504 Araujia Albens as a Moth-Trap. [June 
the nectar, first reaches that portion contained in the pockets 
between the bases of the spurs; then in search of more, having 
already thrust the proboscis down the tube of the flower, de- 
scribing a curve between the exterior of the stamineal crown or 
mass and the inside of the bulb of the perigonium, it then has 
to push the proboscis upward in order to reach.that portion of 
the flower where the anther-cells, pollen-masses, and glands are 
in close juxtaposition. Having satisfied its hunger, or otherwise, 
upon attempting to withdraw the proboscis, as the moth can 
only make a direct pull, it (the proboscis) not being provided 
with any muscular arrangement by which the curved motion 
made in entering, as just described, can be reversed,—to repeat: 
upon attempting to withdraw its proboscis, dy a direct pull, it 
becomes wedged in between the edges of what may be termed 
_ the anther-wings, or, rather, the edges thereof, and is held tight, 
very much in the same way that an old-fashioned boot-jack grips 
a boot. The more the moth pulls, the tighter or firmer the grip, 
and escape is impossible, unless the flower has reached such 
a degree of maturity that its substance has become somewhat 
_ softened or wilted.
