Scotland : West Inverness, Isle of Rhum, Papadil, i $, 4.vii.i962 (P. Wormell). 



Czechoslovakia : Bohemia, Stechovice near Prague, 2 $, 20.vii.1957, on a stump 

 (L. Masner) ; Velky Vfestov, 1 $, vi.1954 (Boucek) ; Eastern Slovakia, Zadiel, 

 1 $, vi.1956 (L. Masner). 



Western Germany : Miinchen, 1 $, 14.V.1961 (Bachmeier). Paratypes in the 

 Graham collection, in that of the Manchester Museum and in that of the National 

 Museum, Prague. 



This species is near stenogaster (Walker) but may be distinguished from it and 

 from the other described species by its longer gaster, and especially by the form 

 and colour of the last tergite ; and by the basal cell of the fore wing, which is closed 

 below. 



Biology. Unknown. 



Holcaeus stenogaster (Walker) comb. n.

? Pteromalus Cabades Walker, 1839 : 264, <$.

Type material (all Walker types bear a Waterhouse label). 



Pteromalus stenogaster Walker. Syntypes, 2 $. LECTOTYPE, the second 

 specimen ; Waterhouse label " Hetroxys stenogaster Walker ". 



Pteromalus styrus Walker. One male, LECTOTYPE. 



Pteromalus cabades Walker. Syntypes, 2 <$. LECTOTYPE labelled " 38. 7. 12. 

 191 ". 



Gastrancistrus amnisos Walker. One male, LECTOTYPE, with a printed label 

 " GASTRANCISTRUS Amnisos ". 



Etroxys longicauda Thomson. Syntypes on 7 pins. The first pin bears a male 

 and a female, labelled " Hg " [Halsingborg] on a pale green label, also " longicauda 

 Ths." The female is designated LECTOTYPE. 



I consider styrus Walker and cabades Walker to be probably the males of stenogaster 

 (I am not absolutely certain of the distinctions between the males of stenogaster 

 and compressus). 



Widely distributed in Europe and fairly common. 



Biology. Unknown. On one occasion I captured a female upon a bracket-fungus 

 (Polyporus sp.) but there may be no particular significance about this. Imagines 

 Apr.-July.
