Female. Length 9-11 lines. — Densely clothed with black pubes- 

 cence, the collar orange-yellow ; wings subhyaline, their apical 

 margins clouded. Abdomen — the second segment with bright 

 orange-yellow pubescence, that on the third and fourth black ; on 

 the apical segments it is fulvous yellow. B.M. 



Tar. /3. The apical segment of the abdomen with white pubescence. 



Worker. Length 5|— 7 lines. — Closely resembles the female ; but the 

 yellow bands are frequently of a paler tint, arising principally from 

 exposure, and the apex has a white or tawny-white pubescence ; 

 it has always in recent examples a mixture of fulvous hairs at the 

 margin of the black fascia. B.M. 



Male. Length 7-8 lines. — The pubescence on the head entirely 

 black ; the collar and second segment of the abdomen with orange- 

 yellow pubescence, that at the apex of the abdomen tawny, but 

 paler than in the female, occasionallv white at the extreme apex. 



B.M. 



The female is larger than that of B. lucorum. This species is 

 found in all parts of the kingdom. Its nests, as far as my experi- 

 ence enables me to judge, are more populous than those of any other 

 species (perhaps B. la/ddarius excepted) ; in one nest I found 107 

 males, 56 females, and 180 workers ; and some of the latter sex 

 were probably on the wing when the nest was taken — late in the 

 evening in the month of August. Apathus vestalis lives in company 

 with this species. 



17. Bombus hortorum. 



B. hirsutus, ater : thorace antice, scutello abdominisque basi fiavis, 

 a no albo ; capite elongato.
