A NEW SPECIES OF PIMPLINiE. 



By Claude Morley, F.Z.S., F.E.S. 



In May, 1908, Mr. G. T. Lyle noticed that many aborted 

 flower-heads of gorse near Brockenhurst, in the New Forest, 

 contained larvse, and from these he bred the Cecidomyiid, 

 Aspondylia ulicis, Trail, together with several Chalcid parasites. 

 During the following September the seeds of the gorse were 

 much galled, and he collected a good many affected pods, 

 breeding from them the same Cecidomyiid and two species of 

 Chalcididffi. On September 20th two Ichneumonids emerged 

 from the galled seed-pods, and some three or four hours after 

 emergence were seen to be in cop. During 1909 Mr. Lyle failed 

 in attempts to breed more of this Ichneumonid, but in the 

 autumn of 1910 he was rewarded by the presence of five males 

 and one female of the same species from the pods. He has 

 been so good as to allow me to examine these, and, since they 

 have certainly not been previously brought forward, I propose 

 to call them 



Pimpla ulicicida, sp. nov. 



Head black, with only the palpi pale ; mandibles slender, with 

 teeth of equal length. Antennae slender, filiform, and hardly longer 

 than half body. Thorax nitidulous, and finely punctate throughout, 

 with notauli short but deeply impressed ; mesonotum entirely or 

 broadly at sides and base, mesopleurae and sternum more or less 

 broadly, and metapleurae always, with metanotum often, bright red ; 

 tegulae and a circular callosity beneath them stramineous ; meta- 

 notum longitudinally bicarinate, with no discal areas, and the petiolar 

 very short ; spiracles quite circular and not very small. Scutellum 

 and postscutellum always entirely red. Abdomen linear, strongly 

 punctate and white-pilose, with the tubercles obsolete as in Sca-mbiis ; 

 entirely black above, with the segments longer than broad, and be- 

 coming quadrate at fourth in female and sixth in male ; basal segment 

 parallel- sided, of male twice and of female but very slightly longer 

 than broad, punctate throughout, male with discally parallel caringe 

 extending nearly to its apex ; terebra exactly as long as abdomen. 

 Anterior legs stramineous, with only the onychii infuscate ; front
