PTEROMALIDAE OF N.W. EUROPE 825 



Type material. 



Pterotnalus distinguendus Forster. Syntypes presumably in Forster coll., 

 Naturhistorisches Museum, Vienna (not seen) ; I have examined some Forster 

 specimens, determined by him as distinguendus, in the Westwood collection in 

 Oxford. 



Pteromalus calamis Walker. Syntypes, n specimens ; LECTOTYPE, the first 

 one, a male (Type Hym. 5.708) labelled " Madeira, Wollaston " and " Pteromalus 

 calamis ". 



Pteromalus oryzinus Rondani. Type in Museum " La Specola ", Florence, 

 according to Delucchi (1955a : 174) who stated it to be the same as distinguendus. 



Meraporus utibilis Tucker. Type $ (U.S.A., Texas, Piano) in U.S.N.M. (not 

 seen). The species was synonymized with L. distinguendus by Gahan (1921), who 

 considered the type of utibilis to be a rather small and poorly developed specimen 

 of distinguendus. 



Cosmopolitan. 



Biology. Parasite of beetles associated with stored products, e.g. Calandra 

 (=Sitophilus) oryzae (L.), Lasioderma serricorne (F.) (Anobiidae), Bruchus brachialis 

 Fahr. (Briichidae). A detailed list of references to its hosts is given by Peck (1963). 

 Occasionally the species is captured in open country.

Type material. Kurdjumov (1913) stated that he had seen " the type " in 

 Naturhistorisches Museum, Vienna ; Ruschka (1921 : 464-465) also mentioned 

 having examined the types in that museum. According to Ent. Tidskr. (1883 : 22 3)» 

 Moller presented specimens of puncticollis to the Entomological Society of Stockholm ; 

 I am not aware of the present location of these. It will be necessary to re-examine 

 all the extant syntypes and to select a lectotype. Meanwhile the status of 

 puncticollis is rather doubtful. Kurdjumov (1913) transferred it to Lariophagus 

 and gave some brief notes on the specimen which he considered to be the type. 

 Waterston (1921) referred to Kurdjumov's notes, and also redescribed and figured 

 puncticollis from three other females which he considered to belong to that species ; 

 one of them is now in the BM(NH) and has been examined by me. According 

 to Waterston (1921 : 9) puncticollis differs from distinguendus in its larger size 

 [actual dimensions not mentioned], more distinct and numerous setigerous punctures 

 of the mesoscutum, more numerous bristles on stigmal vein [wrongly termed 

 " marginal vein " on p. 9], and structure of the propodeum, the front part of the 

 latter being divided into four rectangular cells. The distinctions enumerated by 

 Waterston do not appear at all obvious to me. One of the females which he
