The genus under this name, (loul)tfully synonymised hy hini 

 with that previously erected by liartig, was brought forward by 

 Holmgren (Sv. Ak. Handl. 1855, p. 385) as comprising that 

 section of Folyhhistus. Htg., liaving the clypeus contiiuious with 

 the face and not divided from it by a transverse sulcus, which 

 feature, he tells us, will distinguish its species from the remainder 

 of their subfamily. He is, however, in error in supposing the 

 hosts to be Lepidopterous, since in every case they have hitherto 

 proved to be the Tenthredinid genera Nematus and Dlneura. 



A dozen European species, and thi'ee or four American, have 

 been relegated to this genus ; but only two Indian forms are at 

 present recognised. 



The genus Cj/plumza is placed among the Tryi'honini by its 

 author, who entirely failed to note the pectination of the tarsal 

 claws in his elaborate diagnosis {loe. cit.), where he considers it 

 allied, in Ashmead's tables of 1900, to Gensia, !Forst., a quite 

 untenable position. I have examined the type and am satisfied 

 of its synonymy with Hartig's genns.
