ing is a moustache-shaped appendage which possesses stiff hairs 
all of which point toward the pitcher opening. ‘The color of 
the pitcher is green, blotched esa ; 
with red and yellow. Within 
and about the opening and on 
the bi-lobed appendage are 
alluring glands which secrete a 
nectar attractive to insects. 
The nectar is also secreted* by 
glands along the wing. An 
insect creeping over the exterior 
of the pitcher is enticed to the 
nectar along the wing which it 
follows up to the orifice where 
the honey is sweetest. Flying 
insects are attracted to the 
pitcher by its mottled and 
colored features. They alight 
on one of the flaps of the appen- 
dage and follow its curve which 
narrows to the orifice. Sharp 
bristles in the path pointing 
toward the orifice make it the 
natural direction for the insect 
to travel. Upon reaching the 
end of the path, it is tempted 
farther by honey glands within 
the opening of the pitcher

ing by which it entered. The insect sees no means of escape, 
nothing but hairs on the inner surface of the pitcher pointing 
downward and which direct it to the dark detentive pit below, 
where it drowns in the watery secretion.
