The Linnean Ichneumon extensor was supposed by 

 Gravenhorst to be Pimpla rohorator, Fab., but the type- 

 specimen having now been verified by Fitch, the name 

 is restored to the present insect. Described from 1 male, 

 7 females taken in Darenth Wood, and Devonshire ; 

 found by Bignell at Ivybridge ; in Ireland, not un- 

 commonly, by Haliday ; and generally distributed in 

 northern and central Europe. First taken, according to 

 Nees, in the Sudetsch mountains of Bohemia ; Katze- 

 burg's specimens were reared by Nordlinger at Grand 

 Jouan in the beginning of June from Sericoris Nord- 

 lingeriana, Eatz., and Coccyx ? Mulsantiana, Eatz. ; by 

 Brischke and others from Tortrix rosana and viridana, 

 L. ; cratcegana and diversana, Hub. ; Phlceodes immim- 

 dana, Fisch. ; and in England by Colquhoun out of 

 Depressaria nervosa, Haw.
