Grypocentrus | BRITISH ICHNEUMONS. 313 

radix and tegulae of g flavous; stigma large and triangular, areolet want- 
ing; radial cell short, subtrapeziform and apically reflexed; nervellus 
intercepted below its centre. Length, 4—5 mm. 
At once known from the following species by its larger size, total lack 
of alar areolet and the entirely red anus. 
It was described from Germany and Boheman took the 9 in Sweden ; 
subsequently Brischke bred both sexes from Fenusa larvae feeding on 
Geum, the Avens, in Prussia and Gaulle records it from France. With us 
it was introduced by Bridgman (Trans. Ent. Soc. 1887, p. 373) on the 
strength of specimens recently taken by Dr. Capron about Shere in Surrey. 
These seven examples are now in my collection, together with females I 
captured in the middle of August, 1902, in a greenhouse at Ryde, Isle of 
Wight, and among osiers at Barton Mills in June; W. Ollis has taken it 
at Hastings in July.
