Head but slightly constricted posteriorly with the vertex somewhat 

 broad ; palpi stramineous, mandibles centrally flavidous or ferrugineous. 

 Antennae hardly longer than half body in both sexes, with ($ scape dull 

 fulvous and 9 scape dark testaceous beneath, flagellar apices subattenuate. 

 Thorax distinctly convex and dull with traces of elongate and subparallel 

 notauli, sternauli half length of mesosternum and apically deeply im- 

 pressed ; mctathorax basally nitidulous and very finely punctate ; areola 

 not longer than broad, its carinae strong and apically obsolete ; costulae 

 strong and entire. Abdomen dull, pubescent and apically compressed ; 

 immaculate black, with the sixth segment entire ; postpetiole centrally 

 subtumidulous, longer than broad, nearly as long as and double breadth 

 of the petiole ; second segment of (^ double and ot 9 one and a half 

 times as long as apically broad ; the third of ^ elongate and of V sub- 

 quadrate ; terebra half length of body, slightly reflexed. Legs slender 

 and fulvous, with anterior coxae and trochanters of ^ and sometimes of 

 $ flavous or fulvidous, occasionally black ; hind coxae and their tro- 

 chanteral base black, kitter apically flavidous; hind femora and tibiae 

 fulvous, with extreme apices of the former and both the apex broadly 

 and a band before base of the latter more or less nitensely black, some- 

 times merely infuscate or obsolete ; centre of hind tibiae varies from 

 rufescent testaceous to stramineous white ; hind tarsi infuscate with 

 calcaria and basal half of their first joint white. Wings normal and sub- 

 hyaline with stigma piceous or luteous, never stramineous ; radix and 

 tegulae stramineous ; areolet subregularly triangular, petiolate or sub- 

 petiolate, always distinctly oblique and emitting the recurrent nervure 

 nearly from its extreme apex. Length, 7-7I mm. ^ 9 • 



Authors appear to have been unable to interpret Gravenhorst's descrip- 

 tion because he gives his female so small a size that it has — at least in 

 England — been constantly applied to A. annillata (by Bridgman) and A. 

 fcncstralis (by Capron), than both of which it is distinctly larger, usually 

 with fully the seven millimetres accorded to his male by Gravenhorst, 

 whose account of the areolet and postpetiole are very distinctive, apply- 

 ing equally to both sexes of the species as I understand it. The hind 

 tibiae vary considerably in depth of colouration and I consider it quite 

 probable that Thomson had the present insect before him, in spite of his 

 "tibiae posticae hand nigro-binotatae" and " coxis omnibus nigris." It 

 is easily recognised by its large size, straight and elongate external radius, 

 the centrally elevated postpetiole and subcontinuous second recurrent 

 nervure. 



It is difficult to say what the older authors understood under the present 

 name, and all their records must be accepted with reserve, though I 

 fancy most or all those of allied species from Nrpommicula-h.o^i'^ should 

 be placed here. Germany, Parma, Genoa, Piedmont and Netley in 

 Shropshire from May to September, rarely on flowers (Gravenhorst); bred 

 from Pluiella porrecicUa, a lortrix and from a Ncmattis larva, according to 

 Brischke, who describes the cocoon as "eliptisch, diinnwandig, etwas
