Female. Length 3-3£ lines.— Black, with an aeneous tinge; the 

 head quadrate ; a line in front of the anterior ocellus extending 

 to the sulcation of the face, another behind it which runs to 

 the posterior margin of the face ; the scape and mandibles yel- 

 low, the latter ferruginous at their apex ; the inner orbits of 

 the eyes and the clypeus covered with silvery pubescence. 

 Thorax finely punctured aud pubescent ; the metathorax with 

 an enclosed subcordiforni space at its base longitudinally stri- 

 ated, beyond which the striation is transverse ; the wings 

 slightly coloured, the nervures and tegulae piceous, the extreme 

 base of the wings yellowish ; the anterior tibiae in front, and the 

 intermediate and posterior pairs at their base, yellow ; the tarsi 

 piceous, their basal joint darkest ; the anterior tarsi ciliated in 

 front, and the intermediate and posterior tibia? spinose. Ab- 

 domen covered with fine downy pubescence, the apical segment 

 punctured, its apex rufescent. 



Male. Length 3 lines. — Closely resembles the female ; but has 

 the apex of the scape, an interrupted line on the collar, the 

 tubercles, tips of the femora, the tibiae and tarsi, yellow ;; the 

 tibiae with a black stripe behind and the apical joints of the 

 posterior tarsi piceous ; the apex of the intermediate tibite 

 within and also the basal joint of the tarsi with a fringe of 

 long curled white hair. 



This is not a scarce species, and is widely distributed. It is 

 plentiful about London ; and I have taken both sexes in York- 

 shire during July.
