BEES OF GREAT BRITAIN. 83 



Female. Length 5-6 lines. Black ; the face covered with gri- 

 seous pubescence, that on the vertex fulvous, a line of silvery 

 pile on each side of the face in the depressions close to the mar- 

 gins of the eyes; the clypeus strongly punctured, having a 

 smooth line down the centre, the anterior margin deeply 

 emarginate, and produced on each side into a sharp angle. 

 Thorax thinly clothed with pale fulvous pubescence, most dense 

 on the scutellum ; at the sides of the metathorax it is paler ; 

 wings subhyaline, their apical margins clouded ; legs dark fus- 

 cous, the floccus white ; the scopa obscure fulvous above, be- 

 neath silvery ; the legs have a scattered pale fulvous pubes- 

 cence, that on the tarsi beneath ferruginous, their apical joints 

 rufo-testaceous. Abdomen : at the base, thinly clothed with 

 cinereous pubescence, on the intermediate portion it is fuscous 

 but very sparing, a few scattered cinereous hairs at the sides ; 

 on the fifth and apical segments it is fuscous, the margins of the 

 segments obscure testaceous. B.M. 



This very distinct species is not found in the London district ; 

 it appears to be plentiful in Scotland, and has been received 

 from Bristol, but it is not quite certain that the specimens were 

 captured there ; it is more probably quite a northern species, as it 

 is found in Sweden, Denmark and Finland. 



Div. V. Abdomen subpubescent : males only known. 

 39. Andrena picipes. 



A. nigra, pallido-villosa ; thorace fulvescenti ; abdomine fusco; 

 pedibus rufo-piceis. 



Melitta picipes, Kirly, Mon. Ap. Angl. ii. 127. 66. 

 Andrena picipes, Smith, Zool v. 1746. 34. 



Male. Length 4 lines. Black ; the head larger than the thorax, 

 the face covered with a white pubescence ; the mandibles forci- 

 pate. Thorax above clothed with fulvous pubescence, the legs 

 rufo-piceous, their pubescence pale. Abdomen fuscous, shining 

 and pilose. B.M. 



Of this species there is no specimen in the Kirbyan collection, 

 but some suspicion arises that it may be a male of A. helvola.
