2o8 NATIVE BRITISH ORCHIDACE^ 



and H. morio F. ? on cut spikes of O. maculata in a garden at the Cliateau de Sus, 

 Sus, Basses Pyrenees, both with poUinia. 



H.//V///. letico^onius Schr. ? was taken by me in a Surrey garden on 0. maculata. 

 On a cold May evening at Sus, Basses Pyrenees, in 1930, 1 saw a dark object l^dden 

 in a spike of white 0. maculata. It had five polUnia of Orchis mono on its head, and 

 turned out to be Andrena curvungula Thorns, evidently sheltering there for the night. 

 I also saw Bomhus agrorum var. pascuorum visit two or three flowers at Sus, bearing 

 pollinia.
