 fore not discovered.
