BRITISH ICHNEUMONS, 255 



hibernation, in November ; and Bignell found it early in August, at Wide- 

 well and Plym Bridge, in Devon. Berthoumieu records it only from 

 Bekium, where Wesmael first took it near Brussels. 



i6. infimus, IVesm. 



Phaeogenes in/uniis, Wesm. Nouv, Mi'm. Ac. Brux. 1S44, p. 191 ; Thorns. O. E. xv. 

 1653; Berth. Ann. Soc. Fr. 1S96, p. 377, 9. 



Head stout ; frons strongly punctate ; mandibles piceous ; palpi fulvous. 

 Antennal flagellum basally red. Thorax sub-ovate, black ; areola sub- 

 quadrate ; costulae fine ; petiolar area not strongly impressed. Abdomen 

 with second segment except its centre, the third, and base of fourth, red ; 

 post-petiole sub-aciculate ; the remaining segments somewhat strongly 

 punctate and shining. Legs red ; hind femora apically sub-fuscous ; hind 

 coxae black, with an elevated, oblique, sub-obsolete line. Tegulae and 

 stigma black ; radix white. Length, 5 mm. 



The red anterior coxae will serve to differentiate this species ; the acicu- 

 lation of the post-petiole is not always present in my examples, and would 

 appear to be an inconstant character. 



This species, which has not before been noticed in Britain, is probably 

 one of our commonest kinds, since I have beaten it freely from the 

 branches of large Finns sylvestris in Bentley Woods, near Ipswich, 

 throughout April during several years ; it was probably just emerging from 

 hibernation. 



17. eques, Wesvi. 



Phaeogenes eqiies, Wesm. Nouv. M6m. Ac. Brux. 1844, p. 194 ; Thorns. O. E. xv. 

 1654 ; Berth. Ann. Soc. Yx. 1S96, p. 379, ? . 



Black. Mandibles and pronotum sometimes rufescent. Antennae tri- 

 coloured ; scape in part black. Abdomen nitidulous, distinctly punctate ; 

 segments two to four, and often apex of first, red ; post-petiole aciculate 

 before its glabrous apex. Legs red ; apex of hind femora and tibiae, with 

 often the base of the latter, infuscate ; coxae with carinae sub-dentately 

 elevated obtusely towards their apex. Tegulae, radix and stigma tes- 

 taceous. Length, 6| mm. 



This may be known from the last four species by its laterally sub-sinuate 

 clypeus and the distinct aciculations before the sub-elevated coxal carinae. 

 It is more likely to be confused with F. isc/iiome/inus, with which it has 

 the somewhat broad vertex, laterally sub-sinuate clypeus, pale tegulae, 

 partly infuscate hind coxae and tricoloured flagellum in common ; but it 

 differs therefrom in its more coarctate body, shorter and stouter flagellum, 

 dull and irregularly punctate frons, absent notauli and more shortly pro- 

 duced coxal carinae. 



I was so fortunate as to beat an example of this species, which has not 

 hitherto been noticed in Britain, from young birch trees in Assington 

 Thicks, in Suffolk, upon i6th May, 1902. It is found in France, Germany 

 and Sweden, but has not been bred.
