342 HYMENOPTERA ACULEATA. 



and new world, there is only one British representative, 

 which is very unlike any other of our bees. The $ 

 is as a rule much larger than the ? , the maxillary palpi in 

 the British species are two-jointed, the labial palpi four- 

 jointed, the second joint slightly shorter than the first, 

 the maxillEe are pointed, somewhat resembling those of 

 Goblioxijs, the scales at their base well developed ; the 

 labrum is elongate^ its sides slightly rounded ; wings with 

 two submarginal cells, scutellum produced over the meta- 

 notum, abdomen with yellow spots, c? with the seventh 

 dorsal segment more or less spinose, six ventral segments 

 exposed, clothed with long hairs, eighth with a narrow 

 apical process, armature with the stipites short and curved ; 

 ? with a ventral scopa composed of simple hairs. Smith 

 says that A. manicatum has never been known to make a 

 burrow of its own, but employs those made by other 

 insects, which it lines with the woolly coating of the stems 

 and leaves of certain plants which it scrapes off with its 

 mandibles, rolls up into a ball and carries off to the nest; 

 the cells are enclosed in a semi-transparent membrane. 



A. manicatum, Linn. — Black, head and thorax closely 

 punctured, clothed with short yellowish-brown hairs above, 

 with nearly white hairs beneath ; mandibles except at the 

 apex, a bilobate spot on the clypeus, the cheeks below the 

 antennie, and a small spot behind each eye yellow ; thorax 

 with the tegulai yellow in front, wings slightly dusky ; 

 abdomen black, clothed with erect greyish brown hairs, 

 and with a band of denser, browner hairs at the apex of 

 each segment, the lateral margins of the segments in the 

 (J with fringes of curved golden hairs, each of the first 

 four segments with a yellow spot on each side, larger in 

 the c? than in the ? , the fourth has usually also two other 

 discal spots between the lateral ones, the fifth has two or 

 four spots in the c?, and two elongate transverse spots in 

 the ? , the sixth in both sexes bears two discal spots, which 

 are transverse in the (J, the sixth and seventh segments iu
