Entirely black with only the femora and tibiae red, and the hind tibiae 

 apically with ventral plica nigrescent ; lateral petiolar sulci distinct. 

 Length, 6-7 mm. 



Only one other species, and that not British, has the whole abdomen 

 black above. 



Probably much mixed with other knids of these difficult genera. 

 Holmgren took several specimens in Scandinavia in July and August ; 

 France (Gaulle) ; and Belgium in August (Tosquinet). Bignelltook it at 

 Bickleigh early in August ; and I possess several Surrey females in 

 Capron's collection, with one found in Bentley Woods on hazel along 

 with O. fulvivcniris in the middle of July, 1902, and one beaten from 

 birch in Tuddenham Fen early in the following June.
