ICHNEUMON-FLIES — GELINAE : MESOSTENINI 215 



This subspecies is structurally the most distinct of the five, but the 

 few specimens of the subspecies altonii available from Labrador are 

 rather close to fabricii. Possibly larger collections would show that 

 fabricii should not be considered as restricted to Greenland.
