Head sub-triangular, narrower than thorax ; cheeks nitidulous and not 

 buccate, palpi flavous ; of $ with mouth and face flavidous-white ; of $ 

 with facial and vertical orbits, the not prominent epistoma, a mandibular 

 mark and usually another on the apically truncate clypeus, red. Antennae 

 of S elongate, apically attenuate, black, with scape beneath and a central 

 flagellar band white ; of ? centrally incrassate and white-banded, basally 

 rufescent (at least beneath) with scape infuscate above. Thorax black, 

 dull, very finely punctate and pubescent throughout ; epomiae and notauli 

 short ; a dot beneath, and in S before, the radix testaceous ; mesosternal 

 sulci distinct, not reaching the centre ; nietathorax apically obliquely trun- 

 cate, with the discreted petiolar area and sub-parallel-sided areola distinct ; 

 pleural costa very, coxal and lateral less, determinate ; of S dorsally san- 

 guineous-marked. Scutellum, and sometimes in 9 post-scutellum, flavous- 

 white ; of $ somewhat, of $ strongly, convex. Abdomen of 6 elongate, 

 of ? sub-oval, sub-convex, shining, obsoletely punctate and pubescent ; 

 red, with the apical three or four segments black ; post-petiole of ^ 

 glabrous, gradually dilated apically, nearly twice longer than broad, of $ 

 somewhat elongate, slightly curved, a little dilated apically, immarginate, 

 finely pubescent with no dorsal carinae ; segments four to six of $ with a 

 prominent ventral fold, the sixth to the eighth retractile and the seventh 

 dorsally pale, its terebra straight and rather shorter than the abdomen. 

 Legs somewhat stout, red ; all the coxae, excepting sometimes the front 

 ones of the (^ and marks on the hind ones in $ , black ; anterior tro- 

 chanters sub-infuscate above ; hind femora nearly entirely black ; anterior 

 tibiae obviously, the hind ones hardly, spinulose. Wings fulvescent or 

 sub-hyaline ; areolet strongly convergent above ; radix silaceous, tegulae 

 infuscate and sometimes centrally pale ; nervellus intercepted far below its 

 centre. Length, 8-12 mm. 



This species, which is distributed throughout northern and central 

 Europe, was first recorded from Britain by Desvignes in 1856, and it 

 does not appear to have been since mentioned in any of the local lists or 

 records. Both sexes are, however, represented in Dr. Capron's collection 

 from the neighbourhood of Shere, in Surrey, and Marshall has captured 

 females at Botusfleming, in Cornwall.
