BRITISH ICHNEUMONS. II3 



gastrocaeli large and deep, intervening space distinctly aciculate ; terebra 

 slightly exserted. Legs black ; all the tibiae and tarsi white, with the 

 apex more or less broadly black, the anterior being somewhat rufescent ; 

 ? scopulae very narrow. Wings slightly infuscate, less so in <? ; stigma 

 reddish ; ^ tegulae piceous, sometimes white-marked in front. Length, 

 12-16 mm. 



This species is very similar to those of Coelichneionon, and forms a 

 connecting link between the two genera, but it may be distinguished from 

 them by the entirely pale face of thee?, the apically truncate clypeus, and 

 in having no white mark on the capital vertex. 



Stephens found this species about London and records it from Salop 

 and Scotland. Bignell has bred it in Devon, where it is said to be 

 frequent, by the sides of roads, on flowers of Heradeum sphondylium in 

 June and July, from Nodiia brimnea ; and Marshall from Dicranura 

 vinula ; Essex ; Mr. Bradley has found it about Birmingham ; Col. 

 Bingham at Ravenscar, in Yorks., in August ; Miss Chawner in the New 

 Forest and Col. Yerbury, at Glengariff, in the middle of June ; Mr. F. IL 

 Peachell has bred it from a " forced " pupa of some Taenioawipa found 

 by him at Weymouth; the parasite emerged on the 17th of February, 

 through the end of the chrysalis which was entirely bitten off, leaving 

 within the silken cocoon attached to that of its host, this specimen lived 

 four days in a pill box in my study, and a very handsome insect it is when 

 alive. On the Continent, where it is common, it preys upon Smerinthiis 

 populi and Ma?nestra okracea.

A distinct, vespoid species, with no red markings. 9 . Body stout ; 

 head black ; internal orbits flavous ; cheeks beneath and temples dilated. 

 Antennae stout, much attenuate, piceous ; scape flavous beneath and basal 

 half of flagellum bright fulvous, the central joints being paler. Thorax 

 black ; pronotum, callosity beneath radix, and rarely two apical dots on 

 metathorax, flavous ; latter scabrous, posteriorly nearly perpendicular, with 

 five upper areae, of which the areola is sub-quadrate and posteriorly 

 distinctly arcuate. Scutellum flavous, sub-quadrate, not transverse, ob- 

 soletely punctate. Abdomen broad, sub-obtuse, black, with all the 

 segments broadly flavous-margined, five to seven with the colour some- 

 times abbreviated laterally ; post-petiole aciculate throughout ; second 

 segment with gastrocaeli large and somewhat deep and the intervening 

 space aciculate, as broad as centre of post-petiole ; terebra scarcely 

 exserted, central ventral segments flavescent. Legs black, hind tibiae 

 sinuate at base ; anterior femora apically, tibiae and tarsi, flavous ; hind 

 legs with tibiae, excepting apex, tarsi and often a coxal mark, flavous ; 

 hind coxae without scopulae, setigerous apically beneath. Wings flavescent; 

 stigma pale croceous ; radix and tegulae flavous. 



$. Head black; mouth, clypeus, face and frontal orbits flavous or 

 mandibles basally and a longitudinal facial line black. Antennae black,
