Book excerpt: Excerpt from An Essay on the Development of the Mouth Parts of Certain Insects In a well-developed mandibulate mouth we have, forming an upper lip, the lab rum, often notched in front or toothed; but never a paired organ, never with appen dages, and never mechanical in function. It is articulated at base to the clypeus and serves to shield or protect the mouth in front; as a matter of fact, not a functional mouth structure at all. It is marked 1127' in all figures.
