Type material. For synonymy and designation of lectotypes for most of the 

 above Walker species, see Graham (1956& : 248). Species for which lectotypes 

 were not selected are : 



Pteromalus saptine Walker. Syntypes, 2 $ ; LECTOTYPE, the second 

 specimen, bearing a circular label " 38. 7. 12. 216 ". It may be a slightly aberrant 

 male of helvipes. 



Pteromalus peregrinus Forster. Syntypes, 2 $. LECTOTYPE labelled " Pt. 

 peregrinus Forster Type " and, in Forster's handwriting, " peregrinus m.". 



Pteromalus lethargicus Forster. One female, LECTOTYPE ; labelled " Collect. 

 G. Mayr " ; " Pt. lethargicus Forster Type " ; and, in Forster's handwriting, 

 " lethargicus m.". 



Pteromalus quaesitus Forster. Syntypes, 2 $. LECTOTYPE labelled " Collect. 

 G. Mayr " ; " Pt. quaesitus Forster Type " ; and, in Forster's handwriting, 

 " quaesitus m.". 



Pteromalus delectus Forster. One female which agrees only poorly with the 

 description but is accepted as TYPE ; it is labelled, in Forster's handwriting, 

 " Pteromalus delectus nob. det. Forst.". 



Pteromalus lebadeia Walker. One female, LECTOTYPE, bearing a Waterhouse 

 label. 



The following notes on the female of helvipes are intended to supplement the 

 redescription given in Delucchi & Graham (1956 : 573-574) : 



Length 1-4-2-9 mm. Colour of head and thorax usually greenish, but varying from blue 

 through green and bronze-green to coppery bronze ; pale parts of legs tending to be pale or 

 yellowish testaceous, occasionally fulvous ; femora often more or less infuscate, sometimes 

 mainly so ; tibiae sometimes brownish or fuscous medially. POL 1-2-1-4 times OOL. Mar- 

 ginal vein 1-3-1-5 times as long as the stigmal vein ; postmarginal vein about as long as, or a 

 little longer than, the marginal. 



Britain, Ireland, Sweden, Norway, Germany, Switzerland. One of the 

 commonest species of the genus in Britain. 



Biology. Recorded as a parasite of Brachonyx pineti Payk. in Norway (Secretariat, 

 etc., 1957 : 321, 324). I have seen a female obtained from an inflorescence of 

 Trifolium sp. in southern England, possibly parasitizing one of the " Clover weevils " 

 (Apion sp.). Imagines June-October, females then over-wintering in dry situations, 

 particularly amongst the foliage of Cupressus and other coniferous trees. 



Trichomalus tenellus (Walker) 



Amblymerus tenellus Walker, 1834 : 348, $. 

 Pteromalus saturatus Walker, 1835 : 495, $.
