PTEROMALIDAE OF N.W. EUROPE 73 



Eunotus (Eunotus) ? areolatus (Ratzeburg) 



? Tridymus {Tvitypus) areolatus Ratzeburg, 1848 : 227, $, figs, [not numbered]. 

 Eunotus cretaceus Forster, 1856 : 66 [nee Walker, 1834]. 

 Eunotus obscurus Masi, 1931 : 482, <J $. 



Type material. Tridymus areolatus Ratzeburg. Types presumed lost. Ratze- 

 burg's description and figures apply very well to the present species. 



Eunotus obscurus Masi. Syntypes in Museum Nationale d'Histoire Naturelle, 

 Paris, coll. Giraud (two labelled " Megapelte obscura var." and " ex Cocco crataegi 

 crista galli ") ; and in Naturhistorisches Museum, Vienna, coll. Forster (3 $ labelled 

 "Aachen, Forster" and "Eunotus cretaceus det. Forster"; 1 $ labelled "Ex 

 Coccus vitis "). 



France, Germany, Italy, Spain. 



Biology. Reared in Italy by Masi from Parthenolecanium (= Lecanium) persicae 

 (F.) ; Masi also mentions several specimens collected by earlier authors and labelled 

 with the names of other hosts, the identity of which is rather uncertain (recorded 

 under Eunotus obscurus). 



Eunotus (Eunotus) nigriclavis Forster 



Eunotus nigriclavis Forster, 1856 : 66 [$]. 

 Eunotus nigriclavis Forster ; Masi, 193 1 : 431, ?. 



Type material. Holotype $ (lacking head) in Forster coll., Naturhistorisches 

 Museum, Vienna ; labelled " Eun. nigriclavis Forster — Type " and " Aachen, 

 Forster ". 



Germany, Italy. May also occur in England but this is not certain (see 

 Boucek, 1965^ : 83). 

 Biology. Unknown. 



Eunotus (Eunotus) acutus Kurdjumov 



Eunotus acutus Kurdjumov, 1912 : 330-331, fig. I, A-D, o" $• 

 Eunotus acutus Kurdjumov ; Masi, 1931 : 430-431. 



Type material. Syntypes, 5 $ and 1 <J reared from Eriococcus greeni Newstead on 

 Agropyron repens at Poltava Experimental Station, Ukraine, Russia ; location of 

 types not known to the writer. 



This may be a valid species, but the question can only be settled by an examina- 

 tion of the types. According to Kurdjumov's description, the marginal vein is only 

 slightly longer than the stigmal vein ; in this respect acutus resembles nigriclavis 

 (Forster) more than any other European species of Eunotus {Eunotus). Masi (1931 : 

 431) examined two males, collected in Austria by Ruschka, which agreed with the 

 description of acutus ; from this he considered that acutus was similar to obscurus 

 Masi, but differing in its shorter marginal vein and the form of the propodeum.
