the apex. Thorax shining and finely punctured ; the meta- 

 thorax opake ; the pubescence on the middle of the disk fuscous, 

 at the sides it is pale fulvous, as well as on the metathorax 

 laterally; the wings hyaUne, faintly clouded at their apical 

 margins, the nervures fusco-ferruginous : the legs have a pale 

 pubescence, the floccus nearly white, having an ochraceous 

 tinge, the scopa of a glittering pale fulvous. Abdomen shining, 

 subovate and convex, very delicately and closely punctured ; 

 the apical margin of the basal segment has on each side a short 

 fringe of pale ochraceous pubescence, the following have a 

 marginal fringe of the same colour, the first usually interrupted ; 

 the apical fimbria rufo-fuscous. 



This insect so closely resembles the following in every parti- 

 cular, except the colour of the posterior legs, that great hesita- 

 tion arises in separating them. A. Afzeliella abounds on Hamp- 

 stead Heath, where it burrows in the sandy spots ; the present 

 species is occasionally found in its company.
