pelagos further north. The Rhynchophora comprise by far the

The authoFs conclusions are : — 1 st. That the difference in flexi- 
bility of the two margins of the wing is not sufficient to com-

pidly than it is elevated ; and 4th. That the extent of the sur- 
face of the wing is larger in the movement of lowering than in 
that of elevation.
