PTEROMALIDAE OF N.W. EUROPE 467 



Extra-limital species wrongly placed in Psilocera 



Metopon Deiphon Walker (1843*? : 161, $) is represented in BM(NH) by Type 

 Hym. 5. 693 ; the specimen appears to be near Spaniopus or Trichomalus. 



CALLIPRYMNA Graham 



Calliprymna Graham, 19666 : 295-297. Type-species : C. bisetosa Graham, by monotypy and 

 original designation. 



Calliprymna bisetosa Graham 

 (Text-figs. 344-348) 



Calliprymna bisetosa Graham, 19666 : 297-298, $.

CATOLACCUS Thomson 



Pteromalus sgen. Catolaccus Thomson, 1878 : 146, 152. Type-species : C. cavigena Thomson, 



by monotypy. 

 Catolaccus Thomson ; Ashmead, 1904 : 320, 322. 



Catolaccus Thomson ; Schmiedeknecht, 1909 : 328, 330, 355-356 [ex parte]. 

 Merisoides Masi, 1911 : 141. Type-species : M. crassiceps Masi, by monotypy. 

 Catolaccus Thomson ; Kurdjumov, 1913 : 5. 

 Merisoides Masi ; Kurdjumov, 191 3 : 5. 

 Catolaccus Thomson ; Nikol'skaya, 1952 : 223. 

 Catolaccus Thomson ; Peck et al., 1964 : 50. 



In the opinion of Dr. Delucchi, who has seen the type-species of Merisoides Masi, 

 this genus is the same as Catolaccus Thomson. 



Only one European species is recognized here ; this shows some variation, 

 however, and it seems possible that it may not be a homogeneous entity. 



Catolaccus ater (Ratzeburg) 

 (Text-fig. 302) 



Pteromalus ater Ratzeburg, 1852 : 233, <J ?• 



Catolaccus cavigena Thomson, 1878 : 152, $. 



PMerisoides crassiceps Masi, 191 1 : 141-145, $. 



Catolaccus ater (Ratzeburg) Kurdjumov, 1912 : 232-233, o* ?• 



Catolaccus ater (Ratzeburg) ; Boucek, 1965s : 8. 



Type material. Pteromalus ater Ratzeburg. Types presumed destroyed. Kurd- 

 jumov (1912) who had seen the type of ater, placed it in Catolaccus and cited C. 

 cavigena Thomson as a synonym ; his opinion has been generally accepted.
