Gonotypa] BRITISH ICHNEUMONS. 159 



This genus is obviously allied to Angitia inscctalor, Schr., in the cmar- 

 gination of its anal scgnit-nts and nitidulous abdomen, though at once 

 known by its lack of areolet, geniculate nervellus and the very stout 

 spicula, which is strongly impressed discally a little before its apex, with 

 broad and apical ly obtuse valvulae.

Goiiofypti iiiclanostonm. Thorns. O.E. xi. 1137, i ?. Coiiutypiis iticlano- 

 sfoiHiis, Schm. Opusc. Ichn, 1638, S ? . 



A delicate, linear black and shining species, with the stigma broad and 

 infuscate though not black, the tegulae and radices pure white and in J 

 darker ; both mesonotum and metathorax de{)lanate, with the areola con- 

 tinuous with petiolar area from apex to near base; legs dull luteous with 

 tarsal apices, coxae, trochanters but not trochanterelli, and usually though 

 not always the posterior with base of front femora, black ; hind tibiae 

 usually unicolorous, though more often subinfuscate at apex and before 

 base ; upper half of recurrent nervure fenestrate. Length, 4-5 mm. 



1 only know the female of this species; it is very remarkable for having 

 the third to seventh segments strongly emarginate discally, and the 

 terebra both incrassate and discally incised shortly before its apex. 



The species was described from Lund and Yddinge in Sweden ; Schmie- 

 deknecht, who simply copies Thomson's description, gives it a length of 

 5 to 6 mm., adding that he has taken several specimens in Blankenburg, 

 always in dry clearings in woods. It has not before been noticed in 

 Britain and cannot be of frequent occurrence with us, since I have seen 

 only the five females in my own collection. One of these was taken by 

 Capron, probably about Shere in Surrey twenty years ago ; a second was 

 captured by W. H. Tuck on 8th September, 1900, at Tostock in Suffolk ; 

 I swept two from reeds in a brackish ditch at South wold on the coast, 

 I ith September, 1907, and took another in Blythburgh Wood in the same 

 neighbourhood on 14th September, 19 12. 



NEPIERA, Thomson. 

 Thorns. O.E. xi. 1887, 1137. 



Head somewhat constricted behind the eyes with vertex not broad; 

 clypeus apical ly truncate, with small lateral foveae. Antennae slender 

 and filiform. Thorax elongate, with large white anteradical callosities ; 

 metathorax narrow and not convex with Hne areae and obsolete costulae; 

 areola strongly elongate, subpi'Utagonal and apically incomplete. Abdo- 

 men cylindrical and parallel-sided in both sexes, multifasciate ; petiole 

 not short, with lateral sulci and scrobes distinct ; spiracles of the strongly 

 elongate second segment beyond its centre ; terebra very shortly exserted, 

 shorter than petiole. Wings with areolet small and hardly petiolatc-, 

 emitting recurrent from or beyond its centre ; recurrent ntTvure broadly 

 and cubital narrowly fenestrate ; nervellus oblique and hardly geniculate. 



Superficially easily recognised by having every .segment but the first 

 apically narrowly pale, by the narrow form, large pale callosities and 

 hardly exserted terebra. The markings .somewhat resemble those of the 

 Piniplid Phidias aciculalits, though the abdomen is here parallel-sided and 

 narrow.
