PTEROMALIDAE OF N.W. EUROPE 61 



I have only been able to make a critical examination of specimens of rufa from 

 Britain and Czechoslovakia ; probably, however, the species will prove to be 

 quite widely distributed in Northern and Central Europe. 



Biology. Some of the published host-records for " cornigera " may actually 

 refer to rufa but this cannot be checked without an examination of the material on 

 which the records are based. Dr. Boucek has shown me material of rufa from 

 Central Europe which he said were reared from Anobiidae, Agrilus and Xylocleptes. 

 Szczepahski's (i960 : 417-418, 421) notes on the biology of the species he calls 

 cornigera almost certainly refer to rufa (Walker) ; he states that his observations 

 indicate that it attacks Anobium punctatum (DeG.), very probably as a secondary 

 parasite through Spathius exarator (L.) (Braconidae). 



Cerocephala sp. indet. 



? Cerocephala eccoptogastri Masi, 1922 : 189-193, $ $. 



? Cerocephala cornigera Russo, 1938 : 206-215, $ $ [nee Westwood] 



Specimens of this species from Turkey, Palestine, and Egypt, are contained in the 

 BM(NH) ; some are determined as eccoptogastri Masi, others as cornigera Westwood. 

 I have mentioned the characters by which it differs from rufa (Walker) in the 

 addendum to my key above. It may well be eccoptogastri Masi, the types of which 

 I have not seen. It may also be identical with the species described, erroneously as 

 cornigera, by Russo (1938) and recorded from Italy and Sicily as a parasite of several 

 Scolytidae. 



CHOETOSPILA Westwood 



Choetospila Westwood, 1874 : 137. Type-species : Ch. elegans Westwood, by monotypy. 

 Spalangiomorpha Girault, 1913 : 333. Type-species : S. fasciatipennis Girault, by original 



designation. 

 Choetospila Westwood ; Waterston, 192 1 : 19-21. 

 Choetospila Westwood ; Gahan, 1946 : 352. 

 Chaetospila [sic] Westwood ; Nikol'skaya, 1952 : 250-255. 

 Choetospila Westwood ; Peck et al., 1964 : 28. 



Spalangiomorpha Girault was placed in synonymy with Choetospila Westwood by 

 Girault himself (igiyd : 37). Both Waterston (1921 : 25) and Gahan (1946 : 352) 

 accepted this synonymy. 



Several species of Choetospila are known ; Ch. elegans Westwood, which is para- 

 sitic on weevils in stored grain, has been transported to many parts of the world in 

 shipments of stored products and is now cosmopolitan.
