BRITISH ICHNEUMONS. 203 



apically sub-truncate or slightly emarginate ; mandibles slender, bidcntate ; 

 internal orbits and, in ? , sometimes a central facial mark, fulvescent ; $ 

 has clypeus and face white or white-marked. Antennae somewhat slender, 

 setaceous, black ; of ? only white -banded with the sixth flagellar joint 

 quadrate ; scape of c? sometimes white-dotted beneath. Thorax black 

 with pronotum and lines before and beneath the radix llavous ; areola 

 quadrate ; costulae obsolete ; coxal areae distinctly discreted ; apophyses 

 distinct. Scutellum flavous, sometimes basally black. Abdomen some- 

 what broad, black with a very faint blue reflection ; segments one to three 

 with two apical flavous marks ; sixth usually, and seventh flavous-marked ; 

 post-petiole aciculate ; gastrocaeli small and superficial, intervening space 

 often finely aciculate ; apical segments of ? nitidulous. Legs normal, 

 black ; tibiae broadly flavo-white-banded ; anterior tarsi piceo-red, of S 

 stramineous with anterior coxae white-marked. Wings a little clouded, 

 stigma fulvous; areolet narrowed or coalesced above. Length, 13-17 mm. 



The variety novitiiis differs from the type only in having the flavous 

 marks on the basal segments coalesced into an apical band, the third 

 segment occasionally being immaculate. 



This species is much rarer than the preceding, being found only in 

 Germany, Sweden and Belgium, upon bushes, in August. The only 

 British examples I am able to instance are that bred by Bignell, in South 

 Devon, at the end of May, 1882, from Noctua brun/iea, and that captured 

 in the neighbourhood of Guildford, by Dr. Capron, in 1879^; it was, how- 

 ever, known to be a British species in 1872.

$ . Head small, transverse, narrowed behind the prominent eyes, evenly 

 punctate, dull, black ; clypeus truncate, not discreted ; mandibles biden- 

 tate, piceous ; palpi ferrugineous ; facial orbits narrowly flavous. Antennae 

 black, flavous-banded. Thorax normal, black ; metathorax rugose, costae 

 strong ; areola slightly transverse, apically emarginate ; costulae wanting ; 

 petiolar area tri- divided ; spiracles elongate. Scutellum flat, punctate, 

 shining, dull flavous. Abdomen broad, sub-ovate, black, apically obtuse ; 

 post-petiole and base of second segment centrally striolate ; first segment 

 abruptly explanate, with very prominent spiracles ; gastrocaeli small, 

 striate ; incisures narrowly aciculate ; segments five, six and seven with 

 dorsal flavous marks, that on sixth being the largest and longitudinal ; 

 ventral segments two to four plicate, hypopygium not produced. Legs 

 normal, piceous ; femora and coxae darker ; apices of front femora dull 

 flavous. Wings infumato-hyaline ; tegulae black ; nervures and stigma 

 fulvous ; areolet small, narrowed above. Length, 14 mm. 



The above description is taken from the only example remaining in 

 Stephens' collection ; he says the ? , which very probably appertained to a 

 different species and was, perhaps, removed by him before presenting his 

 types to the nation, differed from the c^ in having the scutellum only pale 

 at its apex, and the abdomen broader and duller. 



1 III Dr. Capron's collection (which I have recently acquired) arc tliree specimens,;? i ? , inider 

 this name; these certainly do not bi;long to A. margincgultalm ; his record must, conseiiuently, be 

 regarded with suspicion.
