The preceding table gives the insect visitors of Lonicera a 
observed in different regions. 
LONICERA SULLIVANTII Gray.—This honeysuckle occurs in 
two places in my neighborhood, on creek banks. The flowers 
are in clusters at the ends of the branches and hold a more or 4 
less horizontal position. Newly opened ones are rather pale 
yellow, but later show a purplish tinge. The upper lip consists 
of four lobes which are turned up like a vexillum; the lower 
consists of a single lobe. Bees land upon the stamens and 
style, which are exserted about 7™", The corolla tube measures 
14-18" in length. Nectar is secreted and retained in a slight 
gibbosity near the base of the tube. 
The flowers are homogamous, the stigmas are receptive # 
little before the opening of the anthers, but the proterogyay ® 
too slight to be of much importance. The stigma is somewhat 
in advance of the anthers, but not enough always to prevent 
spontaneous self-pollination. 
I have observed flowers opening as early as 4 shee 7 
the afternoon, the anthers beginning to open at 5:15 o'clock, 
and most of the flowers shedding pollen by 5:30 pe 
flowers were visited by Bombus virginicus Oliv. 9, threes A ¢ 
phora ursina Cr. 2 and the humming bird, Trochilus colubris L 
that there was abundant opportunity for them to be eff a 
pollinated before sundown. The work of pollination may ee 
completed by hawk moths in the evening, or when the 
humming birds return next morning. Thave see
