INTRODUCTORY PAPERS ON ICHNEUMONID^. 223 



Mr. E. A. Butler bred one specimen of S. deplanatus from a silky 

 white cylindrical cocoon, with an opaque white girdle round its 

 centre, which was 3 lines long. The host was a lepidopterous 

 larva, feeding on honeysuckle, collected in Brecknockshire. 

 Brischke sa3's that S. gagates is a parasite of Anthomyia 

 radicum. The fact of a species being bred from a cocoon shows 

 that the genus does not belong to the Ichneumonidfe.
