Perhaps this is the most widely distributed species in the 

 genus : it is found ihroughoul Europe, and Dr. Richardson 

 took it at Lake Winnepeg, in the arctic regions.

 The female described by Mr. Kirby, and also the var. jS., 

 are specimens of B. subterraneus ; the var. y. is a female of 

 B. Lalreillellus, and all the other varieties belong to the 

 same species. This Bombus may always be distinguished, 

 that is the female and worker, by the shortness of the 

 pubescence on the abdomen, and by the margins of the 

 first and second segments being thinly and somewhat 

 indistinctly fringed with pale hairs. I have during the past 

 season taken all the sexes from the nest : it builds under- 

 ground ; usually its nest is approached by a tunnel a yard or 

 even more in length : it is very abundant at Walmer, in 

 Kent : its nests are usually found in banks. The Apathus 

 vestalis is parasitic upon it.
