Atractodes.\ BRITISH ICHNEUMONS. 25I 



Bridgman first noticed A. compressus in Britain, at A\'ro\ham in Norfulk, 

 in June, and Martineau has given me a female whicli he took at Selsley, in 

 May, 1893. 



7. subrufus, Grav. 



Tryphoii subrufus, Gr. I. I£. ii. 280, 6 . Atradotles alhoviuitus, Hal. Ann. Nat. 

 Hist. 1839, p. 119; Curt. B. E. 538; Thorns. O. E. x. 1024, <J 9 . ^ 



A black species with red palpi. Antennae of $ broadly white-banded, 

 basally testaceous and apically sub-incrassate, with the apical joint oblong, 

 and the penultimate half as long again as broad. Apophyses obtuse and 

 distinct. Abdomen centrally red, of 9 fusiform and apically compressed ; 

 the second segment with impressed lateral lines extending to the spiracles. 

 Legs red witli. the hind coxae black and their tarsi infuscate, becoming 

 apically paler ; tarsal claws stout, calcaria elongate. Areolet not externally 

 entire. Length, 4-6 mm. 



The obtuse apophyses and $ fiavidous flagellar band will easily dis- 

 tinguish this species. It is obviously closely allied to A. spiniger, Voll. 

 Tjd. V. Ent. 1878, p. 170, which is a J with tricoloured antennae. 



The synonymy here adopted is that entered in MS. in Marshall's private 

 copy of his 1872 Catalogue, and it certainly appears to be correct. 



Not common in Ireland (Haliday). Bignell's record of this species 

 from Devon is an error. 



8. piceicornis, Ilai. 



Atractodes piceicornis, Hal. Ann. Nat. Hist. 1839, p. 119, ?. A. JlavUoxa, Thorns. 

 O. E. X. 1024, i 9 . 



A black species with the head narrowed behind the sparsely pilose eyes, 

 and testaceous mandibles. Antennae of 9 somewhat stout a[)ically, with 

 the last joint oblong and the penultimate half as long again as broad. 

 Metathorax with the central area nitidulous and dilated in its centre. 

 Abdomen fusiform, centrally broadly testaceous and apically compressed ; 

 the second segment with lateral impressed lines reaching the spiracles. 

 Legs stout and roughly pubescent, testaceous with the hind coxae infus- 

 cate ; tarsal claws stout and calcaria elongate. Areolet not externally 

 entire. Length, 3-7 mm. 



This little-known species differs from A. exilis in its posteriorly con- 

 tracted head, pubescent legs and centrally explanate petiolar area. 



I have retained Haliday's name for this species, because the much 

 better defined A. Jlavicoxa has not been yet mentioned from Britain, and 

 his description is too short to definitely determine the synonymy. 



Eyrecourt in September (Haliday) ; Land's End district (Mar(iuand) ; I 

 took one female in Suffolk in 1894, and a second on An}^c/ii<i flowers at 

 Foxhall in the middle of Se[jteniber, 1903. 



1 A. varicornis, HoliriKr. Sv. Ak. Handl. 1858, n. 8, p. 114, ascribed to this specins by Marshall, is 

 now retjarded as synonymous with Calltdiota (Mesoleplus) coxator, Grav. — cf. Forst. Vcrh. Wien. 

 z.-b. Ver. 1876. p. 191 ct Thorns. O. E ix. 910.
