Pteromalus ornytus Walker. Syntypes, 2 <$. LECTOTYPE, the first specimen ; 

 Waterhouse label. 



Pteromalus brassicae Curtis and P. pontiae Curtis. Types probably in Curtis 

 collection, National Museum of Victoria, Melbourne, Australia (not seen). Both 

 species were later synonymized with puparum (Linnaeus) by Curtis himself (i860 : 

 100, footnote). These are not nomina nuda, as supposed by Sherborn (1924, 1929). 



Pteromalus orinus Walker. One $, LECTOTYPE, bearing a Waterhouse label ; 

 a very small specimen with antennal funicular segments unusually short. 



Pteromalus nigricans Walker. Syntypes, 2 $ mounted on the same card (Type 

 Hym. 5. 713) ; LECTOTYPE, the left-hand specimen. Labels " Madeira 

 Wollaston " and (in Walker's handwriting) " Pteromalus nigricans ". 



Pteromalus pieridis Provancher. Lectotype, Canada, Quebec, in Museum of the 

 Province of Quebec (not seen) ; the species was placed in synonymy with puparum 

 by Peck {in Muesebeck et al., 1951 : 561). 



Europe, Madeira, Asia, North Africa, Canada, U.S.A. ; New Zealand 

 (introduced). 



Biology. Well known as a parasite of the pupae of Lepidoptera, particularly 

 Rhopalocera ; in Europe most often on Pieris spp., Nymphalis spp., also on Papilio 

 machaon L., Aglais urticae (L.), Pyrameis cardui (L.), Vanessa atalanta (L.) and 

 other butterflies. Peck in Muesebeck, et al. (1951) and Peck (1963) cited records of 

 rearings from species belonging to other families of Lepidoptera ; from Ichneu- 

 monidae, Braconidae, and in one case from the Chalcidoid Dibrachys cavus (Walker), 

 in these instances as a hyperparasite ; and from species of Vespidae and Sphecidae. 

 In Europe imagines may be found in the field May-October.

Type material. Pteromalus bifoveolatus Forster. Type <$ (not seen by the 

 writer) in coll. Forster, Vienna, labelled with the number 103 (see Delucchi, 1958a : 



53)- 



Pteromalus saturniae Rudow. Types ? in coll. Rudow, Phyletischen Museum 

 der Friedrich-Schiller-Universitat, Jena. Boucek (1961 : 94) suggested that 

 saturniae might be the same as bifoveolatus (Forster). 



Heterolaccus mauritanicus Masi. Syntypes, Morocco, Rabat, 3 <$ and 3 $, reared 

 from Centra (= Dicranura) vinula (L.), in Museo Civico di Storia Naturale, Genoa. 

 The species was synonymized with bifoveolatus (Forster) by Delucchi (1958a : 

 53-54)- 



Britain, Continental Europe (probably widely distributed), ? Sicily ; North 

 Africa.
