BRITISH ICHNEUMONS. 225 



The hind tibiae appear to be almost constantly black throughout. 



It varies sometimes in having pale lines before and beneath the radix, 

 and may be known from P. pulliis^ Wesm., by the equally broad head and 

 thorax. 



I have no doubt that Eridgman's $, was that of Holmgren's species, 

 though Berthoumieu has separated them on the basis that in the latter 

 the frons is finely punctate and in the former entirely glabrous, though 

 described as " almost free from punctures " by Bridgman ; the sub-glabrous 

 base of the second segment appears identical in both and at once dis- 

 tinguishes this species from the preceding, of which I am by no means 

 sure that it is more than a variety. 



Bridgman introduced the female as British, in 1884, on the strength of 

 an example, taken by Rev. E. N. Bloomfield, near Guestling, in Sussex. 

 Five years later he described P. tra?isversus, with no reference to its simi- 

 larity with P. pumilio, from two males, bred by Cross, of Ely, from the 

 larvae of Cidaria sagitiata, in July. Piffard has taken P. transversus, at 

 Felden, in Herts. ; Rev. C. D. Ash has bred it at the end of June, from 

 Dianthaecia carpophaga, from Shoreham, in Sussex ; and Thornhill has 

 given me both sexes, bred together from osier twigs, doubtless containing 

 larvae, at Cambridge, in the middle of July. P. pniniiio occurs in Sweden, 

 Lapland and Germany.

Head black, narrowed behind the eyes ; cheeks sinuate ; clypeus apically 

 sub-truncate or slightly rounded \ frons somewhat glabrous, sparsely punc- 

 tate, centrally sub-canaliculate ; face and cheeks sometimes rufescent ; all 

 the orbits white ; c^ also has palpi, mandibles, angles of clypeus, and the 

 facial orbits broadly, or the whole face, white. Antennae slender, apically 

 attenuate ; scape white beneath ; ? with the flagellar joints a little ex- 

 planate beyond the centre, and the central ones in both sexes with a white 

 band, often obsolete or wanting in $ , which latter has the fifth and sixth 

 flagellar joints carinate. Thorax shining, black, with lines before and be- 

 neath the radix, dots on the mesopleurae, in the pleural areae and two in 

 the petiolar area, white ; $ usually with two white vittae on the meso- 

 notum ; areola short ; costulae and coxal areae entire ; apophyses distinct, 

 though very small ; spiracles elongate. Scutellum and post-scutellum 

 white, former carinate to beyond its centre. Abdomen nitidulous, black, 

 with all the segments broadly white-margined ; first segment feebly 

 arcuate ; post-petiole smooth or shagreened, carinae sub-obsolete, apical 

 angles obtuse ; gastrocaeli sub-obsolete, thyridii distinct, intervening space 

 scabriculous ; following segments smoother ; ventral fold white or flavidous, 

 extending to fourth segment ; terebra slightly exserted. Legs normal, pale 

 red ; coxae and apices of hind femora, tibiae and their tarsi, black ; an- 

 terior coxae of $ sometimes rufescent, of c^ white ; tarsi of $ sub-spinulose 

 beneath. Wings sub-hyaline ; stigma fuscous, radix white, tegulae nigres- 

 cent ; areolet coalesced above. Length, 8-9 mm. 



At once distinguished from P. variegaius by its smaller apophyses and
