black ; anteriorly, posteriorly, on the sides, beneath, and also on 

 the legs it is pale yellow ; the tarsi beneath have a short ferrugi- 

 nous pubescence, the claws ferruginous. Abdomen — the basal 

 segment clothed with pale yellow pubescence, most dense at the 

 sides ; on the second segment it is black, the posterior and lateral 

 margins fringed with pale yellow; on the third it is black, the 

 margins being fringed with pale yellow ; on the three following 

 segments it is fulvous, the margins being fringed with pale hairs. 



B.M. 



Worker. Length 6-7 lines. — Differs very little, except in size, from 

 the female ; it has, however, usually a greater mixture of pale 

 pubescence, and the apex of the abdomen is not so bright a red. 



B.M. 



Male. Length 6 lines. — Closely resembles the other sexes ; the 

 mandibles fringed with fusco-ferruginous hairs; the antennae as 

 long as the thorax, and the apex of the abdomen usually as bright 

 as in the female. B.M. 



This bee is found in all parts of the United Kingdom, and is one 

 of the most constant in coloration; the hum of its workers is 

 distinct from, and more shrill than, that of any other Bombus ; it 

 closely resembles that of Saropoda bimaculata. I once found a nest 

 of it underground ; it had taken possession of a cavity, and built a 

 nest in it of moss, grass, &c, in the same way as when following its 

 normal habit of building on the surface.
