Note 10 — ENTOMOLOGY. PLATE XII. PAPILIO EGÆA EGÆA’S BUTTERFLY. Order Lepidoptera.

We have lately understood that the editors of Encyclopædie Methodique, now publishing in Paris, intend giving figures of the Papiliones of the Equites family, which Fabricius has described. This endeavour to illustrate Fabricius is under the direction of Mons. Latreille, a Member of the National Institute, an Entomologist himself, of acknowledged talent, and one to whose great ability, as well as personal urbanity, we are happy to bear our testimony of praise. In the absence of more conclusive authority, the conjectures of Mons. Latreille would be, unquestionably, useful; but we shall, ourselves, tread the same path, and as we trust, may assist also, in no small degree to dispel the darkness which at present overshadows this fair portion of the science. As we are, ourselves, possessed of the authentic evidences, by means of which, the species of Fabricius can be immediately identified, we have no occasion to wander into the labyrinths of conjecture: we at once arrive at the certainty of truth. The annunciation of this design, on the part of the French editors, leads to a conclusion of the importance attached to this endeavour: it need be only stated on our part, that the illustrations we shall subjoin to such of the Fabrician species as may pass under our own observations, will be precisely taken from the individual objects which Fabricius has described.
