Campoplex] BRITISH ICHNEUMONS. 91 



face short, somewhat coarsely but not closely punctate ; eyes internally 

 subeniarginate ; mandibles partly pale, somewhat .stout and hardly 

 narrowed apically. Antennae elongate and apically attenuate, with the 

 joints there not discrcted; basal flagellar joint half as long again as the 

 second. Thorax with pronotun) laterally rugose ; mesopleurae somewhat 

 strongly but not very coarsely punctate ; metathoracic impression deep, 

 densely and arcuately trans-striolate ; areae wanting. Abdomen black 

 with the second segment a little longer than third and its apical half red, 

 with the three (except disc of fifth) following and the ventral plica con- 

 colorous ; basal segment with small lateral foveae, postpetiole narrow and 

 and subparallel-sided ; terebra short. Legs fulvous with coxae, trochan- 

 ters, intermediate femora to beyond their centre and the hind ones 

 entirely, black ; hind tibiae piceous at both extremities. Wings with 

 areolet narrow and subsessile, emitting recurrent nervure from its centre ; 

 radial nervure apically slightly sinuate ; radial cell narrow, emitting areolar 

 nervure from its centre; discoidal cell apically rectangular below. Length, 

 8-9 mm. 



This species is distinct in its metathoracic structure, the third and 

 fourth with nearly apical half of second segments red and remainder with 

 cyaneous reflections, the spiracles somewhat elongate, areolet high and 

 emitting recurrent nearly from its centre, the striolae before mesopleural 

 speculum distinct, hind tibiae obviously spinulose, the face short and 

 strongly punctate. 



France, Germany and Stockholm. " Cauipophx siibolicita, Fst.," is 

 recorded from Felthorpe in Norfolk during June by Bridgman (Tr. Norf. 

 Soc. 1894, p. 619), with no note as to its novelty as British.

A black species with the abdomen centrally, and the legs partly, red in 

 9 or flavous in ^ ; ventral plica infuscate ; vertex somewhat incrassate ; 

 petiole attenuate, with no lateral sulci ; and the radius obviously sinuate 

 apically. Length, 7-9 mm. 



This species is known by the head being but slightly constricted 

 behind the eyes, the pronotum not striolate below, the metathorax almost 

 excarinate, with its central impression trans-strigose, the radial cell narrow 

 with its inner nervure distinctly inflexed apically, the lower basal nervure 

 a little postfurcal, the basal segment with neither lateral sulci nor 

 impressed lines and petiole gradually merging into the postpetiole, the 

 second segment apically broadly with the third and fourth entirely or in 

 J except apex of the latter red, ventral plica infuscate, the anterior legs 

 red-varied with the ^ anterior coxae apically pale, the face cjuadrate and 

 somewhat densely griseopilose. Sometimes the hind femora are red 

 beneath and badious above. It differs from the following species in 

 having the second segment but slightly longer than the third ; and from 

 the last in its much more finely punctate mesopleurae and not laminately 

 elevated genal co.sta.
