PTEROMALIDAE OF N.W. EUROPE 427 



They were seen by Kurdjumov who redescribed the species (1913 : 22) and noted 

 that it probably represented a new genus near Habritys. Ferriere (1952 : 322) 

 proposed the genus Xiphydriophagus for it. 



Pteromalus xiphydriae Fahringer. Types in Hochschule fur Bodenkultur, Vienna ; 

 re-examined by Novitzky, on the basis of which Ferriere (1952 : 322) decided that 

 xiphydriae was a synonym of meyerinckii. 



Britain, Germany, Moravia. 



Biology. Reared from Xiphydria camelus (L.) and X. prolongata (Geoffr. in 

 Fourcr.) {=drornedarins (F.) (Hym., Xiphydriidae). 



Xiphydriophagus meyerinckii has the distinction of being the first Chalcidoid whose 

 life history has been filmed (in " The Alder Woodwasp " made in the Department of 

 Forestry, Oxford, by G. H. Thompson and E. R. Skinner). The film shows how the 

 female meyerinckii enters an old burrow of the host, the woodwasp Xiphydria camelus. 

 When such a burrow is near to a living woodwasp larva, the parasite bites a tunnel 

 through the solid wood towards it, and on entering the woodwasp gallery she 

 paralyzes the larva and lays her eggs upon it. A year later her offspring escape by 

 following the route made by the mother.

Only one European species is known, but another has been described from North 

 America by Wallace (1954 : 199-200).

Type material. Types of Pteromalus brevicornis Ratzeburg and P. (S.) panne- 

 witzii Ratzeburg presumed destroyed. The name brevicornis, however, has been 

 generally accepted. Boucek (1958a : 396) said that he believed pannewitzi Ratzeburg 

 was probably the same as brevicornis ; I had come to the same conclusion, from 

 Ratzeburg's description and the host which he mentioned, " Crabro cephalotes " 

 [=Clytochrysus sp.]. 



Britain, Ireland, Sweden, Germany ; no doubt widely distributed in Europe.
