36 BRITISH ICHNEUMONS. [Microcryffiis. 



basal segment. Legs of 9 entirely red, or with the apices of the hind 

 femora, and more rarely of their tibiae, infuscate ; of ^ with the anterior 

 coxae and trochanters wholly white, hind ones with the coxae basally 

 black and the apices of their femora, tibiae, and of the tarsal joints, infus- 

 cate. Wings of both sexes normal, somewhat clouded, ? with outer 

 nervure of the areolet sub-obsolete ; radix and tegulae while, latter in ? 

 dark ferrugineous. Length, 5-7 mm. 



The sub-quadrituberculate metathorax allies this species with those of 

 Rhembobius ; the petiolar area is nearly parallel-sided, and reaches far 

 beyond the centre of the metathorax. From all the other species of this 

 genus it differs in its closely punctate frons, deeply discreted clypeus, the 

 extent of red coloration of the fully winged ? , and the entirely white 6 

 anterior coxae and pale antennae. 



On the Continent it is still known by its later female name. 



It occurs throughout central and northern Europe, where it is probably 

 not rare at the roots of Jitucns biifonius in damp places, in which situation 

 I took several females, together with Heniiteks varicornis, towards the end 

 of July, 1904. Stephens says it was not common near London, in June ; 

 and Bignell has sent it to me from Devon, and Thornley from Retford. I 

 also possess a single male, captured by Col. Yerbury at Pembridge, on 

 15th July, 1902 ; and have seen females taken by Evans at Midcalder, in 

 Midlothian ; and Boness, in Linlithgow in June.
