280 BRITISH ICHNEUMONS. [Aphanoroptnwi. 



with the scape, and in 9 two or three basal flagellar joints, black. Thorax 

 gibbulous and immaculate; metathorax evenly and not very closely punc- 

 tate, with the basal area wanting ; areola pentagonal, apically truncate 

 and emitting the costulae from a little before its centre ; petiolar area 

 vertical and not discreted. Scutellum immaculate. Abdomen ovate- 

 cylindrical, slightly longer than the head and thorax and as broad as the 

 latter, finely punctate ; basal segment gradually explanate throughout, 

 nearly twice longer than broad, canaliculate and black with the apex, like 

 the remainder of the abdomen, red ; second segment sometimes trans- 

 versely impressed before its apex ; $ with all the segments more or less 

 indeterminately infuscate, at least centrally ; terebra half length of abdo- 

 men, black with the spicula red. Legs testaceous red with the coxae and 

 trochanters, except the apices of the latter, black ; posterior femora 

 broadly black in the centre ; hind tarsi of ^ subinfuscate. Wings some- 

 what short, slightly clouded ; stigma and radius testaceous, radix and 

 tegulae red with the latter broadly black basally ; areolet sessile. Length, 

 6 — 7 mm. 



This species appears to be rare or local on the Continent and few 

 authors make mention of it. There can, I think, be but little doubt res- 

 pecting the correctness of the synonymy here adopted, since the two 

 descriptions of Gravenhorst agree almost word for word throughout, 

 though it is strange that he should twice refer to so distinct an insect. 

 Thomson places the former in this genus, which he beautifully delineates, 

 but he does not synonymise it with Pimpla ahdominalis. Schmiedeknecht 

 allows Lissonoia 7'uficoniis to remain in its original genus as an insufficiently 

 defined species. It is abundantly distinct from the genus Pimpla, in which 

 it so long stood, by the protuberant hypopygium and strongly costate 

 metanotum. 



As far as I am aware it is only recorded from Volhynia and Warmbrunn, 

 on umbelliferous flowers in August by Gravenhorst ; from Sweden by 

 Thomson ; and from Insterburg in Prussia by Brischke. As Bridgman 

 remarks {I.e.) it was taken with us by Dr. Capron in the neighbourhood of 

 Shere in Surrey in i88o, and from these the former first described the 

 male ; these specimens of both sexes are now in my collection and no 

 one appears to have since met with it in Britain, though there is a single 

 ancient female from Stephens' collection in the British Museum. It has 

 hitherto been nowhere bred.
