9 . Slightly more shining than the last-described species. Head black, 

 palpi testaceous, labrum red, and Holmgren says the clypeus also ; margin 

 of the face between the antennae sometimes red -marked, frontal orbits 

 always black ; temples and cheeks broad. Antennae short and very stout, 

 third joint quadrate ; central band white, the remainder black ; paler, with 

 the scape red, beneath. Thorax immaculate, distinctly dorsally deplanate ; 

 metathorax somewhat coarsely scabriculous; areola sub-quadrate or broader 

 than long, its costae being less distinct than in fabricator. Apex of the 

 scutellum sometimes red. Abdomen ovate, black or badious, the anterior 

 incisures rufescent ; post-petiole sub-glabrous, carinae not elevated ; second 

 segment punctate ; gastrocaeli nearly wanting ; thyridii distinct ; seventh 

 segment often apically pale ; terebra somewhat incrassate, very shortly 

 exserted. Legs red, coxae and base of trochanters black or fuscous, all 

 the tibiae somewhat thickened and externally broadly white in the centre ; 

 hind tibiae, except centrally, and tarsi fuscous or red ; hind coxae punctate 

 throughout and not scopuliferous. Wings in both sexes sub-hyaline ; 

 areolet sub-deltoid ; stigma fulvous ; radial nervure externally decidedly 

 inflexed at the apex. 



$. Head black; palpi, mandibles, labrum, clypeus and face entirely 

 stramineous ; cheeks so short as to be almost wanting ; exterior orbits 

 usually pale-marked. Antennae with no white band, fuscous ; paler, with 

 the scape pale flavous, beneath. Thorax black, moderately elevated in 

 front, a dot before the radix rufescent ; apex of the scutellum usually 

 flavous, sometimes entirely black ; upper metathoracic areae incomplete ; 

 areola a little broader than long, sub-lunar, apically truncate. Abdomen 

 badious or blackish, anterior incisures and thyridii ferrugineous ; post- 

 petiole sub-quadrate, centrally very nearly smooth ; second segment punc- 

 tate ; gastrocaeli nearly wanting ; thyridii distinct, sub-rotund, much less 

 linear than \x\ fabricator. Legs pale red, the coxae and base of trochanters 

 black, generally with the hind tarsi, and sometimes the apex of the tibiae 

 infuscate. Length, 5-8 mm. 



This species appears to vary much less than the preceding, to the typical 

 forms of which it bears a most confusing similarity, especially in the sculp- 

 ture and brilliancy of the abdomen ; both sexes are, however, always smaller 

 and the extremity of the radial nervure is more incurved. The $ may 

 instantly be known by the absence of the scopulae on the hind coxae, as 

 well as by the thicker flagellum, the post-annellus which is hardly longer 

 than broad, and by the apex of the clypeus and scape of the antennae 

 beneath being dark red. In the $ the post-petiole is sub-quadrate, and 

 nearly smooth centrally, the face entirely pale, and the cheeks hardly 

 visible, the tegulae are not pale and, above all, the thyridii are ovate-rotund 

 and not linear. 



I am of opinion that this species is commoner in Britain even than
