narrow, and not nearly filling the whole of the apical impressions, 

 which to a large extent are clothed only with the minute hairs of the 

 general surface and a row of setae springing from the base of the

A male from the New Forest, which I susjjected would prove to be 

 Jlavipes, and by examination of the genitalia found to be this species, 

 has the penultimate antennal joint reddish beneath, but much darker 

 than the 11th joint, while the apical joint is hardly pale at all. In 

 Bliithgen's table the two apical joints of this species are said to be 

 yellow beneath. Similarly there seems to be considerable variation in 

 the colour of the legs and of the metallic tint of the head and \)0(\y. In 

 the J the mesonotum of jlavipes is said to be much more finelj^ and 

 densely punctured than in fumulorum, but this is not the case with my 

 specimens. This author considered the descriptions of iumulorum 

 in Saunders's work to apply io Jlavipes rather than to the other.

A male examj^le of this veiy scarce bee* was taken on a Hower head 

 of Centaurea nigra growing on the roadside between Dunstable and 

 Tring on Jvily 29th, 1921 ; another individual of the same sex was also 

 observed but not captured. The local it}^ is situated on the chalk, and 

 nvunbers of freshly emerged Lycaeria corydon were on the wing at 

 the same time, while odd specimens of Ortholitha hipiinctaria flew 

 up among the herbage. The example of the bee which was captured 

 was in perfect condition and had evidently only very recently left the 



* I am indebted to Rev. P. D. Moi-ice for ezamimng the specimen and confirming my 

 identification thereof.
