PTEROMALIDAE OF N.W. EUROPE 849 



has the marginal vein about 3 times as long as the stigmal vein, and the postmarginal 

 vein is long. Peck (1963 : 611) placed Paracaratomus in Miscogasterini.

Three species occur in North America, including megacephalus (F.) ; but only the 

 latter species is known from Europe.

Type material. Cynips megacephala Fabricius. Syntypes, two specimens, one 

 in Universitetets Zoologiske Museum, Copenhagen [LECTOTYPE], the other in 

 the private collection of Fabricius in Kiel University. The specimen in Copenhagen 

 was selected a lectotype in 1962 by Hedqvist and I now validate his selection ; it 

 is labelled " Caratomus megacephalus det. Hedqvist 1962 ". 



Cratomus nigripes Walker. Walker published Stephens' manuscript description 

 of nigripes, based upon specimens which Stephens had captured in his garden at 

 the Hermitage, South Lambeth, London. Stephens' material of Cratomus is in 

 BM(NH) and comprises 5 specimens. Three are labelled as having stood under 

 the name megacephalus in his collection. The other two (males) are labelled 

 " Cratomus ater. stood under this name in Stephens' collection ". One of these 

 males, which is card-pointed and staged on a strip of pith, also bears a manuscript 

 label " ater " ; I designate this specimen LECTOTYPE of Cratomus nigripes 

 Walker, as it agrees well enough with the description. It has subhy aline wings, 

 whilst the legs are dark enough to be described as " black ", they are black with 

 the tarsi fuscous, only the base of the first segment of the mid and hind tarsi being 

 pale. The name might well have been altered from ater to nigripes before 

 publication.
