Catalaccus cavigena Thomson. Syntypes, 3 $. Lectotype labelled " Sm. Bhn " 

 [Smaland, Boheman] and " cavigena Ths ". 



Merisoides crassiceps Masi. Holotype $, Italy, Catanzaro, from the cocoon of an 

 Ichneumonid on Inula viscosa, presumably in Museo Civico di Storia Naturale, 

 Genoa. Masi (191 1 : fig. 3) shows the antenna of crassiceps as having 3 anelli and 

 5 funicular segments, whereas all the females of ater that I have seen have 2 anelli 

 and 6 funicular segments ; crassiceps may, however, have been a very aberrant 

 female of ater. 



Britain, Sweden, Germany, Czechoslovakia. 



Biology. Reared in Sweden as a hyperparasite of an unknown host through 

 Apanteles globatus (L.) by A. Jansson (1952a : 180) ; also recorded as a parasite of 

 Apanteles spurius Wesm. in Germany (Secretariat, etc., 1957 : 320, 325), and of 

 Rhynchaenus salicis L. in Italy (ibid., 1963 : 342, 357). Otten (1940 : 185) 

 recorded having reared it in Germany, often from Apanteles congestus Nees and 

 Gelis sp., and twice from Chamaepora [=Apatele] rumicis (L.) (Lep., Noctuidae). 

 Imagines in April, May, July and August. 



ERYTHROMALUS Graham 



Erythromalus Graham, 1956 : 83. Type-species : Pteromalus nubilipennis Walker, 1835, by 

 original designation. 



The two species included here are somewhat variable, particularly in the relative 

 length of the gaster in the female, and the pilosity of the basal cell of the fore wing ; 

 but I believe they are distinct. 



Key to European Species 

 (Females) 



1 Antenna with combined length of pedicellus and flagellum equal to or slightly greater 

 than breadth of head. Basal cell of fore wing (Text-fig. 350) having at most its 

 distal half pilose. Gaster slightly longer than head plus thorax, 1 -9 to 2-2 times as 

 long as broad (Text-fig. 349) .... nubilipennis (Walker) (p. 468) 



- Antenna with combined length of pedicellus and flagellum slightly to quite distinctly 

 less than breadth of head. Basal cell of fore wing having at least its distal two 

 thirds pilose, sometimes wholly pilose except just at the base. Gaster shorter 

 than, or at most as long as, head plus thorax, 1 -65 to 1 -9 times as long as broad 



rufiventris (Walker) (p. 470) 



The males of Erythromalus are not keyed because that of nubilipennis has not 

 definitely been identified.
