comes into flower as the snow melts from off it, and dots _ 
und in great abundance. The tube of the corolla is 10— 
long: each plant is either long-styled or short-styled, the Siete 
tube of the short-styled being on the average about 2 mm, lon- 
ger than that of the long-styled. The flowers were seen to be 
visited by a Hymenopteron and two Lepidoptera, though somewhat 
sparingly. They contain a very little honey. Apis indica ascends 
bee was seen to hesitate before an inflorescence, examining it, 
and then to turn away without settling. 
The flowers of Viburnum fetens are scented and contain 
a moderate quantity of honey. They chiefly face downwards. On 
their own then leafless branches and among the still leafless Acers 
of the forests, they are aes conspicuous. <A large Bombus was

whitedlowered plant—Lonicera angustifolia. It gets the visits 
of the Bombi, which do not penetrate much into the shade: 
in tunicatus was several times seen on its flowers, going from 
one to another and from one bush to another without changing to 
any other plant: it was seen at work from sunrise to sunset. 
Apis indica was also a common insect upon the Lonicera flowers. 
The Lonicera flowers are pendent, most commonly obliquely 
so, as represented in my figure (fig. 1), but varying in some 
degree between being horizontal and vertically pendent. Their 
duration is some time more than 48 hours. They open for the 
most part towards evening, the anther towards the twin flower 
dehiscing first, and the others following in pairs, the more remote
