Type material. Miscogaster nicaee. None found. The description answers so 

 well to the present species (especially the statements that the head is much broader 

 than the thorax, antennae clavate and very slender, wings narrow and short) that I 

 am sure it is interpreted correctly. 



Pteromalus zagreus Walker. Syntypes, 2 $. LECTOTYPE, the second specimen 

 (lacking gaster), bearing a Waterhouse label. 



Meraporus (Leptomeraporus) tenuicornis Graham. Holotype $, Ireland, Co. 

 Dublin, North Bull, 11. v. 1949 (Stelfox), in coll. Graham. 



Megorismus aon Walker is represented in his collection by a male specimen, but 

 it was never described. 



Britain, Ireland, Czechoslovakia, Hungary. 



Biology. Bailey (i960 : 40) recorded nicaee [under the name of tenuicornis 

 Graham] as a parasite of Tetramesa linearis (Walker) and Eurytoma flavimana 

 Boh. in the galls produced by the former on stems of Agropyron repens (L.) Beauv. ; 

 he also (ibid., fig. 1) figured the larva of Leptomeraporus tenuicornis Graham 

 (=nicaee Walker). Erdos (1961) figured both sexes of tenuicornis and stated that 

 he had reared it from galls of Tetramesa hordei (Harr.) on Agropyron repens L. 

 Imagines appear in May- July and September. 



LAMPOTERMA Graham 



Metastenus Thomson, 1876a : 205 [nee Walker, 1834]. 



Lampoterma Graham, 1956ft : 256. Type-species : Metastenus viridis Thomson, 1876a, by ori- 

 ginal designation. 



This genus is not very distinct from Stinoplus Thomson, of which it may eventually 

 be regarded as a subgenus.
