Campopkx] BRITISH ICHNEUMONS. 85 



central inetathoracic impression acutely transriigose. Abdomen blac:k 

 with tlu» third segment entirely, ajjcx of the second and sides of the 

 fourth fulvous; third segment with no elevated lateral margin nor black 

 lines, or with the latter obsolete. Legs fulvous with only tlie coxae and 

 trochanters black, the anterior of the j being partly flavous; liind femora 

 fulvous in both sexes, rarely subinfuscate at base and apex. Wings with 

 the areolet petiolate, tegulae fulvous and mrNellus hardly geniculate. 

 Length, 7-9 mm. 



Our only species with the head transverse, frons carinate, basal abscissa 

 of hind wing radius short, postpetiole black and scrobes simple; the pale 

 hind femora are i)eculiar. It was thought by Thomson (O.K. xi. 1082) to 

 possibly be a form of C.dissiptiis, Forst. I.e. p. 833 = 6". monozonus, Korst. 

 I.e., p. 781, which in turn Holmgren considered in 1872, p. 52, synonymous 

 with his own C. florkola of 1858, p. 38, though not with (Jravenhorst's 

 type of that name. 



Not known in northern Europe and probably incorrectly recorded from 

 Britain; it is however found in France according to Gaulle, and Tosquinet 

 considers it to occur rarely in Belgium during July. Our only specimen 

 was named by Bridgman and bred in south Devon on i6th June from 

 Eitpitlucia nanata by Bignell (Trans. Devon. Assoc. Sc. i8g8, p. 490).

Head laterally oblique behind eyes; mandibles flavous and pal])i 

 fulvous; frons dull and granulate, conspicuously carinate centrallv, with 

 five carinae radiating from antennal base ; face dull, rugose, pubescent 

 and indistinctly punctate. Thorax with mesonotum finely and sparsely 

 punctate, with interstices subglabrous; mesopleurae normally punctate, 

 with interstices reticulate; metanotum subnitidulous with disc obsoletely 

 punctate, the central impression not very deep and its apical part feebly 

 transrugose; areola well defined, dentiparal areae externally obsolete. 

 Abdomen finely punctate and pubescent, black with the third segment, 

 the fourth except apically, and the second except a lateral line and disc 

 at apex, clear red ; basal segment slender with postpetiole apicall)' sub- 

 explanate and spiracles not prominent ; third segment as long as second, 

 laterally black-lined but not concave beneath; ventral segments concolor- 

 ous. Legs flavous with base of anterior coxae castaneous, their femora 

 subrufescent ; hind coxae, trochanters, and femora black, with their tarsi 

 and both extremities of their tibiae piceous. Wings with radix and 

 tegulae fulvous, stigma castaneous; areolet shortly jx'tiolate and emitting 

 recurrent nervure before centre ; nervellus nearl)- straight, subintcrceptetl 

 far below its centre. Length, 1 1 nnn. ^ o\\\\. 



The peculiar frontal strucLiire a])pcars to riMidcr this sprcics distinct. 



"One specimen taken b) I\lr. Ilarwood " (llridg. /.<.), perhaps about 

 Colchester; the type is probably in i^ridgman's collt-ction in the Norwich 

 Castle Museum. This species is still unknown 011 the Continent, and 

 entirely so to me.
