 The synonymy of this species is, I think, undoubtedly correct. In 

 addition to the discovery of several nests, whence I obtained the sexes, 

 I captured three pairs in coitu. The species is extremely abundant 

 at Southend and at Walmer, in Kent. I have received the species from 

 Denmark as a variety of B. Hortorum, that is, female and worker, the 

 male being correctly named B. Latreillellus.

This species is extremely variable in colouring ; the most highly 

 coloured, B. ruderatus, has the thorax in front, the scutellum and the 

 base of the abdomen yellow ; every shade of difference occurs between 

 this form and one entirely black. The variety with the apex of the 

 abdomen whitish and otherwise end entirely black I formerly con- 

 sidered the B. soroensis of Fabricius. It will probably be questioned 

 whether I am justified in considering the B. Harrisellus a variety; 

 indeed Nylander gives it with doubt in the revision of his Apis bore- 

 alis ; one reason for my doing so is based upon the fact of my being 

 unable to distinguish any difference in the form of the generative organs
