Phygadeuon abdominator, Gray., I. E. ii. 728, var. 2. 
This species is named by Taschenberg in ‘Die 
Schlupfwespen-familie Cryptides,’ page 52, and is de- 
scribed by Gravenhorst, [chn. Europ., vol. 11., page 728, 
as var. 2 of Phygadeuon abdominator. I have taken two 
insects which agree exactly with Taschenberg’s descrip- 
tion of P. aberrans (Gravenhorst makes no mention of 
the red marks at the apex of the scutellum); they how- 
ever certainly are not Phygadeuon, but true Ichneumons, 
and, I believe, only small specimens of Jchnewmon lanius. 
Wesmael gives, as the female of J. lanius, Gravenhorst’s 
Phygadeuon terminatus, l.c. vol. 11, p. 664, which, as far 
as concerns the coloration, agrees well with J. lanius of 
Wesmael; but Gravenhorst says, ‘‘segmenti 1 levi 
nigro”’; Wesmael, in Tent., p. 105, ‘‘ Post-petiolus 
feminz confertissime punctatus.” Holmgren says the 
same (Ichn. Suec., vol. 1., p. 159). In this respect the 
female of J. lanius differs from Phygadeuon terminatus. 
I think Phygadeuon aberrans, Tasch., will prove to be a 
synonym of Ichnewmon lanius.

P. probus, Tasch., Zeits. Ges. Nat. 1865, 42, 52, 2. 
In the description of improbus or probus, neither 
Gravenhorst nor 'aschenberg mentions the whitish short 
line or spot on the frontal orbits ; the metathorax varies 
much in the distinctness of the areas. From Taschen- 
berg’s descriptions I can detect no sufficient difference 
to form another species from the var. 2 of Gravenhorst.
