Pteromalus faustina Walker. One male, LECTOTYPE ; Waterhouse label. It 

 could well be the $ of nubilipennis. 



Britain, Ireland. 



Biology. Unknown. Imagines July-Aug. 



Erythromalus rufiventris (Walker) 



Pteromalus rufiventris Walker, 1835 : 192, $. 

 Pteromalus Empoclus Walker, 1839 : 214, <$. 

 Erythromalus rufiventris (Walker) Graham, 1956 : 86, $. 



Type material. Pteromalus rufiventris Walker. Lectotype $, designated by 

 Graham (1956 : 86). 



Pteromalus empoclus Walker. One male, designated LECTOTYPE (possibly 

 holotype), bearing a Waterhouse label. It definitely belongs to Erythromalus, and 

 probably to rufiventris (Walker).

Biology. Unknown. Imagines in September. 



ENDOMYCHOBIUS Ashmead 



Endomychobius Ashmead, 1896 : 227. Type-species : E. flavipes Ashmead, by monotypy. 

 Endomychobius Ashmead ; Schmiedeknecht, 1909 : 328, 330, 335. 

 Endomychobius Ashmead ; Ruschka, 1924 : 14-15. 



I have not seen the type-species of this genus but presume that it is correctly 

 identified here. The only European species, endomychi (Walker), was referred to 

 Endomychobius by Ruschka (1924 : 14).

 Endomychobius endomychi (Walker) Ruschka, 1924 : 14. 



Type material. Pteromalus endomychi Walker. Syntypes, 2 $. LECTOTYPE, 

 the second specimen, bearing a Waterhouse label ; it is evidently a Curtis specimen,

Pteromalus mazaces Walker. Syntypes, 2 $. One, bearing a Waterhouse label, 

 is selected as LECTOTYPE.
