1G. BOMBUS. j*U9 



the joints of the flagellum are subarcuate, the black band on the 

 abdomen only occupies one segment, and the pubescence of the 

 apical portion of the abdomen is bright ferruginous ; the yellow 

 pubescence is of a paler and brighter colour. The species is un- 

 doubtedly both local and rare. On one occasion I took four males 

 and two females at Southend at the end of August ; it must be 

 observed that the male of B. pratorum appears in May. The species 

 has also been taken on the Brighton Downs and near Bristol. The 

 worker is probably at present mixed with that of B. pratorum.

Female. Length 7-8 lines. — The pubescence black, that on the 

 margin of the vertex, thorax anteriorly, scutellum, the basal seg- 

 ment of the abdomen yellow, that on the three apical segments 

 white ; the scopa on the posterior tibiie ferruginous ; the apical 

 joint of the tarsi rufo-piceous. B.M. 



Worker. Length 5-6 lines. — Excepting size, there is no difference 

 between this and the female. B.M. 



Male. Length 5-6 lines — The pubescence on the face, thorax in 

 front, on the sides, and on the scutellum bright yellow ; the 

 antenna? nearly as long as the thorax ; beneath, and also the fringe 

 on the femora, pale yellow. Abdomen — the basal segment with 

 yellow pubescence, the second, third, and base of the fourth seg-

Var. ft. The two basal segments yellow. 



Var. y. The first and base of the second yellow. 



Kirby's type of A. jonella has the basal segment entirely yellow. 

 All *he sexes were obtained from a nest found on the Grampians, 

 Perthshire. This is a somewhat local species ; it has been taken at 

 Coombe Wood, on Purlcy Downs, Shirley Common, and at Barmouth, 

 North Wales. Mr. Kirby's description is incomplete, so that it was 

 difficult to ascertain to which species this male should be assigned ; 

 but having myself seen his own interleaved copy of the ' Mono- 

 graphia,' I found that he had subsequently added, " Facies ante an-
