238 BRITISH ICHNEUMONS. 



retracted ; petiole with no dorsal carinae ; gastrocaeli very distinct ; terebra 

 scarcely visible. Legs normal, hind ones somewhat long and stout; tarsi 

 slender. ^Vings with areolet narrowed above, i)enlagonal. 



Wesmael at first placed this genus in his Fueiis/ici, on account of iis 

 circular spiracles, but in 1853 he was of opinion that its more natural 

 position was next after riatylabus, in the Fhifyuri, considering the de- 

 planate, sub-truncate and apically retracted abdomen of the $ , in spite of 

 the more slender and more suddenly explanate post-petiole. This opinion 

 he maintained in 1855, and in it he has been followed l)y Thomson (who 

 makes no mention of the genus in his " Opuscula "), Brischke and Holm- 

 gren. Authors of the present day, however, have reinstated it in its original 

 position, which, if not the most natural, is at least the most convenient 

 under our arbitrary and, I hope, ephemeral classification. 



No species of this genus appears to have yet been bred in captivity. 

 A. tnesosikius, Grav., which is generally distributed in Europe, and A. flavi- 

 jueo/iis, Wesm., which is found in Belgium, France, Sweden, etc., out of 

 the eight continental species, are very likely to inhabit Britain.

Head short, black ; frons roughly punctate, centrally sub-canaliculate ; 

 face protuberant ; cheeks externally sinuate and slightly refiexed ; clypeus 

 somewhat convex, sparsely punctate and apically truncate ; frontal orbits 

 pale ; ? with facial orbits red ; $ with mouth, clypeus, face and apices 

 of cheeks, flavous. Antennae attenuate towards apex, slightly thickened 

 beyond the middle ; seventh flagellar joint quadrate ; of $ with flagellum 

 ferrugineous, and scape flavous, beneath ; of $ centrally white-banded, 

 with scape red beneath. Thorax black ; metanotum rugose, with com- 

 plete and determinate areae, of which the petiolar is discreted and trans- 

 versely striate ; apophyses large, stout and acuminate ; pronotum, humeral 

 callosities, and sometimes a mark near the spines, pale. Scutellum white 

 or, in $ ., flavous. Abdomen red; post-petiole strongly and closely punc- 

 tate ; second segment transversely impressed at base, with large and deep 

 gastrocaeli ; the apical segments usually infuscate, with a narrow, pale 

 margin ; petiole of $ black. Legs red ; $ with trochanters, hind femora 

 apically, base and apex of hind tibiae and the hind tarsi, black ; $ with

In his " Miscellanea," mention is made by Wesmael of a $ variety, with 

 the clypeus, second and third segments infuscate, and the last four entirely 

 black; Kriechbaumer (Ann. Soc. Esp. Hist. Nat. 1854) describes ^. /^a- 

 lenricus, $ , which Berthoumieu considers a variety of the present species,
