Dr. Anthony considers each of I In e ear Like appendages to be a minute sucker, either for the ail I lesion of the fleshy in-, or for tin- imbibition of fluids, or perhaps for both purposes.

Themanner, says Mr. Newport, in which the honey is obtained whenthe organ is plunged into it at the bottom of a flower is by a constant succession of short and quick extensions and contrac-tions of the organ, which occasion the fluid te accumulate upon itand to ascend along its upper surface, until it reaches the orifice ofthe tube formed by the approximation of the maxilla? above, and ofthe labial palpi and this part of the ligula below. By the plan of conformation just described we are led to thatwhich prevails among the Lepidoptera, or butterfly tribe, which,being pre-e
