EDNOTE. Akiko tells me that Boyd has
recognized the reference to the Spinx or Hawkmoth in the phrase.
That l'aiguillon rouge specifically refers to the red horn sticking up on the
last segment of the caterpillar. More immediately, the phrase refers
to the receptionist's finger and nail polish as she signals HP. It is not a
stinger. I have not been able to discover what its function may be. Perhaps a
sex attractant?
