 Melitta nigriceps, Kirby, Mon. Apum Angl. ii. 134 (nee <$). 



Female. Length 5 lines. — Black ; the pubescence on the head 

 black ; on the posterior margin of the vertex a thin fringe of ful- 

 vous pubescence ; the flagellum nigro-piceous beneath. Thorax 

 densely clothed with rufo-fulvous pubescence, paler on the rneta- 

 thorax and sides ; the tegnlrc ferruginous ; the wings hyaline, their 

 apical margins faintly clouded, the nervures ferruginous ; the legs 

 have a black pubescence, the apical joints of the tarsi rul'o-piceous. 

 Abdomen ovate, subdepressed, the four basal segments with a 

 broad fascia of fulvous pubescence ; that on the fifth and apical 

 segment is black. B.M. 



Male. Length 4 lines. — Head, the face densely clothed with black 

 pubescence mixed with a little brown on the vertex ; the man- 

 dibles fringed with reddish brown pubescence. Thorax closely 

 punctured, and sparingly clothed with reddish brown pubescence, 

 much paler on the metathorax and sides ; the legs similarly clothed. 

 Abdomen thinly sprinkled with pale brown hairs, which are most 

 dense on the three basal segments ; the apical margins of the second 

 and following segments fringed thinly with pale pubescence. B.M. 



This is by no means a common species : it is found during Julj r 

 and August ; its known localities are Kingsdown, near Deal ; Pake- 

 field, near Lowestoft ; Household and other places in the neighbour- 

 hood of Norwich ; also Barmouth, North Wales, and Ilfracombe, 

 North Devon. There is no specimen of the male described by Mr. 

 Kirby in his type collection ; but as he says " taken in April," it is 

 very probable that it did not belong to this species, but was a male 

 of " bimaculata " without the red spots.
