 the humblebee, and we may well hazard the 

 prophecy that the Bombus is the welcomed affini- 

 ty of the flower. 



The diagrams (Fig. 4) sufficiently illustrate the 

 efficacy of the beautiful plan involved. At A 

 the bee is seen sipping the nectar. His forward 



movement thus far to this point has only seemed 

 to press the edge of the anther inward, and thus 

 keep it even more effectually closed. As the bee 

 retires (B), the backward motion opens the lid, 

 and the sticky pollen is thus brought against the 

 insect's back, where it adheres in a solid mass. 

 He now flies to the next Arethusa blossom, enters 

 it as before, and in retiring slides his back against 

 the receptive viscid stigma, which retains a por- 

 tion of the pollen, and thus effects the cross-fer- 

 tilization (C). Professor Gray surmised that the
