Female. Length 2^-6^- lines. Black ; the apical half of the 

 maudibles ferruginous. Thorax : the posterior margin of the 

 prothorax angulated ; the metathorax with a slight longitudinal 

 impression at the base, at the apex finely transversely rugose ; 

 the wings slightly coloured and iridescent, a dark cloud cover- 

 ing the apex of the wing from the base of the marginal cell, 

 with a large hyaline spot beyond the third submarginal cell, 

 sometimes obsolete ; the anterior tarsi simple, the intermediate 

 and posterior tibiae serrated on the exterior. Abdomen : the 

 two basal segments and the base of the third red ; the apical 

 segment slightly ferruginous. 



Male. Length 2 j-3^ lines. Very closely resembling the female, 

 with the white spot on the wings usually obsolete ; all the tibiae 

 simple, and the sixth ventral segment slightly ernarginate. 



This species is one of the most abundant ; it is found in all 

 parts of this country, and scattered throughout Europe. The 

 male seldom has the white spot on the wings, and in the female 

 it is sometimes obsolete.
