Phobocampa] BRITISH ICHNEUMONS. 135 



terebra not extending beyond the anus. Legs somewhat stout, with elon- 

 gate calcaria; hind tibiae spinulose and usually whitish, with unguiculi 

 and claws small. Wings with tegulae whitish and stigma somewhat 

 large ; areolet minute and obliciue, with a short and stout petiole ; apical 

 abscissa of radial nervure elongate and forming nearly a right angle with 

 the basal; discoidal cell a little longer than the brachial, its apex strongly 

 acute below ; nervellus and the postfurcal lower basal nervure strongb* 

 oblique. 



Recognised by its short and convex thorax and abdomen of which the 

 9 has the latter centrally dilated, the invariably pale radical callosities, 

 deplanate postpetiole, conspicuous thyridii, small and irregular areolet, 

 strongly acute discoidal cell and concealed terebra, but particularly by 

 the remarkably oblique lower basal nervure. The structure of the last is 

 shared by Spudas/ica, in which the petiole is elongate and the mctanotal 

 areae wanting ; the pupa of P. al/icollis, Thoms., bred from Hvpsipdes 

 elutan'a, is also said to be similar.

Black, with the sec-ond segment apically red; hintl legs with coxae 

 black and rarely discallv red-marked, their tibiae wiiite with tlie base 

 rarely infuscate but apex distinctly nigrescent, their femora red and apic- 

 ally black ; underside of scape and the anterior coxae stramineous ; 

 anterior legs pale fulvidous and postpetiole quadrate. Length, 4.^-bmm. 



Known from all the other species by the dull and linear mesosternal 

 imjjression beneath the speculum, the less distinct mctanotal carinae, 



* Limneria Dtimeticola, Holmgr. (Sv. Ak. Handl. 1858, p. 77, ? : not since mentioned !)>• any author), 

 is most closely allied in our fauna to P. obscurella and known only from Sweden, where Thomson 

 did not meet with it. We have no real claim to it as Mritish for the only rt'ference is by Hairslow 

 (Trans. Yorks. Nat. Union, 1882, p. 106), who prefaces it with a query, from York in 1881, remarking 

 " Mr. BridKuian says of this ' that it approaches nearest the description of dumeticoUi but not 

 exactly' and adds that 'it does not a^ree with any recorded British l.imniTia.'" Ilolmnrcn's ? is 

 so little known everywhere that it would be premature to admit it upon such inconclusive evidence.
