This insect is very variable in colouring, apparently being in- 

 fluenced in that respect by the atmosphere. In hot dry summers I 

 have found nearly every female highly coloured ; whilst in a cold 

 wet season all have been the black form described by Kirby as a 

 distinct species. The male is found, with the base of the abdomen 

 more or less red, on the Continent ; such have been received from 

 Albania and the south of France ; but a coloured male has not, to 

 my knowledge, been taken in England. The species has been 

 received from France, Italy, Germany, Albania, Denmark, and 

 Sweden, but is very local in this country; it has been found at 

 Erith, Darenth and Birch Woods, Kent, but most plentifully at 

 Kingsdown, near Warmer Castle ; in Devon, at Teignmouth and 

 Dawlish ; it has also occurred in South Wales. It is found during 

 July and August, and is partial to the flowers of the wild scabious 

 (Scabiosa arvensis).
