80 BEES OF GREAT BRITAIN. 



pubescence, and the three following segments having a fascia 

 of the same ; the apical fimbria rufo-fuscous. 



Male. Length 4 lines. The face has a dense white pubescence ; 

 on the thorax it is ochraceous, very pale on the sides and 

 beneath ; the wings hyaline and iridescent ; legs as in the fe- 

 male ; the abdomen lanceolate and covered with a long, dense, 

 pale yellow pubescence. B.M. 



Having carefully examined a large number of this species, it 

 appears certain that A. rufitarsis and A.fuscipes are the same, 

 the former being merely a brighter variety, frequently met 

 with on the first appearance of the insect : Mr. Kirby himself, 

 subsequently to the publication of his ' Monograph/ was of the 

 same opinion, as in his own interleaved copy there is a note to 

 that effect. M. pubescens of Kirby is the male, but whether it is 

 synonymous with the Apis pubescens of Fabncius admits of 

 some dout)t. This bee appears to confine itself to open sandy 

 heaths ; it abounds on all the heaths in Hampshire during July 

 and August ; it is also very common at Weybridge, where it 

 forms large colonies ; it must be borne in mind that exposure 

 soon bleaches bees of a fulvous clothing, and this, which de- 

 lights in the sunniest weather, is frequently met with quite grey, 

 the males being sometimes white. This species seldom frequents 

 any flowers, except those of the purple heath.
