British Braconidce. 169 



An abundant species throughout Europe, and found 

 gregariously on bushes in shady places ; some of the 

 females live more thaii one season in this country, and 

 may be found in winter among dead leaves or moss, 

 especially at the roots of trees, Eatzeburg records the 

 breeding of a specimen by Dahlbom, at Lund, on Sept. 

 7tli, from a piq)a of Cionasfnixini, DeGeer.

I have not met with this species, and the description 

 is taken from the authorities cited, with the synonymy 

 given by Eeinhard. Taken formerly by Haliday in 

 Ireland, less commonly than rujiconiis.
