Sleep, which resembles a return to the peace of non-existence, is, like waking, an effort, here of the leg, of the curled tail; there of the claw, of the jaws.
The transformation is effected about the middle of May, and the adult Empusa makes her appearance.

She is even more remarkable in figure and attire than the Praying Mantis.

Of her youthful eccentricities, she retains the pointed mitre, the saw-like arm-guards, the long bust, the knee-pieces, the three rows of scales on the lower surface of the belly; but the abdomen is now no longer twisted into a crook and the animal is comelier to look upon.

Large pale-green wings, pink at the shoulder and swift in flight in both sexes, cover the belly, which is striped white and green underneath.

The male, the dandy sex, adorns himself with plumed antennae, like those of certain Moths, the Bombyx tribe.
