106 BRITISH ICHNEUMONS. ICjmodusa 



Not common in north and central Europe, nor in Swedish woods in 

 July; Prussia, France, etc. Dr. Capron used to take the female and 

 variety male commonly at Shere in Surrey and sut^jgested their svnonomy, 

 but found no typical males; 1 have beaten the female from birch in 

 Bentley VVoods in the middle of July, swept it in Tuddenham Fen in 

 August and found it on fennel flowers at Alderton early in September, 

 and taken the typical male — which Marshall also gave me from Bishops 

 Teignton — on Aiigclica syhcsln's flowers at Foxhall on 17th September. 

 The \?ir. JJavipis was described from Prussia and is much commoner than 

 either typical sex with us; Bridgman considered it "to be generally dis- 

 tributed in F'ngland. I have taken it at Wimbledon ; Dr. Capron takes 

 it in the neighbourhood of (niildford ; and I have also received it from 

 Mr. Fitch. They have all been males, and I have seen no female which 

 was at all likely to belong to it" (Trans. Ent. Soc. 1882, p. 149); several 

 at Banchory in September, 19 10 (Elliott), Greenings in June and July 

 (W. Saunders), Chobham in the middle of July (Beaumont) and Brock- 

 enhurst (Morice); I have found it on 14th July, 1908, in my Monk Soham 

 garden and swept it in a rough field on 24th julv, 1902, at Gosfield in 

 Essex.

Head transverse, short and very narrow behind the eyes, triangular in 

 front ; clypeus not discreted, apically broadly rounded, subemarginate 

 and mutic; peristomium and mandibles small, the latter moderately broad, 

 constricted apically, with their lower margin generally dilated and some- 

 what reflexed, and teeth of equal length ; cheeks short, with their costa 

 usually continuous ; eyes oblong and nude, at their juxta-antennal orbits 

 deeply and very distinctly emarginate. Antennae shorter than body, fili- 

 form and usually stout. Thorax gibbulous and anteriorly subvertical ; 

 metathorax declived throughout, produced beyond hind coxae, sometimes 

 longitudinally impressed centrally, with the notal areae very incomplete 

 or wanting. Abdomen strongly convex, claviform and broader before 

 anus, apically subdepressed or but slightly compressed; basal segment 

 with spiracles at its apical third, lateral sulci wanting and postpetiole not 

 abruptly explanate ; second with the large thyridii far from its base, and 

 spiracles nearly at its apical third; terebra a little reflexed, not or but 

 very slightly exserted beyond anus. Legs normal and usually a little 

 slender, with unguiculi and the tarsal claws small, the latter pectinate 

 towards their base. Stigma narrow, often emitting radius from its basal 

 third; areolet always distinct, small, petiolate and nearly regular; basal 

 nervure strongly oblique, sometimes continuous; discoidal cell apically 

 acute below ; nervellus simple or geniculate. 



This genus is distinct in its clavate abdomen, small head with short 

 and very transverse vertex, internally strongly emarginate eyes, and the 

 structure of both abdomen and thorax, says its author; which Bridg.- 

 Fitch reduce to "having the margin of the eyes against the antennae 

 notched." The legs show no uniformity of colouration, the antennae 

 are never elongate nor slender, the thorax is always very stout and 

 convex, the lower basal nervure is postfurcal or subcontinuous, the meso- 

 notum dull with the scutellum large and coarsely sculptured, the black or 

 at most centrally red abdomen is disproportionately elongate and nearly
