Bakkendorf (1955) is not that species, but may be Sceptrothelys deione (Walker). 

 That recorded from England as a parasite of Coleophora laricella (Hbn.) under the 

 name Eurydinota laricinellae (Ratzeburg), by Ferriere (in Thorpe 1933 : 272, 289) 

 was probably not a Eurydinota, but may also have been Sceptrothelys deione. 

 Ratzeburg originally described laricinellae as a Pteromalus (1852 : 198), from the 

 same host, and there is nothing in his description which seems to contradict the 

 supposition that it is the same as deione.

Sceptrothelys grandiclava (Walker) ; Boucek, 1961 : 79. 



Type material. Pteromalus grandiclava Walker. Lectotype designated by 

 Graham (1956 : 91) ; it bears a Waterhouse label. The species was redescribed 

 in the same paper (1956 : 89-91). 



Pteromalus claviger Forster. Lectotype $ (not seen by the writer) selected by 

 Delucchi (1958a : 51) who stated it to be the same as grandiclava. 



Britain, Sweden, Germany, Czechoslovakia. The record of "Pteromalus 

 claviger Forst." from Hungary by Erdos (1948 : 46) evidently refers to some other 

 species than grandiclava (Walker) . 



Biology. Unknown. In Britain the species occurs in open situations (chiefly 

 rough grassland). Imagines June-August. 



Sceptrothelys intermedia sp. n. 



(Text-fig. 366) 

 Sceptrothelys grandiclava (Walker) Graham ; Markkula, i960 : 227 [nee Walker]. 



$. Head and thorax olive-green, or brighter green to greenish blue ; gaster with strong 

 metallic reflections, especially upon its basal tergite. Mandibles testaceous with reddish 

 teeth. Antennal scape bright testaceous, its distal part more or less infuscate ; pedicellus 

 and flagellum fuscous. Coxae concolorous with the thorax ; legs otherwise bright or reddish 

 testaceous ; the knees, tips of the tibiae, and bases of the tarsi, paler ; tarsi distally, the fore 

 tarsi sometimes wholly, brownish. Tegulae bright or reddish testaceous ; wings subhyaline, 

 venation testaceous. Length 1-5 to 2-2 mm. 



Structurally this species closely resembles grandiclava (Walker) a redescription of which was 

 given earlier (Graham, 1956 : 89). It differs from grandiclava as follows : 



The antennal scape is slightly longer, reaching level with the lower edge of the median ocellus 

 or somewhat above this level. The flagellum (Text-fig. 366) is rather less clavate ; the distal 

 funicular segments are less strongly transverse, the sixth being about 1 -5 times (instead of about 

 twice) as broad as long ; the clava is relatively shorter, its length about equalling the combined 

 lengths of the three or four preceding funicular segments ; ventrally the clava has a shorter 

 area of micropilosity, which extends from the tip about three quarters of the distance towards 

 the base, whilst the apical margin of the first claval segment is less strongly excised than in 

 grandiclava. The propodeum has a slightly larger nucha, whose length is about half, instead 

 of one third or hardly more, the length of the sclerite.
