A glance at the figures of this table, furnishes evidence of the 
important part, taken by bees in the fertilization of these flowers, 
as the visits recorded above give an average of 83% in favor of 
the bees. The species adapted to the smaller bees are also fre- 
quently visited by bumble-bees, and on the other hand the smaller 
bees pay much attention to the bumble-bee-flowers. The absence 
of wasps from these flowers is worthy of mention ; I have not 
witnessed the visit of a single wasp to any of these honeysuckles. 
The latter seem to be rather attractive to the hummingbird, this 
visitor having been observed on all our species, with the exception 
of L. ciliata, the first of our honeysuckles to appear in spring. 
NOTE— It affords me great pleasure to express my thanks to a number of 
gentlemen, wno have kindly aided me in various ways in connection with this 
paper: To Mr. J. A. Brandon, the treasurerof our society, who made the draw- 
ings of the flowers, reproduced on the accompanying plate; to Mr. Wm. H. 
Ashmead and Mr, D. W. Coquillett, both from the division of entomology of the 
Department of Agriculture, Washington, D. C, for the courteous help given 
me, in determining many of the hymenopterous and dipterous insects taken on 
the flowers.
