242 BRITISH ICHNEUMONS. 



jnfuscate ; post-petiole red, aciculate, a little dilated and centrally gla- 

 brous ; gastrocaeli wanting, but thyridii distinct. Legs red ; coxae 

 nigrescent, those of $ mainly white. Stigma and tegulae piceous ; radix 

 whitish. Length, 5-6 mm. 



The typical ^ has the scutellum flavous, with the basal segment black, 

 the second black with a red margin, the third red witli a nigrescent dorsal 

 mark, and the following red, the ultimate being infuscate ; /. xanihops has 

 two apical confluent white dots on the scutellum, and the abdomen black 

 with the post-petiole, second, third and fourth segments marked with cas- 

 taneous ; I. facialis has the scutellum black, with the three basal segments, 

 except the petiole, red, the fourth being entirely black or in part red ; 

 I. pusillaior i\^o has the scutellum black, but with all the segments red- 

 margined. 



Scarce, taken near London, in July (Stephens) ; Mr. F. C. Adams has 

 been good enough to send me two females of this distinct species, taken 

 at Lyndhurst, in the New Forest, in May and June; it is probably local, 

 having a restricted continental range, from Belgium to Sweden, and has 

 not been bred. 



5. distinctus, Bridg. 



Herpestomus disiinctiis, Bridg. Trans. Ent. Soc. 1SS7, p. 362 ; Berth. Ann. Soc. Fr. 

 1896, p. 349, 9 . 



This species would appear to be very closely allied to the last-described, 

 from which it differs in the following particulars : — Head transverse, 

 scarcely narrowed behind the eyes, impunclate, entirely black ; apex of 

 clypeus broadly rounded. Antennae somewhat clavate. Thorax immacu- 

 late ; notauli distinct ; costulae sub-complete. Basal abdominal segment 

 somewhat irregularly and coarsely aciculate, with its apex nitidulous. 

 Apical half of hind femora, apex and extreme base of hind tibiae, infus- 

 cate. Length, 5 mm. 



Bridgman described this species from a single female, taken by Mr. G. 

 C. Champion, at Caterham. The type is probably in the former's col- 

 lection, in the Norwich Castle Museum ; it is unknown on the Continent. 



PHAEOGENES, IVes^nnel} 



Wesm. Nouv. Mum. Ac. Brux. 1S44, p. 166. 



Head often transverse, and broader than thorax ; clypeus sub-glabrous, 

 not abruptly depressed apically ; epistoma short, distinctly discreted from 

 clypeus by a transverse impression ; mandibles of nearly equal breadth 

 from base to apex, their teeth of nearly ecjual length, the lower being 

 slightly the shorter. Antennae filiform or a little attenuate apically ; scape 

 rarely inflated or deeply excised at apex. ISIetalhorax not posteriorly pro- 

 duced. Scutellum almost invariably black. Gastrocaeli transverse-linear, 

 sub-confluent centrally ; thyridii always distinct, those of $ somewhat 

 remote from base of second segment. Legs somewhat stout ; hind coxae 



1 Ichncumnn rufator, Stc. 111. M. vii. 2or, c? , is a Phaeogcncs, as his type in the British Museum 

 indicates, but I do not know to which of the recognised species it belongs. Stephens took it about 

 London, in June, and Parfitt boldly records it from Hatherleigh, in Devon.
