76 BRITISH ICHNEUMONS. [Pitup/a. 



15. punctiventris, Thorns. 

 Piinpla punctiventris, Thorns. O.E. viii. 756 et xiii. 1414, cj ? . 



Black. Head with the vertex somewhat broad and hardl\- narrowed 

 behind the eyes ; whole head, including all the orbits and j face, im- 

 maculate ; clypeus obviously depressed and emarginate apically. Scape 

 black in both sexes. ]Metathoracic areae entirely wanting ; spiracles cir- 

 cular. Abdomen of both sexes parallel-sided and of J linear ; sparsely 

 and strongly punctate, sometimes infuscate-testaceous, with the apices of 

 the segments always distinctly though narrowly nitidulous; basal segment 

 transverse in both sexes, and strongly and closely punctate on either side ; 

 (5' with the second segment subquadrate ; terebra not shorter than the 

 abdomen, spicula obliquelv truncate at its apex. Legs red with the coxae, 

 excepting sometimes the hind ones of the 9 - ai^d the base of the tro- 

 chanters, black ; legs of ^ more slender with the hind femora rarely 

 infuscate and the front ones simple, not emarginate ; 9 ^^'ith the claws 

 basally lobate. Radial nervure slightlv sinuate towards its apex ; ner\ellus 

 nearly antefurcal and not intercepted abo^•e the centre. 



The 9 of this species closely resembles P. calohala, but il is a little 

 more slender with the abdomen more })arallel-sided, the tubercles and 

 segmental apices though sufficiently obvious are less elevated, and the 

 basal segment is shorter with its sides very distinctly punctate. Both 

 sexes have the basal segment not longer than broad and laterally punctate, 

 the metathorax with hardly traceable carinae and the coxae black. The 

 (5 materially diflers in its simple front femora. 



This species, which Thomson described from Sweden and Continental 

 authors have so confused with P. calobata as to render its range indis- 

 tinguishable, is said by Bridgman (Trans. Norf. Soc. 1893, p. 630) to 

 occur at Mousehold, near Norwich, though he makes no comment upon 

 the fact that it is new to our fauna. If his records of its breeding by 

 W. Fletcher from Cokophora inflala, C. pititiella, Laverna epilobiella, 

 Euchromia flammcana, Eupaccilia atricapilana and P^.flaiHci liana be correct, 

 it cannot be of rare occurrence with us, but as 1 have stated, he did not 

 know P. calobata, Grav. It appears to be abroad exclusively in the late 

 summer : I have two females taken by the late Mr. Alfred Beaumont, at 

 Plumstead, on 7th August, 1897, and five males taken by myself at 

 Westleton, Beccles, Tuddenham Fen and Kessingland, in Suffolk, between 

 30th July and 29th September by sweeping, and on the fiower-heads ot 

 Daiicus carota and Angelica.

A small red species with only the head, part of thorax and apices of 

 segments black. 9 • Head black and constricted behind the eyes ; face 

 short shining and distinctly punctate ; palpi fiavidous, orbits immaculate. 

 Antennae infuscate and not longer than half the body, rufescent beneath 

 with the scape paler. Thorax red with the prothorax, mesosternum, apex 

 of the diffusely punctate pleurae and, except apical lateral marks, the meta- 

 thorax black ; metathorax short, convex, shallowly and diffusely punctate 

 with the subobsolete areola slightly depressed and slightly shining, with 

 the lateral costae wanting; spiracles circular. Scutellum and postsculel-
