PTEROMALIDAE OF N.W. EUROPE 197 



two males (but the female is not a syntype, though possibly the type of Cyrtogaster 

 scotica Walker, q.v.). LECTOTYPE, the second male, bearing a Waterhouse label. 

 Lamprotatus niger Delucchi. Type 9. Lower Austria, Puchberg in Wienerwald, 

 13.viii.1915, in Naturhistorisches Museum, Vienna, not seen, but the description 

 suggests that it may be the same as scoticum. 



Britain, Ireland ; ? Austria. In the British Isles the species is very local ; 

 I have captured it on coastal sand dunes, also on moorland in inland situations. 

 Biology. Unknown. Imagines June-August. 



Seladerma genale (Thomson) comb. n. 



Lamprotatus genalis Thomson, 1876a : 231, $. 



Type material. One female (lacking the gaster), the holotype ; labelled " Sm " 

 [Smaland], " Bhn " [Boheman] and " genalis Ths ". 



Sweden : Smaland (holotype $). I have taken a male Seladerma in Britain which 

 may be that of genale and have mentioned its characters in my key to males (q.v.).

 scoticum (Walker).
