PTEROMALIDAE OF N.W. EUROPE 439 



Thomson, however (1878 : 59) mentioned that the fore wings of his specimens had 

 a discal cloud (" umbra longitudinali subfumata sub radio et stigmate "). Masi 

 (1922c) said that Ruschka's specimens of scabriculus had a brownish yellow discal 

 cloud. Szelenyi (1941) distinguished scabriculus (Nees) from meridionalis (Masi) 

 and his own species globulariae by the presence of a distinct cloud on the wing of 

 scabriculus and its absence in the other species. I have seen specimens which 

 agree with the redescriptions of scabriculus given by Thomson and Masi except 

 that they have the fore wings immaculate. Probably, therefore, this character 

 is variable and not diagnostic. Masi (1922c) stated that females of his meridionalis 

 differed from those identified as scabriculus by Ruschka in having the head a little 

 broader relative to the breadth of the thorax, as well as in some other details of 

 colour and structure. Possibly the distinguishing characters given by Masi (with 

 the exception of the presence or absence of a cloud on the fore wing) have specific 

 value ; at all events, they seem to be borne out fairly well in the material I have 

 seen. 



Sweden, Germany ; recorded also from U.S.S.R. and Italy, but this material 

 has not been examined ; released in Canada but not established, according to 

 Peck (1963). 



Biology. The species was recorded as a parasite of Cephus pygmaeus L. and 

 Trachelus tabidus F. (Hym., Tenthredinoidea) on cereals in U.S.S.R., by Borodin 

 (1915, Choziajstvo Kiev, nos. 33-36, passim) ; and as a parasite of Lixus junci 

 Boh. (Col., Curculionidae) on sugar-beet in Italy, by Menozzi (1936). The material 

 upon which these records were based is not traceable, and confirmation is desirable. 



Norbanus meridionalis (Masi) comb. n.

Type material. Syntypes, Italy, Liguria, 1 $ ; Isle of Giglio, 36 $ captured 

 June-August 1901 and 6 <$ captured in May 1901 and July 1902, in Museo Civico di 

 Storia Naturale, Genoa (not seen). 



Masi originally recorded his material as scabricula, but in 1922 decided that it 

 represented a distinct species after comparing it with specimens determined by 

 Ruschka as Picroscytus scabriculus. For a discussion of the differences between 

 scabricula and meridionalis see Masi (1922c).
