Type material. Pteromalus affinis. Lectotype designated by Graham (1956ft : 

 250). In that paper I synonymized affinis with apertus (Walker) ; but I now 

 consider that the lectotype of affinis to be a female of inscitus having the legs paler 

 than usual. Actually none of the syntypes of affinis agrees perfectly with the 

 description ; that designated as lectotype agrees best, although it has the femora 

 darkened ; they were, however, partly hidden beneath the thorax and their colour 

 could have been mistaken. 



Pteromalus inscitus Walker, P. tristis Walker, and P. microcerus Walker. Lecto- 

 types designated by Graham (19566 : 249). 



Pteromalus deiochus Walker. Syntypes, 3 $ ; LECTOTYPE, the third specimen, 

 bearing a Waterhouse label. 



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

 G. Mayr " and " Pt. reconditus Forster Type ". 



Pteromalus diachymatis Ratzeburg and P. orchestis Ratzeburg. Types formerly in 

 Ratzeburg collection, Eberswalde, now presumed destroyed. P. orchestis was 

 transferred to Habrocytus by Kurdjumov (1913 : 20). Ruschka (1927 : 14) stated 

 that, through Professor Eckstein, then in charge of Ratzeburg's collection, he had 

 compared the types of diachymatis and orchestis and considered them to be the 

 sexes of one species. He also corrected Kurdjumov, who had placed orchestis in 

 Habrocytus, pointing out that it had 4 teeth in both mandibles and a thickly pilose 

 propodeal callus, characters which associated it with Trichomalus. Ratzeburg's 

 original material of both diachymatis and orchestis was reared from " Orchestes 

 viminalis " [=Rhynchaenus quercus (L.)]. This data, together with Ratzeburg's 

 descriptions and the information later supplied by Ruschka, leave no doubt that his 

 two species were the same as inscitus (Walker). 



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

 label.
