182 BRITISH ICHNEUMONS. lAfioilia 



Thorax longer than broad, witli a flavous callosity before tin- concolorous 

 tegulae ; metathorax subelongate with the apically subentirc areola hex- 

 agonal and longer than broad, and the costulae not always discreted. 

 Abdomen black with the second segment apically, third and fourth 

 except base of former, and apices of the remaining segments rufescent ; 

 postpetiole longer than broad, double breadth of and not longer than 

 petiole ; second segment about a third longer than broad, in ^ somewhat 

 longer with its basal third constricted at the large and pale thyridii; third 

 subquadrate ; terebra about a third the length of basal segment. Legs 

 slender and pale red; anterior coxae and all the trochanters flavous; hind 

 coxae except apically black ; hind tibiae and tarsi not at all infuscate, uni- 

 colorous fulvous. Areolet sessile or subsessile, emitting recurrent nervure 

 at or slightly beyond its centre ; nervellus quite straight and not genicu- 

 late. Length, 4.5-5 mm. 



Schmiedeknecht has correctly pointed out that there is no such insect 

 as Limncria gracilis, Holmgr., and the present species is equally certainly 

 neither Campoplcx gracilis, Grav.," nor Ratz. He considered its position 

 under Angitia very doubtful, and thought it as least as closely allied to 

 Olesicampa — mainly because Bridgman considered it " comes very near 

 Limneria lougipcs, but the antennae is differently coloured, as are the 

 coxae and trochanters; the insect is also much smaller, and the head is 

 not so large " — though he seems to have overlooked Bridgman's express 

 statement " teeth of mandibles of equal length," which at once excludes 

 it ; if it could be there placed it would fall into Thomson's group P] at 

 p. 1 143. Thomson considered the present species to be very similar to 

 A. aliernans in the characters indicated under the latter, but to differ in 

 having the metanotal costulae wanting, the hind tibiae dull stramineous 

 with apices infuscate, their femora sometimes concolorous, and the abdo- 

 men centrally less broadly red. 



Both sexes Avere originally bred at Worcester by Fletcher on 13th 

 August, 1873, from the cocoons of Elachista cerussella, in leaves of grass 

 and a doubtful male variety, with darker antennae and apices of the 

 second to fourth segments alone rufescent, was captured at Brundall near 

 Norwich ; the latter was probably later found to be distinct, for Bridg- 

 man does not include this species in his Norfolk List of 1894. I possess 

 a single male (headless, but agreeing in every way with the type, which I 

 have examined at Norwich, certainly belonging to Angitia), given me by 

 Hartley Durrant and bred by Barrett from " I'Jlacliisia ccn/ssclla," which 

 exactly agrees with Bridgman's tvpe, especially in hind tibial colour. I 

 do n(jt find that Thomson took it in Sweden.

* I have traced Thomson's error in Bridgman's Norwich collection, where the larger examples 

 stand under the name " rtificoniis, Bridg." (in MS.) and the smaller incorrectly under that of 

 Limneria "gracilis" (cut from Marshall's 1872 catalogue); the latter is Gravenhorst's name, but 

 Bridgman in writing to Thomson — from whom are many, apparently cotypical, specimens of Swedish 

 species at Norwich — probably inserted ■' Hohngren," without referring to that author.
