second and third segments laterally, and continuously on the fourth is 

 a narrow fascia of white hairs ; the apical fimbria is rufo-fulvous ; 

 beneath the second segment is red. 



Var. 2. — Only the margin of the first and base of the second seg- 

 ment of the abdomen red. 



Var. 3. — Abdomen black, the margins being only very obscurely 

 ferruginous. 



Male. — (Length 6j lines). Black, the antennae piceous beneath, the 

 clypeus white, with two black dots; the thorax has a thin griseous 

 pubescence, sparing on the disk ; the tarsi ferruginous. Abdomen ob- 

 long-ovate, the margins of the segments slightly piceous and depres- 

 sed, with a pale fulvous pubescence at the tip. 



This fine insect is the largest of the genus. Variety 1, is the Me- 

 litta Lathamana of Kirby, it is rare, the insect being generally found 

 altogether black. I once took this bee at Birch Wood, and also once 

 at Darenth Wood, Kent; I have known it to be taken three or four 

 times at the latter place, but not in any numbers, only three or four of 

 the red-banded variety have come to my knowledge, one of which I 

 captured myself in the beginning of August, 1839.
