 the same, 1st and '2nd joints of abdomen black or blue purple above, apex 

 with a curved line of strong punctures, biemarginate, forming 3 scarcely 

 visible teeth : wings nearly transparent, nervures piceous : antennae and 

 tarsi black, basal joint of former green. 



From beginning of June to August, near London ; in Norfolk ; 

 Kimpton near Andover; New Forest, and Glanville's Wootton. 

 I find this species on old posts and dead trees : and Donovan says 

 it is common on fruit-trees.

It is remarkable that Fabricius in his essential character, says, 

 " the anus is quadridentate;" and in his specific description, which 

 immediately follows, he says " that the anus is unarmed."
