248 BRITISH ICHNEUMONS. 



4. suspicax, PVesm. 



Phaeogenes suspicax, Wesm. Nouv. l\I('m. Ac. Brux. 1844, p. 200, i 9 ; Brisch. Schr. 

 Nat. Ges. Danz. 1S78, n. 6, p. 57, ? ; P-ridg. Trans. Ent. Soc. 1881, p. 147, i ; Thoms. 

 O. E. XV. 1651 ; Berth. Ann. Soc. Fr. 1896, p. 382, i ?. Prosciis suspicax, Holmgr. 

 Ichn. Suec. iii. 422, i 9 . 



Black ; antennae brown, sub-annulated with red ; areola longer than 

 broad ; second and third abdominal segments often mostly red ; legs 

 variegated with red and fuscous ; tegulae often white ; $ with moulii, 

 clypeus and face sulphureous, and the anterior coxae and trochanters 

 apically white. Length, 4-5 mm. 



This species so closely resembles the last-described in structure as to 

 need no detailed description ; it may instantly be known therefrom by 

 its finely punctate, convex and shining frons, by its excavate and very 

 indistinctly discreted petiolar area, transverse areola and small size. 



Scotland (Bridgman) ; captured at Bickleigh, in Devon, nth August 

 (Bignell). Probably mixed with P. cep/in/ofes, in Britain ; elsewhere it is 

 only noted from Sweden, Germany and Brussels. Ratzeburg (Ichn. d. 

 Forst. iii. 167) was almost certainly in error in supposing Brischke, who 

 makes no reference to the fact in his " Ichneumoniden der Provinzen 

 West- und Ost- Preussen," bred this species, from burrows of Saperda 

 popJilnea, which lives in the twigs of Popuhis treinula (cf. Diadroinus siib- 

 iilicornis, post). 



5. acutus, Grav. 



Ichneumon acutus, Gr. I. E. i. 598 ; cf. Wesm. !\Iem. couron. Ac. Belg. 1859, p. 74. 

 Phaeogenes acutus, Bridg. -Fitch, Entom, 1882, p. 81; Berth. Ann. Soc. Fr. 1896, 

 p. 385> ? . 



Black. Antennae half length of body ; flagellum fuscous, with base 

 and two central joints ferrugineous. Thorax black with pronotum white. 

 Abdomen gradually narrowed from second to fifth segments ; the basal 

 hardly sub-foveolate ; second and third castaneous. Legs stout, black ; 

 anterior tarsi and most of their tibiae, base of all the femora, and inner 

 side of hind tibiae, ferrugineous. Wings a little clouded ; stigma fuscous, 

 radix and tegulae flavous. Length, 6-8 mm. 



This 5 has never been adequately described, and its present position 

 rests upon Wesmael's remark that it is allied to, but constitutes a very 

 different species from, his P. cephaloies. 



Gravenhorst took this little-known species, in June, in Germany ; it was 

 introduced as British, by Marshall, in his 1870 catalogue, but I failed to 

 notice it in his collection, nor am I aware of any indigenous records. 



6. mitigosus, Grav. 



Ichneumon mitigosus, Gr. I. E. i. 604, excl. var. i ; Ste. 111. M. vii. 204. i ; cf. 

 Wesm. M^m. couron. Ac. Belg. 1859, p. 74. Baeosemus viitigosus, Holmgr. Ichn.

 Fr. 1896, p. 385, <5 9 . 



Head sub-triangular, not buccate, slightly narrowed behind the eyes ; 

 mandibles moderately broad, with nearly equal teeth ; clypeus very closely 

 and finely punctate, apically broadly rounded, somewhat indistinctly dis- 

 creted ; cheeks not short. Antennae slightly attenuate apically ; scape a
