Female, Length 8 lines. — The pubescence black ; the thorax 

 above before the insei'tion of the wings, the scutellum, and the 

 two basal segments of the abdomen^ yellow; the three apical 

 segments of a fulvous-yellow. B.M. 



Male, Length 6 lines. — This sex differs in having the pubes- 

 cence longer than in the female ; the face has a yellow pubes- 

 cence, and the black band on the abdomen occupies the third 

 and fourth segments ; the body beneath entirely covered with 

 long pale pubescence. B.M.

Professor Boheman says this species differs in having the 

 apex of the abdomen sometimes fulvous and at other times 

 yellow 'y Dr. Ny lander also points out these varieties ; the yellow 

 bands are also sometimes less bright and distinct. These va- 

 riations constitute three of Dr. Dahlbom's species, as shown 

 above. 



This fine addition to our fauna w^as made in 1852 ; it was dis- 

 covered at Lerwick, in Shetland, and is the second species of 

 Bombus, previously unknown as British, which has been received 

 from the same locality. Were this group of islands well searched 

 bv some competent entomologist, there can be little doubt of 

 still further additions being made, — in all pix)bability B, alpinus 

 amongst the number.
