varieties have been described as constituting seven species ; the 

 normal colouring of the female is Kirby's A. subinterrupta, and his 

 A. burrellana that of the male. I have examined many nests of this 

 species, which are frequently found in hay-fields, on mossy banks, 

 and under furze bushes ; they make little or no defence of their 

 nests when they are disturbed. Apathus barbutellus is parasitic on 

 this species.

Female. Length 5-6| lines. — The pubescence black ; the anterior 

 part of the thorax in front of the insertion of the wings with a 

 dense bright yellow pubescence ; wings fusco-hyaline, their apical 

 margins with a fuscous cloud. Abdomen — the basal segment 

 clothed with black pubescence, that on the second of a bright 

 citron-yellow, on the third it is black, and that on the three apical 

 segments bright rufo-fulvous. B,M. 



Male. Length 5|-6| lines. — Densely clothed with pale yellow 

 pubescence, with a few black hairs on the face at the insertion of 

 the antennae ; the joints of the latter subarcuate. Thorax — a 

 fascia of black pubescence between the wings ; the tegulse rufo- 

 piceous ; the wings as in the female ; beneath, with long pale 

 yellow pubescence ; that on the legs is a mixture of pale and black. 

 Abdomen- — the two basal segments with pale yellow pubescence, 

 the third with black, and the following segments with bright fer- 

 ruginous. B.M. 



I was formerly led to consider the male of this species to be a 

 highly coloured variety of B. soroensis ; but having captured speci- 

 mens I have been enabled, by an examination of the sexual organs, to 

 satisfy myself that they are distinct species. I have not any positive 

 evidence of the female described being really that sex of the species ; 

 but as it has been taken at the same time and place as the male, and 

 as no any other species of Bombus is known to which this female 

 could be assigned, I have no doubt as" to the correctness of my con- 

 clusions. The female most closely resembles that of B. pratorum, 

 but can always be distinguished by the abdomen being shorter and 

 broader, and by the black band occupying one segment only. The male 

 resembles that of B. pratorum ; but the general pubescence is shorter,
