V. pilosa is rare in Denmark, Dyrehaven, Geel Skov (the author), 

 on Funen at Hvidkilde (Miss E. Møller) and a specimen, probably 

 from North Sealand (Schlick), in all two males and two females; 

 the dates are ^Vs — V?. As seen from the description my specimens 

 belong to a dark form with black halteres and strong, bristly hairs 

 round scutellum, answering to var. setosa Verr.
