BRITISH ICHNEUMONS. 24I 



apically rufescent ; gastrocaeli minute but distinct. Legs red ; anterior 

 trochanters, and in ^ coxae, flavous ; <? with hind coxae black and hind 

 femora and tibiae fuscous towards their apices. Stigma red ; tegulae 

 white. Length, 5-7 mm. 



If. iniermedius, Wesm., is now considered a $ variety of this species, 

 which has the body very finely and closely punctate throughout, and 

 diflers from it in its puncturation being much less close, rendering it more 

 strongly nitidulous, the thorax is entirely black and more cylindrical Avith 

 the mesonotum less convex, the impression on the mesopleurae beneath 

 the hind wings is deeper and the central segments are more or less 

 infuscate. 



Bridgman took the type form, at Earlham, near Norwich, in August, 

 1881, and the var., at Eaton, in the same neighbourhood ; the latter is 

 recorded by Bignell, from Bickleigh, in August, and Exeter, early in Sep- 

 tember. It is a local species on the Continent, and has not been bred. 



3. furunculus, Wesm. 



HerpeUomits funincitlus, Wesm. Nouv. iNIt-m. Ac. Brux. 1844, p. 171 ; Berth. Ann. 

 Soc. Fr. 1896, p. 348, ? . 



This species will probably prove to be no more than a variety of the 

 preceding, from which it differs in the broadly and deeply canaliculate 

 petiolar area ; the slightly longer and more slender petiole, and somewhat 

 more incrassate legs, of which all the coxae are red. 



Bridgman says (Trans. Ent. Soc. 18S3, p. 140) he took a specimen, 

 appearing to appertain to this species, in which the legs were decidedly 

 thinner than those of H. ititermedius. He expressed some doubt, however, 

 and, until this be cleared up, H. furi/nci/liis, which is only recorded else- 

 where from the vicinity of Brussels, has but a poor claim to incorporation 

 in our fauna, in spite of his record of its occurrence at Earlham, Eaton and 

 IMousehold, in August and September (Trans. Norf. Nat. Soc. 1893, p. 610).
