72 BEES OF GREAT BRITAIN. 



Female. Length 6-6h lines.— Black ; the pubescence on the 

 face dark brown, above the insertion of the antenna and at the 

 sides It IS black ; on the cheeks, margin of the vertex and 

 thorax above the pubescence is fulvous ; on the sides and on 

 the femora it is paler; the scopa bright fulvous, the pubes- 

 cence on the tarsi dark fuscous ; the wings subhyahne, their 

 nervures rufo-testaceous. Abdomen nigro-seneous, ovate, and

Male. Length 5-6 lines,— The face clothed with reddish brown 

 pubescence ; the antennae not quite so long as the thorax, the 

 joints subarcuate ; the legs and thorax have a fulvous pubes- 

 cence, not so bright as in the female; the abdomen nigro- 

 seneous, ovate, and thinly covered with fulvous pubescence ;

This species is very abundant in the London district ; whether 

 It occurs m the north of England is not known, but it has been 

 received from Ireland ; it appears in April, and may be frequently 

 captured on the Dandelion. To the entomologist, this bee will 

 always possess an additional interest, from the fact of its being 

 the species on which Kirby first observed the Stylops Melittce; 

 it IS remarkable that amongst the number of species which I 

 have captured attacked by Stylops, I never found A. nigro-cenea 

 infested by the parasite.
